Floors we work on in San Ramon homes and businesses
We're a flooring contractor based in Castro Valley, CA, and San Ramon is one of the cities we work in, along with nearby Pleasanton and Dublin. Many homes here have attached two- and three-car garages, and the garage floor is usually where a homeowner first notices dust coming off the concrete, oil stains or a hairline crack running out from a corner.
On the business side, we see shops, gyms and small warehouses where a floor has to take carts, equipment and steady traffic. Whatever the room, the work starts with the slab. We check it, grind it and repair what we find before any coating goes down, because prep is the part nobody sees and it decides whether a floor holds.

Flooring and concrete services for San Ramon properties
Commercial & Industrial Epoxy Floor Coatings
For shops, warehouses and business floors that take forklifts, carts or steady foot traffic, where we build a heavier coating system on deeper prep.
Garage Floor Coatings
When hot tires, oil drips and road grime have marked up the garage, we grind the slab and lay down a coating that cleans up with a mop.
Polyaspartic Floor Coatings
Worth asking about if you'd like the garage back sooner, since polyaspartic cures faster than most epoxy and holds its color better where sun comes through an open door.
Metallic Epoxy Flooring
For a living space, studio or showroom where the floor is part of the look, with swirled metallic pigment over the same careful prep we give any coating.
Urethane Cement Flooring
Helps in commercial kitchens, breweries and wash-down areas where hot water, cleaners and big temperature swings would wear out an ordinary epoxy floor.
Polished Concrete Flooring
A good choice when your slab is sound and you'd rather have no coating at all, because we grind and polish the concrete itself to a smooth, hard-wearing finish.
Stained Concrete Flooring
Adds color to a patio, interior slab or basement floor without covering the concrete, so the natural mottling still shows through under a protective sealer.
Terrazzo Flooring
For an entry, lobby or business floor meant to last a long time, with chips of stone or glass set in the surface and ground smooth.
Basement Flooring
When a basement slab is cold, damp-looking or cracked, we check it for moisture first and then recommend a floor that suits how the room will be used.
Concrete Grinding & Surface Preparation
The step under every coating we lay, and worth booking on its own when a slab needs grinding clean and flat before tile, wood or another finish.
Concrete Sealing
Helps a driveway, patio or bare garage slab shed water and resist stains when you want protection without changing how the concrete looks much.
Concrete Resurfacing & Overlays
When a patio, walkway or garage slab is pitted and flaking but still solid underneath, a thin overlay gives it a new surface without tearing it out.
Self-Leveling Concrete & Overlays
For uneven or dipped interior floors that need to be flat before a coating or new flooring, since a pourable mix fills low spots that grinding alone can't.
Pool Deck Coatings & Resurfacing
When a backyard pool deck is hot underfoot, slick or cracking, we repair and resurface it with a textured coating that's easier on bare feet.
Concrete Floor Stripping & Removal
Needed when an old peeling coating, glued-down tile or carpet adhesive is in the way, because a new floor bonds only as well as the surface we put it on.

(510) 931-7868What to know before floor work starts in San Ramon
Building permits in San Ramon come from the city's Building & Safety office, and when a job needs one, it has to be issued before our crew starts, so the permit can set the start date more than our calendar does. The city also keeps a list of work that needs no permit, though being on that list never excuses work that breaks the code.
Before you hire anyone, please check two things. California's Contractors State License Board licenses the businesses that build or alter structures, so ask any contractor for their state license. And a business located in San Ramon needs a city business license, plus a Home Occupation Permit if it's run from a home. We're based in Castro Valley, and we're licensed and insured.
If your floor needs a permit, I'll say so at the estimate and file it with the city, or walk you through it if you'd rather file it yourself. Price turns more on the slab than its size, because cracks, an old coating or moisture all add prep, and the system you choose matters too. The prep, the cure time and any permit set the schedule, and the estimate puts price and prep in writing.
What you can expect from me and our crew
I've run this business since 2017, and I got into the trade by grinding and coating my own garage floor. I still 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 making sure the prep matches what we wrote down.
If your slab needs more work than you hoped, I'll tell you plainly rather than coat it and hope for the best. We treat your garage, home or shop as someone else's property, because it is, and we leave it clean. Satisfaction guaranteed on every job. Please call (510) 931-7868 or use our estimate form to set up a visit.
How San Ramon conditions shape your floor project
A few things about San Ramon change how we plan a floor here, from the ground under the slab to the order a bigger project runs in. Here's what each one means for your job.
Expansive soil under the slab
The city's building code addresses expansive soil, the clay kind that swells when it's wet and shrinks as it dries, as a condition found in San Ramon. That's a citywide finding, not a report on your lot, but it's one reason we look closely at cracks here. A coating won't stop a slab from moving, so we fill cracks before coating and tell you if one looks like it's still moving.
Backyard shops and studios
If you're planning a detached shop, studio or storage building, the city requires a building permit once it's more than 120 square feet. At 120 square feet or less it needs none, as long as no electrical or plumbing work is proposed. Adding lights or a sink takes it outside that exemption, so please settle the building's permit before we coat its floor.
Floors inside a larger remodel
When a new floor is part of an addition or remodel, the city's planning staff may need to approve the project before any building permits are issued. That approval comes first, and flooring usually lands near the end of the schedule anyway. Please tell us about the bigger project at the estimate, so we can plan our prep and coating around your other trades.
Pulling up old tile or vinyl
The city's list of permit-free work includes removing and replacing carpet, floor tile or vinyl flooring. That changes when a termite report, water damage, or changes to the framing or subfloor are involved. If we strip old flooring and find soft spots, staining or damage underneath, we'll stop and show you before going further, because that may bring a permit into it.
Questions San Ramon homeowners ask about floor coatings
How much does a garage floor coating cost in San Ramon?
We price each San Ramon garage after seeing the slab, because prep, not the coating itself, is usually the biggest part of the cost. The cracks, stains, old coatings and moisture mentioned above are what move it, along with the system you pick. The written estimate shows the price and the prep for your floor.
Do I need a permit to coat my garage floor in San Ramon?
It isn't settled for every job, so we check yours at the estimate rather than assume. The city's list of permit-free work names swapping carpet, tile or vinyl but doesn't mention floor coatings. You can also ask the city's Building & Safety office, and if a permit is needed, we'll handle it as described above.
Does a flooring contractor in San Ramon need a California state license?
Usually, yes. The state licensing board says a license applies when a project needs a building permit, uses any additional workers, or costs $1,000 or more in labor and materials. It lists a job as possibly exempt only with no permit, no employee labor and a combined value under $1,000, so please ask to see the license before work starts.
How do I get my garage ready for an epoxy floor coating?
Please clear the floor completely, including cars, shelving, bikes and anything stored against the walls, because we grind right up to the edges. Let us know about leaks, drains or spots where water collects, since moisture affects the prep. We handle the grinding, cleaning and repairs, so there's no need to scrub the floor yourself.
How long does a garage floor coating take in San Ramon?
The time comes down to how much prep your slab needs and the cure time the coating maker sets, so we talk it through at the estimate once we've seen the floor. A slab with few cracks and no old coating moves faster than one we have to strip and repair first. Please keep cars off until the maker's cure time has passed.
Can you put epoxy over an old painted or coated garage floor?
Usually not, because a new coating only holds as well as the layer under it, and old paint or peeling epoxy tends to let go. In most cases we grind or strip the old coating down to sound concrete first. I'll tell you at the estimate whether yours has to come off.
