Garages, patios and pool decks in Discovery Bay
Discovery Bay sits along Highway 4 in east Contra Costa County, with Oakley and Brentwood just to the west, and it's a short drive out from our base in Antioch. We do the same garage, patio and pool deck work here that we do across those cities, and I still come out to write the estimate myself.
Most calls out here are for single-family houses, starting with the garage and then the patio, walkways and pool deck. So the job usually begins with sorting out which surfaces need a real coating and which only need a good cleaning and a sealer.

Our services in Discovery Bay, CA
- Garage Floor Coatings
Garages here often hold a boat trailer or golf cart, so drips and tire marks build up fast. We grind the slab and lay a flake coating that wipes clean.
- Polyaspartic Floor Coatings
When the garage door stays open for a workshop, daylight hits the floor and epoxy can yellow. Polyaspartic holds its color better and cures faster, so I usually recommend it.
- Concrete Floor Stripping & Removal
Peeling kit coatings rolled over unprepared garage floors are a common call here. We strip them to bare concrete so the new floor bonds to the slab, not old paint.
- Concrete Sealing
Bare patios and driveways here soak up sprinkler water, oil and leaf stains. Concrete sealing slows that down, and we clean the surface first so the sealer goes on evenly.
- Pool Deck Coatings & Resurfacing
Pool decks here take chlorine splash and bare feet, so worn, cracked spots show near the water first. We repair the cracks and resurface with a textured finish that grips.
- Concrete Resurfacing & Overlays
Worn, stained patios and walkways around these houses can usually be resurfaced instead of torn out. We grind, patch and lay a thin overlay for a fresh, even surface.
What Discovery Bay garages and patios have to handle
A garage here does a lot of jobs at once: parking, storage, a workbench, a second fridge. That means hot tires, dropped tools and spilled chemicals, so we match the coating to how you use the space instead of picking it by color. Your price moves with the size of the floor, how much repair the slab needs and the coating you choose, and the schedule turns on that same prep plus cure time, so both go in the written estimate I leave you.
The concrete outside the house asks for something different. Epoxy that works well in a garage can yellow and get slick on a pool deck, so outdoors we use sealers and textured coatings made for water and bare feet.

Discovery Bay flooring questions answered
Who issues building permits for home projects in Discovery Bay?
Contra Costa County does, because Discovery Bay is an unincorporated community the county serves. The Town of Discovery Bay handles water, sewer and parks, while the county building official issues permits for work that builds, alters, repairs or demolishes a regulated structure. You can reach the county's building and planning office at 925-655-2700, and its front counter is by appointment only. If your floor job calls for a permit, I'll tell you at the estimate and we'll settle who gets it before work starts.
Do I need a permit to coat my garage floor in Discovery Bay?
The county's guidance doesn't give a clear answer for floor coatings, so it's worth confirming before work starts. Its list of work on houses and townhouses that needs no building permit names painting, tiling, carpeting and similar finish work, but floor coatings aren't on it, and electrical work such as a panel upgrade does need a permit. When I'm not sure about a job, I check with the county building office before we start.
Does my flooring contractor in Discovery Bay need a state license?
Yes, if the job needs a building permit, uses any extra workers or adds up to $1,000 or more in labor and materials. The California Contractors State License Board licenses anyone who builds or alters a structure in the state, and that $1,000 figure is the one its licensing page gives, so confirm the current amount with the board. We're licensed and insured.
How much does it cost to coat a garage floor in Discovery Bay?
Your price comes from your own slab, and I put it in a free written estimate once I've seen it, because two garages the same size can need very different prep. Grinding, filling cracks, stripping an old coating and dealing with moisture all add work, and a full flake system with a polyaspartic topcoat usually costs more than a single solid color. Call (925) 503-1069 and I'll come out and measure.
How long does a garage floor coating take in Discovery Bay?
Prep and cure time set the schedule more than the coating itself does. A slab that needs stripping or crack repair takes longer up front, and each product has a wait set by its maker before you can walk on it and a longer one before you can park on it. Polyaspartic usually gets you back in sooner than epoxy, and your written estimate lays out how long the garage will be out of use.
What causes a garage floor coating to peel in a Discovery Bay house?
Most peeling starts with prep, when the coating went over concrete that was too smooth, oily or holding moisture, so it never bonded to the slab. A coating can only grip as well as the surface under it. That's why I grind the floor open, clean out the oil and test for moisture before we talk about colors.
