Huge Thanks for the 68 windows supply for my building firm, Second time weve used this company now and nothing but good things to say , firstly they took their time to make sure everything was manufactured to a high standard with toughened glass and aluminium frames with all building regulations kept in mind. They take the old frames away if there is no skip at no extra cost, clean up was tidy, finishing was also tidy. Would I use them again? I surely would For all London projects

Still some ground work on the new build to finish before ordering the full set of windows and roof lanterns but Doorwins assigned a member of there group to our project pretty fast and someone was taking measurements within a short few days, then hit the delay from our side due to building regulations on our construction project, 6 months later and weve just had our sliding doors put in and which look great. Next we will be wanted to match the windows by replacing the pvc casement style for a sliding window style in aluminium. We did get the best support from doorwins and will be ordering the aluminum windows with a new security residential front door before the next half term so that while we are away, they can supply and fit in our family house in richmond upon thames
Pleasant experience and a company I can recommend to other Londoners

The full aluminium framed roof windows and aluminium sliding doors in all white look really nice, the natural light that it creates is extremely useful in the day and night, sun or moon light it doesnt matter, the extended room just glows naturally. We went for a thicker style frame due to the uk weather, a thicker frame meant stronger standings and glass. The workmanship and service was second to none and very professional, the teams were fast at there tasks and didnt waste any time in getting us a rough price and starting manufacture when we were ready to move ahead, zero pushy sales just one follow up by email. Submit the online form with a number to message on and measurements if you have them, the styles you need and colour of frames, this will save a lot of time and cut to the chase of a final measure if you like the approximate price, I trust doorwins aluminium company after my own experience with them and can share with other home owners in and around London if looking for one of the best suppliers, price and efficiency wise

What i required was a full replacement service provided on 18 windows , a sliding patio door and security front doors. The flat roof glass still need to be delivered as builders havent finished the loft but a pleasant experience so far, professional, with the high quality profiles in both pvc and doorwins main trade aluminium, rehau and cortizo both very very nice to look at and security tight for family homes. Easy to just Send them an email with measurements and Obtain a rough quote , 5 stars from our family and the building contractor team

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.

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

74 frames replaced, we wanted to say a quick thank you for all the great service and help provided on our project and hope to work with you in the very near future. No pushy sales tactics applied and we were never rushed along but rather, everything was done to our schedule and made the whole build a breeze for the team, contractor was extremely happy with doorwins group quality and service , our contractors work closely with manufacturers and suppliers so they would know best. One of the best most Trusted firms in London

Doorwins Aluminium group completed 108 plus aluminum frames with glass completed today. Good experience start to finish, the process was easy and once a rough price had been returned to our office, the speed of everything was incredibly fast , all delivered on time with professional look, if i could give some advice, i would directly email the admin webmail with full specs and measurements and the number of frames required for new builds or replacement or just use the online form and they will assign the best matched supplier manufacturer within their group, the more units the bigger the bulk discount, this is the norm with manufacturers. Our next project will be by the same group which brings me to my advice , always go through doorwins directly as that way you have the people that make things happen in between and making sure everything is above board and smooth as silk, trusted firm

It took just weeks for Doorwins to supply and fit 46 aluminium frames with Georgian glass, mostly side-opening casement windows in anthracite grey. Around this same time last year, we used another company that looks similar to doorwins aluminium but very low grade. Thats why Im genuinely happy to share this positive experience and help raise awareness among London locals about trustworthy companies like Doorwins.
I was very satisfied with the entire process from start to finish and plan to use them again on our next project a small apartment block, roughly twice the size of this one. Were just finalising the details, and its going through Doorwins again.

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.

our company is extremely happy with 80 plus aluminium sliding windows and balcony doors that were a supply and fit service by doorwins manufacturers. The frames are all high quality profile and pass uk building regulations on the first inspection. The actual ordering was easy, sent an email with a schedule to admin team and they returned us a rough quote, on agreement of the price we invited them to take final measurements of 26 newly built apartments, which were available to them on site visit. Once a deposit was secured everything moved swiftly and i was given an update throughout the whole process of manufacture, with choice to change anything beforehand, 6 to 7 weeks was the promised lead time and yesterday was 6 weeks, 3 or 4 frames left but the quality of the product and fit of the frames shows clearly. I will be giving them the next 4 london projects to quote on which some have shaped aluminium triangular frames and roof lights, the flat type, both were on display at the ealing warehouse on uxbridge road. Highly recommended group with a good knowledge of this industry which does make everything so much easier, thank you

I cant believe that 60 windows were supplied in just 3 weeksespecially considering they included bespoke triangular designs and large panoramic aluminium frames. Our experience with other manufacturers has never been as attentive or seamless as it was with the assigned staff at Doorwins. This is a very well-earned and honest few words from me. Im not usually someone who takes the time to write reviews, but the quality, pricing, and advice on this project have been phenomenal from the Doorwins group.
I would use them again in a heartbeat. In fact, Im currently closing another London project, which is definitely going to this direct supplier for manufacturing in West London.
Thanks again, guys.

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.

the group made our project of 60 sliding windows look like a breeze from start to finish, lead times are a lot better from direct manufacturers and prices are always competitively better. I can recommend this company to all my London friends and family or any developers and home owners, we are a development company and doorwins are our new London suppliers for all aluminum and upvc projects, we've trusted them with a mix project that went very smooth so doorwins has proven themselves, send over the measurements via email or online quote form to speed up the process and make it easier or save time.

We had a very positive experience, especially on price as the rough quote for over 86 frames with toughen glass was higher than the actual, weve seen in the past prices rise after actual measurements but a first on the vice versa, cant complain. Doorwins aluminium windows and doors are a group of direct and main manufacturers which helps with lead times and choice, price too as you can see. Overall a positive outcome and our development project of a new apartment block is on par with builders and suppliers thanks to the assigned company who were excellent. Will be using again and Ive paid a deposit for 6 aluminum windows , a 4 track sliding door and flat roof panels for a summer project that we have coming up, in my field its always best to be prepared as projects can move forward or back so its good to have the frames all manufactured and awaiting delivery from the warehouse , on my go ahead. They can assist with pvc or aluminium and its easier to send an email with your schedule including full brick to brick measurements , good north, west london company, next one is ruislip manor , thanks again

We have used them twice for larger projects , I work for a newly registered home developing company and was given the task of acquiring the best service, fabrication and price for 6 new build homes in southgate london area, after speaking to 6 to 7 companies , we decided on the doorwins assigned glazing company for a supply only order. Our builders were meant to take care of fitting but the project was quickly changed to a supply and fit as FENSA was not a requirement on new builds. I have visited the warehouse a couple of times and can vouch for this firm as a trusted window and door supplier , we will be using them again and keeping james in the middle just like the first time, their is no extra cost to keeping doorwins in the picture , good price, good profile and fast manufacturing. The change of mind to fitted was our own mistake but finished product was very good and my manager has given me the role full time to liaise with more companies, meaning more trust, recommended for quote
