Grout Cleaning & Sealing in Texas
Texas Stone Sealers cleans and seals grout — the cement-based filler between tile surfaces — across Texas. Tile grout is the dirtiest part of any tile installation: porous, cement-based, and recessed below the tile surface, grout collects dirt, soap scum, mold, mildew, and food residue that no amount of household cleaning fully removes. Texas Stone Sealers restores grout to near-new appearance and seals it against recurrence.
Grout is porous concrete
Grout — whether sanded grout, unsanded grout, or epoxy grout — is fundamentally a cement-based filler. (Even epoxy grout includes filler particles that hold dirt.) The recessed channels between tiles collect everything that lands on the tile surface, plus moisture that wicks down from cleaning. The result is uniformly darkened, stained, or mildewed grout — even when the tiles themselves still look clean.
Grout cleaning & sealing applications
- Tile floors — kitchens, baths, entries, hallways
- Shower stalls & tub surrounds — heaviest mold and mildew exposure
- Backsplashes — kitchen food and grease, bath cosmetics
- Countertops with tile inserts
- Outdoor tile patios
The Texas Stone Sealers grout process
Texas Stone Sealers uses hot-water extraction with specialized grout-cleaning chemistry — drawing soil out of the grout matrix rather than just scrubbing the surface. Mold and mildew are killed with biocide treatment. After full drying, a penetrating TSSPRO CLT grout sealant is applied — the sealant cross-links inside the grout matrix and dramatically resists future staining and biological growth.
Color-sealing transforms tired grout
Severely discolored grout that won't clean to a uniform appearance can be color-sealed — a tinted TSSPRO CLT formulation that recolors every grout joint to a consistent color while sealing it permanently. About CLT →
Frequently asked questions
Can old, discolored grout be cleaned, or does it need replacement?
Almost always cleaned, not replaced. Texas Stone Sealers' hot-water extraction process removes embedded soil that surface cleaning cannot reach. Color-sealing is the backup option for permanently discolored grout.
How long does grout sealing last?
Floor grout typically benefits from resealing every 1–3 years; shower grout 1–2 years given moisture exposure.
