We restore marble and natural stone by diamond cutting, honing and polishing. We do this by repeatedly passing varying grades of metal and resin bonded diamond abrasives over the surface of your marble or stone with planetary head rotation machines.
This allows the removal of lippage, scratching, chemical etching and staining; delivering a sealed, anti-slip, surface in the finish of your choice.

Chemical Cleaning
We offer chemical cleaning where sanitation or topical treatment is required and the surface of your floor or top cannot be physically altered by polishing.

Grout Restoration
We can deep clean or entirely router out and replace your grouting.

Our Approach

  • Retained maintenance for never-ending renewal to keep your floors and tops at their best, avoiding future restoration work
  • Rednum’s marble and stone specialists will work closely with and compliment your night cleaning team
  • Our custom programmes offer regular diamond polishing visits to remove the daily build-up of scratches, stains and etching in your premises
  • Diamond Polishing delivers a deep and natural shine without harmful chemicals, leaving a scratch free and sealed floor, in an anti-slip finish


  • Full public liability insurance of £10,000,000
  • Full COSHH and RAMS compliance
  • We invest in rigorous employee selection, training and development to ensure a highly skilled and professional workforce
  • We are an equal opportunities employer
  • Our environmental footprint is light because diamond polishing is a natural process relying on the minimum of chemical products
