The green film on the north side of a Glenmont house isn't dirt. It's living algae, fed by Hudson Valley humidity and long shoulder seasons, and rinsing it off the surface just resets the clock for about eight weeks.
Glenmont homes sit close to the river along River Rd and the Hudson bluffs, where morning fog lingers well past sunrise. That extra hour or two of damp is exactly what mildew needs, and it shows up first on shaded siding and around gutter lines.
Our soft wash applies professional detergents at lower pressure than a garden hose, kills the growth at the root, then rinses everything clean — siding, soffits, gutters' exteriors, trim, and shutters. Results last three to five times longer than a pressure-only wash.
