soft washing

Done with Care.

Hawaiʻi’s humidity, shade, and salt air allow algae, mold, and mildew to spread quickly across delicate exterior surfaces. Left untreated, that buildup can cause staining, deterioration, and costly damage over time. Big Wave uses professional soft washing to safely remove organic growth before it becomes a bigger problem, helping protect your property and save you thousands in future repairs.

House Washing

A home's exterior collects dirt, algae, and mildew year-round in Hawaii's climate, especially on shaded walls and north-facing siding. We soft wash the entire exterior of your home, restoring its appearance without the risk of damage that high-pressure washing can cause on siding, trim, and paint.

Fences

Oʻahu driveways collect oil stains, tire marks, and algae faster than most mainland climates due to constant humidity and rain. We use high-pressure washing paired with a degreasing solution to lift embedded stains and restore concrete, asphalt, or paver driveways to a like-new finish.

Gutters

Gutters trap dirt, algae, and organic buildup that regular rain doesn't fully rinse away, especially under trees or near roof valleys common on Oʻahu homes. We soft wash gutters and downspouts to clear buildup and staining, helping prevent clogs and improve drainage during heavy rain.

Questions before you book

How often should I soft wash my house in Hawaii

1

Most homes on Oʻahu benefit from a full soft wash once a year, though homes in shaded, humid, or coastal areas may need it more often due to faster mold and algae growth.


What's the difference between pressure washing and soft washing?

2

Pressure washing uses high-pressure water to clean hard, durable surfaces like concrete, asphalt, and pavers. Soft washing uses lower pressure with a cleaning solution and is better suited for delicate surfaces like siding, stucco, and roofs. We offer both, depending on what your project needs.


Is soft washing safe for my home's siding and fences?

3

Yes. Soft washing is specifically designed for surfaces where high pressure risks cracking, warping, or forcing water underneath, making it the safer choice for house exteriors, wood and vinyl fences, and other delicate materials.


How much does soft washing cost on Oʻahu?

4

Cost depends on the size of the area, the surface material, and how much buildup needs to be removed. Big Wave provides a free on-site estimate so you get an accurate price based on your specific property.
