Mold & Mildew Removal in Texas
Texas Stone Sealers removes mold, mildew, algae, and lichen from outdoor stone, brick, concrete, and paver surfaces across Texas. Texas humidity, irrigation overspray, shade from mature trees, and tight-fit construction all foster biological growth that's nearly impossible to remove with household cleaning — but is straightforward for Texas Stone Sealers' biocide and surface-prep system.
Why biological growth thrives on Texas surfaces
Mold, mildew, algae, and lichen need three things: moisture, organic nutrition (atmospheric grime suffices), and weak biocidal protection. Texas summers provide humidity above 80% for months at a time, daily afternoon shade plus irrigation overspray keeps surfaces wet, and porous stone surfaces lock in moisture for hours after rain. The result: dark biological staining that masks the original stone color and accelerates substrate deterioration.
How Texas Stone Sealers removes biological growth
- Identification. Mold, mildew, algae, and lichen each respond to different treatment chemistry. Texas Stone Sealers identifies which is present.
- Biocide pre-treatment. Biodegradable, substrate-safe biocides kill at the spore level — not just visible growth.
- Removal. Soft-stone cleaning, pressure washing, or soda blasting depending on substrate and severity.
- Sealing. A TSSPRO CLT sealant locks out moisture and dramatically slows recurrence — surfaces stay clean for years instead of months.
Common biological-growth surfaces Texas Stone Sealers treats
- Shaded flagstone patios
- North-facing limestone facades
- Pool deck zones near landscaping
- Stone retaining walls and steps
- Brick walls in shaded yards
- Roof shingles and slate (soft-wash methodology)
Cleaning without sealing is a treadmill
Pressure washing without sealing produces a clean surface that recontaminates within months. Texas Stone Sealers pairs biocide treatment with TSSPRO CLT sealing — the surface stays clean, year after year. About CLT →
Frequently asked questions
Is the biocide safe for plants and pets?
Texas Stone Sealers uses biodegradable biocides and protects landscaping with pre-rinse coverage and thorough post-treatment rinsing. Plants and pets are safe.
Can sealed surfaces still develop mold?
Far less. Sealing dramatically slows but does not eliminate biological growth in extremely shaded, wet conditions. Sealed surfaces are also much easier to clean when growth does occur.
