A representative visited, as requested, to give an estimate for replacement windows and doors. He was very polite and knew what he was talking about. He calculated a value for 16 windows, an exterior door and french doors which was very close to what I had in my mind. I decided to go ahead and signed the paperwork and gave a deposit. The following morning I received a phone call from the representative saying he had made a mistake and not included the cost of the french doors. For the french doors an additional sum of money was required or a suggestion of cancelling them. I was not happy so decided to cancel. I thought this was very unprofessional. I now await the surveyor installation.
