Columbia was designed around trees and paths rather than straight streets, and that design is why houses here go green. Homes sit tucked into woodland with pathways running behind them, so one or two elevations get almost no direct sun. In the older villages you also still find original cedar and T1-11 siding from the seventies, which is thirsty, soft and completely unsuited to high pressure.
Covenants are the other Columbia factor. Village associations do enforce exterior appearance, and a house wash is by far the cheapest way to deal with a notice about mildew or a dirty exterior — usually a few hundred dollars against the cost of painting or re-siding.
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. Columbia is a straight run down Route 32 from our Finksburg shop. We are not a franchise driving out for the day.
139+ five-star reviews. A straight 5.0 across every job, window cleaning and exterior washing alike.
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 Columbia customers have us wash the house and clean the windows in Columbia on the same visit — cheaper than two companies and done in one morning.
Most Columbia homes run $300 to $600, with older cedar-sided houses toward the top because they take more care. 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.
In most cases yes. Association notices about mildew, green siding or a dirty exterior are almost always resolved by a proper house wash, and it costs a fraction of painting. We can send you before and after photos to submit.
Every one to two years for most homes. Maryland humidity feeds mold and algae, and Columbia’s wooded village lots leave one or two elevations in shade nearly all day. 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.
