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.

We had a very good experience with Barnet Window Company. They were very professional and courteous throughout the whole process. We had bay windows installed at the front of the property and can't be more pleased with the quality and finish. Sam and Marcin, who fitted the windows, did an excellent job and were helpful and polite through the whole process. High recommend this company.

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
