Soft Washing in Port Huron Township
Soft washing kills algae, mildew and moss with a diluted solution first, and only then rinses the dead growth off with a gentle, hose-strength stream. In Port Huron Township it matters most on walls that stay damp into the afternoon: north sides on wet soils, walls beside wooded pockets, and homes near the Black River.

On a house along one of the curving platted streets off Beach Rd or Michigan Rd, the bottom course of the north wall is usually the first siding to turn green. Township rules keep downspouts off the sanitary sewer, so roof water empties onto the lawn a few feet from the wall, and every storm splashes soil and water back onto the lowest boards. That strip stays wet the longest. Moss and green algae start there, and gray mildew spreads up the shaded wall above it. The soft-wash mix for that wall is diluted sodium hypochlorite with a surfactant added so it clings to vertical siding through the dwell, and by the time the rinse starts, the growth on the boards is already dead.
Port Huron Township gives that growth a lot of wet hours. The county soil survey rates its main soils as poorly drained, about 4,347 acres of wetland lie mostly south of I-69, and pockets of hardwoods and conifers shade houses across the center and north. One wetland pocket, bounded by Lapeer Rd, Michigan Rd, West Water St and Range Rd, sits close to the residential north half. A shaded wall beside wet ground holds dew well past mid-morning, so it greens over well before a sunny wall on an open lot.
On the larger lots near West Water St and Atkins Rd, a tree line along the back of the yard can keep the rear wall shaded all morning. We mix the solution to the surface and the growth: weaker on painted trim and brick, standard on vinyl, stronger on a heavy north wall. Pricing for a typical house begins at $349, and the 45-minute trip up I-94 carries no fee. For more on the pattern, read why one side stays green.
Waiting for the Green to Turn Tan
Plants get soaked first, since a leaf already full of water takes up little overspray. Each surface gets its own strength of mix, sprayed from the lawn to the eaves, and the crew waits while the green turns tan, usually a matter of minutes. On a wall with moss along the base, the crew lets it work longer and brushes the clumps loose. A low-pressure rinse works down from the eaves, and the crew goes over windows and light fixtures once more so nothing dries on the glass. The plants are soaked again, and downspout outlets are flushed so treated water does not sit in a bed.
Why the Green Comes Back After a Pressure Wash
Blast a green wall with plain water and it looks fine by evening. Living cells stay behind in the texture of the siding, though, and on a damp township lot they rebuild the film by the next wet fall. That pressure also scuffs vinyl and raises wood grain, so the regrowth has a rougher surface to hold. Going the other way, an overly strong mix that drips onto unrinsed shrubs burns their leaves brown. Bleach with no surfactant runs off the wall before it has time to kill much.
When to Book Soft Washing in Port Huron Township
Soft washing works from April through November on any day above freezing. Growth speeds up once nights turn warm and muggy, so an April or May wash clears the buildup from the winter before that stretch. On north-end lots by the Black River, a wash after the trees leaf out still leaves a clean summer ahead, and a fall wash after leaf drop removes the season's growth before the walls sit wet through the cold months.

Soft Washing in Port Huron Township: FAQs
Is soft washing the same as power washing?
No. On the shaded north wall of a 2000s township house, the siding gets a diluted solution and a rinse at about hose strength, since a hard stream drives water behind the laps, where it dries slowly on these damp lots. Higher pressure is kept to flat concrete, such as a driveway salted by traffic off Lapeer Rd, where a rotary surface cleaner spreads it evenly.
How long does a soft wash hold here?
Two to three years is the usual span for a shaded wall, and walls in full sun go longer. A north wall backed by one of the wooded pockets or close to the Black River bottomlands sits at the short end, because it stays wet the most hours. Washing only that wall halfway between full cleanings keeps it even with the rest of the house.
Will the rinse water reach Stocks Creek, Bunce Creek or the Huffman Drain behind my yard?
No, it is kept out of the creeks and drains. Beds and plants are wetted first, the mix is cut to the weakest strength that works, and the rinse dilutes it further. On a lot backing onto one of those drains or creeks, the rinse is kept away from the ditch, the culvert and any catch basin, and the wash goes on a dry day so a storm does not carry runoff into the drain.
Can you soft wash my roof on the same visit?
Yes. A roof gets the same chemistry-first approach, with a mix made for asphalt shingles and a rinse no stronger than a hose, and roof treatment starts at $450. Doing both together makes sense when the north wall and the north slope sit under the same shade. Our roof cleaning page explains the process for township roofs.
