How Much Does House Washing Cost in Martin & Palm Beach County, FL? [2025 Guide]

You've noticed mold, algae, or just general grime on the exterior of your home and you're looking for honest pricing information — not a vague "call for a quote" answer. This guide breaks down exactly what house washing costs in South Florida, what drives the price, and what to watch out for when hiring a company.

House Washing Prices in South Florida — At a Glance

At Pro Exterior, house washing starts at $200. Here's a general range of what homeowners across Martin County, St. Lucie County, and Palm Beach County typically pay:

Small home (under 1,500 sq ft): $200–$300
Medium home (1,500–2,500 sq ft): $275–$425
Large home (2,500–4,000 sq ft): $400–$600
Very large home (4,000+ sq ft): $550–$900+

These are real-world ranges based on typical South Florida homes. Your quote may vary based on the factors we outline below — but we will always give you a firm price before starting any work.

Pro Tip: Get at least 2–3 quotes when hiring a house washing company. If one quote is dramatically lower than the others, ask about their equipment, insurance, and what exactly is included. Low-cost operators often use improper pressure (damaging stucco and paint) or insufficient cleaning solutions that lead to faster regrowth.

What Factors Affect the Cost of House Washing?

1. Home Size

The most significant cost driver. House washing is priced based on the total square footage of exterior wall surface — which includes all four sides of the home, not just the front. A 3,000 sq ft home has considerably more wall surface to clean than a 1,500 sq ft home, even if the floor plans are similar.

2. Stories

Single-story homes are the most straightforward to wash. Two-story homes require additional reach, specialized equipment, and more time — typically adding 15–25% to the cost. Three-story or high-elevation homes require even more specialized equipment and safety measures.

3. Severity of Buildup

A home that hasn't been washed in 5+ years with heavy algae, mold, and oxidation buildup will require a stronger solution concentration and more application/dwell time than a home maintained annually. This is reflected in pricing.

4. Exterior Material

Most South Florida homes have stucco exteriors, which are ideal for soft washing. But some materials require special care:

Painted wood: Requires lower pressure and gentler solutions
Vinyl siding: Soft wash only — very sensitive to pressure
Brick: Can handle more cleaning agent concentration
EIFS/Dryvit: Extremely sensitive — must be handled with care

5. Surrounding Landscaping

Heavily landscaped properties with extensive plants, shrubs, or trees close to the house require more prep time to protect and pre-wet vegetation before applying cleaning solutions. This is included in our pricing but affects time and therefore cost on larger properties.

6. Accessibility

Gated communities, narrow side yards, lots with fences right against the house, or homes on hillsides can affect the time required to safely clean all surfaces.

How Often Should You Wash Your House in South Florida?

For most homes in our service area, we recommend a professional house wash once a year. Homes surrounded by trees, in high-moisture environments, or in shaded areas may benefit from washing every 6–9 months. The South Florida climate — with its heat, rain, and humidity — means biological growth accelerates quickly.

Regular washing also protects your paint and stucco from long-term damage. Mold and algae produce acids that slowly degrade exterior surfaces over time. A $300 annual wash is far cheaper than a $5,000–$15,000 repaint or stucco repair.

House Washing vs. Pressure Washing — Why It Matters for Pricing

Be careful when comparing quotes. Some companies offer "house washing" that's actually pressure washing with high PSI water — which can damage stucco, crack caulking, and force water into your walls.

True house washing (soft washing) uses low pressure and chemical cleaning solutions. It takes more product and expertise — which is reflected in a slightly higher price — but it's the only safe method for stucco, vinyl, and painted exteriors. Always confirm the method before hiring.

Bundling Services — Save Time & Money

Many homeowners save money by bundling multiple services in one visit. Popular combinations in South Florida include:

House washing + window cleaning (our most popular combo)
House washing + pressure washing the driveway and walkways
House washing + gutter cleaning (especially before rainy season)
Full exterior package: house wash + windows + gutters + driveway

Bundling saves on mobilization costs and is typically more economical than scheduling each service separately. Ask about combination pricing when you call.

Most residential house washes take 2–4 hours depending on home size, buildup level, and layout. Larger homes or those with heavy biological growth may take longer. We give you a time estimate when we quote the job.

Not necessarily — as long as we have access to an outdoor water spigot and can walk around the exterior of the property. We'll share before and after photos and confirm completion. We do ask that someone be reachable by phone during the service.

Soft washing removes algae, mold, mildew, dirt, and most organic staining very effectively. Rust stains, deep paint oxidation, or stains embedded in porous stucco may require additional treatment or may not be fully removable by cleaning alone. We'll give you an honest assessment during the estimate.

We recommend waiting at least 48–72 hours after house washing before painting to allow surfaces to fully dry. Professional painters actually prefer a freshly washed surface — it removes loose paint, debris, and biological growth that would otherwise cause poor paint adhesion.
