Rates checked Oct 2026. Pressure washing costs $0.08 to $0.38 per square foot for house siding according to Angi's 2026 city guides, and $0.15 to $0.50 per square foot for driveways — but almost every pro also sets a minimum job charge of $150 to $250, which changes the math on small jobs. This pressure washing cost calculator takes your surface type, area, stories, and soil level, applies the rate range and the minimum charge, and shows both the raw price and the final estimate. Homeowners use it to sanity-check a quote; operators use it to build one.

A 600 square foot driveway at the default $0.15 to $0.35 per square foot rate comes to $90.00 to $210.00 raw. With the $150 minimum job charge applied, the low end rises to $150 — so the estimate is $150.00 to $210.00. That is why small jobs cost more per square foot than the rate alone suggests.

Surface type, area, stories, soil level, and regional labor costs all move the price — Angi shows a 2,000 square foot house ranging from $240 to $1,200 depending on market. Add-ons like concrete sealing, gutter cleaning, and soft-wash chemicals are quoted separately.
Pros build quotes from square footage internally, but most present a flat project price to the customer. Flat rates quote faster, avoid customer math anxiety, and protect margins as the crew gets quicker. Use per-square-foot math for large uniform commercial flatwork.
Most homes need it every one to two years. Humid, shaded, or coastal areas grow mildew faster and may need annual washing; driveways in tree cover collect tannin stains every season or two.
