Why Portland Homes Need Professional House Washing
Portland's constant rain and humidity create perfect conditions for organic growth on your home's exterior. What starts as minor discoloration quickly becomes thick moss, mildew, and algae that damages siding and decreases property value.
Why Regular House Washing Matters
Protect Your Siding
Moss and mildew literally eat away at your siding material. Left untreated, you'll face expensive siding replacement years earlier than necessary.
Increase Home Value
A clean exterior can increase your home's value by 5-10%. Essential before selling, but also protects your investment long-term.
Prevent Interior Damage
Exterior mold and mildew can migrate inside your walls, causing health issues and interior damage
Boost Curb Appeal
Professional house washing makes your home look 10-15 years newer. Dramatic transformation in just hours.
Our House Washing Process
Vinyl Siding
Portland's most common siding type. We safely remove green and black streaks, restoring the original color.

Requires gentle approach to avoid damage. We clean without harming wood grain or finish.
Stone and Brick
Removes dirt, mildew, and efflorescence (white deposits often found on brick siding) from masonry without damaging mortar.
Painted Surfaces
Cleans without removing or damaging paint. Gentle enough for older painted homes.
Important: We do not service aluminum-sided houses.
