Cleaning fixes dirt. It doesn't fix etches, scratches, or worn traffic lanes.
Limestone is soft, porous, and calcite-based. What looks like dirt is usually damage.
Restore. Don't replace.
Commercial limestone restoration is a fraction of tear-out and reinstall. Restoration costs a fraction of what tear-out and reinstall costs. Replacement of commercial limestone often runs multiple times that once demolition, tile, install, and downtime are included.
Etches from wine, coffee, cleaning acids, and mineral water
Cloudy patches where the finish is worn down
Worn traffic lanes at doorways, elevators, and entry mats
Scratches under furniture, planters, and cart wheels
Sealer failure that stopped protecting the stone
Seam and edge damage where surfaces meet
The Pure Light Standard™
The standard you hire is the standard that shows up.
The craft, step by step.
Stone ID and diagnostic.
Free on-site estimate. If you don't know what stone you have, we identify it with professional Stone ID kits before we scope a project.
Deep clean.
A neutral-pH clean pass lifts embedded soil and opens the surface for craft work.
Grind, hone, polish.
A multi-grit progression that levels wear, closes cloudy patches, and rebuilds the finish the surface actually deserves.
Etch and scratch repair.
Targeted work on the damage you can point to, from wine rings to cart-wheel scratches.
Color match where needed.
When a fill or repair is involved, we match the color so the repair reads as part of the floor.
Penetrating sealer or coating.
We finish with a penetrating sealer to lock in the result, matched to the stone and to the traffic the floor actually takes.
Marble, Travertine, Limestone. One family, one specialty.
Restored. Surpassed. Or refinished the way the space actually wants it.
We restore the original factory finish, and can surpass or change it depending on what the space needs. Honed, polished, matte, the choice is yours.
Restore.
Bring the surface back to factory finish.
Surpass.
Take the finish higher than the day it was installed.
Change.
Move from polished to honed or matte, on your call.
Restoration is step one. Coating is step two.
Every Pure Light™ commercial limestone project finishes with a penetrating sealer or a coating (sometimes called a topical sealer). RexPro is our default commercial coating. For high-etch-risk surfaces like bar tops and restroom counters, MORE™ AntiEtch™ is available. Pure Light™ is a MORE™ AntiEtch™ Certified Applicator, one of only two in San Diego County, with a lifetime warranty on jobs completed October 2025 and later.
Buildings we take care of.

Commercial buyer questions we hear on every project.
Will a restored limestone look as good as replacement?
In most commercial spaces, yes. We restore the original factory finish and can surpass or change it depending on what the space needs. If our first method doesn't solve it, we adjust methods until the expected result is achieved, within the realistic boundaries of the surface.
How long is the space out of service?
Every project is scoped to your operations. Most commercial limestone restorations run one to three days per zone, and large lobbies or multi-zone projects are staged so the whole space is never down at once. Your operations lead sees the schedule before we start.
Do you work off-hours?
We coordinate low-disruption windows with your team, and can work off-peak or overnight when a space requires it. Off-hours work is real, but it isn't our default cadence, we recommend it only when a space truly requires it.
What's the warranty?
On the restoration itself, our promise is straightforward. If our first method doesn't solve it, we adjust methods until the expected result is achieved, within the realistic boundaries of the surface. On MORE™ AntiEtch™ jobs completed October 2025 and later, MORE™ AntiEtch™ carries a lifetime warranty on stains and etches.
How do you coordinate a multi-site rollout?
One point of contact, one schedule, one standard on every site. Approximately 70% of our monthly jobs are repeat customers, and multi-site portfolios like Cajon Valley Union School District run on that same standard.
