A lot of Timonium went up in the sixties and seventies, which means split-levels and ranchers with mixed elevations — brick on the lower half, siding above, sometimes a painted panel between. That combination is the thing people get wrong. Brick will take pressure, the siding above it will not, and they sit on the same wall.
Homes closer to the York Road corridor also collect traffic film on the front elevation, which is oily rather than organic and needs detergent rather than force. We work a Timonium elevation surface by surface instead of running one setting across the whole thing.
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. Timonium is roughly twenty-five minutes 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 Timonium customers have us wash the house and clean the windows in Timonium on the same visit — cheaper than two companies and done in one morning.
Most Timonium homes run $300 to $600 depending on size and how much buildup there is. 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.
Not at all, and it is extremely common in Timonium. Brick and siding just get handled differently on the same wall: appropriate pressure on masonry, low-pressure soft washing on the siding above it.
Every one to two years for most homes. Maryland humidity feeds mold and algae, and the mature plantings around older Timonium lots keep the lower siding shaded and slow to dry. 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.
