About granite restoration

Granite is far harder than marble, which is why it is chosen for kitchens, commercial lobbies and stair treads. That hardness also means it needs specialist diamond tooling when it does lose its finish. We restore granite floors and worktops that have become hazy, patchy or chipped.

Many granite worktops that look ‘worn’ are actually coated with residue from multi-surface sprays. A professional strip and re-polish often transforms them in a few hours, without removing them from the kitchen.

For commercial granite — reception floors, shopfront thresholds and stairs — we can work in phases or out of hours to keep areas open.

Every job is quoted at a fixed price after a free assessment. Projects under 100 m² are priced per project; projects over 100 m² are priced per m². Send photos for a fast indicative price.

FAQ

Granite restoration: questions

Why has my granite gone hazy or patchy?

Granite itself is very hard, so dullness is usually caused by residue from multi-surface sprays, failed sealers or resin fillers wearing unevenly. In busy lobbies, fine grit and heavy traffic also dull softer minerals within the stone. Identifying the cause decides whether it needs stripping, re-polishing or both.

What does granite restoration involve?

We strip residues and old sealers, then re-polish the surface with diamond abrasives designed for hard stone. Chips and cracks are filled with colour-matched resin and polished flush. Porous granites are tested and sealed at the end.

How long does granite restoration take?

A kitchen worktop is often done in a few hours to a day, while a granite floor usually takes one to three days depending on size and condition. Commercial lobbies can be phased over several nights to keep them open.

Does granite need sealing?

Some granites are dense and barely absorb anything; others, especially lighter colours, are porous and stain from oil. We test absorbency with water and oil before recommending a sealer, so you do not pay for one you do not need.

Can a chipped granite worktop edge be repaired, and is it messy?

Yes. We fill chips with a colour-matched resin, shape it to the original profile and polish it back so the repair is very hard to spot. Worktop repairs stay in the kitchen, with appliances and nearby surfaces protected and dust kept to a minimum.

How is granite restoration priced?

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. Worktop and small repair jobs are quoted as a single fixed price.
