Great quality and competitive price

We had two rotten timber windows replaced in our old Farmhouse. The windows were fitted and they look superb. Great quality and a competitive price.

Superbly finished job

Replaced an outside wooden door with a UPVC one. Initial survey and advice was done very politely and efficiently. I was told demand might cause a wait. Received a phone call offering 8th Jan which I accepted. The fitter arrived on time, worked efficiently, tidied up and left us with a superbly finished job.
