AWP Exterior Cleaning operates across Greater Clark County, handling roof cleaning, house washing, gutter maintenance, and concrete pressure washing for residential and commercial properties. The crew uses soft-wash methods that protect shingles and siding from high-pressure damage, and all technicians carry commercial pesticide applicator licenses required by the Washington State Department of Agriculture for moss treatment work.
Western Washington's constant moisture means moss and algae establish within 18–24 months of roof installation. Left untreated, moss lifts shingle edges and accelerates granule loss. AWP treats growth at the root with low-pressure application and EPA-registered products, then manually brushes and rinses without tearing the roof surface. The same approach applies to siding — soft washing breaks down organic buildup without forcing water behind caulk seals or stripping paint.
The business handles gutter cleaning with hand-scooping and downspout flushing, concrete cleaning with surface cleaners that prevent tiger-striping, and deck or fence cleaning with controlled pressure adjusted to wood type and age. Most residential jobs finish in one visit, and the crew provides before-and-after photos for every project. Same-week availability is typical during spring and summer; fall schedules fill faster as gutter-cleaning demand peaks before winter.
