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.

All the windows at the back were replaced. The work was completed on time and there were no hidden costs. The whole process was very smooth, from the initial enquiry to completion. All the people I delt with were helpful, proffessional, knowledgable and friendly. Communications were dealt with effieicently and promptly. They pride themselves on being a family company providing a reliable and personal service and my expereince with them echos those principles.

A great job from Sam and Marcin installing 6 UPVC windows in my house. Job completed quickly, no mess left at all, highly professional and friendly team. This is the second time I've used the Barnet Window Company and I wouldn't go anywhere else.

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.

Great setvice
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 purchased and had fitted (by Kim ) from Barnet Window Company a new front door to replace our old (27 yrs ) double glazed front door. It all went very smoothly. Again we were very pleased with the overall 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.
