New front door fitted with Ultion smart locking. Fitter, Declan did a fantastic job, professional, courteous and cleaned up after you couldn't ask for any more. Highly recommend GM windows and Doors Ltd.

We had a composite door and 3 windows fitted by GM Windows&Doors and we can't praise them enough. Very reasonably priced and look fantastic. So impressed with the fitters, prompt (got a text to tell us enroute) polite, very tidy and did a great job. I would 100% recommend GM Windows &Doors.

Very pleased. Fitters were a great set of lads who worked their socks off and completed an excellent job, fitting 2 bay windows, 2 smaller windows and replacing 34 glass panels and 2 doors in the Conservatory. They clearly taking pride in their work. Very professional from the first meeting, providing fully itemised quotes, with diagrams, and a copy of the guarantee, so we knew exactly what the cost would be. It was a lot less than we expected. I have no hesitation in recommending G M Windows.

From my initial contact with GM Windows & Doors I appreciated that I was dealing with professional people. On the initial visit George was most helpful in understanding and determining my requirements and suggested solutions. I accepted his advice, and the order was placed. The installation was completed with the utmost care and expertise and the team were very pleasant and courteous and I have no hesitation in recommending them.

Excellent service from start to finish, kept in touch all the time. Friendly staff tided away after each day. Now much quieter with new windows and door. Would highly recommend. Quality products for an great price.

What an amazing company can't recommend highly enough - 5* I was so impressed from start to finish had several quotes and choose George as his quote was very detailed & came across as a very professional company, he also answered all my questions and followed up on any queries I had before starting. Job was booked in and 3 young lads arrived which initially I was apprehensive but what stars they were & their attention to detail & work ethic was amazing. I had a full house of windows fitted and a new door & couldn't recommend this company enough. Very professional and their attention to detail is second to none.

Excellent service. Competitive price. Good communications. First rate products. This is a company that does what it says on the tin. Highly recommended.

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.

George and his team have done an excellent job installing my new French doors. They are very professional throughout the whole process and I would definitely recommend. 5 star service!

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 and the team were excellent from start to finish. From the first site visit, to providing the quote/ contract, to completing the job - all members of the team were professional, friendly, trustworthy and reliable. Not to mention the fantastic job of the windows and doors. They were very respectful, leaving our home tidy every day, and fast without compromising the standard. The attention to detail on the finishing touches also didn't go unnoticed - we can't recommend them enough!

Amazing service. Polite and informative. Super friendly and really professional service from Declan and colleague. Thank you again.

Absolutely a super job well done. Would fully recommend this company. Services Service not listed. More

Really can't say enough good things about this business. but I'll try! Their Google and Facebook reviews are extremely good for a reason. Right from the word go George was super professional, effient and knowledgeable. We wanted bi fold doors and had already had two other companies price for the work, who didn't fill is with much confidence. They also couldn't provide us with tradesmen to undertake the removal of brickwork to create an opening for the doors. Thankfully this was something GM Windows & Doors could do no problem.

The communication from this company is first class and at no point was I left wondering about anything to do with the price, the product or the installation itself. We received a full written and detailed quote with a link to make payment. We agreed a date and the morning of the installation we received a text to let us know that their operative Declan was on his way. Declan and his colleague sheeted everything up to protect our home and worked so hard right until 7pm to make sure everything was to our satisfaction and the area they had been working in was completely cleaned up. The doors themselves are absolutely beautiful and there was not a single thing that I could fault this company on. They are first class. Highly recommended!

Just had an entrance door and some windows fitted by George's team and we are more than happy with the work carried out. The team left the place in an impecable condition after finishing the job and we were surprised to see their high standards. Highly recommended.

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

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.

Excellent, professional service of the highest order. From enquiring to completion of the works GM Windows & Doors were brilliant with great workmanship, quality and value for money and friendly, polite and professional tradesman. I can't recommend them enough. Positive Responsiveness, Punctuality, Quality, Professionalism, Value Services General door installation, Window installation, Glass installation. More

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.
