Epoxy Floor Coatings
For a garage, basement or workroom slab that's stained, dusty or hard to keep clean, we grind it and lay down an epoxy coating that wipes up easily.
Flooring Contractor in Oakland, CA - Floors Built on Careful Slab Prep
Castro Valley Epoxy Floors and Concrete is a flooring contractor working in Oakland, CA. We grind, prep and coat concrete in garages, basements, shops and business floors, and we polish, stain, seal or resurface slabs that need it.
Castro Valley Epoxy Floors and Concrete is a flooring contractor based in Castro Valley, CA, and Oakland is one of the cities we serve. We grind, repair and coat concrete for homeowners and business owners here, and we polish, stain, seal, resurface or level slabs when a coating isn't the right answer.
Garage, basement and shop floors across Oakland
Homeowners in Oakland usually call us about garages and basements. A garage slab here has often taken years of oil drips, tire marks and an old coat of paint or sealer that's starting to peel, and a basement floor may be patched in places or out of level. Those floors can look fine in a photo and still need real grinding and repair before anything new goes down, so that's where we start.
Shop and business owners call us about floors that have to work hard, such as warehouses, workshops, kitchens and retail spaces where carts, equipment and spills hit the concrete every day. Those jobs often mean stripping a worn coating before we build a new one. We do the same work in the cities around Oakland, including Fairview, and the slabs we meet there are much like the ones here.

Floor services we offer in Oakland
Commercial & Industrial Epoxy Floor Coatings
For shops, warehouses and production spaces where carts, forklifts and spills hit the floor all day, we build a heavier epoxy system meant to take that traffic.
Garage Floor Coatings
When oil, tire marks and road grime have soaked into your garage slab, we grind it clean and coat it so the next spill sits on top instead.
Polyaspartic Floor Coatings
A good choice when you want your garage back in use sooner, since polyaspartic usually cures faster than epoxy and holds its color better in sunlight.
Metallic Epoxy Flooring
For a basement room, showroom or studio where you'd like a floor with depth and movement, we pour metallic epoxy over a ground and repaired slab.
Urethane Cement Flooring
For restaurant kitchens and food spaces where hot water, grease and cleaning chemicals hit the floor daily, urethane cement handles heat and wet conditions better than standard epoxy.
Polished Concrete Flooring
If your slab is in sound shape, we can grind and polish the concrete itself into a hard, glossy floor with no coating on top to peel later.
Stained Concrete Flooring
For a plain gray slab in a living space or shop, stain adds color that soaks into the concrete, so there's no surface film to wear through.
Terrazzo Flooring
For lobbies, entries and storefronts that want a decorative floor built to last, we install terrazzo with chips set in the binder and ground smooth.
Basement Flooring
Basement slabs can carry moisture up from below, so we check the concrete first and choose a floor system that suits what we actually find.
Concrete Grinding & Surface Preparation
Before any coating goes down, we grind the slab to open its surface and take off old film, because that's what lets a new floor bond.
Concrete Sealing
For bare garage or shop concrete that dusts, stains or soaks up water, a sealer slows that wear when a full coating isn't what you need.
Concrete Resurfacing & Overlays
When a slab is worn, pitted or patched in several spots but still sound underneath, an overlay gives it a fresh, even surface without tearing it out.
Self-Leveling Concrete & Overlays
For uneven slabs that need to be flat before tile, wood or a coating goes down, we pour a self-leveling underlayment to even them out first.
Pool Deck Coatings & Resurfacing
For pool decks that have gone rough, cracked or slick, we repair the concrete and resurface it with a coating suited to wet, bare feet.
Concrete Floor Stripping & Removal
When failing epoxy, paint or old adhesive covers your slab, we strip it down to clean concrete so the next floor has something solid to hold onto.

(510) 931-7868What to check before floor work starts in Oakland
If your project needs a building permit, the City of Oakland's Planning and Building department takes the application, and its Bureau of Building oversees construction work across the city. A permit step has to be done before our crew starts, so it can move your start date. I'll tell you at the estimate if your job needs one, and we'll file it with the city or walk you through filing it yourself.
Two checks are worth making on any contractor here: a California contractor license, which you can look up with the Contractors State License Board, and an Oakland business license, because the city requires everyone doing business in Oakland to file and pay an annual business tax. We're licensed and insured, and we come in from Castro Valley for Oakland work just as we do for San Leandro.
The price mostly follows the slab itself: its size, how much old coating has to come off, how many cracks need repair and which system you choose. The schedule turns on that same prep, on cure time between coats and on any permit step. I put the price and the prep in writing after seeing your floor, so you know what you're paying for before we begin.
The owner on every job, from prep to walk-through
I got into this trade by grinding and coating my own garage floor, and we've been in business since 2017. Prep is the part nobody sees, and it's the part that decides whether a floor holds, so if your slab needs more work than you hoped, I'll tell you plainly at the estimate rather than coat it and hope for the best.
I do every estimate myself, and I 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 slab is the one checking the work. We treat your home or business as someone else's property, because it is, and it's satisfaction guaranteed on every job. Please call (510) 931-7868 or send the contact form to get started.
City steps that can shape an Oakland floor job
A few Oakland rules can change when a floor job starts or what you need in hand first, especially if your project needs a permit or you're fitting out a business space.
A recycling plan comes first
When a job does need a building permit in Oakland, the city asks for an approved recycling plan and a recycling summary report before it issues the permit. That covers what happens to the debris, and because it comes ahead of the permit, it sits at the front of the schedule. If your project needs a permit, we'll plan for this step at the start so it doesn't hold up the work later.
Same-day digital permits
The city's Planning and Building department says it has made applying for building permits easier through same-day digital permits. If your floor project turns out to need a permit, that's worth knowing, because the permit step may not be the long wait some people expect. How your own application goes is up to the city, so I'll talk you through it once I've seen the job.
Zoning before a business build-out
If you're opening or fitting out a shop, studio or warehouse, the city points business owners to its zoning requirements, a zoning clearance permit application and the city zoning map. Zoning is the set of rules for how land can be used, and it's worth settling before you put money into a new floor, because a kitchen or work floor only pays off if the space can be used that way.
City tax for outside contractors
A city FAQ, which carries no date, says businesses based outside Oakland that work in the city owe its business tax, and it lists an $88.00 registration fee for the business tax certificate. That applies to contractors coming in from Castro Valley, too. Because the figure comes from an undated document, the city's business license page is the place to check current terms.
Questions Oakland homeowners ask about floor work
Do I need a permit for an epoxy garage floor in Oakland?
The city's own list doesn't settle it for floor coatings, so it's worth asking before work starts. That list of work needing no building permit names things like fences, small structures and retaining walls, so please don't assume either way. The city's building permits page is where to ask, and I'll give you my read when I see the job.
When does a contractor need a California license for a flooring job?
A state license is required when the project needs a building permit, uses any other workers, or costs $1,000 or more in labor and materials across its contracts. The state board lets some small jobs go without a license, but only with no permit, no employees, a total under $1,000 and no ads claiming to be licensed.
How much does an epoxy garage floor cost in Oakland?
There's no single price, because your slab sets most of it, and I won't quote one without seeing the floor. A bare slab in good shape costs less to prep than one with peeling paint or old epoxy that has to be ground off, and a full flake or metallic system costs more than a clear sealer. Moisture in the slab can add a step.
How long does it take to coat a garage floor?
Most of the time goes into prep and cure, not into rolling out the coating. Grinding, crack repair and the base coat come first, then each coat needs time to cure before the next, and polyaspartic usually cures faster than epoxy. Cars and heavy items stay off until the floor is ready for them, and I'll tell you when that is.
How should I get my garage ready for a floor coating?
Please clear the floor completely, including cars, shelves, bikes and anything stored against the walls, because we grind wall to wall. Let us know about any leaks, old sealers or past coatings you're aware of, since they change the prep. We handle the grinding, repairs and cleanup, and we leave the space clean when we're done.
