How much does house washing cost?
House washing usually means soft washing: cleaner applied at low pressure, then rinsed off. The price depends on how much siding you have. Height and heavy mildew can make the job take longer.

Do it yourself or hire a pro?
Many homeowners wash a one-story house with a garden hose, a soft brush and a siding cleaner. Using a strong pressure washer on siding is risky because it can force water behind the panels or strip paint. For two stories or heavy mildew, a pro is safer.
Common questions
What is soft washing?
It uses cleaning solutions and low pressure to kill mildew and algae, instead of blasting dirt off with high pressure.
How often should I wash my house?
Once a year works for most homes. Humid or shady areas may need it more often.
Is house washing safe for plants?
Pros wet plants before and rinse them after to dilute any cleaner. Ask how they protect your landscaping.
