Soft Washing in Clay Township
Every lot in The Colony was laid out on the river or a canal, and the plats off Anchor Bay Dr and St. John Dr put still water a few steps from the back wall. Soft washing kills the algae with a measured solution at low pressure and keeps the rinse out of that water.
Soft washing in Clay Township starts at $349, with no travel fee and a written, line-by-line quote within 24 hours.

On a canal lot, the green follows the shade and the overnight damp. The plats were dredged out of the marsh, so houses sit on low, flat fill beside still water, and a back wall, a fence or a porch ceiling the sun barely reaches can stay wet from dew well into the morning. Green algae and black mildew settle into the siding texture, the soffits and the vinyl fence along the canal edge. A soft wash reaches each of those spots from the ground and leaves the mix on long enough for the growth to die before any rinse.
The mix is sodium hypochlorite cut with water plus a surfactant that keeps it on the wall long enough to work, made milder for painted trim and older cottage wood and stronger only where growth is heavy. On a seawall lot the canal starts a few steps from the back wall, and the seawall plantings sit between the two. Those plants are soaked with clean water first so they shed overspray, the solution goes on only as strong as each wall needs, and the rinse is kept back from the seawall and out of the canal.
Along M-29, the wall facing Pointe Tremble Rd or Dyke Rd also takes salt spray and slush from passing plows, which dries to a gray road film. In Pearl Beach, on the channel side of the road, that road wall is also the shaded north wall, so it carries road film and green growth together, and the mix is set for both. Soffits and fascia, where mildew sits out of the rain, get the same treatment as the siding below them. Soft washing is priced with house washing, from $349, and you have the written quote within 24 hours of asking.
Checking Each Wall, Then Mixing
Each wall is checked before mixing: what it is made of, the paint condition and how heavy the growth is. Beds and plants along the canal edge are soaked with clean water so they shed overspray. The solution is applied from the bottom up so it does not streak, left to dwell while the algae and mildew die, and rinsed from the top down. Second-story gables are reached from the ground, so no ladder rests against the siding. Plants get a final rinse, and rinse water near the seawall is kept out of the canal and away from the storm drains.
Shaving the Growth Instead of Killing It
The usual failure is treating algae like dirt. Pressure shears off the visible layer, scores the vinyl and leaves living growth in the grain, so a canal-side wall turns green again within months, and the scored surface holds the next film more easily. Too strong a mix is the opposite mistake: it can fade painted trim and burn plants that were never wetted. Rinsing toward the seawall sends the mix straight into canal water a few yards from the neighbors' docks.
When to Book Soft Washing in Clay Township
Soft washing works whenever days stay above freezing, which here means roughly April through November. Spring removes the winter's growth before cottage season and the June hatch, and fall clears summer growth before the house sits damp under snow. Calm mornings suit canal lots best, because a gusty day can carry overspray past the plants that were wetted and onto a neighbor's boat.

Soft Washing in Clay Township: FAQs
Why did the green come back within a year after my house was pressure washed?
Because pressure removed the visible layer and left living growth in the siding texture and seams. On a canal lot in The Colony or along Anchor Bay Dr, the shaded walls stay damp enough for that remainder to spread again within months. A soft wash kills the algae and mildew before the rinse, so regrowth starts from almost nothing instead of from what was left behind.
Can you soft wash near a septic system on Harsens Island?
Yes, with the rinse kept off the drain field. Harsens Island homes rely on septic, and many sit beside the St. Clair Flats State Wildlife Area, so the mix is made only as strong as each wall needs. Plants and beds are soaked with clean water first, and runoff is kept out of the ditches and the channel and well away from the field.
Can you soft wash a manufactured home?
Yes. The township holds a few hundred manufactured homes, and their siding, skirting and roof edges clean well at low pressure. The seams and the skirting are where water can be pushed underneath, so the rinse runs with the panels rather than into the joints, and loose panels are pointed out first. Pricing follows the same published rates, from $349.
How often does a canal-side house need soft washing?
Every two to three years for shaded walls, and less often for walls in full sun. Houses on St. John Dr and in The Colony sit at the shorter end on the side facing their neighbor or a porch roof, where the sun reaches least. Booking in spring before the cottage opens keeps the cycle on the same calendar year after year.
