Does my old floor coating need to be stripped or just patched?
Concrete floor stripping and removal in Antioch, CA takes an old coating, floor leveler or glue residue off your slab and leaves bare concrete that's been checked before anything new goes on.
Most calls start with a garage or shop floor that's peeling where the tires sit, bubbling in patches or lifting at the edges, and the first thing you want to know is how much has to come off. The price moves with the size of the floor, what's on it and how many layers there are, and whether it's a patch or the whole slab. The schedule turns mostly on the moisture test, because nothing new goes down until the bare concrete passes it. I come out, look at the slab and give you a written estimate with your own number on it.
How we handle concrete floor stripping and removal
I start by reading the damage, because it tells us whether you need a patch or a full removal, and I'll tell you which before you pay for more than you need. Then we pick the removal method that fits what's on the floor and take it down to bare concrete, which also opens up the surface so the next coating has something to grip. We clean the slab off, and once it's bare we test it for moisture before anything new goes on, because a coating laid over a slab that's pushing water up won't stay put.
Once the slab is bare and dry, most homeowners want a new finish, and our epoxy floor coatings go right onto the surface the removal leaves. For shops, warehouses and other working floors, the same removal comes before commercial and industrial epoxy floor coatings, so the heavier system starts on clean concrete.
Why Antioch homeowners call Sterling Antioch Concrete Coatings for floor removal
I write the estimate myself
I come out to look at your floor and write the estimate, and then I run the job with our crew. The person who told you patch or full removal is the one making that call on the day we grind.
Grinding dust kept out of the air
Grinding concrete throws off a lot of silica dust, which is a real danger to your lungs, and California requires a dust reduction system on powered tools that grind concrete. Our grinders run with one, and you're right to ask any crew how they'll keep the dust down before they start.
Licensed and insured for floor prep
We're licensed and insured. California's contractor licensing board counts preparing a surface for flooring and floor coverings as flooring contractor work, and taking an old coating off is exactly that prep.
Since 2013, judged by the prep
We've been doing this since 2013, and I judge our floors by how they hold up, not how they look the day we finish. Removal is where that starts, because a new coating is only as good as the bare concrete under it.
What matters most here is knowing what's under the old coating before you choose the next one. Call (925) 503-1069 or send us a message with the floor's size in square feet, the kind of coating on it and a few photos of where it's failing.
Get a written estimate for your coating removal
We reply to every call and message within one business day, and the on-site estimate is free with no obligation. After you send this, I'll set a time to come look at the slab, ask how you use the space and give you a written estimate that says whether it's a patch or a full removal.

Questions before you book floor stripping
Should I repair my epoxy garage floor or have it all removed?
If the coating is still bonded and sound across most of the floor with one bad area, it's usually a repair, and if it's letting go everywhere, bubbling across big sections or has moisture pushing up through the slab, it needs to come off. That's how one supplier's guide sorts it, and the damage is what I look at first at the estimate.
How much does concrete floor coating removal cost per square foot?
Medium concrete grinding to remove glue or mastic in California usually costs about $3.25 to $4.50 per square foot. That's a statewide market figure, not our price. Your number comes in a written estimate after I've seen the floor.
What is the best way to remove epoxy from a concrete floor?
For most home floors, diamond grinding is the best way, because it takes the old coating off and preps the slab at the same time. A chemical stripper works best on a thin, single-coat floor or a small spot, and on thick multi-coat systems it mostly softens the top layers so grinding goes faster, with the slab still needing cleaning and prep afterward. Shot blasting, which fires small steel balls at the slab, is faster on big industrial floors, but its setup rarely makes sense for one garage.
Could my old flooring in Antioch contain asbestos?
It could, since the Bay Area Air District lists vinyl floor tiles and mastics among materials that might contain asbestos. Where its rules apply, the Air District must be notified at least 10 business days before a renovation that removes 100 square feet or more of asbestos. If I see old tile or black glue at the estimate, I'd want it tested before anyone grinds it.
How do I apply for a building permit in Antioch?
You apply online through the city's permit portal, and the City of Antioch Building Division handles building permit applications in the city. If your job calls for one, we'll tell you at the estimate and settle who gets it before work starts, and if I'm not sure, I check with the building office first.
How long does a moisture test take after coating removal?
The standard test takes 24 hours, with a sealed plastic sheet on the bare concrete that's checked the next day. Condensation under the sheet means water is moving up through the slab, and a new coating will only hold once a moisture barrier goes on the bare concrete first.
Work that often follows removal
- Epoxy Floor Coatings
If you want a fresh, hard-wearing finish once the old one is gone, a new epoxy coat bonds to the open, bare concrete that grinding leaves behind.
- Commercial & Industrial Epoxy Floor Coatings
Shops, warehouses and other working floors that take forklifts, carts and spills need a heavier coating system, and stripping the old one is usually the first step.
