Tile Regrouting & Grout Repair Services in Oxford, MS

Regrouting in the Oxford, MS area is typically priced by the square foot — expect $3–$8 per sq ft for labor depending on tile size, grout joint width, and accessibility. Small bathrooms under 50 sq ft often fall under a flat-rate minimum of $250–$400. Shower stalls with intricate mosaic floors cost more due to the density of joints. We provide a detailed estimate before any work begins so there are no surprises.

No. Applying new grout directly over old grout is a shortcut that fails quickly. New grout won't chemically bond to cured old grout — it sits on top and cracks within months. Our process is always removal first: we use oscillating multi-tools and precision grout saws to excavate the old material to a depth that allows a solid new grout joint, without chipping your tile edges. The result is a bond that lasts.

Standard sanded and unsanded grouts require 24 to 48 hours of cure time before the surface is exposed to water. Epoxy grout sets faster — often 24 hours — but requires more exacting application. If we apply a penetrating sealer after grouting (which we recommend for non-epoxy grout in wet areas), allow an additional 24 hours before use. We'll walk you through the timeline on the day of the job.

Cracking grout has several common causes. House settling and substrate flex are the most frequent — when the floor or wall moves slightly, rigid grout joints fracture. Improper grout mixing (too much water) weakens the cured product. Missing expansion joints at wall corners allow thermal movement to shear the grout lines. And in some cases, grout that was applied too thin or over a contaminated surface simply never bonded correctly. We diagnose the root cause so the repair doesn't repeat.

Yes — provided you have a matching tile on hand. Single-tile replacement is a precision job: we score and remove the damaged unit without disturbing adjacent tiles, re-bond with fresh thin-set, re-grout the surrounding joints, and seal. If you don't have a spare, we can sometimes source a close match or recommend pulling a tile from a hidden area (like inside a cabinet) to use as the patch.

Yes. Mold embedded in porous grout cannot be fully eliminated with surface cleaners — the hyphae penetrate the grout body. Physical removal of the old grout takes the mold with it. We clean and treat the tile edges and substrate before installing fresh grout, then seal the new joints to prevent moisture absorption that feeds future growth. If mold has migrated behind the tile into drywall, we'll flag that and coordinate with our drywall repair team.

For cement-based grouts — which includes most sanded and unsanded products — yes, sealing is essential. Unglazed grout is porous and will absorb water, oils, and pigments from everyday use, leading to staining and accelerated mold growth. A quality penetrating sealer fills the micro-pores without altering the appearance and typically lasts 1–3 years in a shower, longer in lower-traffic areas like backsplashes. Epoxy grout is non-porous and does not require sealing.
