Excellent service fitting secondary glazing
Customer Service

From Tommy's first visit when estimating through to Kim's fitting of the windows, and not forgetting Abby and Leanne's office support, Barnet Windows have once again provided excellent service. As they had done work for me before - two external doors and upgrading glass in an existing double-glazed unit - they were my first choice for secondary glazing in a bedroom facing the road. They provided a detailed estimate and answered all my questions on how the window would work, the precise way it would fit onto the existing architrave, etc. The agreed budget and all scheduled dates were met, and they were very helpful when personal circumstances meant I had to reschedule the actual fitting date. Kim did a great job fitting the secondary window, went the extra mile by making improvements to the pre-existing architrave and left everything pleasingly tidy. Finally, the secondary glazing has met my expectations in providing a huge reduction in external noise. I wish I'd had it installed years ago! A big thank you to everyone at Barnet Windows.

This is the third time we have used Barnet Window Company. Every time they do exceptional work and the fitters are all very experienced and knowledgeable. Today is was Sam and Marcin. They were super efficient. In addition to installing the new door, they had to reattach a balcony to the new doors. The workmanship was very good and they made everything watertight, which was a concern of ours as the old doors leaked. The installation was in the attic and they made sure all of the carpet was covered and they cleaned up beautifully after themselves. I cannot praise the company and the workmen highly enough.

I only had a couple of windows fitted with secondary glazing, but the approach of the company was professional from the start. All the staff i dealt with were competent, efficient and friendly. Appointments were kept to punctually and the work was completed without any obstacles. The weather is getting warmer so it may be difficult to test how effective the secondary glazing is until next winter.

Sam, Martin, Chris and Spencer were very professional, friendly and helpful. They were very good with my husband who has dementia and we’re mindful of areas that could be dangerous for him. They always cleared up after each day and when they finished the rooms were spotless. They finished on the date given. We are thrilled to bits with the windows. They look fantastic and our house is warmer. I would highly recommend Barnet Windows to all my friends. Also the office staff were fantastic and helped me out with all my silly queries. Thank you Abbey and Leanne for being so helpful, friendly and patient.

We've used Barnet Windows for all our windows and doors over the past 25 years, and will continue to do so whilst we live in the area. Always great customer service and always go above and beyond where needed. We had our upstairs windows replaced this time - scaffolding set up on Monday and then windows installed Tuesday & Wednesday. The installation team of Sam & Martin were excellent, really friendly and trues cause as less disruption as possible. Left upstairs clean and tidy on both days and did a great job with the installation - exactly what we would expect from Barnet Windows, professional with great customer service.

Barnet Window Company replaced windows in three rooms for us with windows from their Ultimate Heritage range. The Company was impressive from first to last, from the salesman who was our first point of contact to the installers who carried out the work. The works were carried out swiftly and within the promised timescale. The installation was carried out neatly. The installers cleaned up after themselves thoroughly. And the end result was very good. I have no complaints at all and would recommend Barnet Window Company without hesitation.
