The green film on the north side of a Bethlehem 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.
Bethlehem covers everything from Delmar and Elsmere Colonials to farmhouses out toward Feura Bush and riverfront homes at Cedar Hill. The common thread is mature canopy and Hudson Valley humidity, which puts green algae on north-facing siding within a couple of seasons.
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.
