Houston House & Siding Pressure Washing
House exterior washing is one of the highest-impact curb appeal improvements available to Houston homeowners — and one of the most frequently deferred. Mold, mildew, algae, pollen, and oxidation accumulate on siding faster in humid or shaded environments. A properly executed exterior wash can make a 15-year-old home look freshly painted. The key word is properly: most Houston home siding requires soft washing, not high-pressure blasting.
House pressure washing (technically soft washing for most siding types) in Houston costs $200–$400 for a 1,500 sq ft home and $300–$600 for a 2,500 sq ft home. 20 of 20 verified providers in Houston specialize in exterior house cleaning using low-pressure soft wash techniques appropriate for vinyl, composite, stucco, and wood siding. Service covers the Houston metro including Spring, Katy, Conroe.
Soft washing uses cleaning solutions (typically sodium hypochlorite-based) at low pressure (under 1,000 PSI) to kill mold, algae, and mildew at the root rather than just blasting the surface. This is safer than high-pressure washing for most siding materials and produces longer-lasting results — the biological growth is killed, not just rinsed away. Always ask your Houston provider: "What PSI do you use on siding?" Any answer over 1,500 PSI for vinyl or composite siding is a red flag.

Should I soft wash or pressure wash my house in Houston?
For virtually all residential siding in Houston — vinyl, composite, stucco, cedar, or painted wood — soft washing is the correct method. High-pressure washing can force water under siding panels, strip paint, and damage wood fibers. Soft washing uses low pressure plus biodegradable cleaning solutions that kill mold and algae at the root. Only brick and concrete block can safely handle higher pressure (2,000+ PSI).
How often should I wash the exterior of my house in Houston?
Most Houston homes benefit from exterior washing every 1–2 years. Homes in shaded areas, near trees, or in high-humidity microclimates may need annual washing to prevent significant mold and algae buildup. The best time to wash is early spring (removes winter grime before pollen season) or fall (cleans summer algae before winter). Many Houston homeowners schedule exterior washing alongside window cleaning or landscaping for efficiency.
