Totally professional job of replacing 2 large lounge windows

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.

Great service and quality.

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.

Fantastic company to deal with

Fantastic company to deal with. Excellent communication from start to finish. I had a bay window fitted with integral blinds and the result far exceeded my expectations. Paul and Mick arrived on time to fit it and they have done a fantastic job. They are also very nice guys and they cleaned up very well afterwards. Bryony is a little diamond as well. I wholeheartedly recommend this company

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

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.
