Three Upstairs Window Units Replaced
I had six windows and a porch with composite door fitted by Demian. I have been in building most of my life and know a good tradesman when I see one, and Demian is up there with the best. His finish is superb and his always on time. I would highly recommend him to do work for anyone.

Conservatory Glass Pane Replacement
Excellent service. Gave an initial quote, came to measure up, confirmed price, ordered glass, and two weeks later came and fitted it. No fuss. Would more than happily recommend them.
