Garages, shops and offices across Concord
Concord gives us a wide mix of work. There are older ranch and split-level homes with attached garages and newer houses toward the edges of the city. There are also blocks of shops, warehouses and offices where a floor carries carts and foot traffic all day. We come over from Antioch for that work, the same way we head east to Oakley or up the road to Clayton.
That mix shapes the job. A house slab here has usually been stained, sealed or patched over the years, and a commercial floor has to handle traffic a garage never sees, so the first thing we look at is what's already on the concrete.
Our services in Concord, CA
- Garage Floor Coatings
Many Concord garages hold a car, a workbench and years of oil stains. Our garage floor coatings start with grinding and crack repair so the coating bonds to sound concrete.
- Concrete Floor Stripping & Removal
Older Concord garages often carry a peeling kit epoxy or sealer left by a past owner, and nothing new sticks over it. We strip it back to bare concrete before any new coating goes down.
- Commercial & Industrial Epoxy Floor Coatings
Shops, warehouses and service bays across Concord take forklifts, carts and spills a garage never sees. We match the coating system to that traffic and plan the work around your hours.
- Polished Concrete Flooring
Offices, showrooms and open-plan homes around Concord often have a sound slab hiding under old carpet or tile. We grind and polish that concrete so it becomes the finished floor.
- Concrete Resurfacing & Overlays
Patios and walkways on older Concord lots tend to show pitting, surface wear and mismatched patches. A resurfacing overlay gives that slab a new, even top without tearing it out.
- Pool Deck Coatings & Resurfacing
Pool decks behind Concord homes take bare feet, pool chemicals and constant splashing, so a worn or slick surface shows quickly. We resurface and recoat them with a textured finish made for wet use.
What older Concord slabs need under a new floor
Most garage slabs we see in Concord have had a life before us. A slab might have oil soaked into it, a sealer or kit coating from a past owner, settlement cracks, or moisture coming up from the ground below. Any of those will lift a new coating that goes on top. So we grind the surface open, repair the cracks and test the slab before we talk about colors. When something can't be settled by looking, I'd rather test it first than guess.
That prep is also what moves your price. The cost depends on the size of the floor, how much grinding and repair the slab needs, whether an old coating has to come off and which system you pick. The schedule turns on the same prep, the product's cure time and how soon you need the space back. I come out myself to look at the floor, ask how you use the space and put it all in a written estimate. Then I run the job with our crew, just as we do in Pleasant Hill.

Epoxy, flake and polished floors
Concord flooring questions answered
How much does an epoxy garage floor cost in Concord?
Your price depends on your slab and the finish you choose, so I give you a figure in writing after I've seen the floor. A full flake or metallic system costs more than a clear sealer, and an older Concord garage with an old coating to strip or deep cracks to fill takes more work up front. Call (925) 503-1069 and I'll come look.
Does a garage floor coating need a permit in Concord?
The city's permit list doesn't settle it either way. For single-family homes and duplexes, it names work like roofs, water heaters, windows and air conditioning, not floor coatings. The City of Concord Permit Center gives you a way to find out which permits a project needs. If your job calls for one, I'll tell you at the estimate and we'll settle who gets it before work starts. If I'm not sure, I check with the city first.
Does a contractor from outside Concord need a Concord business license?
Yes. The city requires a business license to do business in Concord, and that includes state-licensed contractors and businesses whose office is outside the city, like ours in Antioch. It's a fair question to ask anyone bidding on your floor.
When does a flooring contractor need a California contractor license?
The Contractors State License Board requires a license when the labor and materials on a project total $1,000 or more. A license is also required when the job needs a building permit or uses any additional workers. We're licensed and insured, and it's worth checking the license of anyone who bids on your floor.
How do I check if my Concord home is in an earthquake hazard zone?
Type your address into EQ Zapp, the state's map tool, and it shows whether the property lies in any of its mapped earthquake hazard zones. That map won't tell us what your slab is doing, though, so at the estimate I still look at the cracks and test the concrete before we pick a system.
What causes epoxy to peel off a garage floor?
Usually it's the prep. The coating went over dirty, oily or sealed concrete with no grinding, so it never bonded to the slab. Moisture moving up through the concrete and hot tires on a thin coat can lift it too. We grind the surface open, test for moisture and remove the old coating before anything new goes down.
