4 new build homes with 3 floors each in west london not too far from ealing by isleworth. The aluminium security front doors are heavy duty and cant be knocked in with a riot bar, yes we were pretty lucky to have had a live demonstration, just call it good timing. Windows are a mix of top hung, casements and panoramic with bifold as the patio doors and single pan roof windows with one of them opening. Doorwins were helpful enough to show faults in our drawings and help build a more steady structure which passed first time with building regulations and control. The units are a mix of double and triple glazed and we liked the fact that doorwins being a group meant that we could get everything under one roof, even slight brick work was taken care of for us. I can recommend doorwins uk as a trusted group of direct manufacturers that not only beat prices but have good customer services and faster lead times over many london firms.

8 houses replacement completed, Easy to deal with, doorwins assigned us a firm for our 8 rental properties fast, prices where given within a week for all 8 homes and flats and the price received from main manufacturer with the supply and fit was competitive. Next, were looking to get our family homes windows and doors with roof lanterns replaced to full aluminium profiles. Trusted bunch if companies here and need not to worry , if theirs something they cant supply they will tell your straight up and with myself being an old school brit? I like clarity, recommendation from my family to all londoners looking to replace or buy brand new frames.

The doorwins group manufacturers did an excellent job in supplying white aluminium Casement Georgian bar windows for the entire block, including both casement and bay styles. We initially sent an email with all measurements, dates, styles, and colours, and received a rough quote. Once agreed, a representative visited to take final measurements. Eight weeks later, everything was installed as planned. Our neighbour was supposed to leave a note of thanks on our behalf, but since it's no longer visible, I wanted to leave a few words myself. We're all very happy with the project and how it was managed. Well now be applying for a garden room on the roof, which will require bespoke frames and after some checks the Doorwins Group confirmed it wont be a problem. Looking forward to working with you again soon.

We started with another north london company and After being let down on a sliding patio order and the front of home glazing replacements, we came across Doorwins Aluminium Group. They sent back a quote in no time, followed by a home visit after reviewing our drawings. From there, everything was straightforward. Delivery was uninterrupted completed on time, our builder was impressed with both the profile quality and the toughness of the frames. A recommended and reliable supplier which i can recommend from actual experience

More than 65 aluminium and uPVC frames were delivered today for our latest project just past Ruislip. This marked my first major responsibility at work something my boss entrusted entirely to me. Im genuinely glad we chose Doorwins in the end. Their process was smooth from start to finish, and the range of profiles and styles they offered was outstanding. We had a detailed architectural drawing, which I had a hand in developing, and we stuck to it throughout. Building control signed off without a single issue, and every unit arrived accounted for. Id definitely recommend Doorwins for both residential and development projects. Even though the top floor of our building is designated as office space, they handled it seamlessly. Its clear they can adapt to a wide variety of project types.

32 double glazed window frames and 3 external doorways replaced. Were Putting one of our family homes up for sale, my partner found that aluminium windows and doors do help bring up the value of the home especially when modern secure features are added. The front door looks 8 inches wide but opens like butter with zero tension. Making the home more secure and energy efficient has helped value go up and the replacement was a great decision by my wife and family, its paid for itself basically. Doorwins group is a Family friendly group of manufacturers for , developers, residential home owners, rental properties and Ive even seen portfolio of full new build apartment buildings. Trusted supplier who we emailed all our measurements and were given a rough quote and after assignee attended for final measurements the project moved forward quite quickly , i can recommend to all, just send them your quote via email which was the best way, well, we found it was. I shall share the details of doorwins with friends and family so a well earned review from us

After emailing my measurements and schedule in to admin, a quick drawing of each window and door opening brick to brick, instructions explained by a member of staff, we received the quotes quite quickly , Im sure another person from our office has also uploaded some images of the new build properties that look really nice on finishing. I was Amazed at how new double glazing can change the whole look of a home , recommended after using for our ealing project as a development firm. This company deserves its rating , doorwins group were excellent

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

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

Medium to large new build properties, After a rough quote upon sending measurements and specifications, we ordered the manufacture of windows and doors for a four home renovation project and were impressed by the expert guidance provided, particularly in selecting energy efficient frames that also prioritized security. Doorwins promptly assigned a dedicated bespoke fabricator from their network, accelerating the process swiftly after the initial deposit. The client requested a combination of aluminium and uPVC frames, originally on a supply-only basis. However, our builders later chose to have Doorwins handle the installation as well, a decision that proved wise and brought us complete peace of mind. All frames and glazing were fabricated and delivered on schedule, contributing to a smooth and ultimately profitable project. As a satisfied customer, I wanted to share this feedback to support other homeowners and developers in London looking for a reliable and knowledgeable suppliers

I have had a pleasant experience working with Doorwins after entrusting them with the supply and installation of over 60 aluminium frames for our apartment building in the London Borough of Ealing. The pricing was fair, and the service was impressively fast both in manufacturing and delivery.
Their supply-and-fit service proved to be the best option. Firstly, it ensures FENSA certification for replacement units. Secondly, the frames come with a 15-year warranty. Lastly, the overall cost is noticeably reduced when opting for their all-in-one service, especially through any of the groups companies.
Today, we awarded them a new project involving four residential new-build homes. I wanted to leave a few kind words to acknowledge the helpful guidance and excellent support provided by their staff.
In short, feel confident sending over your request along with your measurements and as much detail as possible. An assignee will be allocated to provide you with a rough quote. Highly recommended firm for both replacement glazing and brand-new installations weve now used them for both.

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.

me and my husband are very happy to leave some kind feedback on a genuinely hard project in Chiswick by Ealing, triangular windows, roof lights , the flat version, security front doors and bifolds with a mix of casement and sliders. The builder had told us to be ready to shop around for at least 2 different manufacturers or direct suppliers and to also keep a supply and fit schedule for all the frames, however, we found everything under one company and saved us so much time and surely afew bucks too. I want to suggest this company to any home owners looking for replacement or brand new frames with good security features as standard grade, aluminum or upvc are both do able, we just ended up emailing over brick to brick measurements of all our frames and a rough price was given before they sent someone to take final sizes and re-quote, deposit paid and full steam ahead, all finished within 4 weeks and that is in season.

Ive had the pleasure of experiencing Doorwins Aluminium Windows and Doors firsthand and would highly recommend them to any homeowners looking to replace all the windows and doors in their house or apartment. The team worked quickly and efficiently, but what stood out most was their flexibility, they worked around our preferred times, including evening appointments, which several local glazing suppliers refused to accommodate. That alone made me feel it was important to share my genuine experience.
From the moment we submitted our initial drawings, the process moved at a smooth and acceptable pace, allowing us to go ahead with our family holiday as planned. I had been considering cancelling the trip due to concerns over leaving the property exposed, but Doorwins delivered on time, removing that worry.
I can confidently vouch for Doorwins as a reliable supplier and installer of quality double glazing. They kept to their promised schedule and delivered exactly what was discussed. Thank you to the entire team.

I asked for the most modern styles in glass and frames that would match a white brick home, doorwins suggested that anthrecite grey in aluminium look really nice on light colour brickwork, they were absolutely spot on and does it look amazing, my husband and I have owned our home for 17 years and thought it be the best time to replace all windows and doors with a modern and more secure profile than the old wood culls and plastic look frames, aluminum just looks and feels so much more secure and also shows through with multiple lock system inner frames. Great advice, great prices and an excellent fast service, what else could us old timers want? Very nice company to deal with

Doorwins assigned an excellent manufacturer to help with a new build that required over 100 aluminum windows and doors over 3 months period. The price was competitive and the profile was pretty high class, apart from price they had given us the best package overall and showed pure professionalism and dedication to complete in promised time. We did have some setbacks from the builders side but everything was worked around quite well, updates regularly given throughout and all doubts were passed through our team before moving to a higher level.
