How Much Does House Washing Cost? (2026 Guide)
Typical house washing prices
For most homes in our corner of Connecticut, Massachusetts, and Rhode Island, a professional house wash runs $389 to $575. Single-story homes typically start around $389, and two-story homes usually land between $475 and $575 depending on square footage and how much growth is on the siding.
Larger homes, three-story walls, and siding that hasn't been washed in years sit above that range. At Applewood, you get a flat quote up front, usually from a few photos, so the number never changes on wash day.
What affects the price
- Home size and number of stories
- Siding type, vinyl, clapboard, cedar shake, brick, and stucco all wash differently
- How much algae, mildew, or oxidation has built up
- Access, landscaping, and obstacles around the house
- Add-ons like gutter cleaning or exterior window cleaning at the same visit
What a proper house wash includes
A real house wash is a soft wash, not a guy blasting your siding with a pressure wand. The detergent does the work at garden-hose pressure, killing algae and mildew at the root instead of smearing it around. A proper job should include:
- Every side of the house washed, not just the street-facing walls
- Plant-safe detergents with beds and shrubs rinsed before and after
- Soffits, fascia, and gutter faces brightened
- A final rinse that leaves no detergent residue or streaking
If you want the full breakdown of why low pressure matters, we wrote up soft washing vs. pressure washing separately.
How often should you wash your house?
Once a year keeps most New England homes clean. Shaded lots, homes near water, and north-facing walls grow algae faster and may need a wash every 9 to 12 months, while wide-open sunny lots can sometimes stretch to 18 months. The green film comes back faster once it has had a foothold, so regular washes actually get cheaper to maintain.
Why not just DIY it?
A rented pressure washer on vinyl siding is one of the most common ways homeowners put water behind their walls. High pressure forces water through seams and weep holes, and it does nothing to kill the algae underneath. The pro price buys the right detergents, the right pressure, and insurance if anything goes wrong.
