Yes it is. Its designed to look like a hand written note shoved through your door. I was speaking to the neighbour of one of my custys yesterday who'd had a quote from Bens Gutters, they had quoted him £200 for emptying and cleaning the outsides of his gutters on a 2 bed terrace house, with conservatory. Not bad £200 for an hours work!!
i was watching a firm round my way a while back, they must have got a few gutter clearing jobs after they flyered everywhere, £99+VAT.they had 2 ladders and a Platform that fit between the 2 ladders, bit like a scaff tower a the top.well it took em half an hour messing about getting this platform up, and 10mins to do the gutters.
It’s called an estimate; I do it all the time on the phone.
Not entirely a guess.
if you think about it a lot of houses are very similar
