Most single-story homes on the Treasure Coast cost between $225 and $450 for a full exterior wash, while larger two-story or block homes run $450 to $750+. Priced by area, expect roughly $0.15 to $0.40 per square foot of wall surface. The exact number depends on siding type, home size, and how much algae or salt film has built up.
What determines the price of a house wash?
Two houses on the same street can get very different quotes. The biggest factors we see in Vero Beach and Sebastian are:
- Square footage and stories. Second stories need longer reach, ladders, or extended soft-wash poles, which adds labor.
- Siding material. Stucco, vinyl, Hardie board, and painted block each take chemicals differently.
- Severity of growth. Heavy green algae or black streaking on the north-facing wall needs a stronger mix and more dwell time.
- Access. Tight side yards, screened enclosures, and landscaping that must be protected all add time.
Does siding type change the cost?
Yes. Because our team uses soft washing for house exteriors rather than high pressure, the cleaning solution does the work, so material matters more than muscle.
- Vinyl siding is the easiest and usually the cheapest to clean. It rinses freely and shows fast results.
- Stucco is porous and holds algae in its texture, so it needs careful chemical dwell time. It sits mid-range on price.
- Painted concrete block is common on older Florida homes and cleans well, but chalky or failing paint has to be handled gently to avoid stripping.
Why are Florida homes priced differently than up north?
Our humidity, frequent rain, and coastal salt air make Gloeocapsa magma algae and mildew grow fast, especially on shaded and salt-exposed walls. That means Treasure Coast homes often need more product and a proper soft-wash approach, not a quick blast. A cheap $99 pressure-wash special usually skips the algaecide, so the green comes back within weeks.
A fair quote should include the cleaning solution that kills algae at the root, not just a rinse that makes it look clean for a month.
What is usually included?
A complete exterior wash from our crew typically covers siding, eaves and soffits, exterior window frames, and a rinse of the foundation and nearby walkways. Add-ons like the driveway, roof, or gutter brightening are quoted separately. Bundling services often lowers the per-service cost, so ask about combining a house wash with driveway cleaning on the same visit.
How to get an accurate quote
Square footage from a listing gets us close, but a few photos of the dirtiest walls make the estimate exact. We factor in stories, siding, and growth severity before we ever arrive, so there are no surprises on the invoice. Homeowners in Vero Beach and nearby communities can send pictures for a same-day ballpark.
How can you lower the cost of a house wash?
There are honest ways to keep the price down without cutting corners. The biggest is bundling: booking your house, driveway, and roof on one visit spreads setup and travel time across services, so the per-service rate drops. Staying on a regular schedule also helps, because lightly soiled homes wash faster than ones with years of entrenched algae that need extra product and dwell time.
- Bundle services on a single appointment for a combined rate.
- Do not wait years between washes; deep, set-in algae costs more to remove.
- Clear access ahead of time, move cars, patio furniture, and hoses.
- Fix sprinklers that soak the walls, so growth returns slower.
What questions should you ask before booking?
A trustworthy quote is transparent about method and inclusions. Ask whether the company soft washes siding and roofs rather than pressure blasting them, whether the algaecide that kills growth at the root is included, and whether they are licensed and insured. Ask exactly what the price covers, siding only, or eaves, soffits, and window frames too, so you are comparing like for like. A rock-bottom quote that skips the algaecide is not actually cheaper once the green returns in a month and you pay again.
