What our customers are saying

Replacing windows, doors and installing bi-folding


Replaced locking mechanism in double glazed door

“Have used Jon before to replace faulty glazed units in some old double glazed windows, so rang him to see if he could fix jammed kitchen door lock. He arrived the following day as promised, tried hard to fix the faulty mechanism but it needed replacing. He arranged for a new part and returned with it later that same afternoon to replace it. Adjusted door hinges at same time. Told me beforehand what cost would be. He and his colleague are very polite, tidy, arrive when they say or phone if they will be late. Excellent job”
