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.

We required a new front door and made a very good decision to choose GM Windows & Doors to supply and install. Throughout George and his team have been very helpful, friendly and professional. I honestly do not think we could have chosen a better company. Excellent workmanship, attention to detail and cleanliness. Can definitely recommend and will be our first choice for future work.

I had received quotes from a few different company’s, G M Windows & Doors Ltd was reasonably priced and they were by far the most professional and took their time to discuss through all the options explaining everything in detail. I decided to go ahead with G&M because of the professionalism they showed and from their 5 star reviews.Throughout placing the order and installation, there was good communication and updates sent on a regular basis and any questions I had were responded to promptly. (I had a lot of questions but was never made to feel like I was mithering them)I had new front and back doors and all my windows replaced. One window needed a new lintel, and this was all arranged by the company ( I had the option to use my own builder). I decided to use their associated builders. He also was very professional taking videos and photos of everything he had completed.The team were professional and arrived on time each day with a courtesy text before arrival.They worked hard to ensure everything was completed to a high standard.

A fantastic company! So pleased with the new windows, back door and composite front door which I have had fitted.From the first appointment George was extremely knowledgeable and helpful. His attention to detail was second to non.I needed so much advice and he had an endless amount patience answering all of my questions. From recommending the best window design most appropriate for the age of my terrace house right down to the finer detail of choosing a font displaying the house number in the double glazed fanlight above the front door!He has a great team. Ashley and co were all professional, friendly and hard working. Their workmanship was to an extremely high standard.So pleased with all the new windows and doors fitted and highly recommend ⭐️⭐️⭐️⭐️⭐️

I contacted this company as I needed a composite front door, the gentleman, the owner, said he would WhatsApp me, which he did. I sent him everything he needed, address, door details etc and he sent a brochure via WhatsApp. A couple of days later he messaged asking if we had chosen a door, which we had, and he said he would give us a price in a couple of days, nearly two weeks later I'm still waiting. If he's not interested I would prefer him to tell me and not just leave me waiting. ????

Great fast service. Gave quote quickly , ordered and fitted within a few days even with Easter Bank Holiday being in the way. Cheaper than others I tried in the area and window looks great. They sent a text when they were on their way to save staying in all day, and were nice polite lads too. Would definitely recommend and will use again in the future ????

It was a very professional service, our fitters Ashley and Ben were the most polite fitters that I have ever come across. Both polite and extremely well mannered! Less fuss, less mess and a brilliant finish. Door was of excellent quality and the team led by owner George is an excellent team, fabulous communication skills and explained everything thoroughly prior to fitting so we knew what to expect. Well done and thank you!

After GM Windows and Doors completed a job next door we were so impressed by the quality of workmanship we decided to go straight to them and did not wish to go anywhere else! George and his team have been fantastic throughout, from quotation stage through to installation we have been kept fully informed of the process. The whole house has been transformed with new anthracite grey double glazed windows, new french doors and replacement composite front and back door. George took the time and effort to source a particular front door that was not normally part of his portfolio. The quality and price were fantastic and the installation team were all polite, friendly and showed attention to detail. The difference in warmth and noise reduction has been unbelievable. I would have no hesitation in recommending GM Windows and Doors to anyone. You won't be disappointed, we are over the moon. Thank you George and Team, a job well done.

I contacted George to replace all our UPVC windows because all of his Which! reviews were 5 stars. He accommodated us despite a very busy order book. At the survey, he and Ashley listened to our needs and provided helpful, friendly advice on the design and colour of the windows, specialist glass etc. They were never pushy. George advised us to get another quote to demonstrate how competitive his prices are. His quote was so competitive, we went for doors as well as windows. The work was undertaken over 3 full week days at scheduled times. The fitters, led by Ashley, were punctual, extremely conscientious and experts at installation. They were also decent, friendly lads, who kept us posted on progress. The finished job is remarkable - the house looks amazing and is much warmer and quieter. The attention to detail on the interior against tile and wall is excellent, George is a perfectionist. He also provided Building Regulations papers and an insurance policy unsolicited. We are delighted and neighbours have been complementary and asked for George's contact details. I would recommend G M Windows & Doors Ltd without hesitation and have complete confidence in this consummately professional business.

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.
