House Washing in Knoxville, TN — Soft Wash Done Right
Soft washing removes algae, mildew, and heavy spring pollen from vinyl, brick, and HardiePlank siding without high-pressure damage. Most Knoxville homes are cleaned in 2–4 hours.
When You Need House Washing
Green or black streaks on your siding — especially on north-facing walls — are the clearest sign. East Tennessee's humidity feeds algae and mildew year-round, and the growth is cumulative: a little each season until the exterior of a well-maintained home starts looking neglected. Heavy spring pollen from the Tennessee Valley's oak and maple canopy coats everything in a yellow-green film that doesn't wash off with rain. What looks purely cosmetic now can become a structural problem: algae holds moisture against siding and wood trim, and prolonged exposure accelerates paint failure, wood rot, and staining that gets harder to remove every season you wait.
How House Washing Works
Step 1 — Assess: We walk the property and note surface types — vinyl, brick, stucco, HardiePlank, wood — and identify any areas with heavy organic growth or staining.
Step 2 — Pre-wet and protect: Plants, landscaping beds, and any sensitive surfaces near the work area are thoroughly pre-wetted before any cleaning solution is applied.
Step 3 — Soft wash: Biodegradable cleaning solution is applied at low pressure, dwelling long enough to break down algae and mildew at the cellular level. The cleaning agent does the work — not the water pressure.
Step 4 — Rinse and walk: A low-pressure rinse (under 400 PSI) removes all loosened growth, solution, and pollen. We inspect with you before leaving and note anything that may need a follow-up pass.

What Does House Washing Cost in Knoxville?
House exterior washing in Knoxville runs $250–$550 for most homes. Single-story homes on the lower end; two-story homes with significant north-facing algae buildup or heavy spring pollen accumulation run higher. Large homes, heavily shaded lots, or properties that haven't been washed in several years may require additional time and sit toward the top of this range.

Frequently Asked Questions
How often should I have my house washed?
Most Knoxville homes benefit from annual exterior washing. Properties with heavy shade, north-facing walls, or significant tree canopy overhead — common in areas like Fountain City, Bearden, and Oak Ridge — tend to collect algae faster and may benefit from washing every 8–10 months.
Do I need to be home?
No. We just need access to a standard outdoor water spigot. Most customers head out and come home to a clean exterior. If we notice anything worth flagging during the job, we'll leave a note or give you a call.
Will soft washing damage my landscaping?
No — when done correctly. We pre-wet all plants and landscaping beds before applying any cleaning solution, and use biodegradable detergents that are safe for soil and plant life. This step is standard on every job, not optional.
Is soft washing the same as pressure washing?
No. Pressure washing uses high-pressure water (1,500–4,000 PSI) and is appropriate for concrete and brick hardscapes. Soft washing uses low pressure (under 400 PSI) combined with cleaning solution — it's the correct method for exterior siding, wood, and roofs. High-pressure washing on vinyl siding can crack seams, force water behind panels, and void manufacturer warranties.
