Exterior Pressure Washing
Surface-matched pressure cleaning that lifts grime without blasting mortar or stripping finishes.
What We Offer
Right pressure for the surface
The most common DIY mistake is too much pressure on the wrong surface. Brick at 3000 PSI blows mortar out of joints; cedar at 3000 PSI gouges the timber. River Valley Contracting matches the pressure to the surface.
Hot-water gas washer with chemical injection. Brick gets a low-pressure soft wash; concrete medium pressure with degreaser; cedar a fine spray with oxygen-based brightener.
Biodegradable agents. Landscaping pre-wetted and rinsed thoroughly before, during and after.

Frequently asked
Common questions
Will pressure washing damage my mortar?
Not at the pressures River Valley Contracting uses. We soft-wash brick under 1000 PSI with chemistry doing the cleaning. DIY damage comes from 3000+ PSI contact.
Can you clean my driveway?
Yes — concrete and exposed-aggregate driveways are routine. Asphalt is rarely worth washing as it weathers naturally; sealcoat is better for asphalt.
Will it harm my plants?
No, when landscaping is pre-wetted and the cleaning agents are biodegradable. We avoid windy days.
How often should I have it done?
Driveways every 2 to 3 years; brick walls every 5 to 7; cedar siding only when visibly soiled (combine with re-stain).
Can you remove graffiti?
Often yes, with specialty graffiti remover plus hot water. Multiple passes may be needed on unsealed brick.
Do you do windows too?
Ground-level windows are included free when on site. Upper-storey by pure-water pole rather than ladder for safety and streak-free finish.
