Cornerstone Dublin Epoxy Flooring puts epoxy floor coatings on garage, basement and other concrete floors in Dublin, CA. We grind the slab first, then apply a coating that gives the floor its best resistance to wear and chemicals once it fully cures.
Most people call me because a garage floor is stained, dusty or peeling, or because they just poured a slab and want it finished. The price comes down to how much prep your floor needs, which depends on its size, how many cracks and joints need treating and whether old paint has to come off. If a failed coating is the real problem, stripping it off may come first. The schedule turns on the concrete itself, since a slab that's too new or still damp has to wait, and on the weather while the coating cures. I look at the floor in person and you get the estimate in writing, so the number fits your slab.
How we put down an epoxy floor coating
Before I quote an epoxy floor, I look at the cracks, the joints and any old paint, because each one changes how much prep the job needs. If the slab is too new or too damp to coat yet, I'll tell you plainly and we'll pick a date that suits the concrete. On the day, our crew grinds the concrete so the coating has something to grip, treats the cracks and joints, and vacuums up the dust before any coating goes down. Then we apply the coating and leave the space closed off so it can cure without getting scuffed or driven on.
Most of the epoxy we do at houses ends up in garages, and our garage floor coatings page covers that job in more detail. If you've got a shop or warehouse floor, look at commercial and industrial epoxy floor coatings, where we plan the work around your hours.
Epoxy floor coatings in Dublin, CA, and the permit question
The City of Dublin requires a permit for most construction and repair projects. Its short list of work that doesn't need one names painting, carpeting and similar finish work, but it doesn't name floor coating, so that list doesn't settle your job. The city's Building & Safety Division answers that question, and you can call it at 925-833-6620. When a permit is needed, we take care of the paperwork as part of the job.
We're based in Dublin and work in cities across the Tri-Valley, the East Bay and nearby, so if your city isn't listed, call and ask. A lot of the garage slabs we see here have hairline cracks, saw-cut joints and a coat or two of old paint, and we see the same thing on jobs in Pleasanton and San Ramon, which is why the walk-through before the quote matters so much.
Why call us for epoxy floors
I look at every floor myself
I come out to look at every job myself, and our crew does the prep and the install. The person who sized up your cracks and old paint is the one who decides how the work gets done.
In business since 2017
I learned concrete on my dad's jobs before I was old enough to drive, and I opened this business in 2017. Nine years in, I'd still rather spend the time grinding and checking than rush to the coating.
Licensed and insured on your job
We're licensed and insured. Ask about it when I'm out for the estimate, before anyone sets up a grinder in your garage.
Permit question settled before we start
We check with the office for your city or county before work starts, and in Dublin that means the city's full list of work exempt from a building permit, which goes beyond the short list on its permit page. That way the permit question is answered before our crew shows up.

Frequently asked questions
What does an epoxy floor cost in the Dublin area?
Epoxy floor coating in the Bay Area usually costs about $7 to $10 a square foot, and that covers materials, floor prep and applying the coating. That's a figure for the whole Bay Area, not our price, and on your floor the cracks, joints and old paint decide how much prep you're paying for. Our work is backed by our satisfaction guarantee.
How soon can new concrete be coated with epoxy?
One maker says new concrete should cure for at least 30 days before any coating, and a floor that stays damp can't be coated at all. Its simple check is a weighted rubber mat or plastic sheet left on the floor for 24 hours, and if the concrete underneath comes up darker, it calls for 10 to 14 more days of drying and another test. If your slab is fresh, plan the coating for after that wait and expect a damp floor to push the date back.
What causes an epoxy floor to peel?
Peeling usually comes from the prep, not the coating. One maker prefers shotblasting or diamond grinding, both of which roughen the concrete, and warns that skipping its guidelines can lead to peeling, blistering or coating failure. On a painted floor, another maker says paint that's breaking down comes off to bare concrete, while sound paint gets cleaned and buffed to an even dull finish, so ask any crew how they'll prepare yours.
What causes cracks in an epoxy floor coating?
A coating usually cracks because the concrete under it moves or separates, and the crack comes right back through. That's why joints and cracks get looked at and treated before coating. If your floor has them, ask whether that repair is part of the quote.
How long does an epoxy floor take to cure before I can use it?
Plan on a longer wait when the weather is damp or cool, because high humidity and low temperatures stretch out drying, recoat and cure times. The coating needs protecting from damage the whole time it cures, so keep cars, carts and furniture off until it's done.
Will an epoxy garage floor be slippery?
It can be, since epoxy coatings can be slick on their own. Granular material can be added to give the surface better grip. If you want surer footing, ask for that added grit when you request your estimate.
