High pressure isn't the answer for every surface. Our soft-wash process uses biodegradable solution to safely remove algae, mold, and buildup from siding, stucco, brick, and roofs — with zero risk of damage.
Soft wash is a low-pressure exterior cleaning method that relies on targeted chemical solution rather than brute force. A biodegradable cleaning agent is applied to surfaces, breaking down organic growth (algae, mold, lichen, pollen) at the root. The solution is then rinsed away — often at pressures lower than a garden hose.

Not sure if soft wash is the right approach? Here's where it excels.
Soft wash is the preferred method for all painted or coated siding. High pressure can get behind panels, crack caulking, and force water into walls. Solution + low pressure cleans thoroughly without any of that risk.
Stucco has a textured surface that traps moisture — pressure washing can push water deep into the wall system and cause serious damage. Soft wash saturates the surface evenly, safely breaking down biological growth.
Asphalt shingles and roof tiles are easily damaged by high pressure. Soft wash clears algae (black streaking), moss, and lichen without dislodging granules or cracking tiles — extending the life of the roof.
Both have a place. Here's how to decide.
| Soft Wash | Pressure Wash | |
|---|---|---|
| Method | Biodegradable solution + low-pressure rinse | High-velocity water stream |
| Pressure | Under 500 psi | 1500–4000 psi |
| Best surfaces | Vinyl, wood, stucco, brick, roofing | Concrete, asphalt, stone, brick pavers |
| Turnaround | Solution dwell time: 10–20 minutes | Immediate results, no dwell needed |
| Typical price range | $250–$600 for residential | $150–$400 for residential |
| Risk if misapplied | Surface staining if not rinsed properly | Surface etching, water intrusion |
