Concrete floor work in Hercules

Hercules has grown since the early 1970s as a place to live, work and shop, and like a lot of California it grew around single-family homes you drive to. That's why so many of our calls here start in the garage, with a slab that's held cars, bikes and storage for years. We also take shop and business floors in town, the same work our crew does at home in Martinez and over in Richmond.

Your price mostly comes down to the floor's size, the finish you pick and how much prep the slab needs. The schedule depends on the grinding and repair, plus the cure before you park on it, and I'll give you your own number once I've seen the floor. On most homes here, that means a garage slab with oil soaked in, old sealer and hairline cracks, and each of those has to come out or get filled before a coating will hold.

What we do on Hercules floors

What Hercules garage slabs ask of a coating

I taught myself floor coatings on my own garage, and since 2017 I've seen that a floor that peels usually started with a slab nobody tested or ground right. So we put our time into prep, and I explain what we'll do and why before you sign.

  • The person who quotes it is there

    I come out myself to look at your floor and give the estimate. Then I'm on the job with our crew for the prep and the install, so nothing gets lost along the way.

  • Prep built for a well-used garage

    Garage slabs here have usually carried cars for years, so we test for moisture, grind out the oil and old sealer, and fill the cracks before the first coat goes down.

  • Reachable after work and on weekends

    Our hours run from 7 AM to 11 PM, seven days a week. That means you can call about your Hercules floor once you're home and can actually look at it.

Hercules flooring questions we hear

How do I find out if my garage floor coating needs a permit in Hercules?

Ask the City's Building Inspection Division at 510-799-8244, because the City's no-permit list doesn't settle floor coatings one way or the other. That list names painting, tiling, carpeting and similar finish work as needing no building permit, but it doesn't name epoxy or polished concrete. If your job needs a permit, 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 add outlets or a floor drain when I redo my garage in Hercules?

Yes, the City requires a permit for electrical, plumbing and mechanical work, so new outlets, lighting or a drain need one no matter how the floor question comes out. Every permit comes with a building inspection, and the City checks that work against the California Building Code and its local rules. Get that work inspected before we coat, so nobody has to cut into a finished floor.

When does a flooring contractor need a California contractor license?

A contractor needs a state license when the job needs a building permit, uses workers beyond the contractor, or costs $1,000 or more in labor and materials together. The Contractors State License Board also requires home improvement contractors to be licensed before they bid, and a bigger job can't be split into pieces under $1,000 to get around the rule. We're licensed and fully insured.

Do out-of-town contractors need a Hercules business license?

Yes, the City requires every organization operating in Hercules to hold a business license. Contractors from out of town skip the City's use permit step and go straight to the business license. Since we come in from Martinez, that's the step that applies to us, and it's a fair thing to ask any contractor you're considering.

How much does an epoxy garage floor cost in Hercules?

Your price comes mostly from the floor's size and how much work the slab needs before any coating goes on. Oil stains, old paint or epoxy, cracks and damp concrete all add grinding and repair time, and a decorative finish like metallic epoxy takes more labor than a plain flake coat. I'll give you a figure for your own floor once I've seen it.

What causes epoxy to peel off garage floors in Hercules?

Peeling usually goes back to prep, a slab nobody tested for moisture or ground properly before the coating went on. Store kits rolled over smooth, oily concrete sit on top instead of bonding, and moisture coming up through the slab pushes them loose. We grind to open the surface, clean out the oil and test the slab before any color goes down.
