I've used Barnet Windows a few times now and they have never disappointed with their service and products. Kim installed the windows and was professional, quick and clean. He explained what he was doing really well, he was funny and I felt safe in his hands. All the staff at the office, from quotes to emails are all professional and timely. I thoroughly recommend using them for any doors and windows.

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.

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!
