Just to thank you enormously for you help and patience in getting us to the finish line on these two windows. I did actually need my building guys just to optimise the positioning and fashion the trim - but the dimensions were perfect (especially midrail position) - so thank you so much.

I don't vey often take time to follow up on a purchase. But now we have fitted your secondary glazing, I think you should pass on our comments to you colleagues. The product is excellent, quality and manufacturing tolerances are superb ; your customer service is excellent, your website, in particular the measurement guide and the fitting guide is first rate.

My second purchase from Clearview, 17 units in total and no complaints from me. As before all units were manufactured with precise accuracy with the same overall quality of the frames and glass. Delivered on time by a very helpful/friendly driver. Just the final finishing to complete but I can already feel the benefit with a reduction in road noise. No doubt that when winter arrives I will also have the benefit of better insulation. The service level of this company and their products are first class - recommended.

Just wanted to say thank you for my order for secondary double glazing and fly screens. It has now been installed, and everything is absolutely perfect, and without any negatives whatsoever. The fit is perfect, the mechanism for the sliding screens is smooth, the glass and overall quality of the unit is first class, and they do the job they are designed to do super efficiently. Thank you too for all the help and clear advice you gave prior to ordering, which enabled us to make an informed decision. The ordering, payment, communication and delivery service was all 5* excellent. A big thank you all round. We are super pleased with them.

Delighted with my new window . It is in my ensuite bathroom and fitted perfectly and it seems warmer at once. Outer Window was the first to be replaced by Anglia with double glazed unit. It has never been very good however now Triple glazed it is much better. I will order another window to Triple Glaze the back bedroom. It will be a triple horizontal slider.

The secondary glazing has been installed for a couple of weeks now and it has made such an amazing difference to the heat retention in the room. You really can't see the secondary glazing; it matches the existing window so well. It looks good, it works, I'm spending much less in fuel to heat the room and for one person at least 2020 is not ending in tiers.

Just thought I'd write to you and tell you how pleased we are with the three windows we received from you. Put them in over the weekend, which was straightforward, and now we can hear the difference from the road outside. No longer car engines, just a hum or hiss. We were able to give a 5 inch airgap to the back of the exterior double-glazed windows, and the secondary frame and panes are not in the least obvious. We'll be ordering from you for the other two windows on the road side of the house very soon.

I just wanted to say how pleased I was with both the quality of the windows and the service I received when ordering them. They fitted simply and were a pleasure to install too. It’s always a worry when buying things blind on the internet, but I can honestly say that I’m 100% happy with everything. Even my wife said what a difference they make and visually, you hardly notice they are there.

Best investment in my property so far! I live in a Grade II listed building, which was built in 1850, so double glazing is not permitted. I have single-pane sash windows which used to have a lot of condensation on them, rattled as the draughts came in and were useless against noise. Luckily, I discovered Clearview at the end of last year. The ordering and delivery were easy with excellent communication throughout. Since I fitted the units condensation has been eliminated, no more draughts and external noise has been greatly minimised. The windows are well made and easy to install. They’re so good I’ve yet to put the heating on this year

Can I say how pleased we all are with the secondary glazing at The Cottage, Badminton. The windows in the Library, Office and the lockable lift outs for the skylights look really good. Please thank Wez & Dan for me for all their hard work and in keeping the Cottage tidy whilst fitting. Many thanks to you as well for putting our minds at rest from the start of the project. The Cottage is now warm and toasty with new heating and wood stove installed in the library. What a transformation!!!

Clearview customer service is outstanding. This is an excellent product that can be installed by any competent DIY'er. My units are single pane hinged double glazing and fitted in a listed building. They are invisible when viewed from the outside and so unobtrusive on the inside.

From the start I was confident about this company. I had a non standard requirement and they spoke at length about it. Furthermore they arranged for a delayed and specific delivery to fit in with my availability. I was able to fit and trim the unit in 2.5 hours and for anyone with DIY skills it is easy enough. It has reduced noise considerably despite not being at the recommended distance from the existing window. It is also invisible! I have attached photos and it is difficult to see the additional unit! Highly recommended this company.

From start to finish, our dealings with Clearview Secondary Glazing could not have been better! They proved to be a thoroughly professional business, who carry out an all round first class service by not only providing and installing a superb product but also by explaining everything in non-ambiguous terms; keeping the customer informed at every stage; turning up when they say they will and for being, well, just very nice people! Worth every penny! Thank you very much Andrew and Craig (and those behind the scenes we didn't get to meet!)

I'm completely made up with my new Clearview Secondary Glazing windows. Not feeling confident with your DIY skills? Fear not, as from start to finish I felt totally supported by the team at Clearview SG. I had loads of questions about the process (measuring, ordering, installation etc) but no question was ever too much trouble for them. I made a few mistakes when measuring, but they check, double check and triple check before they begin manufacturing. The windows look great and work perfectly. I would recommend them to anyone. Thanks heaps to Andrew, Deborah and the rest of the team. Brilliant!

I would like to take the opportunity of thanking all at Clearview for the supply of my secondary glazing units. We have an older style house with aluminium framed double glazed windows in hardwood surrounds and although they suit the property they are not as efficient as modern glazed windows. We didn't want to upgrade the windows as UPVC frames would look wrong. I had fitted some DIY Polycell units many years ago but decided that we would now like to do the job properly with toughened glass and the ability to open the centre panel only to get to the fanlight, these 3 panel sliding units really do the job. After a lot of online searching we chose Clearview and am so pleased we did, the service has been great, from the online quote to placing the final order, we have been kept in touch all of the way even to the delivery driver phoning to fix a delivery time. I have finished the installation and would have no difficulty in recommending both your product and your company. Many thanks David Terry.

I would just like to say what a fantastic product the Clearview secondary glazing has been in our bedroom, without going over board it has improved our quality of life literally overnight, we have spent a lot of years complaining about traffic and human noise from outside and the secondary glazing has pretty much solved the problem, not to mention the lack of condensation. Great solid product and helpful advice from your staff. Easy to fit from a lay mans point of view, I have decided to go with another 2 windows down the noisy side of the house, will be in touch.

We wanted to express our sincere thanks for making the whole process run so smoothly - from our initial contact with you, through to the actual installation of the units. Throughout the entire planning stage, you have been extremely helpful and courteous. And, in relation to the actual installation, we have absolutely nothing negative to say. They were polite, professional, worked hard to keep any disruption to a minimum, readily answered any questions we had (of which there were a few) and, to sum up, it was a pleasure having them in our home. By the time they were ready for leaving, they had done such a good job cleaning up after themselves, that the only thing to show for their visit was the fact that we now had our wonderful secondary glazing in place. And, on this note, we are absolutely thrilled! Other than the obvious benefits from the sound insulation, you wouldn't know the windows were there - they are so unobtrusive, it's incredible! It has made a huge difference in cutting down the noise from the traffic, and also noise (previously heard, but no longer) from people going past, or from youngsters playing out.

Our bedroom overlooks a railway line, so we were primarily looking for acoustic insulation (we’d had secondary glazing in our last home, so knew how effective it was). After some online research, we went with Clearview this time, as their prices are competitive, their online quotation system quick and easy, and – perhaps most importantly – their customer service responsive and helpful. As it happened, here were a couple of glitches (on my part) with measuring and specifying, which Andy at Clearview ironed out for me with no fuss. Once ordered, the product arrived on time, and has proved highly effective at reducing the noise. I actually enjoy watching trains go by in near-silence, and have since ordered a similar unit for our living room, to repeat the experience! I can thoroughly recommend secondary glazing in general, and Clearview in particular.

The lounge is much warmer since secondary glazing was fitted, and the condensation has stopped. We have also noticed a reduction in noise from the main road outside. We really like the fact that the secondary glazing does not detract from the look of the bay, inside or out. We don’t notice it.

We had secondary glazing fitted in January, and immediately noticed the benefits. Our dining room is much warmer, and quieter.

Good quality windows, acoustic glass does the job well.

Not the cheapest, but all in all great service, would recommend to anyone.

I've just finished a self-fit project on our listed cottage, of a mixture of horizontal sliding and lift-out units. The team at Clearview were helpful and efficient throughout, fitting instructions and tips were comprehensive and clear, and phone queries were answered promptly, with helpful advice and suggestions. The resulting sound insulation is remarkable - we live next to a sometimes noisy pub - and the outside appearance is unchanged. Inside the finish is neat and one hardly notices that there is secondary glazing there. Very satisfied.

Fitting was a breeze – if you can handle a screwdriver, you can fit them yourself. Immediately noticeable was the reduction in traffic noise from the fairly busy road. The added bonus of the extra insulation they provide is noticeable too, but best of all, after 4 nights now, I have not had a single drop of condensation on the original double-glazed windows yet. Anyone considering buying these but having second thoughts or doubts? Don’t delay any longer. Not only is it a great product, but the sales staff were very patient and helpful with me at the start of the process.

What the company offered was perfect for us because we wanted to retain the external character of our home, while keeping heat in, and noise out. Megan’s room is at the front of our house, and she has alway been a light sleeper, so sounds of cars and dustbin lorries were constantly waking her. But since the secondary glazing has been fitted she has slept much better.

Living next to a busy road, the double glazing had little or no effect on cancelling or reducing road noise (plus the odd conversation below in the street). I decided to look at Secondary Glazing after doing some shopping around and quotes I got for 4 x windows.. I went for Clrearview as it was easy to get a quote based on what I needed and size and cost seemed reasonable.. Once the sizes were confirmed by the installer and FAQ’s answered, the windows were installed 2 months later. They were installed within about 3-4hrs and I must admit, the noise reduction has been noticeable.Although far quieter, I still get some road noise but that’s from large trucks, sirens from police, ambulance vehicles and the odd car with the large can exhaust but otherwise, more than happy with the results. Peaceful nights and can listen to the TV/music without the background noise of a passing car etc.The process is all by email and website but payment is easy and Aaron (who was the main POC) was extremely helpful and replied almost immediately.Also, far more competitive in price than other leading window companies….!

Process of ordering is simple. Being in an old house all our window recesses are slightly different and the process makes it really easy to adjust the order to the exact sizes I need.Windows all arrived exactly as specified and I've been kept up to date on scheduled delivery times so I can ensure that I'm at home when they arrive. Drivers have all been very courteous and happy to carry the windows to wherever needed.The windows themselves are saving us a lot of heat and look much better than some very old aluminium framed ones we had previously. In fact they are so good visitors don't even notice we've put them in. They are very easy to install and took me minutes to get up before adding the trim which takes a little longer as it all needs cutting to fit.Overall, excellent product and service.

Purchased acoustic secondary glazing on two occasions - absolutely excellent service from beginning to end and a fantastic quality product. The acoustic glazing has worked like magic and made our bedrooms into an oasis of peace and quiet from outside noise, with the additional benefit of helping keep the rooms warmer in winter and cooler in summer. Highly recommended.

Bought 2 x tilting vertical sliders for the front sash windows of our grade 2 listed house. We are very happy with them - they have transformed the lounge from a cold noisy space to a warm quiet room where we are happy to sit in the evening. They look great (hardly noticeable from outside) and operate exactly as described.The ordering process was clear and easy to understand - we measured the frames twice each, then compared notes and measured them again - getting the right measurements is vital.Phoned to ask a couple of questions I wasn't sure about and spoke to a glazing salesman with good product knowledge - a rarity in the glazing industry!The frames arrived on time and in good condition and were easy to fit.100% recommended.

Easy to order, arrived before expected time of delivery. Arrived fully assembled. It was easy to fit. Only negative is that no screws arrived with the package and the frame was not pre-drilled. I would definitely order again, very reliable company.

We ordered the 3 secondary glazing units for our bay window from Clearview, near winters end. These soon arrived in perfect condition. Sizes checked & all as ordered, with tolerances built in. I have just fitted the 3 glass units in the last 2 weeks, now that the weather is warm & dry. Great help from Clearview, making sure all detail was right, before starting. The new units are now completely sealed & total silence. Looking forward to warmer winters & cutting out the Siberian blasts. Very impressed with the efficient service. Many thanks, AP

The process of ordering online was very easy, I found everything I needed to help me, on their websites with all their extensive guides and various options.We waited nearly 3 months for our two-bedroom windows as they had supply issues, but having said that it was worth the wait.We live on an extremely busy road, with traffic lights directly outside our home, which would lead to loud music, wheel spinning while the lights are on red, the list goes on, not forgetting next door but one to a pub!My wife and I have been suffering from a lack of sleep for a while, I work shifts also. The windows have dramatically cut the noise out, I went with 6.8 acoustic glass and a 280mm gap, fitting was easy down to good prep at the measuring stage, which I think any competent DIY's following Clearview guides can achieve. I'll be honest we were going to sell our home which we love, if the windows didn't help, so thank you.

After asking for some help with the measuring, we ordered a bay window which fits superbly, and has made a really noticeable difference to reducing heat loss through the bay. It also looks great, and was easy to fit.

Really impressive noise reduction. Fitted mine 150mm away from my existing double glazing with vertical blinds fitted in the gap and what a difference. Hardly able to hear any noise at all. Even pleased the wife!. Good quality and looks great as well. Winner winner........

We have gradually been installing secondary glazing over the past couple of years fom Clearview. Have just installed to a tricky bay window and very pleased with the outcome. All fitted perfectly and advise from Clearview very helpful to make sure I ordered the right size / type of glazing. Noticing the difference already in terms of heat insulation and soundproofing. Would highly recommend the company if considering buying.

I purchased 3 windows. The Clearview website is excellent, allowing instant quotes for different configurations. The videos and support material on the site are great. The communication through the ordering to delivery process was really good, and the windows were delivered to the advised schedule. The windows were great quality and were straightforward to install following the Clearview Instructions. I would certainly buy from them again.

Absolutely fabulous. Took a bit longer to arrive but it was worth it. SO easy to install, only took 30-45 minutes, and after doing the trim and sealing around the sides it’s made SUCH a difference to my bedroom, living in an end terrace on a traffic lighted junction in the city centre was so noisy at rush hour, but the traffic is a normal decibel now. Thanks so much - I’ll be ordering for 2 more of my windows in time. Your glazing has meant I will now not be thinking about moving anytime soon! Thanks!

SLIMLINE SINGLE PANEL UNITOur front bedroom ground floor noise levels have gone from horrendous, distracting road noise to hardly a whisper after purchasing a secondary unit. The busy road is 3m away!The company talked me through the measuring process and specifications for what was a complicated space to work with, with an unusual original frame and lack of space for fixing due to the sash windows taking up a lot of the frame depth.The unit fitted perfectly and was exactly as expected in terms of weight and fixing. The noise reduction was better than I imagined. An added bonus is that it is practically invisible! Believe me, the slimline unit is fitted in front of the upvc sash windows in the photos!We now get more noise coming through our composite front door and into the room via the hallway, than through the window!Well worth the price.

Very impressed with Clearview.The online ordering worked perfectly and the chance to double check before the ordere is put into production is a plus.I ordered 8 units for the gound floor of my house including a very large unit for french doors.All were manufactured to millimeter precision and delivered in 4 weeks, on the date specified, by a very helpful/friendly driver.Extremely well packed, the overall quality of the frames and glass is first class.All frames and panes are clearly marked to indicate their positions meaning installation took less than a day.Ground floor complete and I can already notice a reduction in the noise level from an adjacent road.I am now awaiting the arrival of a further 9 units later this month, for the first floor, to finish the job.

I recently ordered a sash secondary window which I wanted to fit myself. A short time after I placed the order I received email confirmation of the order, but also with a drawing/specification of how the window would look, just to confirm sizes etc before they started making it. I was kept up to date throughout via email, and when the delivery date was set the window turned up on the arranged day, perfectly packaged with no issues whatsoever. Along with a totally realistic and fair price I would have no reservations in recommending them. Perfect service.

A fantastic product. I phoned Clearview for technical advice before ordering and they couldn't have been more helpful. The online price calculator is simple to use and the installation instructions were clear and concise. The unit was well packaged and very easy to install. Looks smart, blends well with the existing window and reduces road noise.

12:18 11 May 21

I was somewhat dubious about secondary glazing, but after several emails back and forth with Andrew, who gave us alot of prompt advice, we took the plunge and ordered the units to DIY. I finally got round to fitting it last weekend & we’re so pleased with it-it was very easy to install & looks great! Much better than we thought it would look! The units are very sturdy, but don detract from the window. It certainly helps block out noise - we just need the weather to cool down again now to see how effective it is for the warmth, but I'm sure they'll be good as they're so well fitting. All in all, if you have moderate DIY skills, these are very straightforward to install, and look great once in!

This last week I had the secondary glazing delivered 3 weeks afters ordering which is a great turn around. I ordered them to reduce traffic noise living on a busy junction and the affect is immediate and drastic. Barring the loudest motorbikes, lorries and cars the noise has been almost eradicated. I ordered the 6.8mm acoustic panels, overkill? Maybe but I wanted to order the best within my budget and can highly recommend it.One other benefit I wasn't expecting was how much warmer the house is, the double glazing as good as it is still seemed to be letting some cold air through, sliding open the window you can feel the difference in temperature.If you're on the fence about buying secondary glazing, I'd highly recommend from clearview. I worried about the installation and measuring but it all worked out great. I'll be ordering more to finish the house.

Great communication from Clearview and their service team, they double check everything before dispatching your goods to ensure they’re no issues on your side and on theirs and if you’ve any technical questions you want answered that your unsure about, they’re at hand to talk to you personally. The windows came a daily earlier than expected luckily for me I was off and if you’re handy with a cordless drill and level like myself this job can take up to 2/3 hours to do.The windows look great and keep out the wind from my daughters draughty old sash windows.

We are very pleased with our secondary glazing from CLEARVIEW and the service we received. From the very helpful discussions and advice by phone, to the delivery exactly on time of a very high quality product we couldn't have asked for better. All 9 windows fitted exactly and were very easy to install. We plan to order more and can recommend this firm without hesitation.

Found this company after looking more locally on the internet. Excellent and knowledgeable service. Kept fully informed (10 emails overall!). Also they were 50% cheaper than another quote. Easy to follow instructions for choosing correct product (a secondary glazing panel) and measuring to get correct fit. I did phone with a query and spoke to someone very polite and helpful. Product exactly as described. All in all, highly recommended.

I was sceptical as to whether these double glazed window units would live up to all they were supposed to, but yes they have and am now measuring up for more.

11:02 25 Jan 21

Excellent communication during the order process, and when the windows arrived they were very well made, and far more substantial that I expected . The effect of adding the windows was immediate, and they were very easy to fit, following the fitting guide.

Very happy with purchase. Instructions were good. Secondary glazing fits perfectly. Room now warmer & quieter. I will purchase for another window in the New Year

Product specification and ordering was very easy; excellent web site. Delivery was well organised and units well wrapped. Fitting of the units was quite straightforward, except that there were three panes that were far enough out of square to need attention. I managed to square them up after some very careful unscrewing and plastic hammer banging! A couple of others were out of square but not enough to need straightening. The screws provided with the units were hopelessly short. Apart from that, once fitted, we are very pleased with them and they are a good solid product.

Ian Shilling

17:29 18 Dec 20

Detailed information on the website, clear communication throughout and a very good product. Being a cautious person I ordered just one window first to be sure I was happy with the quality. I needn’t have been so cautious and I quickly ordered the six more that I needed. I have no hesitation in recommending this business and their secondary glazing.

I found this company on line after reading reviews and their website I placed a order on line I was impressed with the ease of use and the double checking that the sizes were correct .very pleased with the high quality of the product and well packaged. Not the cheapest but if you want quality you need to pay a fair price.I would reccomend that you will have no problems dealing with this company.

We'll I've been totally ripped off!Not by Clearview but by Anglian after ordering £8k of their 'safe and sound' windows for the front I can honestly say they made little difference to the road noise!I ordered Clearview Windows for the side windows and they totally killed the noise, what a difference. I wish I had've ordered these for the front aswell. They would have been much cheaper and worked much better.Clearview kept me well informed about when the windows would arrive, the measurement and installation guides are very clear and easy to follow that even a numpty like me can fit them and they look great! I mean really solid and well built.I'll definitely recommend this company. First class product that really works and first class service!! A*

I have never fitted secondary glazing before. The company were super helpful and very fast with their responses.I ordered two large secondary glazed windows to fit behind very old wooden windows as our office building is listed.As our building was so old the windows frames were not that square so make sure you check this lots of times before ordering.They both fitted perfectly and you can barley notice they are there.Everyone using the rooms have commented on how much quieter and warmer the rooms are.Excellent service and product.

Gary James

11:39 15 Apr 20

Excellent pre-sales technical advice and general communication throughout. I only placed a small value order for my study window to cut the noise down but was treated as though I was doing the whole house, which I will now do in the future. I'm delighted with the results and have saved a great deal of money compared to a quote from a local supplier. Easy to fit for anyone with reasonable DIY skills. It helps if there are two of you!

I got a quote and dealt with Andrew through out the whole process. I was anxious about the measurement and Andrew helped me and he answered all the questions I had.After he installation there were a some teething issues. Andrew dealt with it and now I am very happy with the secondary glazing. I would 100% recommend this company to anyone. They go above and beyond to give an excellent customer service.

Great company, can’t recommend enough.Telephone help from Deborah & the team was excellent.Windows delivered on scheduled day and all 5 panels were in perfect condition. All measurements were exact.Installation very straight forward. The 5 lift out panels (see photo) took around 5 hours to install which was very quick considering I’d never fitted anything like this before.Loads of on-line guides on their website which explain everything in simple to understand language.ClearView were around £1300 cheaper than a local glazing company quoted for the same spec!Great value, great company!

Great product. Great work. Great people!My wife and I live in an apartment in a Grade 2 listed property in the middle of Sheffield and our main bedroom can get quite cold. After looking for possible solutions to our problem online, we reckoned we should investigate the idea of secondary glazing. We contacted Clearview Secondary Glazing and looked no further. From start to finish, our dealings with them could not have been better! They proved to be a thoroughly professional business, who carry out an all round first class service by not only providing and installing a superb product but also by explaining everything in non-ambiguous terms; keeping the customer informed at every stage; turning up when they say they will and for being, well, just very nice people! Worth every penny! Thank you very much Andrew and Craig (and those behind the scenes we didn't get to meet!)

Bought 2 units for our front bedrooms as we are on a noisy main road. Installed them yesterday and the difference in noise is amazing. I went for the 6.4mm laminated glass and positioned the units on the front of the window sill to give maximum gap.

Juliet Shapiro

Our bedroom overlooks a railway line, so we were primarily looking for acoustic insulation (we’d had secondary glazing in our last home, so knew how effective it was). After some online research, we went with Clearview this time, as their prices are competitive, their online quotation system quick and easy, and – perhaps most importantly – their customer service responsive and helpful. As it happened, here were a couple of glitches (on my part) with measuring and specifying, which Andy at Clearview ironed out for me with no fuss. Once ordered, the product arrived on time, and has proved highly effective at reducing the noise. I actually enjoy watching trains go by in near-silence, and have since ordered a similar unit for our living room, to repeat the experience! I can thoroughly recommend secondary glazing in general, and Clearview in particular.

My client wanted a solution to a problem regarding excessive sound being experienced within a large office complex, whilst having conferences and meetings in a large second-floor room with single glazed aluminium windows on two elevations.During my research, I found Clearview to be knowledgeable and very helpful in solving my client’s problem and alternatives with prices to meet the budget available.I was provided quality support throughout the process.The product was delivered on time, as promised with good protective wrapping.The installation was extremely easy, with quality materials and instructions.Once installed, the difference was amazing and whilst showing the client the finished job, a very large articulated lorry being towed by a similarly large tow truck rolled past the conference room within 3 m. The silence was palpable, the client was over the moon and hopefully impressed enough to want this system throughout this large office complex. Watch this space!Many thanks to the Clearview team for making this such an easy process and special thanks to Lianne and Deborah for putting up with my blond moments during the survey and ordering stage.As a shopfitter/office refurbishment specialist, we provide a service and believe that the client is king and by providing a good service the client will happily use us again. Clearview have the same philosophy, sadly there are too many companies who do not.

Good quality windows, accoustic glass does the job well. We fitted these ourselves, but the website and customer service team make sure you've been informed of everything you need to do to measure correctly and that you've chosen the right options for openings. Not the cheapest, but all in all great service, would recommend to anyone.

If you have an older house with "special" windows which are struggling to cope with our ever changing weather conditions, I recommend that you seriously consider Secondary Glazing.Have a look at Clearview's web site first as it is really helpful, then if you are in any doubt speak to them. The Ladies there are even more helpful.Do not rule out fitting them yourself as the quality of the units supplied is first class. The key to it success is in the measurement of the windows you wish to fit. Measure and then check again. I would recommend trying just one first before embarking on a full scale re-fit as it will give you more confidence in the product.I had a condensation problem in my downstairs cloakroom, so I tackled this first. It looked great and it solved the problem.You get expert help, they keep you up to date on delivery (always on time) and the end product is first class, at a fraction of the cost of new glazing.Highly recommended.GeoffChipping Campden

Hi guys,I recently bought some secondary glazing, which arrived on time, 7.00am, just before i went to work..excellent service,Ive just fitted them to my sash windows...They look great,so easy to fit!! Im over the moon with them, I would certainly recommend these windows to anyone..All you have to do is remember to double check your measurements before ordering,,,I would say 3,- 4,hrs to fit 7 windows, Ne bother !!!!!!Thanx once again,Best regards.Syd Carr....P,S. One double glazing company wanted nearly "double" what you guys charge,,,,

We had a large stone stained glass mullioned window together with a sitting room bay window fitted with secondary glazing by Clearview. The brief was to reduce the heat loss from the two largest windows in the house whilst providing a discrete installation. The equipment supplied for the stone window especially needed to blend with the existing structure making it as unobtrusive as possible.Clearview did it! A stone coloured frame together with horizontal sliding windows for the stained glass and a white frame with vertical opening windows for the sash window bay.All installed with little or no mess, completed within the day.The heat loss is noticeably reduced in the house....a great job, many thanks.
