Black streaks, green film and gray stains removed from siding and trim, with advice on stopping the cycle.
Black spots, green film and gray streaks on siding are usually algae, mildew or mold feeding on dirt and moisture. They grow fastest on shaded walls, under trees, near sprinklers and anywhere air does not move. They are not just ugly. They hold moisture against the surface, can stain permanently if left too long and can be a sign that water is not draining as it should.
We treat these stains gently with cleaning solutions that kill the growth at the root, followed by a low-pressure rinse. We look for the reason it is growing, such as a clogged gutter, a sprinkler hitting the wall, overgrown shrubs or a leak, and talk about simple fixes. If we find mold that is more than a surface stain, such as growth inside walls or under siding, we recommend a specialist, since that is a different kind of problem. Often a clean wall and a few habit changes keep the house bright for years.
A proper cleaner kills growth at the root so it does not return in a few weeks.
Moisture sources like sprinklers, gutters and shrubs are noted so you can reduce regrowth.
We avoid harsh pressure that can damage vinyl, wood and fiber cement.
Growth inside walls needs a specialist. We tell you if we see signs of it.
