Roland Park was one of the first planned suburbs in the country, and the houses show it — shingle-style exteriors, original stucco, stone, slate roofs and woodwork that has been there for over a century. These are the least forgiving surfaces we work on, and they are exactly the ones people damage by hiring on price.
Slate is the one to be careful with. It is brittle, the fixings are old, and walking a slate roof or hitting it with pressure will cost far more to repair than any cleaning was worth. We treat slate from the ground with low pressure and let the solution do the work. Original stucco gets the same restraint.
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. Roland Park is a straight run down the Jones Falls for us. We are not a franchise driving out for the day.

Insured, and careful with your property. We protect plantings, close up before we start and rinse everything down at the end. No dead shrubs, no soap film left on the glass.
One crew for the whole exterior. Plenty of Roland Park customers have us wash the house and clean the windows in Roland Park on the same visit — cheaper than two companies and done in one morning.
Most Roland Park homes run $450 to $900, reflecting the size of the houses and the care original materials require. Driveways usually run $150 to $300. Send a photo or your address and we will text you an exact price — no site visit needed in most cases.
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, but only by soft washing from the ground. Slate is brittle and old fixings give way, so nobody should be walking it or putting pressure on it to clean off moss. Done properly the moss dies off and washes away over the following weeks.
Every one to two years for most homes. Maryland humidity feeds mold and algae, and the old-growth trees through Roland Park keep roofs and north elevations 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.
