One star as that was the lowest I could choose. Threatened to have us fined as they claimed we accepted a quote they did not give. Left some of our waste on our neighbours property and claimed that we shortchanged them so demanded a further £20.00 Not to be trusted I'm afraid.

Prompt and very reassuring as I was in a panic. Temp repair within a couple of hours which fully held the torrential rain out. Scaffold arrived next day and the roof fully repaired by the end of the day. They even cleaned my gutter while they were up there! Kept me fully informed throughout, with photos of what they had done, and has rung since to make sure everything is OK in the terrible weather. Would definitely recommend.
