Epoxy Floor Coatings
A solid epoxy coat over a properly ground slab suits Dublin garages and utility rooms where you want a floor that wipes clean and stands up to oil and tracked-in dirt.

The Dublin floors we're called about most
Many Dublin garages do more than hold cars. They hold a home gym, a workbench, a second freezer and years of storage. By the time we're called, the floor usually shows oil stains, dusty concrete or store-bought paint peeling where the tires sit. That peeling nearly always comes from paint rolled onto a slab that was never ground, so it had nothing to grip.
Some homes here sit on sloped lots up toward the hills, and their garage slabs are pitched toward the door so water runs out. We grind and coat to keep that pitch, and we look closely at cracks where the slab meets a step or the driveway. We do the same work just north in San Ramon and south in Pleasanton.

Floor and concrete work we do in Dublin
Commercial & Industrial Epoxy Floor Coatings
For Dublin shops, warehouses and back rooms that take carts, pallet jacks and spills, we install thicker epoxy systems built for steady traffic and regular cleaning.
Garage Floor Coatings
When your garage floor shows oil stains, dusty concrete or peeling paint, we grind it, repair the cracks and coat it so it cleans up with a mop.
Polyaspartic Floor Coatings
Polyaspartic cures faster than standard epoxy and holds its color in sunlight, so it helps when you need the garage back quickly or the door stays open a lot.
Metallic Epoxy Flooring
For a bonus room, home gym or showroom where looks matter, metallic epoxy gives a deep, swirled finish, poured over the same careful prep as any other coating.
Urethane Cement Flooring
Urethane cement handles hot water, harsh cleaners and temperature swings better than epoxy, which makes it the right floor for commercial kitchens, breweries and food prep spaces.
Polished Concrete Flooring
If your slab is sound, polishing grinds and hardens the concrete itself into a glossy, low-upkeep floor that fits modern homes, offices and retail spaces in Dublin.
Stained Concrete Flooring
Stain colors the concrete itself, so a patio, entry or interior slab takes on a warm, varied tone without a thick coating sitting on top.
Terrazzo Flooring
Terrazzo sets chips of glass or stone in a binder and grinds them smooth, for lobbies, entries and commercial spaces that need a long-lasting floor with real character.
Basement Flooring
A below-grade room needs a floor that can handle a damp slab, so we test for moisture first and choose the coating or sealer that suits what the test shows.
Concrete Grinding & Surface Preparation
Every floor we put down starts here, grinding off old sealer, glue and the weak top skin of the slab so the new surface bonds to sound concrete.
Concrete Sealing
A sealer helps a Dublin driveway, patio or garage slab resist stains and water, and it's a sensible choice when you don't want a full coating.
Concrete Resurfacing & Overlays
When a slab is worn, flaking or covered in patches but still solid underneath, a thin overlay gives it a fresh, even surface without tearing out the concrete.
Self-Leveling Concrete & Overlays
Self-leveling overlay fills low spots and dips so the slab is flat before tile, wood or a coating goes down, which comes up often in converted garages and remodels.
Pool Deck Coatings & Resurfacing
Pool decks around Dublin homes take sun, chlorine and bare feet, so we repair the cracks and apply a textured, slip-resistant coating or resurface the deck.
Concrete Floor Stripping & Removal
If old epoxy, paint, tile adhesive or carpet glue is in the way, we strip it down to bare concrete so whatever comes next starts clean.

(510) 931-7868What to know before floor work in Dublin
Permits in Dublin come from the city's Building and Safety Division, which handles most construction and repair work in the incorporated city. When a project needs one, the permit decides when we can start, because we won't begin work the city hasn't approved. If a permit applies to your floor, I'll tell you at the estimate, and we'll file it for you or walk you through filing it yourself.
The city also requires every business working inside Dublin to hold a current city business license, and that includes contractors based elsewhere and their subcontractors. We're a flooring contractor based in Castro Valley, CA, so the rule covers us like anyone else, and it's fair to ask any contractor you're considering whether theirs is current. We're licensed and insured, and I'm glad to answer questions about it.
On price, the slab does most of the talking. Its size, how much old paint or sealer has to come off, the cracks that need repair and the system you choose all move the number. The schedule turns on that same prep, the coating's cure time and any permit, which is why I'd rather see the floor in person than guess over the phone.
What you can expect from me and our crew
I do every estimate myself and stay on the job with our crew from the first pass of prep to the final walk-through, so the person who looked at your floor is the one watching the work. That matters because prep disappears under the coating, and it's the part that decides whether the floor holds. If your slab needs more than you hoped, I'll tell you plainly rather than coat it and hope.
We've been doing this since 2017, and I learned it on real floors, one slab at a time. We treat your home or business as someone else's property, because it is, so we cover what needs covering and clean up before we leave. Our promise is satisfaction guaranteed on every job. When you're ready, please call (510) 931-7868 or use our estimate form.
Dublin details that change how we do the floor
A few things come up again and again on Dublin jobs, and each one changes how we plan the prep, which coating we suggest or what has to happen before we start.
Garages that double as rooms
When a garage holds a gym, a workbench or a freezer, everything has to come out before we grind, because we prep the whole slab edge to edge. For a working garage I usually suggest a flake finish in epoxy or polyaspartic over a metallic one, because the flake hides dropped tools, dust and tire marks and gives your feet some grip when the floor is wet.
The water heater stays put
A lot of garages hold the water heater, and the city requires every water heater to be strapped to the wall to protect the water pipes and gas lines in an earthquake. We grind and coat carefully around its base and leave the straps and connections alone. Moving or replacing it is another trade's work, and the city requires a permit to replace one.
New lights or plumbing first
If your garage or backyard shop project also adds lights, outlets or a sink, that part needs its own permit from the city, even in a small detached building the city's list otherwise exempts, and zoning clearance comes before that building goes up. We do the floor, not the wiring or plumbing, so it's best to have those trades finish before we grind and coat.
Business floors that work hard
Shop and business owners here usually call about floors that take carts, spills and daily cleaning. For dry traffic, a commercial epoxy system often fits. For kitchens and washdown areas, I'll steer you toward urethane cement, because hot water and strong cleaners wear on epoxy. We'll talk through when the floor can be out of service so the work fits around your business.
Questions Dublin homeowners ask about floors
Do I need a permit to coat my garage floor in Dublin?
Dublin's no-permit list names painting, papering, carpeting and similar finish work but doesn't name floor coatings, so we confirm it for your job rather than assume. The city's building permits page lists work that does need one, including additions, alterations, electrical and plumbing, so if your project adds any of those, that part needs a permit before work starts.
How long does it take to get a building permit in Dublin?
A permit that needs plan review takes about two to three weeks, or 10 to 15 business days, to process. Most minor permits are issued over the counter. If your floor project turns out to need a permit, we plan the start date around it, so it's worth raising early.
How much does an epoxy garage floor cost in Dublin?
I can't give you a fair number until I've seen your slab, because the price follows the prep it needs. Moisture coming up through the concrete adds work, and a flake system usually costs less than a metallic one. Polyaspartic generally costs more than standard epoxy, which some people accept for the quicker return to use.
Can you coat over peeling garage floor paint?
No, we don't coat over peeling paint, because a new coating is only as strong as what's under it and that paint is already letting go. We grind or strip it down to sound concrete, repair the cracks and then coat, the work described on our concrete floor stripping and removal page.
How do I get my garage ready for a floor coating?
Please clear everything off the floor, including cars, shelving, bikes and anything stored against the walls, because we grind the slab edge to edge. Tell me about any leaks, old sealers or past spills you know of, since those change the prep. Thank you for doing this ahead of time, because it lets our crew start right away.
How soon can I park on a new garage floor coating?
The coating maker's instructions decide when you can walk on the floor and when you can drive on it, and polyaspartic usually gets you back in sooner than standard epoxy. Most of our time on site goes into prep, which varies with the slab, so we'll go over timing once I've seen your floor.
