The green streaks on your siding aren't just ugly — they're growing.
Algae, mold, and mildew don't sit on the surface — they root into it. High-pressure washing blasts the top layer off and leaves the root behind. Soft washing kills organic growth at the source using low-pressure application and biodegradable solutions, so it stays clean 4x longer. Safe for every exterior surface — siding, roofs, fences, and painted wood.
Right tool. Right surface. Right result.
Pressure Washing
High PSI water to blast away surface grime.
- Best for: concrete, brick, stone, driveways, patios.
- Not for: siding, roofing, painted wood, stucco.
Soft Washing
Low pressure + biodegradable cleaning solution.
- Best for: siding, roofs, fences, painted surfaces, wood.
- Kills organic growth at the root — doesn't just remove it.

How a soft wash works from start to finish.
Protect & Prep
Plants and landscaping pre-wetted. Windows and doors confirmed closed. Surrounding surfaces protected. Solution mixed for the specific material and growth type we're treating.
Apply & Dwell
Low-pressure application coats the surface evenly. The solution dwells to kill algae, mold, and mildew at the cellular level — not just lift it off the surface temporarily.
Rinse & Inspect
A gentle rinse removes the solution and everything it broke down. We walk the exterior with you before leaving — every section inspected, any concerns handled on the spot.
What homeowners ask about soft washing.
How is soft washing different from pressure washing?
Pressure washing uses high PSI water to physically remove surface grime — effective on hard surfaces like concrete but damaging to siding, roofing, and painted wood. Soft washing uses low pressure combined with biodegradable cleaning solutions that kill organic growth at the root. The result lasts significantly longer because the biology causing the discoloration is eliminated, not just blasted off.
Is soft washing safe for my plants and landscaping?
Yes. We pre-wet all plants and landscaping before applying solution and rinse everything thoroughly after. The biodegradable solutions we use break down safely without harming plant life when applied and rinsed correctly.
Can you soft wash a roof without voiding the warranty?
Yes — soft washing is the manufacturer-recommended cleaning method for asphalt shingles. High-pressure washing on a roof voids most shingle warranties and causes granule loss. Low-pressure soft washing cleans effectively without either.
How long do soft washing results last?
Typically 2–4 years on siding and 3–5 years on roofing, depending on the amount of shade, moisture, and tree coverage around the home. Heavily shaded homes may see regrowth sooner — we'll give you an honest estimate based on what we see during the job.
Do I need to be home?
No — soft washing is an exterior service. We just need exterior gates unlocked and all windows and doors confirmed closed before we start. We'll verify this with you when we schedule.
