Cape Cod's climate is hard on exterior surfaces. Salt air blows in year-round, summers bring steady humidity, and north-facing walls rarely dry out between rain events. That combination feeds algae, mildew and the dark bacterial streaks that show up on roofs and siding across Falmouth, Barnstable, Chatham and every town in between. Pressure washing blasts those stains away, but it also drives water behind siding, splits cedar shingles and strips paint faster than it needs to go. Soft washing treats the biology instead of battering the surface: a low-pressure application of a biodegradable cleaning solution reaches into every grain and crevice, kills what is growing there and leaves it clean without the damage.
We mix and apply our solution to match your siding material and the specific growth on your home. Cedar shingles, vinyl, fiber cement, painted wood and brick all respond differently, and what works on one can stain or weaken another. Before we start anything, we wet down your plants and shrubs, close any open vents and walk the perimeter with you. The solution dwells on the surface long enough to do its work, then we rinse at low pressure and do a final walkthrough together. You see the result before we leave, and if anything falls short of what we agreed, we come back and correct it at no charge.

How it works
Our Soft Washing process
01
01
Free On-Site Estimate
We come to your property, look at the siding material, the type and extent of growth, and any areas of concern. You get a clear price before any work starts, with no visit fee.
02
02
Site Prep
We water your plants and landscaping, close nearby vents and windows, and move anything fragile away from the work area. Your property leaves the job in the same condition it arrived.
03
03
Soft Wash Application
We apply a low-pressure cleaning solution mixed for your surface and the specific growth present. It dwells on the surface to kill algae, mildew and bacteria at the root rather than just removing the visible layer.

Rinse and Walkthrough
We rinse at low pressure, re-water your plants and do a full walkthrough with you. If you spot anything that does not meet the standard we agreed on, we fix it before we pack up.
Soft Washing across the Cape
We are based in Falmouth and work in every Cape Cod town, plus Massachusetts, New Hampshire, Vermont, Maine and Rhode Island.
Pressure washing uses high water force to remove surface dirt, which can crack cedar shingles, force water behind siding and strip paint prematurely. Soft washing uses low pressure and a biodegradable cleaning solution to kill algae, mildew and bacteria at the source. The result lasts longer and causes no surface damage.
Most homeowners on the Cape pay somewhere in the range of $300 to $700 for a standard house soft wash, depending on the size of the home, the amount of growth and how accessible the surfaces are. Roof soft washing is typically quoted separately. The only way to get an accurate number for your property is a free estimate, and we can usually respond the same day.
Yes. Cedar shingles are common across Cape Cod and are one of the main reasons we prefer soft washing over pressure washing. High-pressure water splits the grain and shortens the life of the shingles. Our low-pressure approach cleans the surface without opening the wood or pushing moisture behind it.
Most homes in the region benefit from a soft wash every two to three years, though homes near the water or in heavily shaded areas tend to grow algae and mildew faster and may need attention more often. A quick look at your north-facing walls and roof after a wet summer is usually a reliable guide.
Yes. Those dark streaks are almost always caused by Gloeocapsa magma, a type of algae that feeds on the limestone filler in asphalt shingles. It is very common on roofs across Cape Cod. Our soft wash solution kills the organism and removes the staining. We treat the roof at low pressure so the shingles are not disturbed, and the results typically last several years.
