One damaged window seal, peeling paint or burnt plant bed can cost you a month of profit, and a bad review on top. A simple written pressure washing contract is the cheapest insurance you’ll ever buy. Here’s what to include.
The 9 sections every pressure washing contract needs
- Customer and property details: name, address, phone, email.
- Scope of services: each surface, area and price.
- Schedule and weather: date, arrival window and your right to reschedule for unsafe weather.
- Payment terms: due date, accepted methods, deposit and late fees.
- Customer responsibilities: water access, windows closed, vehicles and furniture moved, pets inside.
- Pre-existing conditions: oxidized paint, loose siding, failed window seals, unsealed outlets, deep stains.
- Plants and landscaping: the precautions you take and the limits of liability.
- Satisfaction window: concerns reported within 48 hours and you’ll make it right.
- Signatures and date from both parties.
Add a liability waiver and property damage release
A separate waiver lists the known risks of pressure and soft washing, records pre-existing damage you observed (with photos), and has the customer acknowledge them before work starts. Pair it with timestamped before photos of every surface.
Common contract mistakes
- Relying on a verbal agreement or a text thread
- Not documenting pre-existing damage
- No deposit on large jobs, leading to no-shows
- Vague scope (“clean the house”) that invites disputes
Note: templates are a starting point, not legal advice. Have a local attorney review your contract for your state.
