Soft Washing in Algonac

On a canal lot, the wall that needs the strongest mix is often the one closest to the water. The St. Clair River is a binational Area of Concern, and the canals and the North Channel are part of that river system, so a soft wash in Algonac is planned around keeping the solution out of the water after it leaves the siding. On a narrow canal lot that means keeping it off the seawall and out of the canal, and the steps below are built around it. The water side is usually the back of the house on these lots, often under a deck or porch roof, and it carries the heaviest growth because it dries last.

Green film on siding is algae, and gray, black or speckled patches are usually mildew. Both live in the dirt and moisture held in textured vinyl, open wood grain and the pores of brick. They spread during the hours a wall stays damp, which on a lot with a canal at the back means the lower siding courses, a wall under a deep porch roof, and any side that the next house shades through the morning. A soft wash coats those surfaces, lets the solution sit until the growth dies, and rinses it away gently, without the scratches a close wand leaves in vinyl.

Shade adds to it at the north end of the city. The master plan describes the 38-acre stretch along the northern city border, between Washington St and Michigan St, as mostly wooded with wetlands, and Algonac State Park lies beyond it in Clay Township. Houses beside that cover get less sun on their walls and more leaf litter at the foundation, both of which keep siding damp longer than on an open lot. Our post on why waterfront homes grow mildew faster covers the moisture side.

Why a Canal-Side Wall Greens Again

Water pressure with no cleaning agent clears the color for a few weeks, but the growth living in the siding texture survives, and on a damp wall facing a canal the green often returns before the next summer. The force also scuffs vinyl and lifts the grain of painted wood, which leaves more surface for new growth to hold. On a canal lot there is a second risk. Mix sprayed into the air drifts, and mix rinsed onto pavement runs off, and on these lots both can reach the water a few yards away.

When to Book Soft Washing in Algonac

Late spring and early fall are the two good windows, with nights above freezing. Spring works once winter growth shows and before summer humidity speeds it up. Early fall clears a season of growth before the house closes up for cold weather. Walls facing the North Channel or a canal may want a light maintenance wash sooner than inland walls on the same grid, and the quote can price those walls on their own.
