What Does Every Visit Include?
Every estimate is free, and most quotes come back in about 48 hours. Jobs start at $150, and pressure washing carries our Satisfaction Guaranteed promise: if you are not satisfied, we re-clean the area at no charge.
The cleaning itself uses low pressure matched to the surface. Vinyl siding gets water no hotter than 110 F, brick gets 600 to 900 PSI, and roofs get a mild, roof-safe cleaning solution with no pressure over 50 PSI. We filter and reclaim wash water so it does not run into storm drains.
Most siding makers suggest washing every 12 months, and a yearly visit keeps algae from taking hold. Ask about a yearly visit when you book your first wash.
What Kinds of Properties Do We Clean?
We clean houses, townhomes, driveways, patios, decks, fences, gutters, and roofs. For businesses we clean building exteriors, parking areas, dumpster pads, and storefronts, and we take on government and campus work.
Small jobs are welcome. A front steps and sidewalk wash is a common first visit. Browse our full list of services, such as our house washing service for siding and brick. Property managers can start with commercial power washing services for larger buildings.
How Do You Book a Wash in Your Town?
The fastest way to book is the online estimate form, or you can call 301-762-9274 and tell us your address and what needs cleaning.
Tell us the town, the surfaces, and anything you worry about, such as old mortar, painted wood, or a roof that has gone dark. We will answer with a price you can say yes or no to.
After you send your address, the estimate works like this. We review the surfaces and the size of the job, we send a written price, and you pick a day. There is no charge for the estimate, and you decide after you see the number.
How Do We Clean Different Surfaces?
Each surface gets its own method, and the method decides the result.
Concrete driveways, walks, and patios get a flat surface cleaner, which keeps the finish even from edge to edge. Wood decks need time to dry, about 48 hours or until the wood reads 12% moisture content, before any sealer goes on. Composite decks skip that wait, but they collect algae in the seams, and a gentle pass clears it.
Gutter cleaning includes the downspouts. Packed gutters hold water against the fascia, and that is how rot starts.
Roofs are the surface people ask about most. Black streaks are usually algae, and they can degrade shingle granules over time. High pressure is likely to damage asphalt shingles, so roofs get the gentle method instead.
Who Will Show Up at Your Property?
PowerWashCompany.com has served Maryland since 1989 from our Gaithersburg office at 16622 Oakmont Ave. We are veteran-owned, and customers rate us 4.8 stars across 387 Google reviews.
Our crews work out of that one office, so the people who answer the phone are the people who schedule your visit.
Why Does Where You Live Change the Job?
Shade, tree cover, the age of the siding, and the surface itself all change how we clean. Wooded Montgomery County lots tend to hold moisture on shaded walls, and that moisture can feed algae.
Brick, vinyl, concrete, and painted wood each need a different setup. That is why each town page covers its own conditions rather than repeating one script across Montgomery County. A north wall under tall trees stays damp longer than a south wall in full sun, so two houses on the same street can need different visits.
What If Your Town Is Not on the List?
If you do not see your town on the list, call 301-762-9274 and tell us the address. We will tell you plainly whether we can take the job, and what it would cost.
New town pages go up as we build them, and a missing page only means we have not written it yet. Sending a photo helps. A picture of the siding, deck, or driveway lets us price the job closely before anyone drives out.
