Pressure Washing Companies Serving the Asheville Area

Why everything turns green here

Asheville gets close to four feet of rain a year, and it lands on houses sitting under a hardwood canopy, on lots that don’t get sun from every side. A north-facing wall in Kenilworth or a shaded deck in Montford can stay damp for days after a storm. Algae, mildew, moss, and lichen need exactly that, and they grow on siding, decks, concrete, and roofs here faster than the national advice assumes.

The part that matters for your house: what’s growing on it is alive. It isn’t dirt that rinses off. Algae holds moisture against a surface, mildew works into paint, moss lifts shingles, and lichen roots into whatever it’s on. Left long enough, cleaning stops being cosmetic and starts being maintenance you skipped.

Pressure or chemistry: which surface gets which

The single most useful thing to know before you call anyone is that “pressure washing” is two different jobs, and the wrong one on the wrong surface does damage you can’t undo.

Soft washing means low pressure, about what a garden hose delivers, and a cleaning solution that does the work instead. The solution is usually diluted sodium hypochlorite, the same chemistry as household bleach, with a surfactant to help it cling and rinse. It kills the growth rather than shearing it off, which is why a soft-washed wall stays clean longer than a pressure-washed one.

Precision Pro Wash and WNC Pressure Washing both spell out this distinction on their own sites in close to these terms, which is a good sign. A company that describes every job as pressure washing, with one machine and one setting, is the one to be careful with.

The roof is where mistakes get expensive

The black streaks on a shingle roof are a cyanobacteria called Gloeocapsa magma, and shaded WNC roofs are close to ideal for it. It’s ugly, it holds heat and moisture, and it comes back within a year of any cleaning that only knocked it loose rather than killing it.

It also can’t be pressure washed. The Asphalt Roofing Manufacturers Association recommends a bleach-and-water solution applied gently and rinsed at low pressure, and specifically warns against pressure washers, because the pressure that removes the algae also removes the granules that protect the asphalt from sun. Most shingle manufacturers treat pressure washing as damage you caused, not a defect they’ll cover.

So ask any company specifically how they’ll clean your roof, and ask what they’ll do about the runoff, since the solution that kills algae also kills the boxwoods under the drip line. Precision Pro Wash puts a five-year spot-free warranty on its roof cleaning, which is a useful benchmark to hold other quotes against: a company confident it has killed the growth can afford to stand behind the result.

If a roof is old enough that granule loss is already visible in the gutters, cleaning is the wrong conversation. That’s a roofing contractor question.

That judgment is also why the better companies won’t quote a roof off a photo. We asked Benjamin Stuck, co-owner of Precision Pro Wash, how he decides a roof is past the point where cleaning makes sense:

“We only do in-person estimates and this is a big reason why. While our estimators don’t get on the roof for insurance reasons, if a roof has a lot of damage such as missing shingles, lack of aggregate, various nail pops or active leaks, we would recommend the client have the roof repaired or replaced prior to cleaning.”

Worth knowing what he’s looking for, because you can spot most of it from the ground with a pair of binoculars: bare patches where the granules have worn off, shingles lifted or missing after a storm, nail heads backing out through the surface, and any stain on a ceiling inside.

He also put a number most homeowners get backwards in its place:

“Most shingle manufacturers sell a shingle with an expected lifespan — examples would be a 15 year shingle, 25 year shingle, etc. Think of this as an ‘average’ life expectancy. This ‘rating,’ however, does NOT mean 15 year shingles must be replaced at 15 years. Keeping the shingles clean during the life of the roof will extend their life assuming no catastrophic damage such as significant hail, tree strikes, etc.”

So the rating on the wrapper is an average, not an expiration date, and which side of that average your roof lands on has a lot to do with whether anything has been living on it for a decade. Under this much shade, that’s the argument for cleaning a sound roof and for not cleaning a failing one.

Wash before you paint or stain

Several of the businesses on this page are painters, and that isn’t a filing error. A repaint fails from the surface underneath it, and paint over mildew or chalked pigment lets go early no matter what’s in the can. High Definition Pressure Washing, Perfect Color Painting, and Red Beard Painting and Handyman all offer washing alongside exterior painting or deck staining for that reason. One crew, one schedule, and nobody arguing about whose prep it was when something peels.

Two things to plan around:

The wood has to dry. A deck that was washed needs a couple of dry days before stain goes on, or the finish traps moisture and fails from below. In a wet Asheville spring that can mean rescheduling, and a company that stains the afternoon after it washes is rushing.

Old paint is its own problem. If the house predates 1978 and the paint is peeling, a wash strong enough to strip it scatters chips into the beds, and the painter’s lead-safe rules apply the moment paint comes off the wall. Ask how they’ll contain it, or have a lead-certified painter handle the prep.

When to book

Pollen sets the calendar here. The pine pollen comes down in April and coats every horizontal surface in yellow, and a house washed in early April looks like it wasn’t washed by the end of the month. Late April through May, once it settles, is the busy season and the sensible one.

Fall is the second window, after the leaves are down and before the first hard freeze, since nobody can wash in freezing weather. It’s also when decks get cleaned ahead of staining and when houses get a wash before going on the market.

Book earlier than you think for either. The good companies here fill up, and the ones with open calendars in the second week of May are open for a reason.

Where the water goes

Wash water carries whatever came off the house plus whatever went on it, and in the city that water has two places to go: into your yard, or into a storm drain that runs straight to the French Broad or the Swannanoa without passing through a treatment plant. Cleaning solution isn’t supposed to go down that drain.

A careful crew handles this without being asked. They pre-wet your plants and beds so the solution can’t soak in, rinse them during and after the wash, cover anything delicate, and keep runoff on the lawn where the soil neutralizes it. Kospa Clean guarantees property and plant protection on its work, which is the right posture. If you have a vegetable garden, a koi pond, or a rain barrel below the gutters, mention it when you book, not when the truck arrives.

No license to check, so insurance is the credential

North Carolina doesn’t license pressure washing the way it licenses electricians or plumbers. There’s no state board and no number to look up, which means anyone with a machine and a truck can advertise, and in a town this size plenty do.

That puts the weight on two things. The first is a certificate of general liability insurance, sent to you before the work starts, not described over the phone. The most common damage in this trade is water driven behind siding and into a wall, and it can take months to show up. Ask what happens if it does. The second is a body of work: before-and-after photos of local jobs, and reviews that describe the specific surface you’re having cleaned.

The companies here have been at it a while. Precision Pro Wash has worked out of Crayton Road since 2006 and carries a million dollars in coverage. Kospa Clean has run out of Gashes Creek Road for more than fifteen years. WNC Pressure Washing, veteran-owned and based in Maggie Valley, covers Buncombe and Haywood and handles the stain work most crews skip, like rust, oxidation, and solar panels.

Commercial washing

The commercial side of this trade is a different job with different equipment. Restaurant dumpster pads and brewery patios need hot water for grease. Parking decks and HOA sidewalks are volume work with a surface cleaner rather than a wand. Storefronts downtown and along Haywood Road have sidewalks, awnings, and gum to deal with, and a schedule that has to work around the doors being open.

Precision Pro Wash, WNC Pressure Washing, and Perfect Color Painting all list commercial work. Ask about hot water if grease is involved, ask about after-hours scheduling, and ask where the runoff goes, because downtown that answer is a storm drain unless the crew has a plan for it.

How companies get listed here

Every business on this page is independent and based in Western North Carolina. We generally leave out national franchises and chains, not because they can’t do the work, but because there are already plenty of places to find them.

Listings are free. Businesses can claim their listing to keep hours, services, and contact details current, and a small number pay for a featured slot, which moves them up the page and is labeled where it appears. Nothing else about the order is for sale. We don’t sell your contact information, and we don’t charge these companies per lead, so nobody here is paying for the privilege of calling you.

If your gutters are part of what needs attention, several of these companies clean them on the same visit, and the gutter cleaning page covers how often that actually needs doing under this much tree cover.

Frequently asked questions

• Is power washing the same as pressure washing?

  Close enough that the companies on this page use the terms interchangeably. Strictly, power washing means the water is heated and pressure washing means it isn't. Hot water matters for grease, gum, and oil, which is why it shows up on restaurant pads and commercial jobs. For a house, a driveway, or a deck, the question that actually matters is whether the job needs pressure at all or a low-pressure soft wash, and any company worth hiring will answer that before you ask.

• How often should a house be washed in Asheville?

  For most homes here, every year or two, and the shaded north side sets the schedule. Algae and mildew grow on any wall that stays damp, and under a mature hardwood canopy that can be most of the house. A sunny, open lot can go longer. Since the growth is a living organism rather than dirt, waiting until it's dark green means it has been holding moisture against the siding for a while.

• Can you pressure wash an asphalt shingle roof?

  No. The black streaks on shingles are a living algae, and the pressure it takes to blast them off also strips the granules that protect the shingle from sun. The asphalt roofing industry's own guidance is a bleach solution applied gently and rinsed at low pressure, which is what soft washing is. Most shingle warranties treat pressure washing as damage you caused. Ask any company specifically how they'll clean your roof, and if the answer involves a pressure wand, keep looking.

• How much does pressure washing cost in Asheville?

  It depends on what's being washed more than how big the house is. Square footage, number of stories, how steep the lot is, how heavy the growth is, and whether the roof, deck, or driveway are part of the job all move the number, and a roof soft wash is usually priced separately from a house wash. Get two or three quotes and confirm they cover the same surfaces, or you're comparing different jobs. Most companies here give free estimates.

• Will pressure washing damage my siding or my plants?

  It can do both if it's done wrong, and both are avoidable. High pressure forces water behind vinyl and lap siding and into the wall, which is the most common damage claim in this trade, so siding should be soft washed. The cleaning solution is diluted bleach plus a surfactant, and it will burn foliage if it isn't managed. A careful crew pre-wets your beds, rinses them during and after, and covers anything delicate. Ask how they protect plants before you book.

• When is the best time of year to pressure wash in Asheville?

  Late April through May, once the pine pollen has finished, is the most popular window and for good reason. Wash before the pollen ends and you'll be looking at a yellow film again in a week. Fall is the other good time, after the leaves are down and before the first freeze, since companies can't wash in freezing weather. If a deck is being stained or a house is being painted, the wash needs a couple of dry days before the finish goes on, so plan the two jobs together.

• Do pressure washing companies need a license in North Carolina?

  No. North Carolina doesn't license pressure washing the way it licenses electricians or plumbers, so there's no state board to check. That makes insurance the credential. Ask for a certificate of general liability insurance before anyone sets up at your house, and ask what happens if water gets behind the siding or a window seal fails. A company carrying real coverage will send the certificate without hesitating.
