Power Washing in St. Clair, Michigan

An Old River Town Beside the Shipping Channel

This page covers the city of St. Clair on the river, a city of 5,464 people at the 2020 census, where lake freighters pass the downtown riverfront on the Great Lakes Waterway. Robert Fulton platted the town on the north side of the Pine River in 1817. Sawmills and about a century of shipbuilding followed, and the city's history says numerous ship captains built homes here. About a quarter of today's housing dates to 1939 or earlier and another quarter to 1940 through 1959, so most exterior work here is on older walls that need low pressure.

Shade is the second condition. St. Clair was named a 2024 Tree City USA, its 26th year, so the city has run a managed street-tree program for more than two decades. Where one of those trees overhangs a house, the north wall and the roof stay shaded and hold dew longer, and green film on siding and black streaks on shingles follow. That shade, more than the age of the house, decides how soon a wall or roof needs cleaning again, and the same trees fill the gutters each fall.

Salt is the third. M-⁠29 runs through town as Riverside Ave and River Rd along the shore and as Oakland Ave south of the Pine River, and Fred W. Moore Hwy carries traffic in from I-⁠94. All winter, passing cars throw salt brine and tire dust at the walls, steps and drives that face these roads. On the siding it dries into a gray film with an oily binder, which water alone smears. That wall needs a detergent that cuts oil before the rinse, and the drive needs its salt residue cleaned off each spring.

Starting prices match Macomb County: house and soft washing from $349, with most houses $349 to $700; roof treatment from $450; driveway cleaning from $149, most $200 to $350; gutter cleaning from $149, most two-story houses $175 to $300; deck cleaning from $199 at $1 to $2 per square foot.

Old Plats, Recorded Subdivisions and Rentals

Many of the oldest houses stand on the Map of St. Clair plat near the Pine River and downtown. Painted wood trim on a house that old may carry many coats, and a narrow high-pressure stream lifts any coat that has lost its bond. A mild mix and a rinse near garden-hose pressure leave sound paint where it is, and anything already failing should be pointed out to you before the wash starts. The house washing page covers the rest of an older wall.

Recorded plats cover other parts of the city, among them Oakwood Subdivision, Jackson Farm Subdivision and Norby St. Clair Subdivision on the west side, and The Highlands and Palmer Village Subdivision on the north side. A west-side lot sits well back from the shore, yet its runoff still ends in the St. Clair River by way of the county drains. So the rinse rule matches River Rd: the weakest mix that works on each wall, beds soaked before and after, and the rinse kept out of the street drain at the curb.

About 32% of the city's occupied homes are rented, and the city requires every residential rental unit to be registered with its Building Department. An owner who lives elsewhere tends to see the front of the house, while green growth starts on the north and back walls that stay damp longest. Ask the tenant for photos of every side to send with the estimate request. Then the itemized quote prices the shaded walls too, and you approve each surface before the visit.
