Pressure Washing & Soft Washing in Houston, TX
Houston's humid subtropical climate keeps surfaces damp almost year-round, and that is exactly what algae, mildew and lichen need. With very high humidity, long summers regularly above 95°F and mild but damp winters, driveways, patios, fences and north-facing siding can go green and slick between cleanings. Closer to the Ship Channel and Galveston Bay, salt-laden air and industrial humidity add a gritty film that dulls brick veneer, painted trim and aluminum.

Why pressure washing is different in Houston
Most Houston homes date from around 1980, according to U.S. Census Bureau ACS 5-year (2022) data, which means a lot of brick-veneer suburban houses with composition shingle roofs and wood fences that are now decades into Gulf Coast weather. Those roofs are the reason we soft wash instead of blasting: high pressure strips granules off asphalt shingles and can void shingle warranties, while algae and lichen left in place hold moisture against roofing and siding. On slab-on-grade homes over expansive clay, driveway aprons and walkways shift and crack with wet and dry spells, so we adjust technique around lifted joints, soft mortar and older wood rather than forcing pressure where it does damage.
Problems we fix in Houston
- Slippery algae on walkways and pool decks
Constant Houston humidity keeps concrete damp long enough for algae to take hold, and a green film on a walkway or pool deck gets dangerously slick when wet. A surface cleaner removes it evenly without the zebra striping a wand leaves behind.
- Roof streaking on 1980s-era shingles
Dark streaks on composition shingle roofs are typically algae feeding on moisture that never fully dries in this climate. Low-pressure soft washing treats it without knocking granules loose the way high pressure does.
- Oxidized vinyl and aluminum siding
Long, hot Houston summers plus salt-laden air on the east and southeast sides leave a chalky oxidized layer on vinyl and aluminum. Aggressive pressure can streak or gouge that surface, so it needs a soft wash approach and careful rinsing.
- Water forced behind siding and window frames
Wind-driven rain during hurricane and tropical-storm season already tests siding laps and window seals. Pressure aimed upward or into a seam can push water into the same gaps, which is why direction and distance matter more than raw power.
- Storm grime and debris film after tropical weather
June through November storms and spring thunderstorms leave mud splatter, leaf stain and organic film on patios, screen enclosures and fences across the metro. Cleaning it off before it sets keeps stains from bonding into concrete pores.
- Rust and oil stains on driveways
Detached homes with attached one- and two-car garages dominate Houston, so driveway oil drips and fertilizer rust marks are a regular sight. These need targeted stain treatment rather than more pressure, which usually just etches the concrete.
- Damage to soft wood, mortar and landscaping
Inner-loop early-1900s wood-frame bungalows and older mortar joints can be chewed up by too much pressure, and runoff can burn plantings. We control pressure, pre-wet and rinse landscaping, and work around beds and turf.
What we do
Flat concrete is cleaned with a surface cleaner for an even finish, including aprons and joints that have shifted with Houston's expansive clay soils. Rust and oil stains get treated separately.
Low-pressure soft washing handles brick veneer, vinyl, aluminum and composition shingle roofs common on 1970s–2000s Houston subdivisions. The goal is removing algae and lichen without stripping granules or driving water behind siding.
Wood fences and decks in this humidity gray out and grow mildew quickly, and screen enclosures collect film and pollen. Pressure is dialed down for soft wood and screen mesh.
Gulf Coast rain leaves tiger-striping on gutter faces that a normal house wash will not remove. Brightening treats that oxidized streak so the trim line matches the cleaned siding.
After cleaning, concrete can be sealed to slow re-staining and make algae easier to rinse off in Houston's damp months. We explain the tradeoffs before you decide, and the estimate is free either way.
Licensing, permits and codes in Texas
Texas has no statewide general contractor or home improvement contractor license, and exterior cleaning is generally not a licensed trade on its own; the Texas Department of Licensing and Regulation (TDLR) is the primary state agency for most licensed construction trades, including electricians and air conditioning/refrigeration contractors. If your project touches work that is separately regulated — plumbing and gas piping fall under the Texas State Board of Plumbing Examiners — that portion should be handled by the appropriate licensed trade. Wash-water runoff and any local requirements can vary, so verify with TDLR and your local authority, and if you live in one of Houston's widespread master-planned HOA or gated communities, check your association's rules before scheduling.
Timing and availability
Work tends to cluster around spring hail and thunderstorm season, again through the June–November hurricane season and the cleanup that follows, and briefly during January–February cold snaps. Late winter and early spring are good windows for a full house wash before the heat and humidity climb, while post-storm cleaning is often about removing debris film before it sets. Our phones are answered 24/7 at (888) 996-7488, and technicians in the Houston area can usually be scheduled same-day or next-day, with a free estimate before any work begins.

Pressure Washing questions in Houston
Will pressure washing damage my roof?
High pressure strips granules off asphalt shingles and can void shingle warranties, so we do not use it on roofing. Composition shingle roofs on Houston's 1980s-era subdivisions get low-pressure soft washing instead, which lifts algae and lichen without abrading the surface.
Why does mildew come back so fast in Houston?
Houston's humid subtropical climate keeps very high humidity year-round, and mild, damp winters never really dry surfaces out. That is why shaded siding, fences and north-facing concrete regreen faster here than in drier climates, and why sealing concrete is worth discussing.
Do you clean homes near the Ship Channel and Galveston Bay?
Yes. Houston sits on the Gulf Coast plain roughly 50 miles from the open Gulf, and salt-laden air plus industrial humidity on the east and southeast sides leave film on siding and hardware. Those surfaces usually benefit from a soft wash on a shorter cycle.
What about my landscaping and my neighbors' property?
Runoff onto landscaping is a real hazard, so beds and turf are pre-wet and rinsed, and we plan where water goes before starting. In dense inner-loop and townhome redevelopment areas where houses sit close together, we also plan around shared walls and driveways.
I rent — can I schedule this myself?
Census data shows about 42% of Houston homes are owner-occupied, so many callers are renters or property managers. Renters should get the owner's approval first, since exterior cleaning affects the building; we're happy to give the owner a free estimate.
