Why Houston Homes Need Professional Soft Washing
Houston’s subtropical climate creates the perfect environment for mold, mildew, algae, and other organic growth to colonize your home’s exterior surfaces. With average humidity levels above 75% and over 50 inches of annual rainfall, virtually every home in the Greater Houston area will develop unsightly dark streaks, green patches, and dingy discoloration over time.
These aren’t just cosmetic issues. Left untreated, biological growth can deteriorate your siding, compromise your paint, and reduce your property value. The National Association of Realtors estimates that professional exterior cleaning can increase a home’s value by 5-10%, making house washing one of the highest-ROI home maintenance investments you can make.

Soft Washing vs. Pressure Washing: What’s the Difference?
Many homeowners assume that blasting their home with high-pressure water is the best way to clean it. In reality, high-pressure washing can cause serious damage to residential exteriors, including cracked siding, stripped paint, water intrusion behind walls, and voided manufacturer warranties.
Soft washing uses low-pressure water (about 60 PSI — similar to a garden hose) combined with specialized, biodegradable cleaning solutions that kill mold, mildew, algae, and bacteria at the root. This approach is endorsed by major siding manufacturers including James Hardie, LP SmartSide, and CertainTeed.
The key advantages of soft washing over high-pressure methods include:
- Safer for surfaces: No risk of cracking, chipping, or forcing water behind siding
- Longer-lasting results: Kills organisms at the root rather than just blasting away surface growth
- Manufacturer approved: Follows guidelines from ARMA, James Hardie, and other major brands
- Protects your investment: No risk of voiding your siding or paint warranty

Our House Washing Process
At Houston Texas Power Washing, we follow a meticulous six-step process designed to deliver the best possible results while protecting your property.
Step 1: Pre-Wash Inspection
We walk the entire exterior of your home, noting surface types, stain sources, and areas that need special attention. We also identify and protect delicate items like outdoor speakers, security cameras, and decorative fixtures.
Step 2: Landscape Protection
Before any cleaning begins, we wet down surrounding landscaping and cover sensitive plants. Our solutions are biodegradable and plant-safe, but we take every precaution to protect your garden.
Step 3: Solution Application
We apply our proprietary soft wash blend using calibrated, low-pressure equipment. The solution contains surfactants that help it cling to vertical surfaces, ensuring maximum contact time with biological growth.
Step 4: Dwell Time
The cleaning solution needs time to work. During this phase, it penetrates deep into porous surfaces, killing mold, mildew, and algae colonies at the root — not just on the surface.
Step 5: Thorough Rinse
We rinse every treated surface using low-pressure water, working from top to bottom. This removes the cleaning solution along with all the dead organic material, leaving your home looking like new.
Step 6: Final Inspection
We walk the property with you to ensure every area meets your expectations. If anything isn’t perfect, we address it on the spot.
Houston’s Climate: Why Regular House Washing Matters
Houston sits in USDA Hardiness Zone 9a, with hot, humid summers and mild, wet winters. This climate is ideal for biological growth, and your home’s exterior is constantly under attack from:
- Gloeocapsa magma — The black algae responsible for dark streaks on roofs and siding
- Green algae — Thrives on shaded, north-facing walls and under eaves
- Mold and mildew — Flourishes in Houston’s persistent humidity
- Pollen accumulation — Heavy spring pollen seasons leave a yellow-green film on surfaces
Regular soft washing every 12-24 months keeps these organisms in check, protects your home’s finish, and maintains your property’s curb appeal and value.
