Free AI-generated pressure washing proposal — PSI specs, soft wash scope, chemical treatments, and per-surface pricing. Customize in 2 min, send as PDF.
Pressure washing looks simple from the outside. Point the wand, pull the trigger, collect the check. But the proposals that win repeat business break down each surface by PSI setting, list chemical pre-treatments by name, and specify what soft washing means vs. high-pressure cleaning. Clients who've had someone etch their concrete or strip paint off their siding with too much pressure will pay more for a contractor who puts the technical details on paper. This template covers residential and commercial exterior cleaning.

Concrete driveway (approx. 900 sq ft): Pre-treat oil spots, pressure wash at 3,200 PSI House siding (2-story, vinyl, approx. 2,400 sq ft): Soft wash with biodegradable mildew treatment at 400-600 PSI Front walkway and front stoop
Driveway: Apply commercial degreaser, agitate with brush, pressure wash with rotating nozzle, rinse. Siding: Apply 3% sodium hypochlorite solution from ground level, dwell 10 minutes, rinse with low pressure. Safe for landscaping.
Driveway: $180 House soft wash: $280 Walkway/stoop: $60 Total: $520
Job takes approximately 2.5 hours. Please have vehicles out of driveway. Close all windows and doors. We'll notify neighbors if runoff will cross the property line.

Create Your Free AccountList the PSI and nozzle type by surface. Concrete can handle 3,000 PSI; cedar siding cannot. Showing surface-specific settings signals you won't destroy their wood deck.
Separate soft washing from pressure washing in the proposal. Algae and mildew on siding need chemical treatment at low pressure — pressure alone won't fix it. Explain the difference.
Note pre-treatment for oil stains. Driveway degreaser applied 20 minutes before washing is the difference between clean and 'tried.' List it as a step.
Include a wet surface warning for decks. Wood should be sealed within 48-72 hours of washing while still slightly porous. If you're not doing the sealing, tell them.
Photo before and after. Not just for portfolio — for dispute prevention. Every job has one unhappy client who claims it 'looked the same.'
Specify water source. Are you using their hose bib or bringing your own water tank? Commercial jobs without an outdoor spigot need this figured out before you show up.
Note landscaping protection. Chemical runoff from soft washing can damage plants. Stating that you'll pre-wet landscaping and cover sensitive plants shows you've thought it through.
Include a 'no guarantees' clause for deep stains. Oil stains over 6 months old, rust, and battery acid marks may not fully come out. Setting expectations in the proposal prevents the 'it didn't work' callback.

Pressure Washing pricing guide →Pressure washing uses high-pressure water (2,000-4,000 PSI) to blast dirt off hard surfaces like concrete and brick. Soft washing uses low pressure (400-800 PSI) with chemical solutions to kill algae, mildew, and mold on softer surfaces like vinyl siding, stucco, and wood. Using pressure wash settings on siding will damage it. A good proposal specifies which method is being used on which surface.
Residential pricing: driveways run $0.15-$0.30/sq ft ($100-$250 for a typical 2-car driveway). House siding soft wash runs $0.20-$0.40/sq ft ($250-$500 for a 2-story home). Decks and patios run $0.25-$0.50/sq ft. Most residential jobs land between $300 and $700. Commercial flatwork (parking lots, loading docks) is priced lower per square foot but higher in total volume.
Not if done correctly. Concrete handles 2,500-3,500 PSI with a 25-degree or surface cleaner nozzle. Damage happens when contractors use a zero-degree nozzle (leaves lines), get too close (etches the surface), or use excessive pressure on stamped or decorative concrete. The proposal should specify the PSI and nozzle for your concrete type.
Siding: once a year in humid climates, every 2-3 years in dry climates. Driveways and walkways: every 1-2 years. Decks: annually before resealing. Commercial storefronts: quarterly or monthly depending on foot traffic. Setting up a recurring schedule in your proposal gets you repeat business at a lower per-visit rate.
Sodium hypochlorite (the active ingredient in most soft wash solutions) will damage plants if applied directly. A responsible contractor pre-wets landscaping, covers sensitive plants, and rinses the area after treatment. The proposal should state what chemical is being used, at what dilution, and what plant protection steps are included. Pets should stay inside during treatment and for 30-60 minutes after rinse.
Not required, but recommended for concrete. Pressure washing opens the pores of the surface, making it ideal for sealer application within 24-48 hours. If you're going to seal, do it right after washing. If the pressure washer offers sealing as an add-on, it's worth considering. For wood decks, sealing within 48-72 hours of washing is strongly recommended to prevent water absorption and UV damage.
