House Washing in St. Clair Shores
A St. Clair Shores house wash depends on which side of Jefferson Ave you live. On the grid it is brick and chalking aluminum trim from the 1950s and 1960s. On the canals it is siding that weathers in bands from the seawall up. The crew reads that before a hose comes off the truck.
Most of the houses we wash in St. Clair Shores were built in the same ten years. The population nearly quadrupled between 1950 and 1960, and the grid between Harper Ave and Jefferson Ave filled with brick ranches and bungalows trimmed in aluminum, many of them re-sided in vinyl or aluminum since. That brick has carried sixty-plus winters in its mortar, and the aluminum trim has chalked to a powder that smears under an ordinary wash. North walls under the 60-to-70-year-old street trees grow the green film first, and the western streets near I-94 add a gray salt film every winter on top of it.
The canal homes off Jefferson Ave between 9 Mile and 10 Mile are the same era with a different exposure. Still canal air between close-set houses holds humidity and fog into late morning, so the water-facing siding logs more wet hours than the front and grows a band of algae at mid-wall. Below it, the seawall cap and the lowest courses take wake splash and winter ice. Above the dock, cleats and railing anchors bleed rust down the wall after every rain. Three bands, three kinds of chemistry, one visit.
The wash is built around that reading. Brick takes a gentle mix at rinse pressure so the joints keep their mortar. Aluminum gets a pre-treatment for the chalk before the wash so the powder lifts evenly. Vinyl and the canal siding get standard soft-wash chemistry, applied low and rinsed at garden-hose pressure so nothing is forced up under the laps. The growth dies at the root instead of being sheared off, which is why a shaded or canal-facing wall stays clean two to three years and a sunny one longer. Pricing starts at $349, the quote itemizes every wall and walk, and the drive from our Clinton Township shop is about 20 minutes.
How the Crew Works a Shores House
The walkaround comes first: which walls are brick, which are aluminum or vinyl, where the paint is thin, and where the canal or the neighbor's dock sits relative to the rinse. Beds and lawn get pre-wet. Solution goes on from the ground with reach to the eaves of a second story, dwells while the algae and mildew die, and rinses off at garden-hose pressure from the top down. On a canal lot the crew rinses toward the lawn and the drains, never over the seawall. Chalked trim gets its pre-treatment, the garage door and the porch are included, and a typical ranch takes about two hours, from $349.
What Goes Wrong on These Walls
Pressure is the usual mistake. A rented machine held close to sixty-year-old mortar cuts the joints. On chalked trim the same wand strips the powder in stripes that show every evening when the sun drops behind the house. On vinyl it forces water behind the laps and into the sheathing, where it stays. The second mistake is washing a canal wall with one mix: house-wash solution does nothing for the rust below the dock cleats and too much for the seawall cap. The third is rinsing without killing, which looks fine in June and is green again by Labor Day.
Timing It Right
April and May are the busiest weeks, when owners want the winter film and the I-94 salt off before the annual Memorial Day Parade and before the boats go in at the marinas. A second wave follows the June fish-fly hatch, once the residue on lakeside siding starts feeding a new crop of mildew. Any frost-free month works for the chemistry, and September is the quietest time to get a canal-facing wall done before the fog season sets in.

House Washing in St. Clair Shores: FAQs
How much is a house wash on a St. Clair Shores ranch?
From $349. A single-story brick ranch on the grid usually lands near the starting price because the walls are short and the aluminum trim is the only extra step. A canal home with a rebuilt second story and three bands to treat runs higher, and the quote shows each wall and the seawall walk as separate lines so you can choose what to do now.
Will the fish flies come off with the wash?
Yes, and sooner is better. The June hatch coats lakeside siding within weeks, and the residue is fertilizer for the mildew that follows it. Our solution dissolves the bodies and the streaks under them, and the rinse carries it all off. Owners near Blossom Heath Park and the Nautical Mile often book the wash for early July for that reason alone.
Can you wash the chalking aluminum trim without making it worse?
Yes. Chalk is oxidized paint, and a plain wash smears it into streaks. We pre-treat the trim so the powder lifts evenly and rinse it low. If the finish is down to bare metal in places, we say so at the walkaround, because a wash cannot bring paint back and you should decide before spending on it.
Does the soap end up in the canal?
It is planned not to. Rinse angles point toward the lawn and the storm drains rather than the seawall edge, wash water is directed away from the canal, and the chemistry sits at the biodegradable end of the professional range at siding dilutions. The seawall cap gets masonry treatment at low pressure so the joints stay sealed against the water.
