Parkville is mostly forties through sixties housing on small lots, and that brings surfaces you do not see much in newer neighbourhoods — formstone, painted brick, original asbestos-cement shingle siding, aluminium from a later re-side. None of those take kindly to high pressure. Formstone in particular will lose its face if someone gets aggressive with it.
Lots being close together is the other factor. Side walls sit a few feet from the neighbour’s, get almost no sun, and grow mildew heavily while the street-facing elevation still looks passable. That side is usually the one that needs the most work.
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.
Local. Parkville is a straightforward run for us round the top of the Beltway. We are not a franchise driving out for the day.

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, at low pressure. Formstone is a surface coating and high pressure can take the face straight off it, which is not something you can put back. We soft wash it and test a small area first, and we will tell you up front if a section is already failing.
Every one to two years for most homes. Maryland humidity feeds mold and algae, and Parkville’s tight lot spacing means side walls get little sun and grow mildew quickly. 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.
