Residential Pressure Washing & Soft Washing Services
The method follows the surface: soft wash for siding, roofs and painted wood, surface cleaners and measured pressure for concrete and stone.
House Soft Washing
A house soft wash sprays a 0.5-2% sodium hypochlorite mix with surfactant at garden-hose pressure, lets it dwell, then rinses from the ground. It kills green algae, mildew and pollen film instead of blasting at them, which matters in a city that gets 55 inches of rain a year. Soffits, fascia, porch ceilings and shutters are washed on the same visit.
Vinyl Siding Cleaning
Vinyl siding is built to last, and most manufacturers back it with 50-year warranties against noticeable fading. High pressure is what shortens that life, forcing water behind the laps and into the wall cavity. We clean vinyl at low pressure with a wide 40-degree rinse, taking the green film off north walls and the gray streaks that run down from window corners.
Brick Cleaning
Brick holds mildew in its pores and mortar joints, and older brick is soft. About 18.4% of Chattanooga homes were built before 1950, so the Chattanooga Washing team cleans brick with detergent and dwell time rather than force. St. Elmo's historic design guidelines cap masonry cleaning at 600 psi, and that is a sensible ceiling for any pre-war brick home.
Roof Cleaning & Black Streak Removal
Black streaks on shingles are Gloeocapsa magma, the cyanobacterium the roofing industry names as the main cause of roof discoloration. ARMA says never to power wash or brush asphalt shingles, so our roof cleaning is a no-pressure soft wash with a 4-6% mix left on for 15 to 20 minutes and gently rinsed. It also kills moss and lichen on shaded slopes.
Driveway Pressure Washing
Concrete is one surface that can take real pressure. Our crews run 4,000 PSI machines through 20 and 24 inch rotary surface cleaners, which clean in even passes without the stripes a hand wand leaves behind. Shaded driveways go dark with mildew within a year or two, and driveway cleaning starts at $149 for a standard two-car slab.
Concrete & Sidewalk Cleaning
Front walks, steps, curbs, carport slabs and retaining wall caps grow the same algae as the driveway but get left off most quotes. After the surface cleaner pass we post-treat sidewalks with a 2-4% sodium hypochlorite mix, which kills the green film sitting in the broom-finish texture. HomeAdvisor puts walkway and patio concrete at $0.20 to $0.40 per sq ft.
Paver & Patio Cleaning
Paver patios and walkways need less pressure than poured concrete, because a hard pass pulls the joint sand out and lets weeds back in. We clean pavers, flagstone and stamped concrete on a low surface cleaner setting with a soft wash post-treatment. The white powder on newer pavers is efflorescence, salts carried out of the stone by water, and it needs its own treatment.
Deck Cleaning
Pressure-treated pine, cedar and composite decks go gray and slick under Chattanooga's 71.9% average humidity. We wash decks with a 25-degree fan tip held well back from the boards, plus a cleaner that lifts mildew and the brown tannin stains left by fallen leaves. The wood comes out clean and ready for your own stain or sealer, which we do not apply.
Fence Cleaning
Wood privacy fences, vinyl picket fences and split rail all grow mildew on the side that faces away from the sun. Our Chattanooga wash crew soft washes vinyl and keeps pressure low on wood, cleaning both faces of the fence where the neighbor allows access. HomeAdvisor's national range for fence washing is $150 to $300, a fair guide for a typical backyard run.
Gutter Cleaning & Brightening
Gutter cleaning clears leaves, pine needles and seed pods by hand and flushes every downspout, and twice a year is the local baseline under oaks and maples. Brightening is the outside job: the black tiger stripes on aluminum gutter faces will not wash off in the rain, so we remove them with a gutter-safe cleaner and a soft brush.
Window Washing
Window washing comes after the siding is clean, otherwise runoff from the house wash spots the fresh glass. We clean frames, sills and screens, finish the glass by hand and rinse with a wide 40-degree tip that is safe for seals. Spring pollen is the usual reason to book, and Chattanooga ranks 26th of 100 metros in AAFA's 2026 Allergy Capitals report.
Rust, Red Clay & Oil Stain Removal
Red clay splash-back is iron oxide from the region's Ultisol soils, so it stains siding and concrete like rust and shrugs off bleach. We treat clay, irrigation rust and fertilizer marks with an oxalic acid cleaner that binds iron, and lift oil and grease from driveways with a degreaser and hot water. Stain treatment adds $50 to $200 on concrete.
Specialty Exterior Cleaning Services
Jobs that fall outside a standard house or driveway wash, priced once we have seen the surface.
Pool Deck Cleaning
Pool decks grow slippery algae in shaded corners and collect sunscreen and leaf tannins around the coping. We clean concrete, travertine and paver pool decks with a surface cleaner and a mild post-treatment, keeping rinse water out of the pool and away from the filter. HomeAdvisor puts pool deck cleaning at $0.20 to $0.40 per sq ft, and ours start at $99.
Stone & Retaining Wall Cleaning
Sandstone walls, fieldstone chimneys and block retaining walls stay damp after rain, so they carry moss, lichen and black algae for years. About 90% of known lichens have an algal partner, which is why a soft wash mix kills them where scrubbing only smears them. We clean stone at low pressure and let the dead lichen loosen and rinse off over the next few rains.
Porch, Soffit & Screen Room Washing
Porch ceilings, soffits and screened rooms gather cobwebs, wasp nests, pollen and the mildew that grows where sun never reaches. We wash painted beadboard and vinyl soffit at low pressure with a 0.5-2% mix, rinse screens gently so the mesh stays tight, and clean porch floors last. Most covered porches are added to a house wash rather than booked on their own.
Awning Cleaning
Fabric and metal awnings over homes, restaurants and storefronts turn green on top and gray underneath. We soft wash canvas and acrylic awnings at low pressure so the stitching and coatings hold up, and clean metal awnings and canopies the same way as a metal roof. A storefront awning can be washed on the same visit as the sidewalk below it.
Graffiti Removal
Spray paint on brick, block or concrete needs a remover matched to both the paint and the surface, followed by a hot water rinse. We test a small patch first, because porous brick can keep a ghost image if the wrong product goes on. Graffiti removal on walls, dumpster enclosures and retaining walls starts at about $150 per visit.
New Construction Cleanup
Builders and new homeowners call us for the final exterior clean: mortar splatter on brick, mud on driveways, red clay tracked onto walks and paint flecks on windows. New brick often shows white efflorescence, salts drawn to the face by water, and we clean it separately from the mortar haze. Siding, flatwork and glass are done in one visit before the closing walkthrough.
Commercial Pressure Washing in Chattanooga
Commercial pressure washing starts at $0.10 per sq ft for flat concrete, with work scheduled before opening, after close or on weekends. Wash water is kept out of storm drains, in line with Chattanooga's stormwater rules and the EPA's NPDES program.
Restaurants & Drive-Thrus
Grease on dumpster pads, drive-thru lanes and patio dining areas needs hot water, because heat emulsifies oil that cold water only spreads around. We degrease pads, wash stained walkways and soft wash the building face after closing time, so service never stops and the morning crew opens to clean concrete.
Storefronts & Retail Centers
Sidewalks, entries, gum-spotted walkways and storefront glass are what customers see first. Our crews clean retail strips, signage and awnings early in the morning, block the nearest storm inlet and send the wash water to landscaping instead of the street, and multi-tenant centers can be split into sections.
Office Buildings
Office exteriors in EIFS, brick, glass and metal panel get a low-pressure soft wash that leaves the finish intact. Hi-lift equipment reaches buildings up to 10 stories, so tall walls are cleaned without scaffolding, and commercial window washing can be booked on the same lift days.
Apartment & HOA Communities
Tennessee has about 5,500 community associations covering 315,000 homes, and most set standards for siding, walks and amenities. We wash buildings, breezeways, stairwells, pool decks and entrance signs on a rotating schedule, under a service agreement that sets every visit for the year.
Parking Garages & Lots
Parking decks collect oil drips, tire marks and stairwell grime that make a property look neglected. We clean decks, ramps, stairwells and surface lots with wide surface cleaners and hot water on the oil, at night or on weekends, and plan the job level by level so part of the garage stays open.
Industrial Sites & Fleets
Warehouses, loading docks, heavy equipment and fleet trucks come clean with hot water and degreasers that cut road film and hydraulic oil. Fleet washing can run on a weekly or monthly route at your own lot, so vehicles stay on the job and branded trucks stay presentable.
Why We're the Best Pressure Washing Company in Chattanooga
Plenty of pressure washing companies around Chattanooga own a machine and a wand. What sets a crew apart is matching the method to the surface, writing the price down first and standing behind the result.
Soft Washing That Protects Chattanooga Siding and Roofs
High pressure stays on concrete and stone. Siding, painted wood and shingles get a 12-volt soft wash pump and biodegradable, low-odor detergents, the bleach-and-water approach ARMA recommends for roof algae, so paint and siding laps are left alone.
A 12-Month Mold & Mildew Free House Wash Guarantee
Every house soft wash is guaranteed mold and mildew free for 12 months. If growth returns on the washed walls inside that year, the Chattanooga Washing team comes back and treats it. That counts in a valley with about 123 days of measurable rain a year and 77% average humidity in September.

What Chattanooga Customers Say About Our Pressure Washing
- Karen M.September 2026
Our vinyl siding in Hixson had green film on every north wall. Chattanooga Washing soft washed the house in one morning and soaked my hydrangeas first, and they are fine. The price matched the estimate to the dollar.
- David R.August 2026
One roofer told us to replace our streaked roof on Signal Mountain. These guys soft washed it instead, no pressure on the shingles. The black streaks were gone after the next rain, and they cleared the gutters while they were up there.
- Tasha W.September 2026
Red clay from a landscaping project stained half our driveway in East Ridge. Their clay treatment got most of it out and the concrete looks new. One faint spot remains, but they warned me upfront. Fair price, right on time.
- Mike P.August 2026
Booked gutter cleaning for our two-story in Ooltewah after the downspouts overflowed. They hand cleaned everything, flushed the downspouts and brightened the black stripes off the front gutters. Professional from the first text to the invoice.
- Linda H.September 2026
I manage a townhome HOA in East Brainerd and hired Chattanooga Washing Co. for the buildings, breezeways and pool deck. They worked in sections so residents always had a way in and sent photos of every building. We signed a service agreement for next year.
- Ben S.August 2026
Our deck in Soddy-Daisy was gray and slippery after years under the trees. The crew washed it at low pressure with no fuzzing or gouges, and I stained it that weekend. The stairs took longer than planned, but the price stayed the same.

Pressure Washing FAQs for Chattanooga Homeowners
Is it cheaper to rent a pressure washer or hire a pressure washing company?
Renting looks cheaper at $35 to $175 a day, but rental machines cannot soft wash, and the wrong nozzle on siding or shingles causes damage that costs far more than a $249 house wash. A professional crew brings 4,000 PSI concrete equipment and a separate soft wash rig.
How often does a Chattanooga home need exterior cleaning?
Plan on a house wash every year, gutter cleaning twice a year, driveway cleaning every one to two years and a roof soft wash every two to five years. Shaded lots need the shorter end of each range, because 55 inches of yearly rain keeps north walls and slopes damp.
What is the difference between soft washing and pressure washing?
Soft washing cleans with chemistry: a diluted sodium hypochlorite and surfactant mix applied at very low pressure that kills algae, mildew and lichen, then a gentle rinse. Pressure washing cleans with force, usually 3,000 to 4,000 PSI through a surface cleaner, and belongs on concrete, pavers and stone, not siding or shingles.
Can black streaks on my roof be removed without damaging it?
Yes. Black streaks are colonies of Gloeocapsa magma, an airborne cyanobacterium that thrives in warm, humid regions, not dirt or soot. A roof soft wash with a 4-6% sodium hypochlorite mix kills it without any pressure on the shingles, and in Chattanooga the results typically last about 2 to 3 years.
Will the cleaning mix hurt my lawn, garden or pets?
Not when the job is prepped properly. Plants and grass are soaked with plain water before the wash and rinsed again afterward to dilute any overspray, and the detergents are biodegradable and low-odor. Keep pets indoors until the rinsed surfaces have dried.
Do I need to be home for pressure washing?
No. Most customers are at work during the visit. The crew needs an outdoor water spigot, unlocked gates, closed windows and cars moved off any concrete being cleaned. Before and after photos are sent when the job is finished, so you can check the work from your phone.
Can you clean my house before an HOA deadline?
Yes. Send a photo of the violation notice and the house, and we will quote in writing and book the wash before your deadline whenever the schedule allows. Siding, walks and the driveway can be done in one visit, and the before and after photos can go straight to your HOA.
When is the best time of year for pressure washing in Chattanooga?
Late spring suits house washing, after the oak and pine pollen has dropped, since Chattanooga ranks 26th of 100 U.S. metros for allergies. Roofs clean best in late winter or spring, after the December to March rainy months, and gutters in spring and again after the fall leaf drop.
