Professional House Washing in Maryland
Safe soft wash treatment that eliminates mold, mildew, and algae without damaging your home.
About This Service
Your home's exterior is the first thing visitors and neighbors notice — and years of mold, mildew, algae, and grime can make even a well-maintained home look neglected. OneNation Pressure Washing delivers professional house washing services throughout Maryland using low-pressure soft wash technology that cleans deep without damaging your siding, trim, or landscaping.
Unlike traditional high-pressure washing that can strip paint, force water behind siding, and crack mortar joints, our soft wash system uses biodegradable, eco-friendly cleaning solutions that kill algae and mold at the root level. The result is a cleaner home that stays cleaner longer — typically 4 to 6 times longer than pressure washing alone.

A targeted pre-treatment solution is applied to heavy mold, algae, and stain areas to begin breaking them down before the main wash.
Soft Wash Application
Our low-pressure soft wash system applies cleaning solution to the entire exterior, working from top to bottom to ensure full coverage.

A thorough rinse removes all cleaning solution and loosened contaminants. We do a final walkthrough with you to confirm complete satisfaction.

Frequently Asked Questions
Soft washing uses low pressure (similar to a garden hose) combined with professional-grade cleaning solutions to safely clean and sanitize your home's exterior. High-pressure washing can damage vinyl siding, force water behind cladding, and strip caulk. For house exteriors, soft washing is always the preferred method.
