How Much Does Pressure Washing Cost in Cambridge, MA? (2026)

A full exterior wash on a Cambridge triple-decker usually runs somewhere around $550 to $1,100. That figure surprises people who priced a ranch house in the suburbs, where the same crew might charge $300 to $450. Height, tight lot lines, and the hassle of parking a rig on a narrow street all push Cambridge, MA prices up.

The good news is that most of the cost comes down to a handful of predictable things. Once you know whether your house is clapboard, vinyl, or brick, how tall it is, and how close the neighbors sit, you can estimate a fair quote before anyone shows up with a ladder.

Typical Prices by Job Type in Cambridge

Most Cambridge homeowners pay roughly $0.25 to $0.60 per square foot of surface for house washing. Flatwork like walkways, patios, and driveways tends to land between $0.20 and $0.45 per square foot. Nearly every local company also has a minimum charge of about $200 to $300, so a quick front stoop rinse will not cost $40.

The table below shows ballpark ranges for common Cambridge jobs. Treat these as approximate starting points, since every house and every crew is a little different.

Bundling usually saves money. A crew that is already set up for the siding will often add the porches and walkway for less than it would charge to come back on a separate day.

Why Cambridge Costs More Than the Suburbs

Labor in the Boston metro is expensive, and pressure washing crews pay the same rents and insurance premiums as every other trade here. A two-person crew with a truck, a soft wash system, and liability coverage has to bill a few hundred dollars per half day just to break even. That baseline is higher in Cambridge than it is in Worcester County.

The buildings themselves add more. A typical triple-decker stands three full stories plus a peaked roof, so the top clapboards can sit 35 to 40 feet off the ground. Crews either soft wash from the ground with extension wands and chemical reach or set up tall ladders, and both take time.

Tight Lots and Narrow Side Yards

Many Cambridge houses sit three or four feet from the next building. That gap makes it hard to swing a ladder, aim a wand, or keep overspray off the neighbor's car and windows. Crews price that extra care into the job, and some will ask you to give the neighbors a heads up before the work starts.

Shared driveways are common too. If the equipment has to sit in a driveway that belongs to two households, the crew needs both owners on board.

Parking and Street Permits

Finding a spot for a work truck and trailer on a permit-parking street near Porter Square can be a real problem. Some companies build a parking fee into Cambridge quotes because they expect a ticket or a long hose run from wherever they could find space. If the truck has to block part of the street, the city's Traffic, Parking and Transportation department handles temporary no-parking signs, and the contractor or homeowner should sort that out ahead of time.

Ask the company how it handles parking before you book. A clear answer usually means they work in the city often.

Siding Types and How They Change the Price

Clapboard is the most common surface on Cambridge triple-deckers and older two-families. Much of it is painted wood that is decades old, so a good crew will use a soft wash method: low pressure plus a cleaning solution that kills the mildew and algae. High pressure can lift old paint, force water behind the boards, and gouge soft wood, and fixing that costs far more than the wash.

Vinyl siding is easier and a bit cheaper to clean. It handles moderate pressure, dries fast, and rarely needs a second pass. Expect the low end of the per-square-foot range on a vinyl-sided house of the same size.

Brick Rowhouses and Older Masonry

Brick rowhouses near Harvard Square and along the older blocks of Cambridgeport need a gentler touch than most people expect. Old brick and lime mortar are softer than modern materials, and a high-pressure tip can wash out mortar joints or scar the face of the brick. Experienced crews use low pressure, a masonry-safe cleaner, and plenty of dwell time.

That slower process is why brick facades often cost as much as a larger clapboard house. You are paying for the time it takes to do it without damage.

Historic Districts and Old Houses

Cambridge has several historic and neighborhood conservation districts, including areas of Mid-Cambridge and around Harvard Square. Routine cleaning does not usually need approval, but anything that changes the exterior can. If a contractor suggests sandblasting, chemical stripping, or sealing old brick, check with the Cambridge Historical Commission first.

Owners of older homes should also think about lead paint. Many Cambridge houses were built well before 1978, and blasting chipped paint off clapboards can scatter lead dust into the yard and onto the sidewalk. A careful crew will use soft wash on painted wood and avoid stripping paint unless it is part of a lead-safe painting job.

Cambridge Water Rules and Runoff

Wash water does not simply vanish down the street. In Cambridge, storm drains carry runoff toward the Charles River and the Alewife area, and the city does not allow washwater with detergents or debris to be dumped into catch basins. Reputable crews block drains, use biodegradable cleaners, and steer runoff into planting beds or grass where possible.

That extra setup can add a little to the quote, and it is worth paying for. A company that shrugs off the question of where the water goes is a company you should skip.

Water itself is rarely a separate line item. Most crews hook up to your outdoor spigot, and the amount used on a typical house wash adds only a few dollars to your Cambridge Water Department bill.

How Neighborhoods Shape the Quote

Location inside the city changes the logistics more than the base price. A crew might charge a similar rate per square foot everywhere, but some streets take longer to work on than others.

Porter Square and the streets around it are full of triple-deckers and two-families on small lots, often with resident permit parking. Expect quotes near the middle to upper end of the ranges above, mostly because of height and access.

Mid-Cambridge has a mix of large Victorians, brick rowhouses, and multi-unit buildings. Many sit inside a conservation district, so expect a crew to lean toward low pressure and slower methods on painted trim and masonry.

Cambridgeport and the River Side

Cambridgeport has dense blocks of worker cottages, triple-deckers, and newer infill buildings, all fairly close to the Charles River. The damp air off the river feeds green algae on shaded north walls, so these houses can need cleaning every two years or so. A first wash on a badly stained wall may take two passes, which can add $100 to $200 to the bill.

Smaller cottages in this area are often the cheapest full-house washes in the city. A one-and-a-half-story house on a small lot might cost $350 to $550.

When to Schedule and How to Save

Cambridge crews do most of their work from April through early November. Spring is the busiest window, since everyone wants the winter grime and pollen gone at once. Booking in late summer or early fall can mean faster scheduling and, with some companies, a small discount.

Avoid washing in freezing weather. Water left in gaps between clapboards can freeze and expand, and cleaning solutions do not work well when it is cold.

Here are a few ways homeowners in the city keep the bill down:

• Bundle the siding, porches, and walkway into one visit
• Coordinate with your building neighbors so a crew can wash two attached units in a row
• Trim shrubs and move porch furniture yourself before the crew arrives
• Ask for a soft wash maintenance price every two to three years instead of waiting for heavy staining

Hiring the Right Crew in Cambridge

Massachusetts does not require a specific state license for pressure washing on its own. That means you should ask for proof of general liability insurance before anyone works on your home. Ask how they plan to protect windows, plants, cars, and the house next door, too.

A good quote will spell out the method, the surfaces, and whether drain protection is included. If you want to compare local companies, you can browse Cambridge pressure washing pros in our directory and request a few written estimates.

Get at least two quotes on a triple-decker. Prices on the same building can easily differ by a few hundred dollars depending on how a company handles height and access.

Frequently Asked Questions

How much does it cost to pressure wash a triple-decker in Cambridge?

Most owners pay about $550 to $1,100 for a full exterior wash. The price climbs if the top floor needs ladder work or if the walls carry heavy algae from years without cleaning.

Is pressure washing safe for old clapboard siding?

Low pressure soft washing is the safer choice for painted wood clapboards, which are common on houses built before 1940. High pressure can strip paint and push water behind the boards, so ask any crew which method it plans to use.

Do I need a permit to pressure wash my house in Cambridge?

A routine wash usually does not need a permit. You may need temporary no-parking signs if the work truck has to occupy the street, and projects that alter a building in a historic district can require Cambridge Historical Commission review.

How often should Cambridge homes be washed?

Every two to three years works for most houses. Shaded walls near the Charles River or under large street trees may need cleaning closer to every 18 months.

Can I clean my brick sidewalk myself?

You can with a garden hose, a stiff brush, and a mild cleaner, which costs under $50. Renting a high-pressure machine for old brick pavers risks blowing out the sand joints, so many owners leave that work to a pro charging around $150 to $275.
