Residential Exterior Cleaning
Soft House Washing That Brings Your Siding Back to Life
Our low-pressure soft wash system safely lifts dirt, algae, mildew, and pollen from vinyl, brick, stucco, Hardie board, and painted siding.
What it is
House Washing, explained simply.
House washing is not the same as blasting your siding with a pressure washer. We use a soft wash process: a gentle rinse combined with professional-grade cleaning solutions that break down organic growth at the root. The result is siding that looks deep-clean — not just rinsed — without forcing water behind panels, under trim, or into electrical fixtures.

A closer look
Everything worth knowing.
House washing in East Tennessee is not a luxury — it is preventive maintenance. The Tennessee Valley's humid summers, shaded tree cover, and pollen-heavy springs create the perfect environment for algae, mildew, and organic film to settle into vinyl, brick, stucco, fiber cement, and painted wood siding. Left alone, that growth eats into surface coatings, traps moisture against the wall system, and shaves years off the life of paint and caulking.
Admiral's soft wash process was designed specifically for the materials and weather we see across Knox, Blount, Loudon, Monroe, and Anderson counties. Instead of relying on raw water pressure, we use a low-pressure delivery system combined with a professional-grade, biodegradable cleaning solution that breaks the algae bond at the root. The siding looks deep-clean the same day, and stays clean dramatically longer than a simple rinse.
Pressure washing — high PSI, narrow tips, contractor-grade wands — has its place on hard concrete. It does not belong against your home. Used on siding, high pressure forces water behind vinyl panels and under trim, peels paint, etches stucco, splinters cedar, and voids fiber-cement warranties. If a company is hitting your walls with a 0° or 15° tip, they are gambling with your wall system.
DIY vs. Professional
When DIY makes sense — and when it doesn't.
The DIY reality
- Garden-hose attachments lack the dwell time and dilution control to kill algae at the root.
- Box-store pressure washers (2,500–3,000 PSI) are above the safe range for vinyl and Hardie.
- Bleach mixed by eye damages landscaping and can streak siding if not pre-wet and rinsed correctly.
- Ladders + wands = the #1 source of weekend pressure-washing injuries.
What a pro brings
- Calibrated soft-wash systems deliver consistent dilution at the nozzle, not in a bucket.
- Two-story reach without ladders thanks to surfactant-stabilized application.
- Pre-wet, rinse, and post-rinse protocols protect landscaping you've invested years in.
- Insurance and trained crews — if something goes wrong, it is not on your homeowner's policy.
For a small porch column or a one-story shed, DIY is fine. For an entire home, a professional soft wash is almost always cheaper than a single repair caused by the wrong method.
Surfaces & materials
We tune the method to the material.
Vinyl siding
Most common siding in East TN subdivisions. Brittle in winter, prone to chalking. Requires low pressure and gentle dwell time — never a 0° tip.
Fiber cement (Hardie)
Durable but the painted surface can be stripped by high pressure. James Hardie explicitly recommends soft washing under 1,500 PSI.
Brick & mortar
Looks indestructible — isn't. High pressure blows out mortar joints. We use solution + gentle rinse to lift efflorescence and algae.
Stucco & EIFS
Porous and easy to damage. Soft washing only; high PSI causes pitting that requires patching and repainting.
Cedar & painted wood
Soft washing preserves stain and paint. High pressure splinters fibers and forces water into the substrate.
Stone veneer
We adjust solution strength and rinse pressure to avoid loosening grout or driving water behind the veneer.
What we see go wrong
Common mistakes (and how we avoid them).
Renting a pressure washer for the whole house
Rental units come with aggressive tips and no training. The most common result is striped, etched, or water-intruded siding.
Spraying upward into siding seams
Water forced upward gets behind every J-channel and lap joint. It can take weeks for trapped moisture to dry — by then mold has started.
Skipping landscape protection
Strong cleaning solutions burn shrubs and grass if they aren't pre-wet and rinsed.
Cleaning in direct, hot sun
Solutions dry on the wall and leave streaks. We schedule and shade-manage to avoid this.
What affects price
Honest pricing factors.
- Square footage and number of stories
- Siding material (vinyl, brick, stucco, Hardie, cedar)
- Condition — heavy algae or mildew takes more solution and dwell time
- Access — fenced yards, steep grades, and tight side yards add time
- Add-ons such as window washing, gutter brightening, or concrete bundling (usually a discount)
When to book
Seasonality in East TN.
House washing is a year-round service in East Tennessee, but spring and early summer are peak season — pollen + warm humidity push algae growth into overdrive. Booking in late winter or early spring beats the seasonal rush and gets your home ready before the first cookout.
Before we arrive
How to prepare.
- Close all windows and exterior doors the morning of service.
- Move patio cushions, grill covers, and breakable décor away from walls.
- Unlock the side gate and confirm spigot access.
- Let us know about any open electrical, damaged siding, or known leaks.
After we leave
What to expect.
- Expect a clean look immediately — algae spots may continue to lighten over the next few rains.
- Wait 24 hours before painting, staining, or caulking near washed areas.
- Annual or bi-annual washing is the cheapest way to protect siding long-term.

Frequently Asked Questions
A full exterior soft wash of your siding, eaves, soffits, gutters' exterior face, and accessible trim — plus pre-rinse of landscaping, removal of cobwebs and wasp nests, and a final rinse from top to bottom.
Yes. We use a low-pressure soft wash with manufacturer-approved cleaning solutions, which is the method recommended for vinyl, Hardie board, stucco, brick, and painted siding.
No. High pressure can force water behind siding and crack seals. We rely on cleaning solutions plus a gentle rinse — the pressure stays low.
Most East Tennessee homes do best on a 12–18 month cycle. Shaded, wooded, or lakeside homes often need a wash every 9–12 months.
Yes. Our cleaners kill algae, mildew, and mold at the root rather than just rinsing them off, so the clean lasts months longer.
Not when done correctly. Our soft wash process is specifically designed to protect paint, mortar, sealants, and trim while still removing organic growth.
No. As long as we can reach an outdoor water spigot and your exterior, we can complete the work while you're at work or away.
