Just had a window fitted in tenanted property. Good communication with George throughout process and fitted within a short period of time from initial enquiry. Tenant very happy - said lads were very professional, friendly and cleaned up after themselves.

Thank you George and the lads for replacing my patio door, it's great and at a really competitive price too. You all worked hard on what was a really cold day and I was impressed at the attention to detail you showed and appreciated you clearing up so carefully afterwards. Thanks very much. Recommended.

Amazing service. Called with an issue with my door in the morning and all fixed by 4pm the same day. Highly recommend and excellent customer service. Fab team.

We are really pleased with the work that George and his team carried out for us. Josh, Jack and Callum arrived on time, carried out the work efficiently and cleaned up thoroughly afterwards. They were really friendly from start to finish. We decided on integral blinds between the glass. Josh explained how to use them and we are very happy with the result. Our rooms look brighter, lighter and airier with no fuss about curtains or external blinds. George gave us a competitive quote too. 5 stars from us. Thank you

Really quick turnaround for a new glass pane in our patio door - from first contact to ordering and fitted within 4 days! Lads were really lovely and polite too. Thanks! Highly recommended.

Excellent job, great communication throughout. Very professional. Great lads who fitted the windows. Very tidy apart from new windows couldn't tell they had been.

Two lads came to do the work and we're excellent to deal with. Not a major job but well priced and was done with the upmost respect to the property

George fit my windows with built in blinds just over 2 years ago. still look great now. He also fitted 4.5m aluminium bi-folding doors with built in blinds again excellent quality.

Top quality work, i used G&M windows and doors to install my doors, they did a great job, that is why i also used them to install my windows as well, professional throughout.

A big thank you to George and his team for a fantastic service from start to finish. We replaced 2 large bays and 2 windows in the rustic profile and we are so happy with them. There was a small issue with a few panes of glass which George fixed straight away and made sure we were totally happy. If you are looking to replace your windows and you'd like the peace of mind that the company will have excellent communication, be there to answer questions, be priced competitively, turn up when they say, take pride in their work, be hard working and have super manners. you have found the one! We highly recommend George and his team and wouldn't hesitate to use them again in the future. Thank you again

George was quick to respond to my enquiry and was able to pop round and provide a quote within a matter of days. He gave us an honest review on the type of door we wanted and his knowledge made us change our minds on what was best. The integral blinds are wonderful. He was happy to fit a new cat flap in the kitchen door and disposed of the old door and window at the end of the job. We are very happy with our new kitchen door and window. We asked George to provide us with a quote for bi-fold doors at the back of the house and will be asking him to do this job sometime in the future.

George responded straight away to my enquiry regarding a replacement window and window hinge repairs. He gave a very reasonable quote and called within a couple of days to measure up. The work was completed just over a week later to a very high standard and much sooner than expected. He was quick, efficient and tidy and I wouldn't hesitate to recommend him to friends and family. Thank you George for a great job.

Having used George and his team to fit windows and doors on another property I had no hesitation in asking him to replace a front door and back door on my own property. Extremely happy with the result and as always a friendly, professional work ethic. Everyone who works there gets on with a quiet professionalism. When I need doors or windows again I will have no hesitation in going straight to G M Windows and doors.

We recently had new windows and door fitted by GM Windows. George was really helpful right from the very start. He was patient and responsive with arranging the quotes with regular communication up to the install date. The attention to detail was exceptional and we were so pleased with the finish product. Very professional and excellent friendly service! I would highly recommend using them to anyone.

We have just had new windows and doors installed and could not be more pleased with the result. The standard of work and attention to detail is superb, which is rare these days. George and the team worked non stop from start to finish and left no mess whatsoever. We would have no hesitation in recommending the company to anyone. Thanks to all the team.

I am very pleased from start to finish. The initial contact for the quote was quick and the price was competitively quoted. George is a very honest person, and extremely helpful, he remained professional at all times. The installation was excellent and the house was left clean and tidy on completion.

After doing research for a company to fit a new front door, I decided to go with George at G M Windows. This was because he was very accommodating and informative, explaining how to design my door, where as other companies I had approached weren't as helpful or didn't return my calls. George fitted my door on the given date within the given time, he was very polite and curtious and his work is to a very high standard. To say the least I am very happy with my door! Thanks George!

Update: had another window fitted by George's team in July 21 and same excellent service. Thanks again GM Windows. I won't be going anywhere else for my windows and doors in future! George and his team were professional and efficient from start to finish. I enquired about a replacement front room window and within a few days George had completed a quote and booked the production of the window on approval of the price quoted.

He kept me up to date with the progress of the production and booked in the fitting as soon as it was ready to install. George and his apprentice did a brilliant job of fitting the window. They arrived promptly on site, ensured carpets were protected and cleaned up leaving an immaculate end result. I've already asked George to quote for more windows! Thank you guys.

Absolutely amazing! I am so pleased with my new windows and doors. From start to finish the team went above and beyond. Boards laid out, everything protected, so respectful. Couldn't thank them enough! What a great company, I would recommend these guys to anyone.

I had been left with a poorly fitted front on a new build house (not their work). George and his team reassured me they would be able to correct it. From start to finish they were amazing could not recommend them enough. Lovely bunch of lads with the knowledge to get the job done. The perfectionism and tidiness was second to none. Thank you!

G M Windows and doors recently installed a rock door at the front and pvc door at the back of my property. I got 3 different quotations for the job and George's price was comfortably the best, he talked me through all the options I had and the benefits that they would bring. The work was completed on time, efficiently and everything was left clean and tidy once the job was complete. The doors work perfectly and I couldn't be happier with the end result thanks lads!

George was initially only replacing one window in our house. However myself and my partner were that impressed with George's and his work colleagues workmanship that we have had a further 3 windows replaced since. They leave your house clean and tidy and nothing is too much trouble, such as designing, measuring and pricing a front door in advance so we have a rough idea of cost, we aim to get the door fitted by George next year.

Some companies would have tried convincing you to purchase there and then but George was relaxed about the situation and provided a price with no questions asked. He isn't half bad at triathlon either.

HIGHLY RECOMMENDED. We have used GM Windows & Doors on two separate occasions now (A new composite front door and for all the windows & doors to a rear extension) and have found the quality of work to be of the highest standard and very competitively priced! George kept us informed at every stage and went out of his way to ensure every little detail was perfect.
