Given Hilo (Big Island)'s hilo averages 130 inches of rain per year — one of the wettest us cities, most homeowners benefit from softwashing at least once a year. Year-round mold and mildew management in Hilo's 130-inch rainfall zone often makes spring or fall the optimal time to schedule service.

Plantation-style homes in Hilo and Puna districts and Off-grid homes in lower Puna — many built without permits historically are the most common home types in Hilo (Big Island) and typically see the most wear. Our local pros are familiar with the exterior materials found across the metro.
How is softwashing different from pressure washing?
Softwashing uses very low water pressure (similar to a garden hose) combined with cleaning agents to kill and remove biological growth. Pressure washing relies on force alone, which can damage surfaces and doesn't kill the organisms causing staining.
Is softwashing safe for my plants and landscaping?
Yes. We pre-wet all landscaping and use biodegradable solutions. We also rinse surrounding areas thoroughly after treatment.
How long do softwash results last?
Softwashing results typically last 2–5 years depending on your climate and shade conditions, significantly longer than pressure washing alone.
Can you softwash a roof?
Absolutely. Softwashing is actually the recommended method for roof cleaning — it removes black algae streaks without voiding roofing warranties or damaging shingles.
