Barnet Window Company replaced a decaying window on the second floor of a Victorian house with a uPVC one. Kim and Josh worked quickly and efficiently and I was pleased with the result. The work required erection of scaffolding and this was also done by BWC’s subcontractors without problems. I was particularly pleased with BWC’s communications throughout the process, unlike many firms they were always clear what they were going to do and when, and did everything on schedule.

I’ve consistently received excellent service from this small, family-run business. From my initial enquiry through to fitting, the team were professional, friendly, and trustworthy. The quality of the products is outstanding, and I was particularly impressed with the care they took in making good and leaving everything spotless once the work was complete. I wouldn’t hesitate to recommend Barnet Window Company Ltd to anyone looking for high-quality windows, doors, and reliable service.

We are very pleased with our new windows. Every effort was taken by the installers, Peter and Josh, to do the very best job! The carpets and furniture were well covered, and everything was left clean and tidy after the job was finished. They are very nice people, and take a great pride in their work. We have used The Barnet Window Company before, and had the same great service, and attention to detail. Would thoroughly recommend them.

Barnet Windows have installed three new items in our house during the last 24 months: two bifold doors and one awning. The latest job was a bifold door in our breakfast room. We're very impressed by their work, which is totally professional and competent, and we've enjoyed the new doors and awnings very much. The technicians are craftsmen and have good social skills, so it was a pleasure to have them in our house. Not cheap, but well worth the money.

Barnet Window Company are the only firm that we go to for windows, doors etc and we have used them many times in the past. This time it was for a new double door porch. As on previous occasions, they were efficient in terms of coming round to assess what we needed and to send on the quote. As always, the paperwork came through with clear explanations of cost, payment and design. Our porch was slightly off kilter in terms of size/space, but they were helpful and clear in what they recommended and made any slight changes they needed to ensure a perfect fit. As ever they came on the agreed date and the workmen were polite, efficient and thoughtful. They also ensured they 'cleaned up' after they had finished. We have no hesitation in recommending them and indeed would go as far as to say - why go anywhere else!

A Wonderful Transformation

The Installer from Barnet Window Company, Kim, arrived promptly and got started straight away on removing my old and tired front door and side window and then preparing the area to accommodate my new Solidor composite front door and new double glazed side window. Dust sheets covered the surrounding area and care was taken throughout the process ensuring that nothing was damaged. A few weeks earlier a surveyor from the company had visited to take measurements so that everything fitted, which it did. Within a couple of hours my new door was on its hinges and I could see that everything was taking shape and already looking good! After that, the new side window was installed with a lovely wooden round window board, spaces were filled with expanding insulation foam and the UPVC trim was added. This was all done over time, not rushed at all with the utmost professionalism by Kim with attention to detail, who took care over lining up the trim and sealing all of the gaps making it look amazing like a new build, improving the area 100% to what it looked like before. On completion, Kim then explained to me how the new lock worked and how to use the key. I am so very pleased with the results and I cannot thank Kim and Barnet Window Company enough for their expertise and professionalism for a wonderful transformation and value for money. I would definitely recommend them to anyone who is looking to transform their property, you will not be disappointed.

We asked Tommy to quote for a sliding patio door to replace an existing door and two small windows as we wanted more light. We were pleasantly surprised when he suggested an alternative option which would be less invasive, less expensive and still meet our needs. Once our order was placed we were kept updated by Leanne and Abby in the office. Peter attended promptly to take the measurements and we are delighted with our new door, expertly installed by Kim. We highly recommend Barnet Windows and won’t hesitate to use them again.

This is the third time I have used the Barnet Window Company to replace windows in tenanted property I own in London, which dates back to the early 1900s. As I live in Cambridge I do not get to see the fitters at work but my various tenants have always been very complimentary as to the workmanship. Everyone I have contact with has been helpful and I've never had a problem. I would recommend them to anyone.

We chose Barnet Windows because they offered the best solution to replacing the leaded light front door and side window in our 1920s house. We wanted modern technology and materials but with a traditional look and feel. Barnet went to great lengths to do just that. Their workmanship and attention to detail was great and the actual fitter, Kim, was skilled, talented and knowledgeable. It’s the second door Barnet, and Kim, have fitted for us. Would recommend and use again. Not the cheapest on the block but definitely get what you pay for.

We truly appreciate your continued trust in our team and your recognition that quality and care are at the heart of what we do.

Sam Richards and Marcin from Barnet Windows were wonderful when they visited to remove brickwork from my back wall on the first floor and install a tilt and turn window plus a fixed window. Paul, the company Director, had gone above and beyond to plan a scheme to my specifications so I will be able to get out onto the flat roof at the back of the house to carry out maintenance. He also included a cat flap in the window so my elderly cat 🐈‍⬛ can get outside to sun-bathe. Sam and Marcin the technicians were punctual, polite and very competent at what they were doing. They explained the procedure as they went along, took care to cover my belongings with dust sheets and let me know when they would be doing noisy drilling so I could warn my neighbours. I am extremely satisfied with the work they have completed for me, the installation looks great inside and outside, it is so much safer for me to get onto the flat roof without having to use a ladder and the room is so much brighter now. Having used this company 3 times now I would thoroughly recommend them, their work and the quality of their products and services. Thank you to everyone at Barnet Windows. Kate

I found Barnet Window Company's website and used it to experiment with door ideas to get a rough idea of costs, but then decided to get them to come and discuss ideas with us and am very glad I did. Tommy did the initial visit and talked us through our options very clearly. We were happy with the quote given and every other step from here on was also extremely smooth and professional. Kim did the installation beautifully and when a minor scratch was spotted on the glass a replacement pane was quickly made and fitted. It was a rare pleasure to deal with a company that takes such pride in providing quality products and services, and I'll certainly be using them again for our next door.
