You'll find house cleaning services listed in the Yellow Pages and online at contractor referral services. You may receive a mailer from local companies offering their services, which usually include cleaning siding and decks with a pressure washer. A service will typically charge $872 to clean the exterior of a 1200-square-foot house. You can rent a power washer for $160 a day and do the job and save 82 percent. A popular size power washer is rated 1,200 psi, which means it delivers 1,200 pounds per square inch of water and detergent. The unit has a wand with an adjustable spray nozzle that attaches to a garden hose. In addition to the washer, you need a sturdy ladder long enough to reach the high point of your house, a garden hose and drop cloths to protect the shrubbery. If you have a two-story house, you will probably have to rent scaffolding to safely reach the second floor.
