What this calculator estimates
It estimates pressure washing cost from surface type, square footage, material, wash method, stories, access, stain level, chemical treatment, prep, protection, post-wash add-ons, wastewater handling, local labor, travel, and timing.
Why quotes vary
Open driveway flatwork can be fast with a surface cleaner. Two-story siding, roof soft washing, wood decks, oil stains, rust, plant protection, sealing, limited water access, and commercial runoff handling take more time and materials.
Safety note
Planning estimate only. Pressure can damage siding, stucco, wood, roofing, window seals, paint, mortar, and electrical fixtures. Confirm the correct method, PSI, detergents, plant protection, and runoff requirements with a qualified local pro.
How much does pressure washing cost?
Pressure washing cost depends on surface type, square footage, wash method, local minimums, material sensitivity, soil level, stains, height, water access, travel, chemicals, protection, sealing, and service timing.
How is pressure washing priced per square foot?
Many quotes start with a square-foot production rate, then adjust for the surface, method, stains, access, minimum charge, and add-ons. A small job may still hit the company's trip minimum.
Is soft washing different from pressure washing?
Yes. Soft washing uses lower pressure and cleaning solution, often for siding and roofs. It may cost more than a simple driveway surface wash because chemicals, dwell time, protection, and careful rinsing are involved.
Why do oil and rust stains cost more?
Oil, grease, rust, mineral stains, and heavy algae usually need specialty treatment, dwell time, repeat passes, or realistic stain disclaimers. Some stains improve but do not fully disappear.
Should sealing be included in a pressure washing quote?
Sealing is usually a separate add-on for pavers, driveways, decks, or fences. It requires drying time, material, and extra labor, so ask whether the quote includes wash only or wash plus sealer.
Is this a final pressure washing quote?
No. It is a planning estimate for comparing quotes. Actual pricing depends on the provider's minimum, equipment, surface condition, water access, local labor, chemicals, safety steps, weather, and runoff rules.
