Fantastic fitting and aesthetic
Fantastic fitting, the guys attention to detail was faultless and they were so clean. The windows have made a noticeable difference and really look the part. Not soundproof but distinctly better. Very happy.

Outstanding, Highly Recommended
I had my old sash windows replaced by The Soundproof Windows around 6 months ago in my converted Shoreditch warehouse/loft. I am posting this review because it still ranks as the best ever home improvement I have undertaken, and I have had many over 20+ years.
The survey and quotation service is thorough. Installation time is not quick but that is because it is a bespoke product which needs to be made to measure and be transported from whichever country the windows are made, which are of the highest quality I have ever come across.
The quality and craftmanship of the windows and the work that goes into the fitting is simply outstanding. And to top it all off, the customer service is excellent - it's a really friendly and proactive team.
The noise levels have dropped a lot and it is really noticeable. An office building is currently being demolished opposite my flat and the noise is barely noticeable - the product is that good. And my central heating bills have dropped significantly as there are no longer any draughts.
It may not be the cheapest you will find, it may not be the quickest installation you are offered, but by heck these windows feel like they'll last a lifetime. And if you have to pay a little extra and wait a little longer, then you simply cannot go wrong with these guys.
Many thanks to Sebastian and the rest of The Soundproof Windows team

Large noise-reduction windows - highly recommended
I ordered 3 large windows (two were triple glazed, 51db, the other double glazed 46db) from The Soundproof Windows. The initial consultation was very thorough and not at all pushy.
The installation took a little longer than expected to happen, but once the windows arrived they were very quick and professional - the house was left in immaculate condition.
The quality of the product is self-evident - all the fittings are high quality, and the materials excellent. The noise reduction is fantastic - it has made a significant improvement to my sleep since installation a few months ago.
Overall, highly recommended.

Soundproof Windows - Triple glazed imitation sash
I recently had triple glazed imitation sash windows installed at my Victorian terrace house in Battersea for noise and heat insulation. I was very concerned about departing from the traditional sash windows but didn't want to spend a lot of money on expensive double glazed sash windows and still be disturbed by the flight path. The windows perform incredibly well and I no longer get woken up by the first flights coming across London to Heathrow at 5am. The house is also noticeably much warmer and less draughty. Whilst the imitation sash windows do not look exactly the same as traditional sash they are pretty close and much closer than standard casement windows. The trade off definitely works for me.

From quotation to completion
From quotation to completion, a very good service for a quality product. We are on an increasingly busy/noisy road with bay windows to the ground/first floors and a further single sash to the 1st floor front room. We were advised to opt for the triple-glazed sash imitation windows for maximum noise reduction. We did and what a difference. Suffice to say the first floor front room has now become the master bedroom, something that we would never have considered in the past. Ver happy with the result!

Soundproof windows have made a huge difference to my bedroom
The soundproofing of the wall and fitting of new soundproof windows has made a huge difference to my bedroom which faces onto a busy red route.
The fitters did a great job, working over 3 days to fit the soundproofing and windows.

Planes stay out of our home now
Thank you very much.
The windows are really good. Of course we can still hear planes but this is only because we are right under the pathway. At least, we're not waken by them anymore. They are like a whisper.

Good quality and worth doing
The quality of work is great and it has been such a relief to get the soundproofing installed. I can't believe we didn't do it earlier.
The wait time felt a bit long, but on the positive side that meant the windows were prepared to fit precisely and it didn't take long to install.
Would recommend

The team is so professional and really cares about quality. Any small issues were resolved quickly and the end result is STUNNING (and quiet!). On a historical loft conversion, I wouldn't trust anyone else and would definitely recommend this company to anyone. Super job, thank you!

Plane Noise
We live in Clapham North, right under the Heathrow flight path. We acquired our house; a classic Victorian Terraced house. It had the classic PVC double glazed sash windows (10 years old, average quality but not great). Noise level from plane was significant when jumbo jets would fly over, especially at 5.30AM.
We opted for a triple glazed non sash option with different glass thicknesses (high performance, but looking similar), and it has completely solved the problem. We have very large bay windows, so there was a lot of window exposure for sound to come through.
The company is still young, a lot could be improved in terms of communication. However, the windows themselves are great and were delivered on schedule. 5*, cutting them some slack for not always keeping us fully involved.

Great Service and Great Products
I really have to thank Sebastian and the installation team for their fantastic job here.
Originally I was a little skeptical as they’re a new company and have very little feedback online, and additionally the price point isn’t cheap. But when Sebastian came over to conduct the sound survey and talked us through our options, I realised that they really know what they’re doing.
He suggested different products depending upon our budget, and made recommendations based on our noise complaint (mainly from cars going over speed bumps outside our house).
In the end we decided on casement windows with a 43dB glazing, with a total of 10 to be installed. Now this was a big job, but the installation team were extremely efficient and worked hard to cause minimal disruption. In a matter of days all of our old windows were removed and disposed of and replaced with their brand new frames.
The results have been remarkable. I work from home, so I notice it most during the day. Before I would be constantly distracted by what was going on in the street, now I can get my jobs done in peace. And at night we can barely hear anything at all.
The windows themselves look modern and sleek. They shut firmly and are very good quality.
With such a dramatic change to the noise levels in my home, I would highly recommend Soundproof Windows to anyone else suffering from noise pollution.

Excellent - both quality of the product and the service
am very pleased with my new windows and doors - they make a big difference to the levels of airplane noise in the house. Sebastian was very helpful all the way through, both with advice and in practical ways. I am very happy with both the product quality and the level of service I received.

Our new soundproof windows have helped enormously in reducing the sound of passing traffic. Although we can still hear the traffic noise it is less intrusive and we are pleased with the result. The windows are well engineered and the appearance is in keeping with the character of the house which is 170 years old. Sebastian was a delight to deal with.
