If one side of your fence is warm honey-brown and the other is streaked green and gray, you’re seeing Austin’s climate at work — not the end of your fence’s life. The same humidity that makes Central Texas summers sticky feeds algae and mildew on any surface that stays shaded and damp, and a cedar fence or the north wall of your house is the perfect host. The discoloration looks permanent. It almost never is.
We’re a locally-owned exterior cleaning company serving Austin and the surrounding metro — Cedar Park, Round Rock, Pflugerville, Buda, and Kyle. Here’s what fence and siding cleaning costs in Austin in 2026, why one side always greens up first, and how to clean both without forcing water where it shouldn’t go.
Price depends on the material, the square footage, and how much organic growth has built up. A short vinyl fence is quick; a long cedar privacy fence with a heavily shaded, algae-covered run takes more solution and more care. These are honest 2026 starting ranges — your written quote locks in the exact number before we start.
| Service | Starting | Typical range |
|---|---|---|
| Wood / cedar fence | $99 | $99–$249 |
| Vinyl or aluminum fence | $99 | $99–$199 |
| Siding soft wash (vinyl / Hardie) | $149 | $149–$349 |
| Stucco or brick siding | $149 | $149–$349 |
| Fence + house wash combo | $299 | bundle pricing |

Algae, mildew, and mold need three things: moisture, shade, and something to cling to. In Austin, the north and east faces of a fence — and the shaded walls under your live oaks — stay damp far longer after rain and morning dew than the sun-baked sides. That’s why one run of fence can look brand new while the panel ten feet away is coated green. It isn’t dirt you can scrub off; it’s living growth with roots in the surface, which is why a garden hose barely touches it.
Cedar has a second problem: UV. The sunny side bleaches to silver-gray as the surface oxidizes. A proper cleaning lifts both the green growth and the gray oxidized layer, evening the whole fence back out to its natural tone.
Siding is the one place where high pressure does the most hidden damage. A powerful tip can crack vinyl, chip the painted surface of fiber cement, blow chunks out of stucco, and — worst of all — drive water up behind the panels and into the wall cavity, where it leads to mold and rot you won’t see until it’s expensive. Soft washing cleans with solution and low pressure aimed correctly, so the growth comes off and the water stays where it belongs.
It’s optional, but worthwhile. Cleaning removes the gray oxidation and the green growth and gives you bare, even cedar — the ideal surface for a sealer or stain to bond to. If you want to slow down future graying, seal within a week or two once the wood has dried out. If you’d rather let it weather naturally, an annual clean keeps it looking healthy on its own. While we’re out, many homeowners pair the fence with a full house wash or a deck and patio cleaning so the whole exterior matches.
For most Austin homes, once a year keeps both looking sharp — ideally in spring after the oak catkins and pollen finish dropping. Heavily shaded fences and the north walls of homes under a thick live-oak canopy green up faster and sometimes want a second pass. If you’re weighing the whole exterior at once, our 2026 Austin pricing guide lays out how the services fit together.
We serve Austin and the surrounding metro — including Cedar Park, Round Rock, Pflugerville, Leander, Buda, and Kyle — from older neighborhoods with weathered cedar privacy fences to newer subdivisions with vinyl and Hardie. Not sure if you’re in range? Ask when you request your quote and we’ll tell you straight.
Fence cleaning starts at $99. The final price depends on the material, the length and height of the fence, and how much algae or gray staining has built up. Siding soft washing starts at $149. Your written quote gives you the exact number before any work begins.
The green side is the shaded, damp side — usually facing north or east, or sitting under tree canopy. Algae and mildew thrive where moisture lingers, so that face grows a living film while the sun-baked side stays clear. A soft wash clears the growth and evens the whole fence back out.
Yes. That’s the entire point of soft washing. We clean with solution and low pressure at the correct angle, so the algae and mildew lift off without driving water up behind the panels into the wall cavity.
Vinyl, fiber cement (Hardie board), stucco, brick, and wood siding all clean up well with soft washing. We match the solution strength and pressure to the material so each one is cleaned safely.
It’s optional. Cleaning gives you bare, even cedar that’s ideal for a sealer or stain if you want to slow future graying — apply it after the wood has dried for a few dry days. If you prefer a natural weathered look, an annual cleaning keeps it healthy without sealing.
