Professional House Washing in Hermitage, TN

Hermitage sits between the Stones River and Old Hickory Lake, and that geography shows up on your siding. The combination of waterfront humidity and the mature tree canopy that makes neighborhoods like Hermitage Hills and Tulip Grove so pleasant also keeps exterior walls damp and shaded — exactly the conditions where green algae and Gloeocapsa magma, the organism behind black streaking, grow fastest. If your north-facing wall is darker than the rest of the house, that is biology, not dirt.

We clean Hermitage homes with soft washing exclusively: a low-pressure application of biodegradable surfactant that kills the growth at the root, followed by a thorough garden-hose-pressure rinse. High pressure on siding forces water behind panels, cracks caulk, and voids vinyl manufacturer warranties — we never use it on a house. Because the organisms are killed rather than knocked off, the clean typically holds 12 to 18 months before regrowth begins.

Hermitage's housing stock ranges from established 1970s–90s brick ranches to newer infill construction, and each gets a tailored approach — gentler chemistry around aged mortar, careful rinse work on painted wood trim, and standard soft wash for vinyl. Soffits, fascia, window frames, and gutter exteriors are all included, and we pre-wet your landscaping before any solution goes on the wall.

We are a family-owned crew based ten minutes away in Mt. Juliet, and Hermitage is part of our home service area — no travel fees, no subcontractors. The person who quotes your house is the person who washes it.

Local FAQs
How often should Hermitage homes be washed?
Annually for most properties. Homes under heavy tree canopy or near the lake and river corridors regrow algae faster and benefit from a 12-month cycle; sunny, open lots can stretch to 18 months.
Is soft washing safe for older brick homes?
Yes — it is the right method for them. We use gentler chemistry and lower application rates around aged mortar, which high-pressure washing can erode permanently.
Do I need to be home during the wash?
No. We just need access to an outdoor spigot. Most Hermitage customers are at work during the job — we send photos when it is done.
Will the cleaning solution hurt my plants?
No. We pre-wet all landscaping before applying solution and rinse everything down afterward. The surfactants we use are biodegradable and applied at controlled rates.
