Yes, pressure washing can absolutely damage your home’s paint. Using more than 2,500 PSI breaks down molecular bonds, causing peeling, chipping, and complete paint removal.

Your deck turns gray after winter because UV rays break down lignin, the natural compound that gives wood its color and structural integrity.

That white crusty buildup on your brick walls is efflorescence — mineral salts left behind as water moves through your masonry and evaporates on the surface.

Yes, moss on a brand new roof in Oregon is completely normal—it’s not a sign of poor installation or faulty materials.

Your driveway turns green every spring because Chlorophyta and Cyanobacteria colonies that established themselves in your concrete’s micro-pores during Portland’s wet winter are now reproducing rapidly in the mild spring temperatures.

If you own a home in Portland, you should clean your gutters at least twice a year—once in late fall and again in early spring.

To clean a brick exterior without causing damage, you’ll want to keep pressure between 500 and 1,200 PSI, using a 25-degree nozzle held 12 to 18 inches from the surface.

When pollen and debris coat your solar panels, they create a physical barrier that scatters incoming light and reduces photon conversion rates.

Soft washing combines low-pressure water with biodegradable cleaning solutions to eliminate algae, moss, mold, and mildew from your home’s exterior.

Soft washing uses low-pressure application (below 500 PSI) combined with biodegradable chemical solutions to neutralize contaminants like mold, algae, and dirt at the molecular level.
