Amazing service From Alen and his team. His quote beat the competition by far, but without any compromise on the windows. We were only planning to have new wooden double glazed windows for the front of the house, but were actually able to have new windows for the whole house. Alen also made suggestions which we had not thought about. He said we would have beautiful new windows and he has delivered. Clean, polite and kept informed throughout the process. Wholeheartedly recommended.

Had a quote for roof repair which included for 1 missing tile, re fitting existing tiles, repairing flashing and gutter cleaning did not accept quote. On advice from another roofer just had the one missing tile replaced since there was no evidence of any leaks inside the loft or 2nd floor ceilings.
