How the work is assessed and completed
Careful Assessment
We evaluate your onyx with extra care—checking for fragile areas, existing repairs, and hidden damage before creating a restoration plan.
Gentle Cleaning
We use pH-neutral solutions specifically suited for onyx's sensitivity. No harsh chemicals that could damage the stone.
Precision Honing
Using fine diamond abrasives, we carefully remove etch marks and scratches without over-grinding this delicate stone.
Expert Polishing
We polish to restore onyx's signature translucent glow—the quality that makes it unlike any other stone.
Premium Sealing
We apply multiple coats of penetrating sealer to protect against staining while preserving the stone's natural beauty.
Onyx Restoration questions
Do you offer onyx cleaning and sealing?
Yes. Our onyx cleaning and sealing service starts with a pH-neutral deep clean of the stone and grout to lift embedded soil, residue and old sealer. Once the onyx is clean and dry, we apply a penetrating sealer to help slow down staining. Floors, showers, vanities and countertops can be done. Text photos for a quote.
Is onyx harder to restore than marble?
Yes—onyx is softer and more fragile than marble. It requires more careful handling, gentler techniques, and greater expertise. Not all stone restoration companies work with onyx.
Can you fix chips in onyx?
Yes. We use color-matched fillers and careful polishing to repair chips. Due to onyx's translucent nature, repairs require extra skill to blend invisibly.
How do I protect onyx surfaces?
Always use coasters, avoid acidic substances, clean with pH-neutral products only, and have it professionally sealed annually. We provide detailed care instructions.
Can backlit onyx be restored?
Yes. We restore the surface without affecting the backlighting. In fact, polishing often improves the translucent effect that makes backlit onyx so dramatic.
