How much to clean and restore a 350sq metre driveway,it`s nice and tidy with only a bit of rough were the car turns in,dream portfolio job on really posh road so want to be competitive.Already got cleaning job but custy says i can add the restore if price is right.I was thinking 6 tubs of restore at £60 a tin which is £360 and about £900 to clean and roll so around £1200.Would you say 2-3 days work all in tops?thanks Dan.p.s.has anyone ever sprayed one of these or stick to paint brush and roller.
