We had a very Positive experience for our glazing replacement requirements. I was under the impression that a whole house replacement takes a month or so but was shocked to see that it only takes a-few days at most to get all the door and window frames replaced (obviously once the units are made to measure and ready to go) , I could see how easily a project could go sideways in this industry but was happy with the overall product and service provided by Doorwins aluminium window & door company. A quick Thanks for the prompt production, me and my family can now go on holiday with peace of mind with all the new security features provided, recommended company

My wife and I have lived in our Chiswick home for nearly 18 years, and in all that time, we never felt the need to replace a single door or window. Its a lovely area with kind Neighbours, and we've always felt quite settled. However, some of those
Neighbours recently expressed concern about the condition of our old frames and glass, pointing out how easily someone could gain access through the entryways and this gave us the push we needed to update everything, we decided to replace all the doors, windows, and frames throughout the house. I must say, the new aluminium profiles are very well made and feel incredibly secure. The multi-locking systems and the steel front door weve installed not only add peace of mind but look rather smart as well. Frankly, I doubt even a chainsaw could get through that front door, and that helps me sleep better at night. Times are changing in London, and we must change with them, especially when it comes to security. If you're looking to upgrade or replace your units, Id say this is a trusted supplier you can rely on.

I was given the task of finding a reliable direct supplier for our companys development in North London. After some research and back and forth, I came across Doorwins Aluminium Windows and Doors Group. They had no issue handling our bespoke triangular window requirements, and after the final measure, their quote came in lower than some of the well-known TV-advertised firms. Our contractors are pleased with the profile and overall quality of the products supplied, and well definitely be using Doorwins again very soon. The whole process was swift and efficient with no time-wasting like you often get with smaller showroom based companies.

I remember watching doorwins supply & install all the glazing at my sisters place while she was away on holiday, and I was house-sitting for her. That was two years ago, and I said to myself then when its time to do mine, its definitely going to be through Doorwins. They werent pushy at all, which I really appreciated. I simply emailed over my measurements, got a quote, agreed on everything, and they then came to take final measurements and adjusted the quote to match the exact specs. After paying the deposit, they got started on my window and door frames.
Fast forward five weeks, and they've just finished a full-house installation over the past three days. They even stayed an extra day to make sure I was completely happy with every detail before issuing the completion certificate or asking for the final payment.
My advice? Save yourself time and just send them an email with your sizes, the opening style, colour of the frames, and exact brick-to-brick measurements. If you have any bespoke requirements, include those too. Honestly, its as simple as that.

Our kind words were way overdue, doorwins went above and beyond to help us get exactly what we originally imagined and even surpassed the architectural plans to make the imagination a reality, a very talented bunch and would recommended manufacturer for bespoke residential frames. Im happy to mention that we were promised modern triangular frames that would be unique and thats exactly what was delivered, the home looks great and ready to move into but from the bottom of my heart a warm Thank you to the whole team, recommended glazing company

Originally a supply only order but after delivery the contractor decided to go with supply and fit options due to the guarantee and warranty that comes with this service when replacing windows or doors when the supplying company provides fitting too. We are happy that they accepted and were willing to change our paperwork after delivery , very thankful for this, Good supplier, bespoke triangular frames were no problem for them and the price with lead time was also competitive compared to other London glazing companies, i would use them again without hesitation and also share the contact with my friend and family in the future

The home just looks transformed and fresh since opting in to replace all the windows back and front with Georgian bar glass and simple casement style opening, I am super gutted that we didnt go with the advice to get the front and back patio doors because they look out of place now, ive sent measurements for all 3 doors today and hoping for modern aluminum security thickness, they look really nice on the site, im back using them again so would definitely recommend this company

Harrow on the hill full house replacement from pvc to aluminum vertical slider frames and a 5 panel bifold for patio area , selection of very strong profiles for brand new and bespoke as per requirement. Very happy with full process and next is the kitchen extension which requires a back patio area and flat roof lights, will be again through doorwins company. I think there has also been some confusion with an American firm named doorwin, that is a different company so do not confuse yourself with the usa company, these guys use all english and British or European profiles. The house feels Very security tight plus , the assigned firm has completed the project a week earlier than promised, one of the trusted companies of greater london and the builder will be using again in a month or so. successful completion

My Company recently tried Doorwins assigned supplier for a large project in the Central London area and were quite happy with the outcome. My boss did mention there were some small hiccups on the project, but ones that were expected when there are six different crews working at the same time. The finished product was the main feature, and everything passed regulations on the first attempt. We will be using them again in the future, including for our smaller residential home builds. A simple email was sent with our schedule, and an itemized invoice quote was returned within a few days. Then they sent someone for an exact measure on all frames before manufacturing anything. The profile is tough and looks sleek , a trusted firm. We will be making long term relationships with Doorwins aluminium

frames in aluminium supply and fit within 6 weeks, my contractor is happy and this also saves us time and money when delivery of product is on time, less labour days and faster completion. I've been involved in developing properties, auction buys, land purchases, building new builds for a few years now with three other partners, and I'm not really one to have the time to leave feedback, but I made an exception for this company. Doorwins went above and beyond to help us complete on time and obtain the necessary certificates to pass building regulations, not just for the windows, doors, and roof lanterns, but for the build itself.
Obviously, a good company will have all the right connections, and Doorwins Group are just that, good team who I will work with again.

44 aluminium frames all delivered on time which include some roof lanterns aswell, the feature items have to be the bifold doors and front security door with side panels, they look so sleek and very efficient for a family home. Doorwins group went above and beyond and the final finished project turned out a lot better than I had imagined it to. Hats off to the team for giving us a great price with excellent service , the Knightsbridge home is next but as for Pinner, the loft features start next and weve already taken prices from the same manufacturer that doorwins assigned, all Fensa certificates and 15 year warranty paperwork has been supplied before the final payment so as a family were very happy and feel a lot safer with all the new security features we have going. One of the The best in london and Trusted direct manufacturers for sure

Good experience overall with fast delivery on our supply-only order for 14 aluminium window frames and 2 door frames. In hindsight, we shouldve also gone with Doorwins for the glazing. We later discovered that many suppliers may offer slightly lower prices, but what they provide often doesn't match the spec on paper. Due to that mistake, we ended up purchasing glass for 6 of the units through Doorwins again. Lesson learned. Its a straightforward process just email them your measurements and details, and a direct manufacturer will send back a quote. Simple and efficient. update from me is they have taken the recent extension of both floors of our home and already delivered in 2 thirds of the promised dates, we are very happy about that and wanted to show gratitude by sharing doorwins with other home owners or property developers

This project came at the perfect time, as we planned to be away whilst all the window frames in our family home were replaced. Although the work started a day later than expected due to access issues on the first day, the team still finished on schedule. While we were on holiday, we entrusted Doorwins with the keys to our home so they could replace all the windows. I was particularly impressed with their thorough cleanup, rather than using a stationary skip, they carefully cleared all the old, rotten frames and rubble themselves, loading everything into their van before leaving. It was reassuring to know that the kids wouldnt be exposed to any dust or debris. The house has been transformed with beautiful new French-style windows framed in aluminum, and it now feels much more secure. Im very happy to recommend Doorwins to anyone looking for a reliable and professional glazing replacement company.

Easily supply and fitted 42 windows and doors for our 2 new build residential homes in Southgate London, my company was in need of a manufacturer that could create the frames and fit them within a month tops. Doorwins group were there to deliver on the dates we required, it was a pretty fast turn around for aluminium frames seeing that in the past they do take 3 times the work than upvc. I have to say that our contractor was very happy with the overall time which saves us on the whole project, whether it be time or money.
I can recommend doorwins from our own professional experience and also use the services provided by them again shortly.
