Totally professional job of replacing our lounge windows in a small apartment block. Communication from start to finish was first class, Bryony, who is a delight to deal with, nothing was too much trouble, liaised with each householder individually and this resulted in a seamless job for all concerned.
The 2 fitters did an excellent job, absolutely no mess at all, in fact you would have never known they had been.
I would certainly recommend G M Windows & Doors Ltd, customer service at its best which is extremely hard to find in this world. Thank you to all concerned.

The installation of three windows was completed quickly and cleanly. The windows look great and fit perfectly. There was no damage to any of the surrounding surfaces. We would not hesitate to recommend GM Windows.

New windows installed with a minimum of disruption. The frames were so well installed that there was no damage to plaster or paintwork. It would be difficult to spot that the windows has just been changed.
The team took care to use dust sheets and to protect all furnishings.

From start to finish, the customer service I received from George and Bryony who, when I was choosing my door, were very patient and helpful, was excellent. I am delighted with my new front door and I would definitely do business with this company again. I would definitely recommend their products.

The workmen came when they said that they would, and worked hard to complete the job to a high standard. All the staff members of this business behaved in a polite professional manner. We have received very positive comments such as, ‘It seems like a really good door, I like how it closes’, also ‘It’s a good quality handle on the door’.

Fantastic company from start to finish. Bryony in the office was so friendly and talked me through the whole process and advised accordingly, always at the end of the phone if I needed more details. The survey was done efficiently and the surveyor advised me regarding alternatives. The fitting was arranged around myself, and Paul and Mick were excellent. They were a great team and did a very professional job consulting me all the way along. I definitely recommend GM Windows.
