Pressure Washing in Round Rock, TX

Central Texas's climate creates ideal conditions for exterior surface contamination. Round Rock's combination of high humidity, warm temperatures, and seasonal pollen creates a persistent cycle of algae, mold, mildew, and organic growth on every exterior surface — siding, roofs, driveways, fences, and decks. Left untreated, these biological contaminants don't just look bad; they actively degrade the surfaces they colonize, shortening the lifespan of paint, roofing materials, wood, and concrete.

We provide professional pressure washing and soft washing services across Round Rock and Williamson County. The distinction matters: pressure washing uses high-pressure water to remove surface contamination from hard surfaces like concrete and pavers. Soft washing uses low pressure with professional-grade cleaning solutions to safely remove biological growth from delicate surfaces like siding, roofing, and painted wood — without the risk of surface damage that high-pressure washing causes on these materials.

Every surface gets the appropriate method. We don't use high pressure on roofs or siding. We don't use soft wash on concrete that needs mechanical cleaning. The right method for the right surface is what produces results that last.

Pressure washing and soft washing are distinct cleaning methods suited to different surfaces. Pressure washing uses high-pressure water (1,500–4,000 PSI) to mechanically remove contamination from hard, durable surfaces — concrete driveways, brick, stone, and pavers. The mechanical force of the water dislodges embedded dirt, oil, algae, and staining.

Soft washing uses low pressure (100–500 PSI) combined with professional-grade cleaning solutions — typically sodium hypochlorite (bleach) at appropriate dilutions, surfactants, and neutralizers. The cleaning solution does the work, not the water pressure. Soft washing is the correct method for house siding, roofing, wood decks, and fences — surfaces where high pressure would cause damage (blown-out siding joints, lifted shingles, raised wood grain, stripped paint).

In Round Rock's climate, the primary biological contaminants are Gloeocapsa magma (the algae that causes black streaks on roofs), Cladosporium and other mold species on siding and wood, and various algae and lichen on concrete and hardscape. Professional cleaning solutions kill these organisms at the root — preventing rapid regrowth that occurs when surfaces are cleaned with water alone.

Round Rock's climate accelerates exterior surface contamination in several specific ways. The region's oak and cedar pollen seasons deposit heavy organic material on every horizontal surface — roofs, decks, and driveways accumulate pollen that feeds algae and mold growth. The high humidity during spring and fall creates extended periods of surface moisture that biological growth requires to establish.

The black streaks on roofs throughout Round Rock are Gloeocapsa magma — a cyanobacteria that feeds on the limestone filler in asphalt shingles. It's airborne and spreads from roof to roof across neighborhoods. It's not cosmetic — it actively degrades shingles by consuming the protective granules. Soft washing with the appropriate bleach solution kills it at the root. Pressure washing a roof does not — it removes the visible growth but leaves the organism in the shingle substrate, where it regrows within 6–12 months.

Driveway algae in Round Rock is particularly stubborn because the region's limestone-based concrete is porous and provides an ideal substrate for biological growth. Surface cleaning without a post-treatment application results in regrowth within 3–6 months. We apply a post-treatment algae inhibitor after driveway cleaning to extend the clean period to 12–18 months.

Every job starts with a surface assessment — we identify the contamination type, surface material, and appropriate cleaning method before starting. For house washing, we pre-treat the siding with a soft wash solution, allow dwell time for the solution to kill biological growth, then rinse at low pressure. For driveways, we pre-treat with degreaser (oil stains), apply cleaning solution, surface clean with a rotary surface cleaner at appropriate pressure, then post-treat with algae inhibitor. For roofs, we apply soft wash solution at low pressure, allow dwell time, and rinse — no high pressure at any point.

We protect landscaping before every job — covering plants near the work area and rinsing vegetation after soft wash applications. We use biodegradable, plant-safe cleaning solutions wherever possible. We don't leave cleaning solution residue on surfaces or in landscaping.

We use the right method for each surface — soft wash on roofs and siding, appropriate pressure on concrete. We apply post-treatment algae inhibitor on driveways and concrete to extend the clean period. We protect landscaping before every job. We're licensed and insured in Texas. We provide written quotes before any work begins. We're a Round Rock-based operation — the same crew that does the work answers the phone.
