Pressure Washing in St. Louis, MO

Your driveway is stained. Your patio has a green film. Your sidewalk hasn't looked clean since last spring. That's a pressure washing job, and it's one we handle the right way, every time.

St. Louis weather is hard on concrete and flatwork all year. Between spring pollen, summer grime, and winter salt, most properties in this metro need a real pressure wash at least once a year to stay ahead of it.

Professional Pressure Washing Services in St. Louis

We run high-pressure cleaning on driveways, sidewalks, patios, and pool decks across St. Louis City, St. Louis County, and St. Charles. If it's concrete, brick pavers, or another hard flatwork surface, we can get it clean fast.

Every job starts with a walk of the property. We check the surface material, the level of buildup, and anything nearby that needs protecting before a single nozzle turns on.

We show up with commercial-grade equipment, not a rented unit from the hardware store. That means consistent pressure, faster jobs, and a cleaner finish than a DIY pass usually gets you. Landscaping and outdoor furniture near the work area get moved or protected before we start, and we walk the finished surface with you before we call it done.

Driveway & Concrete Pressure Washing

Concrete can take real pressure, and that's exactly what it needs. Commercial-grade surface cleaners built for concrete typically run around 3,000 PSI, enough force to lift oil stains, tire marks, tree sap, and years of ground-in dirt without damaging the surface underneath.

That same pressure is exactly wrong for other materials. Vinyl siding, wood trim, and asphalt shingles were never built to take that kind of direct hit. On concrete, that force cleans. On siding, it strips paint and drives water behind panels it was never meant to get behind. On a roof, it can crack or dislodge shingles outright.

This is why equipment choice matters more than most homeowners realize. The pressure that makes your driveway look brand new is the same pressure that can cost you a paint job or a shingle replacement if it's aimed at the wrong surface. We calibrate every job to the material in front of us, and concrete gets the full force it can handle.

Stains respond differently too. Oil and rust need targeted pressure and dwell time. Algae film on a shaded patio lifts faster with a pre-treatment pass first. We adjust technique surface by surface, not a single setting for the whole property.

Sealed and unsealed concrete need different handling as well. A sealed driveway can usually take a faster, more direct pass. Bare or older concrete needs a slower approach so we don't etch or pit the surface while lifting the stains. Brick pavers get their own technique too, since the joints between pavers can wash out under the wrong pressure and angle.

None of this is guesswork on our end. It's the difference between a driveway that looks new and one that looks scarred, and it's why we don't hand this job to whoever's cheapest that week.

Nozzle choice matters just as much as pressure. A tight, focused tip concentrates force into a small area and works fast on heavy stains, but held too long in one spot it can etch a line into concrete. A wider fan tip spreads that same pressure out for even, general cleaning. We switch between them depending on what we're standing on, not on habit.

Commercial Pressure Washing & Flatwork

Parking lots, sidewalks, loading areas, and commercial patios all fall under the same service. Property managers and business owners across St. Louis City, St. Louis County, and St. Charles call us when curb appeal starts affecting how a property looks to tenants, customers, or buyers. A stained entrance or an oil-streaked lot sends a message before anyone reads your sign.

Commercial flatwork sees more traffic than a residential driveway, which means more oil, more tire residue, and more grime buildup over a season. We scale equipment and crew size to the square footage, whether that's a single storefront entrance or a full parking lot.

We can schedule commercial jobs early morning, evenings, or weekends to stay out of the way of business hours and customer traffic. Recurring service is available too, so a property doesn't slide back into needing a full reset every few months. A lot of commercial clients set up a quarterly or seasonal pass and stop thinking about it.

Best Time of Year to Pressure Wash Concrete in Missouri

Spring is peak season here for a reason. Missouri's tree pollen leaves a yellow-green film across driveways and sidewalks every year, and it's one of the most common calls we get once the trees bloom.

Winter leaves its own residue. Road salt gets tracked onto driveways and walkways all season, and it sits there drying out concrete and leaving a dull, chalky look by the time spring rolls around. A late-winter or early-spring pressure wash clears that out before it does more damage.

Selling your home or hosting an event? Timing matters there too. A clean driveway and walkway make a real first impression, and we recommend booking a week or two out from any listing photos or big gathering so everything looks its best on the day that counts.

Summer humidity brings its own buildup on shaded patios and pool decks, where algae and mildew take hold fast in the heat. And fall means leaves and tree debris staining concrete before winter sets in for good. Realistically, a well-used St. Louis property benefits from a pressure wash at least once a year, sometimes twice if it's heavily shaded or gets a lot of foot traffic.

What We Don't Pressure Wash (and Why)

We don't run high pressure on siding, stucco, brick exteriors, or roofing. Ever. That pressure strips paint, forces water where it doesn't belong, and can crack shingles outright. Those surfaces get soft washed instead, a low-pressure method built to clean without the damage. If you want the full breakdown of power washing versus soft washing and which surfaces need which, see our power washing page.

How Much Does Pressure Washing Cost in St. Louis?

Cost depends on square footage, surface condition, and how much staining you're dealing with. A driveway with light dirt is a quicker job than one with years of oil and rust buildup.

We don't post flat numbers here because every property is different, and a generic price doesn't tell you much. For a real look at what drives pricing on the exterior cleaning side of our business, read how much house washing actually costs.
