GM Windows were outstanding. Quick turnaround with survey and quote, good advice particularly from George, and an excellent installation. I would not use anyone else for doors and windows, highly recommend them.

TRUSTWORTHY & RELIABLE
This is the second time we have used G M Windows & Doors to fit new windows & doors at our home. We would definitely recommend anyone to have G M Windows & Doors to carry out work for them. From start to finish the Office staff and fitters have been trustworthy, reliable, friendly and communicative. We would definitely use G M Windows & Doors again.

Very professional and well mannered fitters would highly recommend

Second time using the company, this time to install the privacy window on the staircase. Really pleased with the effect, Paul and Callum were efficient, tidy, and came right on time, too. The job didn't take long at all, and the window fits perfectly. Very pleased yet again!

Very pleased with the installation of new front door and french door aswell as repairs to a few windows.Turned up on time to give quote and again to do job.Everyone I've dealt with has been excellent.Would highly recommend.

Everything about this job was excellent. From the sales lady Bryony helping us to choose a door that exactly suited our needs to the surveyor who did the measuring to the installation team, everyone we dealt with was friendly, helpful and professional. The finished job was superb and we can't recommend GM windows too highly.

This is the second time we have used GM Windows and Doors Ltd they were brilliant from start to finish. The lads worked incredibly hard and were very polite despite the nightmare job they had to deal with. I would definitely use this company again for any further future projects.

Absolutely brilliant service from start to finish.Many thanks to Callum and Paul for the fantastic job they did replacing our front door and to Bryony, Freya and George for all your help too. Highly recommend this company.

Would highly recommend

First thing to say is that GM responded to our request after one of the larger companies failed to show up. They quickly inspected the windows and measured up before advising us on replacing the glass rather than the whole frame. This saved a considerable amount of money. They were consistently responsive through WhatsApp, always helpful, and though we had to wait a few weeks for the windows to be fitted they were done efficiently and cleanly with no fuss. We also needed some of the hinges and locks sorting and the guys came back to do that at a later date. We received one other quote from a local firm and GM came in at 40% cheaper. Couldn't be happier.

Door and window replacement - great communications from Bryony, super helpful, fantastic quality composite door, super neat job and well fitted. Reliable and responsive.

A great service providing a replacement window to our kitchen. We were kept informed by the team at G M Windows & Doors at each stage of the process. The installation was quick, clean and efficient, with an excellent colour match to
Our other windows. I wouldn’t hesitate to recommend them.

Excellent service from start to finish. The guys who carried out the install were brilliant throughout and left everything clean and tidy after each day. Bryony was also great at keeping me in the loop. Couldnt fault any of them! Would use again if ever I needed to 👍🏼

We couldn’t be happier with the result ! The quality of the door is top - notch sturdy, stylish and has really improved the look of our house. 5* star customer service. From the first consultation to the final installation. The team was professional, friendly and attentive. They answered all our questions, offered helpful suggestions and kept us updated throughout the process. The installation team were punctual , friendly and leaving everything clean and tidy.
Highly recommend this company if you’re looking for quality work and great service 👍 Thank you again.

Done a great job fitting new door and windows to my 220 year old house where nothing is standard size. Very pleased with the work, and would recommend without hesitation.

Absolutely excellent in every way.

This is the third time we have engaged GM Windows and each time we have received an excellent service.
The current task was particularly special as we wanted to replicate the original coloured leaded glass windows in our 1920’s home in a current std, double glazed, window. This was achieved perfectly with the combined efforts of George’s team and Paul from Bolton glass. The process from the initial measurement, pricing, communication and installation were all first class.
Very highly recommend GM Windows.

Another set of super bi-fold doors fitted by George and his team. I can highly recommend this firm. They have a friendly, professional approach and competitive prices. After fitting one set of doors for us last year, I had no hesitation is asking them to return to replace a second set this year. Once again, the team arrived on time, worked professionally with the least disruption possible and left a clean area with new beautiful doors.
