Mark and Adrian provided an efficient and great value replacement of my sash window and I’m so happy with the result…highly recommended and his price is great with speedy service and installation. Great communicator too…thanks Mark & Adrian👍👏
Great Service
Great, quick and efficient service. The pricing was right and friendly gents. Done work with them back in 2021 it’s now 2026 and still great service.
Fast and friendly service
Fast and friendly service. Great communication. Would use again. The glass we particularly wanted was more pricey than Mark first thought, but he was very honest and straightforward in his quoting and encouraged us to seek further quotes for comparison. We wanted two broken windows replaced quickly and Mark and Chris got the job done for us within a couple of days of us contacting Mark. Good going considering we phoned on a Sunday. Thanks Mark and Chris!
More than satisfied - Great job!
Mark was quick to respond and able to suit my timetable. The glass I required was non-standard however sourced in a timely manner. Very keen to finish the job to my full satisfaction. Highly recommend!

Mark from London Glazier's service was very fast and efficient. I would definitely recommend.
Outstanding!
Mark offered me an outstanding service. He inspected the requirements, diagnosed the issues with my double glazed windows immediately, and fixed them the very next working day because he has all the supplies in stock. He knows his field, doesn't over-charge, and offers a very professional, swift and friendly service.
Efficient, cost effective, high quality
Very communicative and fair on price. My windows were c.20 years old and in a tired condition but the guys sorted them out and now they’re fully sealed and good as new. Did the job very quickly and were extremely thoughtful and respectful throughout. Highly recommend and I’m happy with the service.
Mark was an absolute lifesaver
Mark was an absolute lifesaver. My very large metal tilt & pivot window broke just two days before Christmas and turned out to be a much bigger job than expected — the entire mechanism had gone.
Mark came out the same day I contacted him to inspect the issue and, importantly, made the window safe so there was no risk of it blowing out four floors to the ground. A couple of days later the window was fully fixed at a very reasonable, fixed price — everything was clearly explained and there were no surprises.
This was a tough job and Mark really knows his windows. After speaking to several other companies, the difference was night and day. Don’t waste your time phoning around other companies — just book Mark.

Amazing job! Super fast and efficient service, a great fix would never be able to tell the difference. On top of a great service, he is such a lovely guy, really made my day with his kindness. Would 100% recommend this service.
Quick
Quick, simple, no nonsense. Sent a picture of the window, they sent a quote back straight away. They suggested I ask around for other quotes too.
In less that a week they came and repaired the issue. No fuss, super polite and friendly. Thank you
