House Washing in St. Petersburg, FL

The exterior of your home is under constant attack in St. Petersburg. Humid air, afternoon downpours, salt off the water, and shade from live oaks give algae and mildew everything they need to spread across stucco, vinyl, and painted block. The result is familiar to anyone who has lived here a while: green shading along the lower walls, black streaks under the eaves, and a dullness that makes even a well-kept home look tired.

St. Pete Lawncare provides professional house washing for homes across St. Petersburg and Pinellas County, including Clearwater, Largo, Pinellas Park, Seminole, Gulfport, and the beach communities. We use soft washing, a low-pressure method that pairs the right cleaning solution with a gentle rinse, so siding, paint, windows, and landscaping stay protected while the growth is eliminated.

What’s Included in Our House Washing

A house wash covers the full exterior of your home, not just the walls visible from the street. Every job includes:

• Pre-inspection of siding condition, loose paint, window seals, and fixtures so we can adjust our approach
• Thorough pre-wetting of all lawn, shrubs, and planting beds around the home
• Soft wash application to all exterior walls, including stucco, vinyl, painted block, wood, Hardie board, and brick
• Cleaning of soffits, fascia, gutter exteriors, downspouts, and eave undersides where black algae collects
• Detailing of shutters, columns, entryways, garage doors, and exposed foundation
• Removal of cobwebs, dirt dauber and wasp nests, and insect debris under eaves
• Complete fresh-water rinse from top to bottom, including exterior windows
• Final landscape rinse and a walk-around with you

Soft Wash vs. Pressure Wash

Concrete can handle high pressure; your house cannot. Pressure washing stucco can chip and pit it, blast water behind vinyl siding, break window seals, and strip paint. Soft washing applies detergent at low pressure, lets it dwell to kill algae and mildew, then rinses gently, so the home is safer and the results last longer.

Why House Washing Matters in St. Petersburg

Florida’s year-round humidity means exterior walls almost never fully dry out, and the summer rainy season from June through September saturates them daily. Green algae takes hold first on shaded walls, typically the north side and anywhere under tree canopy. Black streaking on stucco, soffits, and around windows is usually Gloeocapsa magna, the same organism that streaks roofs, and it feeds on the minerals in the surface itself. Both are living growth, which is why simply hosing them off never works for long.

Local conditions pile on. Homes near the Gulf or Tampa Bay accumulate salt spray that leaves a gritty film and speeds up corrosion on fixtures and screen frames. Oak pollen coats everything each spring, and tannin runoff from oak leaves stains light-colored stucco brown. Irrigation systems on well water spray iron-rich mist onto lower walls and leave orange rust stains that build with every cycle.

There’s a practical side too. HOA compliance letters for exterior staining are common in Pinellas communities, mildew holds moisture against stucco and paint and shortens the life of both, and a clean exterior makes hurricane season inspections easier because cracks and gaps are visible instead of hidden under grime.

Common Problems We Solve

• Green algae shading along lower walls and shaded elevations
• Black streaks and spotting on stucco, soffits, and fascia
• Mildew around windows, under sills, and behind downspouts
• Orange rust staining from irrigation overspray on lower walls
• Brown tannin runoff stains beneath oaks and roof edges
• Salt film and grime on coastal homes
• HOA violation notices for exterior discoloration

Best Time of Year for House Washing

House washing is a year-round service in St. Petersburg, but two windows deliver the most value. Spring, from March through May, clears winter grime and oak pollen and preps the exterior for hurricane season so you can spot needed repairs. It’s also the right time if you’re planning to repaint, since paint should only go on a clean, growth-free surface.

Fall, from October through December, clears the algae bloom that the rainy season leaves behind and gets the home looking sharp for the holidays and the return of seasonal neighbors. Homes with heavy shade or waterfront exposure often benefit from both a spring and fall wash.

What Affects the Cost

Every house wash starts with a free estimate. Pricing depends on:

• Size of the home, measured by square footage and number of stories
• Siding material, since heavily textured stucco or wood requires more dwell time and detailing than smooth vinyl
• Severity of growth, especially thick black algae or long-neglected mildew that may need a second application
• Architectural complexity, including gables, dormers, columns, screened enclosures, and detached structures
• Add-ons like roof soft washing, gutter interior cleaning, or driveway and pool deck cleaning
• Bundling with recurring lawn care service
