Start with net wall area and coats, then add labor for height, scraping, and lead-safe work on older homes. The gallon count is not the price.
800 square feet of exterior wall, minus two doors and six windows, is 687.2 square feet.
2 coats at 350 square feet per gallon is 4 gallons before you add primer or a color change.
Add time for height, masking, and lead-safe prep on a pre-1978 home. Do not hide that time inside the gallon price.
U.S. EPA
Pre-1978 paint work can require lead-safe practices, and that prep belongs on the quote.
OSHA
Exterior and ceiling work often needs fall protection, and that time is part of the labor line.
California CSLB
California's license board states which jobs need a contractor license before you price them.
