House Washing in Chattanooga, TN

Types of house washing we offer

Every siding material takes its own mix strength and its own rinse. These are the house washing jobs we quote most often around Hamilton County.

• Vinyl siding cleaning

  Vinyl is the siding we wash most and the easiest to hurt with pressure, because water forced up behind the laps gets trapped against the sheathing. We spray a 0.5-2% sodium hypochlorite mix, let it dwell, and rinse low. Most vinyl manufacturers back the color for 50 years against noticeable fading, and a gentle clean keeps that finish intact.

• Algae and mildew removal on siding

  The green film on north walls is algae, and the gray or black speckling is mildew. Chattanooga gets 55 inches of rain a year and averages about 72% humidity, so shaded walls stay damp enough to regrow both every season. Soft washing kills the growth instead of scraping the top layer off, which is why the wall stays clean far longer than after a plain rinse.

• Brick cleaning

  Brick house washing means detergent and a low-pressure rinse, never a turbo nozzle that chews mortar joints. About 18.4% of Chattanooga homes were built before 1950, and that older, softer brick needs the care. St. Elmo's historic guidelines cap masonry cleaning at 600 PSI, and we stay well under it. White efflorescence gets its own cleaner and a separate rinse.

• Stucco and EIFS cleaning

  Stucco and EIFS (synthetic stucco) soak up water and crack under a pressure tip, so we clean them the way ARMA tells roofers to clean asphalt: chemical first, force never. A surfactant keeps the mix on textured finishes long enough to work, and the rinse comes through a wide soft wash tip. Mildew lines under window sills come off without gouging the coat.

• Fiber cement siding cleaning

  Fiber cement lap siding and trim hold paint well, and paint is the first thing a pressure washer strips. Our soft wash lifts chalky film, pollen and mildew from fiber cement at low pressure. Chattanooga ranks #26 of 100 metros in AAFA's 2026 Allergy Capitals report, so the yellow coat that settles on siding every spring is a regular April call for us.

• Painted wood siding and trim

  Painted cedar, pine lap siding and wood trim on older Chattanooga homes get our mildest mix, at the low end of 0.5-2% SH, and a rinse that won't raise grain or peel sound paint. If paint is already failing, we point it out before we start, since a wash will show it. We clean and don't paint, so you'll know exactly where a painter is needed.

• Soffit, fascia and porch ceiling cleaning

  Soffits, fascia, porch ceilings and the underside of overhangs collect cobwebs, mud dauber nests and mildew where rain never reaches. We soft wash them with every house wash at no extra charge, along with shutters, front doors, garage doors and foundation walls. Ground-floor windows get a final clean-water rinse so the mix never dries on the glass.

• Red clay and rust stain removal

  Southern red clay is an Ultisol colored by iron oxide, which is why the splash-back along the bottom courses of siding stains like rust. Bleach won't touch it. After the house wash we apply an oxalic acid based rust and clay cleaner to foundation walls, siding and steps, and we quote it as its own line before any work starts.

Soft wash vs pressure washing: which is right for siding?

Soft washing is right for almost all siding. It uses a cleaning solution at low pressure to kill algae, mildew and lichen, then rinses gently. Pressure washing relies on force alone, up to 4,000 PSI from a pro rig, which strips the stain but leaves the roots behind and can crack vinyl, etch brick and push water behind laps.

The chemistry is what makes the difference. Sodium hypochlorite, the active ingredient in bleach, kills the organisms. Household bleach runs 3-8% SH, and our house wash mix sits at 0.5-2%, carried by a surfactant so it clings to vinyl and brick instead of sheeting into flower beds. ARMA, the shingle makers' trade group, tells homeowners never to put a power washer on an asphalt roof, and the same logic holds for siding.

Pressure still has a job at your house. Concrete and other hard flatwork take a surface cleaner at full pressure, which is how we handle driveways and walkways. On siding, our 4.0 GPM rig switches to soft wash tips and moves about 240 gallons of rinse water an hour at low force, enough to flush the mix away without lifting a single panel.
