How Much Does Pressure Washing Cost in Missouri? A 2026 Price Breakdown

A full exterior house wash on a 2,000 square foot Missouri home runs $300 to $550 in most of the state. Add the driveway and the front walk to the same visit and the total lands between $450 and $750. Kansas City and the inner St. Louis suburbs sit at the top of that band, while Springfield, Joplin, and Columbia tend to come in 10 to 15 percent lower.

Missouri homes need this work more often than owners expect, and humidity is the reason. Summer dew points here sit in the low 70s for weeks at a time, which keeps north and east walls damp long enough for algae to take hold on vinyl, painted wood, and even fiber cement.

The other half of the equation is winter. Freeze and thaw cycles pull road salt and de-icer into concrete, and by March most driveways in the Kansas City and St. Louis metros carry a gray film that no amount of rain will lift.

What You Pay by the Square Foot

Companies here quote house washing two ways. Some price per square foot of wall surface at $0.15 to $0.35, and others give a flat number after looking at photos or a satellite view of the property.

A single-story ranch around 1,400 square feet lands at $225 to $375. A two-story colonial at 2,500 square feet runs $400 to $650, because the crew needs ladders, longer hose runs, and more time working the upper courses safely.

Height moves the price more than area does. Anything taller than two stories usually adds $100 to $200, since the wash turns into a two-person job with a spotter and fall protection.

Older brick in St. Louis city and the northeast Kansas City neighborhoods gets its own treatment. Soft brick and lime mortar fail under a 3,000 PSI tip, so a careful crew drops to a low pressure rinse with a cleaning solution. That takes longer and prices out $50 to $100 above a comparable vinyl house.

Why Most Missouri Siding Gets Soft Washed, Not Blasted

The green and black film on the shaded side of your house is living growth, mostly algae with some mildew mixed in. Pressure alone knocks the surface layer off and leaves the roots, which is why a purely mechanical wash looks great in April and looks terrible again by July.

Soft washing solves that. A crew applies a sodium hypochlorite mix at low pressure, lets it dwell for several minutes, then rinses with garden-hose-level force. The growth dies rather than getting scraped, so the clean holds for two to three seasons instead of two to three months.

This matters for vinyl in particular. Missouri subdivisions built from the 1990s onward are full of vinyl siding that will chalk, streak, or take on water behind the courses if someone runs a turbo nozzle across it.

Ask any bidder what pressure they plan to use on your walls. If the answer is a number above 1,000 PSI for vinyl, keep calling.

Concrete, Driveways, and the Salt Problem

Flatwork is priced separately at $0.15 to $0.30 per square foot. A standard two-car driveway of about 600 square feet runs $90 to $180, and most companies set a minimum of $150 to $250 for a standalone concrete visit.

Missouri concrete carries three kinds of staining. There is the general gray biofilm, the orange rust bloom from sprinkler water and iron in the aggregate, and the white efflorescence that shows up after a hard winter of de-icing.

Rust removal is an add-on, usually $50 to $125 per stain area, because it takes an oxalic acid treatment rather than pressure. Efflorescence often needs an acidic masonry cleaner too, so expect a similar surcharge if your slab looks chalky.

Surface cleaner attachments are what separate a good concrete job from a bad one. A spinning surface cleaner leaves an even finish, while a wand leaves zebra stripes that will show for years.

Sealing after the wash is worth considering on newer pours. A penetrating sealer runs $0.50 to $1.25 per square foot and slows the salt damage that shortens driveway life across the northern half of the state.

Roof Streaks and What They Tell You

Those black vertical streaks on asphalt shingles are a cyanobacteria called gloeocapsa magma, and Missouri's humidity feeds it well. Roof cleaning here runs $0.20 to $0.55 per square foot of roof area, so a typical 1,800 square foot roof plane set costs $400 to $900.

No reputable company puts a pressure washer on shingles. The method is a low pressure chemical application that kills the growth and lets rain carry it off over the following weeks, which means your roof keeps improving for a month after the crew leaves.

Anyone quoting a roof "power wash" at high PSI is offering to strip your granules. That shortens shingle life and can void a manufacturer warranty outright.

Decks, Fences, and Anything Wood

Wood is the category where homeowners cause the most damage doing it themselves. Cedar and pine both go soft and fuzzy under too much pressure, and gouged wood cannot be sanded back out without removing a real amount of material.

A 300 square foot deck wash runs $150 to $300. Adding a stain or sealer pushes the project to $600 to $1,400 depending on how many balusters and rail sections have to be cut in by hand.

Fence washing prices by linear foot at $1.50 to $4.00. A 150 foot privacy fence is a $250 to $500 job, and cedar that has gone gray usually needs a brightener afterward to bring the tone back.

Missouri's wet spring makes the timing tricky on wood. Stain needs a dry window of two or three days after washing, so most companies schedule the wash and the finish as two separate visits a few days apart.

The Right Time of Year to Book

Late April through early June is the busiest stretch, right after oak and cedar pollen coats everything in the Ozarks and the river valleys. If you want that window, call in March.

September and October are the smarter booking months for most homes. Growth has peaked, temperatures still support chemical dwell time, and crews have open dates.

Winter work happens on the warm days. Above 40 degrees with no freeze in the forecast, a concrete or siding wash is fine, and some companies discount off-season by 10 to 20 percent to keep trucks moving.

Skip the deep freeze entirely. Water in a slab crack that freezes overnight does more harm than a dirty driveway ever will.

Sorting a $250 Quote From a $500 One

The gap between two bids on the same house usually comes down to four things: liability insurance, whether the crew is bringing its own water, what chemicals they use, and how much time they budget for dwell and rinse.

Ask for a certificate of insurance naming general liability of at least $1 million. Ask whether they carry a water tank or plan to use your spigot, since a residential hose bib in an older Missouri home may not keep up with a commercial machine.

Get the surface list in writing. A quote that says "house wash" without naming gutters, soffits, shutters, and downspout faces will turn into a change order on the day.

Comparing several local pressure washing companies side by side is the fastest way to spot the outlier bid, high or low. Two or three quotes on the same scope is enough for a job this size.

Common Questions About Pressure Washing Prices in Missouri

How often should a Missouri house be washed?

Every 18 to 24 months for most homes, and every 12 months if you have heavy tree cover or a north-facing wall that stays shaded. Homes near the Missouri and Mississippi river bottoms tend to fall on the shorter cycle.

Is renting a machine cheaper than hiring someone?

A weekend rental runs $75 to $120 plus chemicals and fuel, so the raw cost is lower than a $400 house wash. The catch is that consumer-grade rentals put out enough pressure to etch vinyl and gouge cedar, and siding repair starts around $500 a wall.

Does pressure washing use a lot of water?

A professional job uses roughly 4 to 8 gallons per minute for two to four hours, which is 500 to 1,900 gallons. That is comparable to a few loads of laundry per hour and rarely moves a Missouri water bill by more than a few dollars.

Should the gutters be included?

Exterior gutter faces are usually part of a house wash, but the black oxidation streaks on aluminum need a separate brightening treatment at $1.00 to $2.50 per linear foot. Interior gutter cleaning is a different service entirely.

Do I need to be home during the appointment?

Not usually, as long as outdoor spigots are accessible and windows are closed. Most Missouri crews finish an average house in two to four hours and text photos when the job is done.

Timing one wash for early fall and one concrete cleaning for spring covers the two conditions that drive dirt here, summer growth and winter salt. More Missouri home service cost guides are on our home services blog, along with seasonal maintenance checklists worth reading before you book.
