What Siding Washing Methods Safely Clean Green Mold Off Eugene Homes?
We wash vinyl, HardiePlank, and wood siding safely using low-pressure soft washing to remove mold and mildew without trapping water inside your wall framing.
Why Does Green Mold and Mildew Build Up on North-Facing Siding?
Eugene receives high humidity and damp winds, especially near Spencer Butte and College Hill. North-facing walls receive minimal sunlight to dry out moisture. Rain runoff carrying tree pollen and organic dust sticks to siding panels, creating a nutrient-rich environment for mold, mildew, and lichen spores to grow.
How Does Siding Soft Washing Prevent Internal Wall Water Damage?
Blasting siding with high pressure is a major risk. High-pressure wands force water behind vinyl siding through weep holes, trapping moisture inside wall cavities where it causes hidden wood rot and HVAC mold. High pressure can also crack vinyl siding and strip paint off wood. We clean siding using low-pressure soft washing:
- Under 500 PSI: Applied at gentle household garden hose pressure, eliminating water intrusion risks.
- Biodegradable Surfactants: We apply a diluted 1.0–2.0% sodium hypochlorite solution that dissolves mold, mildew, and dirt on contact.
- Safe Rinsing: We rinse siding completely clean, including window frames and glass, leaving a spot-free finish.
How Do We Safely Wash Multi-Story Homes Without Using High-Pressure?
Many contractors climb high ladders with pressure wands, which is extremely dangerous. We wash multi-story Eugene homes safely from the ground using carbon fiber extension poles. Our specialized soft-wash pumps shoot a high-volume, low-pressure cleaning stream up to three stories high, keeping our technicians safe while protecting your home.
