Just quoted a house £25- seemed ok price for me I priced it like this- £2 for each big bay window (4 windows) or two patio doors and 50p small windows. £1 large single windows. Similar house down the road I quoted £25 and he said ok but was £5 more than his previous window cleaner. So thought I did well on that one. But when I went two doors down from the house i just quoted I asked how much people paid in the street and he said £35-40. I messed up !! The guy on the house i just quoted also said if I did insides that would be £50 in total and I nervously agreed. Arent insides more expensive? I guess if the insides take ages I will have to politely tell him I quoted wrongly for them- you can change the price, cant you and up it? It was in a expensive part of Bournemouth and the young guy had a Ferrari in his garage- obviously he was minted!
