Stone cleaning and sealing

If the stone is dirty, stained or has dark grout but is not scratched or etched, a professional deep clean and sealer is usually enough. If it is dull, scratched or etched, it needs honing or polishing. We tell you which at the assessment.

We use stone-safe alkaline cleaners, rotary scrubbing and wet extraction to lift ingrained dirt from the stone and grout. Once dry, an impregnating sealer is applied to slow staining.

No. Impregnating sealers reduce staining from water and oil, but they do not stop acids from reacting with marble. Etching is removed by honing and polishing; protective films are available for high-risk surfaces such as kitchen worktops.

Most rooms take half a day to a day. The floor can be walked on carefully once dry, and the sealer cures fully within about 24 hours.

Cleaning is wet but contained: solution is extracted as we go and nearby surfaces are protected. Loose furniture needs to be cleared.

Usually every one to four years depending on stone and traffic; a water-drop test shows when it is wearing. Projects under 100 m² are priced per job; projects over 100 m² are priced per m², and you get a fixed written quote after a free assessment.
