Transparent Exterior Cleaning Cost Breakdown

Professional Exterior Cleaning Cost Breakdown

House Washing:
Safely removing dirt, pollen, and spiderwebs from your home’s siding typically runs between $300 and $600. For a standard 2,000-square-foot bi-level or colonial home in Mt. Sinai, homeowners usually find the sweet spot right around $450. The final price fluctuates depending on the number of stories, architectural complexity, and the level of organic buildup.

Soft Washing

For delicate surfaces like asphalt shingle roofs, vinyl siding, and cedar shaking, high pressure does more harm than good. Soft washing relies on specialized, eco-friendly cleaning solutions to kill algae and lichen at the root, using water pressure no stronger than a garden hose.

Roof Soft Washing: Typically ranges from $450 to $900, depending on pitch and square footage.
Siding/Delicate Trim: Usually aligns with standard house washing rates but ensures zero risk of material damage.

Residential & Commercial Cleaning Pricing

Residential Pressure Washing:

Hardscape surfaces require the heavy lifting of traditional high-pressure washing combined with professional surface cleaners to eliminate deeply embedded oil, rust, and dirt.

Driveways & Walkways: A standard two-car driveway typically costs $175 to $350.
Decks & Patios: Paver patios, concrete pool decks, or wood/composite decks generally range from $250 to $600 depending on the square footage and whether a post-wash sealing is requested.

Commercial Pressure Washing:
Commercial properties—including local retail storefronts, walkways, dumpster pads, and parking lots—are priced custom-tailored to the scope of work, frequency, and after-hours scheduling needs. Rates generally run from $0.10 to $0.30 per square foot, or are billed on a flat project rate starting at $500 for small storefronts to keep your business pristine and welcoming for Mt. Sinai customers.

Key Factors That Influence Your Estimate

Total Square Footage: Larger surface areas require more materials and time, though the cost per square foot typically drops on larger projects.
Level of Severe Staining: Properties dealing with heavy black algae (Gloeocapsa magma) on the roof or deep oil stains on concrete require specialized treatments that can impact the final investment.
Accessibility: High peaks, steep roof pitches, or tightly spaced properties that restrict equipment setup may require additional safety rigging or time.
