Chris and Spencer arrived on time worked hard all day and left everything clean and tidy. Chris explained everything I needed to know and showed me how things worked. Thank you all for a great job I am very impressed and have no hesitation about recommending Barnet Windows.

Door and leaded light window fitting in 1920s house

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.

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.

Absolutely thrilled with Barnet Window Company! From start to finish, the service provided by Sam Richards and Marcin was exceptional. They were professional, efficient, and incredibly meticulous in their work. The replacement windows are of outstanding quality, significantly improving the look and feel of my home. The installation process was smooth and hassle-free, with Sam and Marcin demonstrating a high level of expertise and attention to detail. They were punctual, courteous, and kept the work area clean and tidy throughout. Their communication was excellent, keeping me informed at every stage. The windows themselves are beautifully crafted and have made a noticeable difference to the warmth and soundproofing of my property. I couldn't be happier with the end result. If you're looking for reliable, top-quality window replacement, I highly recommend Barnet Window Company. Their dedication to customer satisfaction is truly commendable. 5 stars all the way!

Excellent service fitting secondary glazing

From Tommy's first visit when estimating through to Kim's fitting of the windows, and not forgetting Abby and Leanne's office support, Barnet Windows have once again provided excellent service. As they had done work for me before - two external doors and upgrading glass in an existing double-glazed unit - they were my first choice for secondary glazing in a bedroom facing the road. They provided a detailed estimate and answered all my questions on how the window would work, the precise way it would fit onto the existing architrave, etc. The agreed budget and all scheduled dates were met, and they were very helpful when personal circumstances meant I had to reschedule the actual fitting date. Kim did a great job fitting the secondary window, went the extra mile by making improvements to the pre-existing architrave and left everything pleasingly tidy. Finally, the secondary glazing has met my expectations in providing a huge reduction in external noise. I wish I'd had it installed years ago! A big thank you to everyone at Barnet Windows.

This is the third time we have used Barnet Window Company. Every time they do exceptional work and the fitters are all very experienced and knowledgeable. Today is was Sam and Marcin. They were super efficient. In addition to installing the new door, they had to reattach a balcony to the new doors. The workmanship was very good and they made everything watertight, which was a concern of ours as the old doors leaked. The installation was in the attic and they made sure all of the carpet was covered and they cleaned up beautifully after themselves. I cannot praise the company and the workmen highly enough.

I only had a couple of windows fitted with secondary glazing, but the approach of the company was professional from the start. All the staff i dealt with were competent, efficient and friendly. Appointments were kept to punctually and the work was completed without any obstacles. The weather is getting warmer so it may be difficult to test how effective the secondary glazing is until next winter.
