Soft Washing in Port Huron
In Port Huron, soft washing is the method for walls that stay damp: north walls under the tall trees of Sherman Woods and Palmer, side walls on 40-foot Harrison Pointe lots, and walls facing the St. Clair River. A diluted solution kills the growth first, and a rinse near garden-hose pressure carries it off.
Soft washing in Port Huron starts at $349, with no travel fee and a written, line-by-line quote within 24 hours.

Picture the north wall of a Sherman Woods colonial. The master plan describes tall, mature trees across that neighborhood and along its waterfront, and a north wall under them gets little direct sun. Dew that dries off the south side by mid-morning sits on that wall into the afternoon, and green algae and gray mildew spread a little farther each damp day. In Palmer, where the plan says large, mature trees tower over homes, the same thing happens on more than one side of a house. Moss can start along the bottom course, where splash from the beds keeps the siding wet.
Water is the other source of damp. River Park walls facing the St. Clair River and Ballentine walls facing Lake Huron stand beside open water, as do houses on streets that back onto the Black River. Humid air off the water slows drying, so those walls can hold dew and rain for more hours each day than a wall that dries in an open breeze. A soft wash answers both with diluted sodium hypochlorite and a surfactant, given several minutes to work, so the growth is dead before any rinse touches it. On a River Park house, the wall toward the river and the street front can need different strengths, and each is set on site.
The mix is set to the surface. Painted clapboard and trim on an Olde Town or Prospect Place house get a weaker mix, vinyl a standard one, and a deeply shaded wall a stronger one. Under the Palmer or Sherman Woods canopy, expect a shaded wall to hold near the short end of the two-to-three-year range, while a sunny wall on the same house lasts longer. There is no travel fee for the 45-minute trip, and our article on why lake homes grow mildew faster covers the waterfront side of the problem.
Soaking the Beds, Then a Slow Dwell
Beds and shrubs along the foundation are soaked first, so their leaves hold water instead of taking up mist. That step matters most where plantings are dense, as in Edison Shores, which the master plan describes as heavily landscaped with shrubbery and flowers. The spray stays low near the beds and on your side of the property line. The solution is mixed for each surface and applied from the ground up to the eaves. It dwells for several minutes while the green turns tan, and it is kept from drying on the wall in sun or wind. The rinse runs top to bottom at low pressure, and the plants get a second soaking at the end.
Why a Shaded Wall Greens Again
The usual mistake on a damp Port Huron wall is pressure with no killing agent. The wall looks clean that afternoon, but living algae stays in the vinyl's texture and in open wood grain, and on a north wall in Palmer the green can be back by the next summer. Pressure also roughens vinyl and opens old paint, which gives new growth more to hold. The opposite mistake is a mix too strong, left to dry in the sun beside foundation plants on a 40-foot lot, where it can scorch the shrubs on both sides of the property line.
When to Book Soft Washing in Port Huron
Soft washing works from about April through November on days without frost. In Port Huron, April or May is the best window: winter growth is easy to see on north walls, and a wash then gets ahead of summer humidity. Walls facing the St. Clair River or Lake Huron can take a single-wall touch-up between full washes, which keeps the worst side in step with the rest of the house.

Soft Washing in Port Huron: FAQs
Does wash water from my house end up in the Black River?
No, it is kept out of the river and the storm drains, and the mix is kept dilute. Port Huron manages stormwater under an EGLE-administered NPDES permit, and its drainage runs to the Black River, the St. Clair River and directly to Lake Huron. On a lot that slopes to the street, ask for the runoff to be kept off the driveway and out of the storm drain at the curb.
Will the rental inspector flag a black porch ceiling?
It can. Port Huron's rental certification checklist lists the porch ceiling along with the deck, handrails, spindles and steps, and a shaded porch ceiling is where gray mildew settles first, since it gets no sun. A soft wash clears the mildew with a weak mix and a gentle rinse that leaves sound paint in place. If paint is peeling under the mildew, you will see it before the inspector does.
Why is the wall facing my neighbor's house the greenest?
Because the house next door shades it. On Harrison Pointe lots 40 to 60 feet wide, or Mansfield lots of about 50, two side walls face each other across a narrow yard, and neither gets much direct sun. Dew and rain sit on them for hours longer than on the front. That side usually needs the stronger mix, and it is the first wall to show green again.
How much does soft washing cost in Port Huron?
A soft wash is priced as a house wash: from $349, with a typical house at $349 to $700. Stories, siding types and how heavy the growth is on the shaded walls set the number. The written quote arrives within 24 hours with each wall and surface on its own line, and there is no travel fee. See our pricing page.
