Got some roof work going on next door? One to watch out for.
Had some guys coming round saying they were from the firm working next door on their roof and that there was work needed on my property on a hair line crack and as the work next door was just finishing and scaffolding was up, it was cheaper to do it now. There also a story that if I didn't sign up for the work, my neighbours wouldn't be able to get a proper guarantee on their property. Luckily my common sense eventually prevailed.
I had half believed them until they seemed nervous about talking to my neighbours and failed to come with a proper written quote and pictures..... They were just after a cash deposit to walk off with.
