Pressure Washing Cost in Maryland (2026 Price Guide): House, Driveway, Deck, and Roof Rates

Pressure washing cost in Maryland for 2026: house, driveway, deck, and roof prices by region, soft wash vs. high pressure, scheduling tips, and hiring checks.

Pressure Washing Cost in Maryland (2026 Price Guide): House, Driveway, Deck, and Roof Rates

Pressure washing a typical Maryland home costs $275 to $600 for the siding, $150 to $350 for a two-car driveway, and $200 to $500 for a deck in 2026. Bundle all three and most companies in the Baltimore and Washington suburbs will land somewhere between $500 and $1,100 for the whole property.

Maryland's humid summers are the reason this is a yearly expense rather than an occasional one. Green algae on north-facing vinyl, black mildew streaks on roofs, and the gray film that builds up on concrete all come back every season, and homeowners from Frederick to Salisbury spend money on it every spring.

Price by Surface

House washing is priced by square footage and stories. A one-story rancher in Glen Burnie with 1,500 square feet of vinyl runs $250 to $400. A two-story colonial in Columbia or Bowie with 2,500 square feet runs $400 to $650, and a three-story townhouse end unit in Germantown can hit $500 because of the ladder work.

Driveways are priced by area. A standard two-car concrete driveway of 400 to 600 square feet runs $150 to $300, and long driveways in rural Carroll or Howard County can reach $400 or more. Paver driveways cost more because they need a gentler wash and often resanding afterward.

Decks and patios run $200 to $500 for wood and $150 to $350 for composite or concrete. Wood decks in Maryland tend to need a lower-pressure wash with a brightener, and sealing afterward is usually a separate charge of $1 to $3 per square foot.

Roofs are a special case. Maryland's asphalt shingle roofs get the black streaks caused by algae, and the correct treatment is a soft wash with a cleaning solution rather than pressure, which would strip the granules. Roof cleaning runs $400 to $900 for an average home and is one of the more expensive line items.

Fences, sidewalks, and pool decks round out the list. A 150-foot wood privacy fence costs $200 to $450 to wash, a front walk is often $50 to $100 when added to another job, and a pool deck in Anne Arundel County runs $150 to $350 depending on size.

Soft Washing Versus Pressure Washing

Most of what gets called pressure washing in Maryland is soft washing. Vinyl siding, painted surfaces, stucco, and roofs are cleaned with low pressure and a solution of sodium hypochlorite and surfactant that kills the algae and mildew rather than blasting it off.

High pressure is for hard surfaces. Concrete, brick, and stone can take 2,500 to 3,500 PSI, and that is what removes the gray film from a driveway or the moss between patio pavers. A company that uses high pressure on your siding will leave streaks, force water behind the panels, and can void a siding warranty.

Ask which method a company plans to use on each surface. A good answer distinguishes between the roof, the siding, and the concrete, and explains why. A company that quotes one price for "pressure washing everything" is a sign to keep calling.

Soft washing costs a bit more per square foot because of the chemicals, but it lasts longer. A soft-washed house in the Maryland climate typically stays clean for 18 to 24 months, while a high-pressure wash that only removes surface growth can look dirty again by the following spring.

Regional Price Differences in Maryland

Montgomery County and the Washington suburbs are the most expensive market. Companies serving Bethesda, Potomac, and Rockville quote $450 to $800 for a house wash, partly because the homes are larger and partly because of the local cost of running a business.

Baltimore City and County sit in the middle. A rowhouse in Canton or Hampden costs $150 to $300 to wash because the front is small, and a single-family home in Towson or Catonsville runs $300 to $500. Howard and Anne Arundel Counties price similarly to Baltimore County.

Frederick, Hagerstown, and Western Maryland run 10% to 20% below the metro areas. The Eastern Shore is mixed: Ocean City rentals are priced high because of demand and salt exposure, while inland homes around Easton and Salisbury are among the cheapest in the state to wash.

Southern Maryland, including Waldorf, La Plata, and Lexington Park, has a lot of newer vinyl-sided homes on wooded lots, and the combination of shade and humidity means those houses need washing more often. Prices there track closely with the Baltimore suburbs.

When to Schedule and How Often

Spring is the busiest season, and companies from Annapolis to Westminster book out three to four weeks in April and May. If you want a specific date before a graduation party or a listing photo shoot, call in March.

Fall is the smart alternative. Washing in October removes the summer's growth, gets pollen and leaf stains off before winter, and companies often have open calendars and occasionally discount. Cold weather washing is possible but many companies stop when temperatures drop below 40 degrees because the chemicals work poorly.

Most Maryland homes need siding washed every one to two years. Homes with north-facing walls under trees, which describes much of Columbia and Silver Spring, lean toward yearly. Driveways and decks usually go two to three years between washes unless they are shaded.

Pre-listing washing is one of the better returns in home selling. A $500 wash of the siding, walk, and driveway changes how a house photographs, and agents in the Baltimore and DC suburbs regularly recommend it before listing.

Vetting a Pressure Washing Company

Insurance is the first question. Pressure washing can crack windows, strip paint, blow out screens, and kill plants, and a company without general liability coverage leaves you holding the damage. Ask for a certificate with at least $1,000,000 in coverage.

Maryland does not require a specific license for pressure washing, so the next check is experience with your surfaces. Ask what solution they use on roofs, how they protect landscaping, and whether they rinse plants before and after. A company that pre-wets and covers your boxwoods knows what sodium hypochlorite does to shrubs.

Ask whether they carry a contractor license if the job includes anything beyond cleaning. Sealing a deck, repairing siding, or replacing gutters after a wash falls under the Maryland Home Improvement Commission, and a company doing that work should hold an MHIC license you can look up.

Water source is worth clarifying. Most companies use your outdoor spigot, and a full house wash uses several hundred gallons. If you are on a well in Harford or Carroll County, tell them, because some will bring a water tank.

Get the quote in writing with each surface itemized. A bundled price is fine, but you want to know what happens if you drop the deck or add the fence.

Doing It Yourself Versus Hiring

A rented pressure washer from a home improvement store costs $75 to $120 per day, plus $30 to $50 for cleaning solution. For a driveway or a small patio, that is a reasonable Saturday project, and the savings over a $200 professional job are real if you already own a ladder and do not mind the time.

Siding and roofs are a different story. Doing a two-story house from a ladder with a pressure wand is a common cause of falls, and getting the chemical mix wrong on vinyl can leave permanent chalky streaks. Professionals use telescoping wands and downstream injectors that keep them on the ground.

Time is the other cost. A professional crew washes a full house, driveway, and deck in two to four hours. The same work done solo with rental equipment typically takes a full day and a sore back.

For most Maryland homeowners, the split that makes sense is to rent for the flat concrete and hire out anything that needs a ladder or a chemical wash. That keeps the annual spend around $300 to $500 for a typical suburban lot.

Frequently Asked Questions

How much does it cost to pressure wash a house in Maryland?

Most two-story homes run $400 to $650 for the siding alone, with smaller ranchers and townhouses starting around $250. Montgomery County prices run higher than the rest of the state.

How often should I have my house washed in Maryland?

Every one to two years for most homes. Shaded lots and north-facing walls collect algae faster and usually need it yearly.

Will pressure washing damage my vinyl siding?

High pressure can. Reputable Maryland companies soft wash siding with low pressure and a cleaning solution, which removes mildew without forcing water behind the panels.

Is roof cleaning worth the cost?

Yes if you have black streaks, which are algae feeding on the shingles. A $400 to $900 soft wash removes them and can extend roof life by several years compared with leaving the growth in place.

Do I need to be home for the service?

Usually not, as long as the crew has access to an outdoor spigot and the areas to be cleaned. Close windows, move cars and patio furniture, and let them know about any pets or plants that need protecting.
