Marble · Grout Restoration
Marble showers fail at the grout lines first: dark joints, mould in the corners, cracked caulk at the bench. Vinegar and harsh chemicals etch marble while trying to whiten grout. We deep clean with products that are safe on marble, then regrout, recaulk, and seal.
Quick diagnosis
A pH-neutral scrub may help grout that is intact but dark. If the joints darken again within days, the caulk is peeling, or the grout crumbles when you poke it, more scrubbing won't fix it.

Restore vs replace
Restoring a marble shower (grout, caulk, and stone) usually takes one or two visits. Tearing out the tile and redoing the waterproofing is rarely needed.
Repair path
We decide whether it needs a deep clean, some regrouting, or all new grout.
Alkaline or specialist cleaners pull soap film and dirt out of the joints.
We cut out crumbling grout and old silicone.
Colour-matched grout in the joints, and mould-resistant silicone at corners, benches, and drains.
A grout sealer slows staining. A squeegee and a pH-neutral cleaner make the work last.
