Excellent job

Ace Double Glazing, fitted four new windows and a new door for me, they turned up on time, and did an excellent job, cleared up after they had finished, and took the old windows and door away with them, would not hesitate to use them again.

Excellent job, fair price

Excellent job, fair price, good quality and no BS like some of the other companies. Clean and efficient fitting. Very friendly and helpful at all times. Have recommended to friends and would use again. Went for a peacock blue solidor door and absolutely love the style and quality. Excuse the door surround in pics, as I still need to paint once weather allows. Proper job all round!
