Request an estimateSan Ramon: graded lots and expansive soil
San Ramon is mostly single-family neighborhoods spread over graded hills, with older streets on the west side near 680 and newer subdivisions east through Dougherty Valley, plus office parks in between. Most homes have attached garages, and plenty of backyards have a patio or pool deck that's seen a lot of summers. The houses and lots look a lot like Danville next door, and the floors we get asked to fix are much the same.
The ground matters more than the house. An earlier version of the city's building code called out expansive soil, clay that swells when it's wet and shrinks as it dries, as a condition found across San Ramon, though that's a citywide finding and not a report on your lot. On a slab it usually shows up as cracks that open and close with the seasons, so we deal with the cracks before any coating goes down, or the new finish just cracks along the same lines.
What I check before we start a San Ramon floor
In San Ramon, building permits come from the city's Building & Safety office, and whether a floor job needs one is their call, not ours. I check with them before we start, and when a permit is needed, we handle the paperwork as part of the job, so the city's review is what sets the start date. Before you hire anyone, make sure they hold a state contractor license, and if they're based in San Ramon, the city requires a city business license too. We're licensed and insured.
We're based in Dublin, right next door, and we work the same kinds of garages and patios in Pleasanton, so San Ramon slabs don't surprise us. What moves the price here is mostly prep: how many cracks need filling, whether old sealer or paint has to come off, and how big the floor is, along with the finish you pick. The schedule turns on the city's review when a permit is needed and on cure time between coats, and your written estimate after I've seen the floor gives you your own figure.
Services in San Ramon, CA
Garage Floor Coatings
Garages here usually show hairline cracks and oil stains from years of daily parking. We grind the slab, fill the cracks and put down a coating that hoses clean.
Concrete Grinding & Surface Preparation
Many slabs here carry old sealer, paint or carpet glue from earlier owners. We grind to clean, open concrete, because coatings don't bond to leftovers.
Concrete Resurfacing & Overlays
Patios on clay ground tend to crack and lift over time. We grind the high spots, patch the breaks and lay an overlay that gives you one even surface.
Pool Deck Coatings & Resurfacing
Pool decks here take hot sun and chlorine all summer, so old finishes fade and flake. We strip what's failing and resurface with a slip-resistant coating.
Concrete Sealing
Patios here go from dry summers to wet winters, so bare concrete stains and flakes. We clean and seal it so water beads up instead of soaking in.
Commercial & Industrial Epoxy Floor Coatings
Offices and shops here can't close for long to redo a floor. We plan commercial and industrial epoxy floor coatings around your hours so most of the work happens while you're closed.

Frequently asked questions
Do I need a permit to redo my floors in San Ramon?
Removing and replacing carpet, tile or vinyl needs no permit in San Ramon unless there's a termite report, water damage, or changes to the framing or subfloor, according to the city's list of permit-free work. Coating or polishing concrete isn't on that list, so I check with the city before we start, and if a permit is needed, we take care of the paperwork. Even permit-free work still has to meet the code.
When does a flooring contractor need a license in California?
Under the Contractors State License Board, a contractor needs a state license when the job needs a building permit, uses any additional workers, or costs $1,000 or more in labor and materials together. The board treats only a job with no permit, no employee labor and a combined value under $1,000 as possibly exempt. You can look up any contractor with the board before you sign.
How much does a garage floor coating cost in San Ramon?
Most of the price on a San Ramon garage comes from prep, not the coating, so I won't give you a number until I've seen the slab. Size matters, but cracks to fill, old sealer or paint to grind off, moisture in the concrete and the system you pick, such as a flake epoxy or a faster-curing polyaspartic, move it more. Once I've looked at it, the written estimate breaks that out.
What causes an epoxy garage floor to peel?
Usually it's the concrete under it, not the epoxy. A slab that wasn't ground, still had old sealer or oil in it, or had moisture coming up through it won't hold a coating for long. That's why I'd rather spend the time grinding and checking than rush to the fun part.
How do I know if my concrete is ready for a coating?
A slab is ready when it's sound, clean, dry enough and free of old sealer, and the only reliable way to tell is to look at it in person. If yours isn't ready because of a crack that's still moving or moisture coming up, I'll tell you straight and tell you what it needs first, even if that means waiting.
Can you redo an office or shop floor in San Ramon without closing the business?
Usually, yes, if we plan the work around your hours. We work out prep, install and cure time against your schedule before we start, so you know when the floor is out of service. How much downtime you need comes down to the floor's size and the system you choose.
