Epoxy and concrete flooring in San Ramon
San Ramon calls us for two kinds of floors. Homeowners want a garage that cleans up and looks finished, or a patio that's lost its surface, and businesses want office, shop and warehouse floors that hold up to steady foot and cart traffic. We're a flooring contractor based in Martinez, CA, and we come down for these jobs the same way we head over to Walnut Creek or out to Hercules.
The price here comes down to the floor's size, the repair it needs and the system you pick, and the schedule turns on that same repair work plus the coating's cure, so you get your own number once I've looked at the slab. Plenty of the slabs we see are carrying oil stains, hairline cracks or a sealer from years back, and that's where the job really starts, because a coating only holds as well as the concrete under it.
What we do on San Ramon floors
Epoxy Floor Coatings
For workshops, laundry rooms and home gyms on a concrete slab, epoxy gives a hard, washable finish once we've ground and patched the floor.

Offices, shops and warehouses here lean hard on their floors, so we install coatings made for carts, forklifts and cleaning chemicals.

Plenty of San Ramon homes have an attached garage, and we coat it so oil drips and tire marks wipe right up.

When you want the garage back in use fast, polyaspartic cures quicker than epoxy and holds its color in a sunny, open garage.

For a game room, home office or showroom, metallic epoxy gives a poured, marbled look that no two floors share.

Restaurant kitchens and food spaces in San Ramon's shopping centers need a floor that handles hot washdowns, and urethane cement is built for that.

Office and retail spaces here often have sound slabs under the carpet, and we grind and polish them into a low-upkeep floor.

If you've pulled up old carpet and found plain concrete, acid or water-based stain gives it color for less work than a full coating.

Office lobbies and entryways here suit poured terrazzo, stone chips set in resin and ground smooth, for a floor that handles heavy traffic.

Hillside homes here with a lower-level room get a floor we pick after a moisture test, since damp through a slab lifts most coatings.

Most of our time on a job goes here. We grind off sealer, paint and glue so the coating bonds to bare concrete.

Driveways, walkways and patios bake in the inland sun here, and a clear sealer slows the staining and wear on bare concrete.

When a patio or garage slab is pitted and scaled but still sound, an overlay gives it a new surface without tearing it out.

Older slabs with dips and humps get a self-leveling pour, a mix that flattens itself, before tile, wood or a coating goes on.

Backyard pools here mean decks that get wet and sun-baked all summer, so we resurface them with a textured coating for better footing.

Before anything new goes down, we take up old tile, vinyl, the glue under them and peeling coatings, down to a clean slab.

What San Ramon slabs ask of a coating
I started this business in Martinez in 2017, and what I keep seeing is that a peeling floor usually started with a slab nobody tested or ground right. So we put our time into prep, and you hear what we'll do and why before you sign.
I come out to look myself
The person who walks your floor and writes the estimate is me, not a salesperson, and I'm on the job with our crew once the work starts.
Prep before any color goes down
We test the slab and grind it to open, bare concrete before we mix anything, because that step usually decides whether a coating holds or peels.
You know the plan before you sign
I'll walk you through which system fits your floor, what prep it needs and why, so you know what you're paying for before you agree to it.

San Ramon flooring questions
Who issues building permits in San Ramon?
The city's Building & Safety office issues building permits in San Ramon. If your floor job needs one, we sort out with you which office covers your address and who pulls it, and we work with that office from there.
Do I need a permit to redo a floor in San Ramon?
The city's list of permit-free work covers removing and replacing carpet, floor tile or vinyl, unless a termite report, water damage, or framing or subfloor changes are involved. Coatings, polishing and overlays on concrete aren't named on that list, so check with Building & Safety before the work starts instead of assuming. The city also says an exemption doesn't excuse work that breaks the code.
When does a flooring contractor need a license in California?
The state Contractors State License 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. The board lists a job as possibly exempt only when there's no permit, no employee labor and a combined value under $1,000. We're licensed and fully insured.
How much does an epoxy garage floor cost in San Ramon?
The price depends mostly on your garage's size and on how much work the slab needs before any coating goes down. Deep cracks, pitting, old paint or sealer to grind off and moisture coming up through the concrete all add steps, and a full flake system or a polyaspartic topcoat usually runs more than a basic clear coat. I'll give you your number after I've seen the floor, since most of those costs only show once the slab is in front of me.
What causes concrete floors to crack in San Ramon?
Ground movement is a big part of it, and the city's building code addresses expansive soil, clay that swells when wet and shrinks as it dries, as a condition found across San Ramon. That's a citywide finding, not a report on your lot, so we look at your own slab's cracks to see whether they're still moving. A crack that's still moving usually shows back through a coating, and I'll tell you that before we patch it.
How long does a garage floor coating take in San Ramon?
Most of the schedule goes into the slab, not the coating, so it turns on how much grinding and crack repair your floor needs. After that it's the cure, which differs from one coating system to the next. Once I've seen your floor, I'll tell you how long the job runs and how long to keep cars off it.
