House Washing • Old Hickory, TN

Professional House Washing in Old Hickory, TN

Old Hickory is one of Middle Tennessee's most distinctive communities — a historic DuPont company village of 1920s homes alongside lakefront properties on Old Hickory Lake. Both come with cleaning challenges that generic pressure washing gets wrong. The village's older homes carry painted wood siding, original trim, and aged brick that high pressure damages permanently. The lakefront's constant humidity feeds algae and mildew faster than almost anywhere else we service.

Soft washing solves both. Our low-pressure process — about the strength of a garden hose — lets biodegradable surfactants do the cleaning chemically, killing mold, algae, and mildew at the root without lifting paint, eroding mortar, or forcing water behind siding. It is the only method we use on houses, and it is the method siding and paint manufacturers specify.

On older Old Hickory homes we adjust dilution and dwell times for painted and original wood surfaces, and rinse with deliberate care around historic trim. On newer construction and lakeside homes we treat the heavy north-side and water-facing growth that lake humidity produces. Soffits, fascia, window frames, and gutter exteriors are included on every wash.

Frequently Asked Questions

Straight answers about our pressure washing and soft washing services in Middle Tennessee.

Local FAQs
Is soft washing safe for my older Old Hickory home?
Yes — it is the only safe professional method for painted wood, original trim, and aged brick. We adjust our chemistry for older surfaces and never put high pressure on a house.
Why does my lake-facing wall get dirty so fast?
Humidity off Old Hickory Lake keeps that wall damp longer each day, which accelerates algae and mildew growth. Soft washing kills the growth at the root, so lakefront walls stay clean 12+ months instead of regrowing in a season.
How long does a house wash take?
Most Old Hickory homes take 2–3 hours from setup to final rinse. Larger lakefront homes or heavy buildup can add an hour.
Do I need to be home?
No — we just need access to an outdoor spigot with windows and doors closed. We send completion photos when the job is done.
