House Washing in Mount Clemens
A wash on these streets begins with the wall, not the machine. Brick from the 1880s, painted clapboard under ornate trim, and postwar siding out toward the Clinton Township line each take their own mix, and one house often wears two of the three.
Three eras of exterior meet inside one city here. The old streets near downtown and the Clinton River hold Bath City era homes from the years the mineral-bath industry ran, 1873 to 1974, most of them original brick or painted wood under ornate trim. The original grid filled in with early-1900s through 1920s houses that share those materials and those close-set lots. Out toward the Clinton Township line, the postwar homes carry later siding, wider drives and less hand-cut detail. Gratiot Ave runs north and south through all of it, and houses within a block or two of the corridor wear a gray traffic film the others do not.
What grows on a wall is set by shade and moisture. The residential streets between downtown and the river carry the big trees of a city platted before 1879, MacArthur Park adds bank shade on both sides of the water downtown, Shadyside Park does the same downstream, and the lake-plain clay under these lots drains slowly after a storm. A north wall in that setting stays damp until mid-morning through most of the spring. Algae takes hold wherever a surface stays wet, so the shaded elevation greens first and darkest, usually a year or two ahead of the sunny side.
The wash is built to kill that growth rather than shave it. Solution goes on at low pressure, dwells while the biology dies, and rinses off at something close to garden-hose force, which is the only safe level on century mortar and old paint. Shaded walls hold two to three years after that, and walls in full sun hold longer. House washing starts at $349 and includes the porch, the garage door and the trim we can reach from the ground. The written quote lands within 24 hours, with no travel charge on it.
How the Wash Runs on an Old House
The walkaround comes first. We note the material on each elevation, the condition of the paint and mortar, and any window glazing that needs a hand worked around it, then we soak the beds and shrubs. Solution is applied from the ground with equipment that reaches a second-story eave, so no ladder ever leans against old siding. It dwells while the algae and mildew die, then a low-pressure rinse carries everything down and away, elevation by elevation from the top so nothing re-streaks. Porch turnings, cornice brackets and sills are worked by hand. Two to three hours covers a typical two-story.
What Damages These Walls
Force is what hurts them. A tight spray pattern held close cuts the mortar joints out of an 1890s wall in seconds, and repointing costs more than a decade of washing. On painted clapboard that same pressure drives water behind the laps, where it sits in the sheathing, and lifts coatings that were still sound. Wand stripes across a flat elevation show for years in low afternoon light. The quieter failure is a rinse-only wash that looks clean in May and is green again by September, because the roots were never killed.
Timing It Right
Any frost-free month works. April through June is the busiest run, when winter film comes off ahead of graduation parties and summer hosting, and families in the Mount Clemens Community School District book that stretch first. September and October bring a second wave, usually paired with a gutter clearing so the year ends clean. Mid-summer is the quietest window if you would rather pick your own date.

House Washing in Mount Clemens: FAQs
What does a house wash cost here?
From $349 for a typical two-story, with square footage and buildup setting the rest. Every surface gets its own line on the quote, so the porch, the walks and the garage can be approved separately. Putting a driveway or the gutters on the same visit runs cheaper than a second trip, because the setup is already paid for.
Can you wash painted wood siding without stripping the paint?
Yes, where the paint is still bonded. We keep the surface wet, hold pressure at rinse level and let the solution lift the film, so nothing works its way under the coating. Where paint has already failed or cupped, a wash will reveal it rather than cause it, and we point that out during the walkaround instead of afterward.
How long will the siding stay clean?
Two to three years on shaded elevations and longer on sunny ones, because the growth is killed at the root instead of rinsed off the top. Houses on the damp blocks near the Clinton River, under the oldest street trees, sit at the short end of that range. Washing that one elevation on its own between full washes is a fair way to stretch the cycle.
Do you wash the tall two-and-a-half story homes with steep gables?
Yes. Solution is applied from the ground, so height is a reach question rather than a ladder question, and nothing rests against the siding or the gutter. Steep gables, dormer cheeks and the trim above a porch roof get the same low-pressure treatment as the first floor. If a detail is too fragile to clean safely, we say so.
