Onyx is one of the most striking natural stones you can bring into a home, prized for its translucency, dramatic veining and glassy polished finish. It is also one of the softest and most delicate stones, which means chips, cracks, scratches and dull patches are far more common than owners expect. Shazam Repairs provides specialist onyx repair across London, restoring damaged onyx surfaces in place so you keep the stone you fell in love with rather than facing a costly replacement.
Onyx Repair Services We Offer
We repair onyx worktops, vanity tops, feature walls, tabletops, bar tops and backlit onyx panels. Our technicians carry out chip repairs to edges and corners, fill and stabilise cracks, and treat scratches and etch marks that spoil the polished surface. We also re-polish dull or acid-etched areas to bring back the depth and shine that makes onyx so distinctive, and colour-match any filler to the natural veining so the repair disappears into the stone. Because onyx is translucent, blending is a real craft, and it is exactly the kind of work our stone and marble repair team specialises in.
Who We Work With
Onyx tends to appear in high-end settings, so we regularly work with homeowners protecting a luxury bathroom or kitchen, along with interior designers, developers and stone suppliers who need installation or handover damage put right. Hotels, restaurants, bars and members’ clubs across London also call on us to keep statement onyx surfaces looking immaculate, and facilities managers rely on us for fast, discreet repairs that avoid closing an area for a full replacement.
Areas We Cover
Our mobile teams cover all of London, including central, north, south, east and west, from Kensington, Chelsea, Mayfair and Westminster to the City, Canary Wharf and the surrounding boroughs. We also travel out across the Home Counties and into Essex and Surrey for larger commercial and residential projects. If you are just outside London, get in touch and we will let you know if we can reach you.
Why Choose Shazam Repairs for Onyx
Onyx is unforgiving of poor workmanship, so experience matters. Our technicians understand how the stone behaves, how to stabilise a crack without it spreading, and how to match filler to translucent veining so light still passes through the repair. Repairing in place is faster, cleaner and far more sustainable than lifting and replacing a rare slab, and it protects the character of stone that is often impossible to source again. We also carry out scratch repairs and polishing on the same visit where possible, keeping disruption to a minimum.
Onyx Repair FAQs
Can a chip or crack in onyx really be repaired, or does it need replacing?
In the majority of cases onyx can be repaired in place rather than replaced. Chips and cracks are cleaned, stabilised and filled with a resin colour-matched to the stone’s veining, then polished back to a smooth finish. Whether repair is the best route depends on the size and position of the damage, so it is always worth having it assessed before assuming the whole slab needs to come out.
Why is my onyx surface losing its shine and developing dull, cloudy patches?
Onyx is a soft, calcium-based stone that etches easily when it meets anything acidic, such as wine, citrus, coffee or many household cleaners. Those dull marks are microscopic surface damage rather than dirt, which is why they will not wipe away. In most cases we can re-polish the affected areas to restore the depth and clarity, and we will advise on gentle, stone-safe cleaning to keep it that way.
How much does onyx repair cost?
The cost depends on the type and extent of the damage, the size of the surface and the finish involved, so there is no single figure. Repairing in place is almost always more economical and far less disruptive than replacing a rare onyx slab. Send us a few clear photos of the damage and we will come back with a fast, no-obligation quote tailored to your surface.
