Pressure Washing Cost Calculator

Frequently Asked Questions

How much does pressure washing cost per square foot?

Typical 2025 rates are about $0.15–$0.35 per sq ft for driveways and concrete, $0.20–$0.45 for patios, $0.30–$0.55 for decks, $0.30–$0.60 for house siding, and $0.40–$0.75 for roof soft-washing. Most companies charge a minimum service fee of around $150.

Why is there a minimum service fee?

Travel, equipment setup, and water and chemical costs mean a very small job costs a company nearly as much as a mid-size one, so most pros set a minimum charge of roughly $150 regardless of area.

Can you pressure wash a roof or wood deck?

Not with high pressure. Roofs and wood surfaces require low-pressure soft-washing with cleaning solution. High PSI strips roof granules, gouges wood, and can force water behind siding, causing damage.

How often should I pressure wash my home?

Most homes benefit from an annual wash. Properties in humid climates, heavy shade, or near lots of trees may need cleaning twice a year to control algae, mildew, and grime.

How This Calculator Works

Pressure washing is almost always priced per square foot, with the rate set by the surface type and how much prep, chemicals, and care the job demands. This tool multiplies the area you enter by a 2025 national per-square-foot rate - driveways and concrete are cheapest at roughly $0.15–$0.35, patios $0.20–$0.45, decks $0.30–$0.55, house siding $0.30–$0.60, and roof soft-washing the priciest at $0.40–$0.75 - then applies a pricing-tier multiplier. Because most companies will not roll a truck for less than a minimum, the total is floored at a $150 minimum service fee.

Formula & Method

Per-sq-ft rate = surface rate × tier multiplier. Budget or handyman pricing is ×0.85, standard professional is ×1.00, and premium - insured crews who also seal or use specialized soft-wash chemicals - is ×1.25. Total = area × rate, but never less than the $150 minimum service charge. The result shows the per-square-foot rate plus a low–typical–high total so small jobs that hit the minimum are obvious.

Worked Example

A 600 sq ft concrete driveway at standard pricing: the driveway rate is $0.15–$0.35 (typical ≈$0.25). At 600 sq ft that is $90–$210, typical about $150. Since the low end falls under the $150 minimum, the floor applies and the job lands right around the minimum. A 1,800 sq ft two-story siding wash at $0.30–$0.60 (typical ≈$0.45) runs roughly $540–$1,080, typical near $810.

Common Mistakes

Pressure-washing wood decks and siding - high PSI gouges wood and forces water behind siding; soft-washing is correct for those surfaces.

Power-washing roof shingles - it strips granules and voids warranties; a low-pressure soft wash with cleaning solution is the only safe method.

Forgetting the minimum service fee - tiny jobs cost the same as a mid-size one because of travel and setup time.

Skipping a sealer on concrete - an unsealed driveway re-soils within a year, while a sealer extends results for 2–3 years.

Tips & FAQ

Why is roof cleaning the most expensive? Roofs demand a gentle soft-wash process, safety harnesses, and biocide chemicals to kill algae without damage. Pressure wash vs. soft wash? Hard surfaces like concrete take true pressure washing; siding, decks, and roofs need low-pressure soft washing to avoid damage. Should I bundle services? Combining driveway, walkway, and siding in one visit spreads the minimum fee across more area and lowers the effective rate. How often? Most homes benefit from an annual wash; high-humidity or tree-shaded areas may need it twice a year. This estimate is for budgeting only; on-site quotes account for soiling level and access.
