Great communication and amazing service
Great communication via Bryony throughout - really friendly approach. They had some stained glass custom made for me and I could not be happier with the result! The fitter on the day was really friendly too and kept me informed about what he was doing (the house is old so he had to do some workarounds!). Fantastic service.

Hey Poppy 😁 Thank you so much for taking the time to leave us such a lovely review! 😊 We’re thrilled to hear you’re so pleased with the custom-made stained glass and the finished result.
It’s great to know Bryony kept everything running smoothly and that our fitter made sure you were kept informed throughout the installation, especially with a few challenges from the older property.
We really appreciate your kind words and are so happy you had such a positive experience with us.
Thanks again from everyone at G M Windows & Doors!

This was the second time i have used GM Windows & Doors, and this time they came to install 4 windows upstairs. Lovely, friendly guys were so polite, arrived on time, worked really hard, and tidied up after themselves. The windows look great! It has rained since and i have noticed that the water remains on the OUTSIDE of the house where it BELONGS! ...so, bonus! No more towels on the window ledge for me :)

GM Windows - Professionals at work
Over the last 18 months George and his boys have installed all new PVC windows, external front and rear doors and more recently out came our patio doors along with some brick out work and in went 3 bi-folding doors with integral blinds.
George along with his crew have completely transformed our house, and we cannot thank everyone enough. They are professional, courteous, arrive on time, clean up after themselves, and their finished work is exceptional,
Of course, we cannot forget Bryony for her assistance liaising between George the lads and ourselves, she is a godsend, I am sure she has a lot more things to do but I cannot praise her enough.
We would definitely recommend GM Window & Doors

Great company, great product, great service!
G M Windows & Doors recently removed and replaced my existing dining room window, the entire unit, and I am thoroughly satisfied with all aspects of the service I received. The communication was fantastic; the staff I spoke to were all very polite and friendly - a big shout-out to Bryony, Betty, and George - and communicated with me regularly throughout the various stages of the project. The installation was undertaken by two charming chaps - Jack and Mick - who put in a solid graft and worked diligently, installing my window to a very professional standard in a pleasantly surprising quick time. The install was entirely non-intrusive which meant that I was able to work from home while the install was ongoing with zero delays or issues. Also, the lads really properly cleaned up after themselves, removing all waste materials from the site - you'd never even know that they were there! The quality of the window is also top-tier! Very solid. Very impressed. All in all; great company, great product, great service.
