I got offered by a guy in an unwritten white van £20 to check and clear the gutters on the house. Only the front really needed doing so I said yes. He didn't have a card or flier.

Anyhow he cleared the gutter but said that some of the concrete in the valley of the gable was insecure and removed it.

Now they're keen to come and do major works on the valley. Now call me suspicious but unwritten van, call from withheld number, no business card, a call this morning from a mobile number that doesn't trace to a bone-fide business in the area and I'm suspicious of being scammed so I've asked for a written estimate. What's the betting I don't get one?
