[white] I was wondering if anyone has ever done aluminum siding before. I was asked to give an estimate for a house with aluminum siding and I told her $300. I am not sure what steps to take to do it. Should I just spray it or spray a solution on it first and since it is aluminum what angles would be the best and pressure etc. By the way she thought my price was to high. It was a three bedroom two level house. Also I gave an estimate on a wooden fence and I gave her the same price as I would for a deck which is $1.50 square foot. to clean and seal. she thought that was WAY to much but the way I see it on a fence you have to do both sides so actually the square footage should have been doubled.
