So priced a three story house today. Fifteen pvc Georgian style windows and very small conservatory. Very easy access recon half hour to do. I said £25 outside 25 inside. Customer literally shook my hand done he said. Two other quotes he got. One at 40 outside 50 in. The other one. Apparently £200 in and out. I think my price is fair even if it takes a bit longer first clean. What do you guys think?
