Most of Owings Mills went up from the nineties onward, and a huge number of those homes back onto a tree line or a common green strip. The front looks after itself — full sun, road frontage, everyone sees it. The rear is where the problem sits: shaded most of the day, damp from the trees, and completely out of sight until you go out there.
Rear decks and walkout patios take the worst of it. Composite and wood both grow a green film that gets genuinely slippery, and that is a safety issue more than a looks issue. On most Owings Mills jobs the back of the house takes twice the time the front does.
They are two different jobs, and using the wrong one is how siding gets wrecked. Pressure washing uses force and belongs on hard surfaces — concrete, brick and pavers. Soft washing uses very low pressure plus a cleaning solution that kills mold, mildew and algae at the root, and that is what belongs on siding, stucco and roofs.
The green-black film on the shaded side of a house is organic growth, not dirt. Blast it with pressure and you knock off the surface, drive water behind the siding, and it grows back within months because the roots survived. Soft washing removes it properly and it stays gone far longer. On asphalt shingles, pressure washing strips the granules and can void the roof warranty outright, so a roof only ever gets soft washed.
Book a house wash with us and you get soft washing on the siding with appropriate pressure on the concrete, decided surface by surface. Knowing which is which is our job, not yours.

It can. High pressure cracks vinyl, forces water behind panels and strips paint, which is why we soft wash siding instead. Low pressure and the right solution cleans better and does no harm.
Yes, and it is one of the most worthwhile things we do. That slick green film is algae, and it comes off with a low-pressure clean that will not splinter wood or scar composite. Grip comes back immediately.
Every one to two years for most homes. Maryland humidity feeds mold and algae, and rear elevations backing onto tree lines stay shaded and damp nearly year round. If you can see green on the siding, it is time.
Yes. Those streaks are roof algae and they respond to soft washing. We never put a pressure washer on shingles — it strips the protective granules and can void the manufacturer warranty.
