The green film on the north side of a Menands 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.
Menands homes along the Broadway corridor and Van Rensselaer Blvd take steady traffic film off Route 32 and 378, and the riverfront section adds humidity on top of it. The result is a gray road-grime layer over the mildew rather than one or the other.
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.
