Power Washing in Port Huron, Michigan

Old Houses, Three Waterfronts and Two Interstates

Port Huron sits where Lake Huron empties into the St. Clair River, and the Black River cuts through the middle of town to meet the St. Clair downtown. Over a third of the city's 12.27 square miles is water, and the master plan maps floodplain buffer zones along the lake, both rivers and the Black River Canal. On the River Park blocks facing the St. Clair River, in Ballentine along the Lake Huron shore and on streets that back onto the Black River, houses stand beside open water. Algae and mildew grow only while a surface is wet, so a wall that dries slowly after dew or rain gives them more hours each day.

The housing is old. Census survey data counts about a third of the city's homes as built in 1939 or earlier, and close to six in ten before 1960. Olde Town, between Military St and 10th St, holds Cape Cods, bungalows and Victorian houses from the 1930s or earlier, and River Park west of Merchant St dates to the 1920s. Houses of that age often still carry painted wood on trim, porches and siding. Old paint chalks and loosens at its edges, and a narrow, high-pressure stream peels it off in strips. Those houses get low pressure, a mild mix and a look at the paint before anything is sprayed.

Traffic adds a third layer. I-⁠94 and I-⁠69 both end at the Blue Water Bridge plaza inside the city, and their business loops run on Military St, Electric Ave, Huron Ave and Pine Grove Ave, with the Oak St and Griswold St one-way pair carrying BL I-⁠69 through residential blocks. Houses on those streets can collect salt spray on lower siding and curbside concrete each winter, plus a gray film of exhaust and tire dust on the wall facing the road. That film is oily, and it needs a detergent rather than more pressure.

The MPWS shop is at 21366 Hall Rd, Clinton Township, about 45 minutes from Port Huron by M-⁠59 and I-⁠94, and there is no travel fee for the trip. Crews carry $2M general liability plus workers' compensation, and the company holds 4.9 stars across 177 Google reviews. Starting prices for every service are on our pricing page.

How Port Huron's Housing Changes the Wash

The pre-1960 blocks are tight. Lots in Harrison Pointe run 40 to 60 feet wide, Mansfield lots are about 50 feet with alleys behind them, and Olde Town has the city's highest residential density. On lots that close, overspray can drift onto the house next door. Expect your plants to be soaked first and the spray in the side yard to stay low and off the neighbor's wall. A word to the neighbor before wash day helps.

The waterfront blocks vary. River Park's waterfront lots hold newer homes, and street trees are less common there, so those walls take sun as well as river air. Edison Shores, the 1990s townhome community, is heavily landscaped with large evergreen and deciduous trees, which shade its walls and roofs. It also has a homeowners association, so check its exterior rules and mention any notice deadline when you ask for a quote.

In Olde Town, the Historic District Commission reviews plans for exterior alterations and repairs before a permit is granted. A wash changes no material, but it shows what grime was hiding. The master plan notes dated facades showing wear in Olde Town, and on a clean wall, loose paint and soft trim are easy to see. Those spots are pointed out after the wash, so any repair can be planned and taken to the commission first.
