Overview
Decks and fences collect mildew and grime. Cleaning prepares wood for staining.
Wood is easily damaged by high pressure.
What the work usually involves
- Choose method. Low pressure or cleaner.
- The provider does a walk-around. They check for loose siding, open vents and fragile areas first.
- Describe the surfaces. Concrete, siding, wood and roofs each need different pressure and cleaning solutions.
- Water access is needed. Most providers connect to an outdoor spigot.
- Expect plant protection. Good providers pre-wet or cover plants when using cleaning solutions.
Key considerations
- Composite rules. Manufacturers have guidance.
- High pressure can damage surfaces. Siding, wood and roofs usually call for soft washing.
- Staining timing. Wood needs to dry.
- Wood fuzzing. High pressure raises fibers.
- Runoff rules exist. Some cities restrict washing water into storm drains.
- Paint and coatings can lift. Washing can reveal paint that was already failing.
How to prepare your inquiry
- A short description of the job and where it is on the property.
- Your timeline, and whether anything is urgent.
- Rough measurements or quantities, if they matter for the job.
- Any HOA, landlord or property manager rules that apply.
- Your address or nearest cross streets so the request reaches someone local.
When to keep looking
- Pressure to sign or pay the same day.
- Door-to-door offers right after a storm with no local track record.
- No local address or references you can check.
- No written estimate, or an estimate with vague scope.
- Unwilling to share proof of insurance or a license where one is required.
How to vet a provider
- Are you insured if a surface or window is damaged?
- Do you offer sealing after cleaning?
- Do you use soft washing for siding and roofs?
- What cleaning solutions do you use, and are they safe for plants and pets?
- Is the price per square foot or a flat rate?
- How do you handle runoff?
Frequently asked
- When can I stain after cleaning?
- Usually after the wood dries fully.
- How often should I pressure wash?
- Many homeowners clean driveways and siding once a year, but shade, trees and climate can change that.
- Can pressure washing damage my house?
- Yes, if the pressure is too high. That's why many pros soft wash siding and roofs.
