Pressure Washing vs Power Washing in Beaverton and Portland
Power washing heats the water and pressure washing does not. Both use high-pressure water, typically 2,500 to 4,000 PSI on concrete, so the force does the cleaning. For moss and algae neither is the right tool on siding: soft washing under 500 PSI with a cleaning solution kills growth at the root while the water only rinses. Heat earns its place on grease, and almost nowhere else on a house.

Why heat is rarely the answer in Beaverton and Portland
Moss and algae are killed by the cleaning solution and by dwell time, not by force and not by hot water. Heating the water on cladding that needs under 1,500 PSI buys nothing and risks a great deal.
Beaverton is one of the cities listed inside the Clean Water Services municipal stormwater permit area, and that permit allows routine external building wash-down only where no chemicals, soaps, detergents, steam or heated water are used.
Heated or detergent-laden wash water is exactly the category stormwater rules care about. So heat is kept for the job it is good at, grease on a food service pad or drive-through, where the water is contained and has somewhere lawful to go.
Pressure, power or soft wash, surface by surface
The method follows the surface. This is what each common surface gets, and why.
| Surface | Method | Why |
|---|---|---|
| Poured concrete | Unheated, 2,500 to 4,000 PSI | Correct for concrete, sound brick and stone |
| Stamped concrete | Unheated, 1,200 to 2,000 PSI | Full pressure strips the sealer |
| Grease on a food service pad | Heated water | Grease needs heat, and the wash water is contained |
| Vinyl siding | Soft wash, under 500 PSI | High pressure forces water behind panels |
| Fiber cement siding | Soft wash, never over 1,500 PSI | The manufacturer permits a washer only under 1500 psi with wide fan tips, and prefers low-pressure spray |
| Cedar | Soft wash, under 500 PSI | Pressure raises the grain and strips the finish |
| Composition roof | Chemical treatment, rinse under 100 PSI | Pressure strips the granules that protect the shingle |
Three questions to ask before anyone washes your property
Which method on which surface, and why that number. A vague answer means the setting has not been decided, and one setting across a whole property leaves a clean driveway and damage that surfaces months later.
Where the wash water goes. A quote that does not say has not accounted for the part stormwater rules care about.
Whether heat is being used, and on what. On a house the honest answer is usually nowhere.
Booking it

Common questions
Power washing heats the water and pressure washing does not. Both rely on high-pressure water, so the force does the cleaning.
Not in pressure. The difference is the heat, and heat only helps on grease. For moss and algae the cleaning solution and dwell time do the work.
Low pressure under 500 PSI with a cleaning solution that kills moss and algae at the root, while the water only rinses. It is the safe method for vinyl, fiber cement, cedar, stucco and painted wood.
We do not recommend it. Beaverton is inside the Clean Water Services stormwater permit area, which allows routine building wash-down only where no chemicals, soaps, detergents, steam or heated water are used.
