Got quotes from elsewhere and went with Barnet Window Company. Not the cheapest, not the most expensive but the service, communications with changes handled and the fitting by Kim was exceptional. Very pleased with the product quality, look and fit and so are my neighbours. Impressive.

I had internal doors fitted to shut off a very old conservatory. I am very happy - from original call to fitting, which only took a few weeks. Everyone I dealt with were helpful and friendly. The guys on the fitting day were lovely, kept everything clean and explained the doors to me in detail. I’ve used Barnet windows before and will continue to recommend them

I recently had both casement and sash windows installed by Barnet Windows, and I am extremely pleased with the outcome. The new windows have greatly enhanced the appearance of my home, combining elegance with excellent craftsmanship. They are beautifully designed, highly soundproof, and have noticeably improved the warmth and comfort of the house. The entire process was seamless and problem-free, from the initial site visit through to the final installation. Every stage was handled with care, and the team ensured that everything was completed to an excellent standard. I fully endorse Barnet Windows to anyone seeking quality products and outstanding service.

I first used Barnet windows in 2021 to replace sash windows at the front of the house. Four years later, they look as good as new, so I had no hesitation in contacting Tommy when I wanted to replace a small window in my shower room. Service from start to finish was excellent as always. I was kept informed at every stage of the process, and Kim installed the window very quickly with no disruption. Would definitely recommend this company.

We recently had our front door and several windows installed by Barnet Window Company, and we couldn’t be happier with the results. From start to finish, the experience was smooth, professional, and stress-free. The team was incredibly helpful during the selection process, offering clear advice and guidance without any pressure. They helped us find styles and finishes that suited our home perfectly. Installation day was just as impressive – the fitters arrived on time, worked efficiently, and left everything spotless once the job was done. The craftsmanship and attention to detail are excellent. The new front door looks fantastic and feels secure, and the windows have made a noticeable difference in warmth and sound insulation. A big thank you to everyone at Barnet Window Company for their excellent service. We’ll definitely be recommending you to friends and family!

From our initial enquiry to the completion of the work, everyone who contacted us or worked on our patio doors was professional, knowledgeable and answered any questions we had. The information provided was thorough and the work was completed as expected. Their confidence in their own team and their products won through. We had our sliding patio doors replaced with smart bi-fold doors. One of the internal vent covers was missing on installation however they pointed it out when showing us how it all works, and have since returned to add the cover. I fully recommend Barnet Window Company.

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.

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.

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.

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
Customer Service

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.
