Hello. A few days ago I was asked by a apartment complex to give them a estimate for powerwashing and painting all the railings on every unit. These are garden style apartments and have upper and lower units on each side. There are railings going up the steps on each side of every building and also on the ground level on each side of every building and they run the entire length of the building from one end to the other. There are spindles about every 2-3 inches and those are being painted as well. Each building is about 250 feet long. That is about 500 feet of railing per side or 1000 feet per building! Spraying them is not possible because of the constant traffic and how close cars are parked so the only option is a brush, roller and a whizzy. I have no clue how to estimate this job or what to charge per foot. Any help will be greatly appreciated.
