Barnet Windows make sure at the planning stage that any requirements the customer has are listened to. I live in an old house and the always try to leave as much of the characterful details as possible. The installation service is fantastic. The fitter, Kim Morris came across an unexpected problem during the work , but solved it and made the finished job great

Such nice window installers, polite & efficient - and it rained buckets all day. But they cleaned up as they went along and finished work on time, entirely to our satisfaction. Always have to say BARNET WINDOWS are highly recommended. The quote was accurate/they were polite/ they were tidy - no issues!

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.

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.
