Flooring contractor services in Martinez, CA
Stonefield Martinez Epoxy Flooring is a flooring contractor in Martinez, CA for concrete that's peeling, stained or uneven, from garage floor coatings to polished concrete. Price turns on your slab's condition, the grinding and repair it needs and the finish you pick, and timing turns on that prep and the product's cure. Your free on-site estimate gives your price.
Epoxy Floor Coatings
We roll a thick, hard epoxy coating over ground concrete in garages, shops and basements, so the floor stands up to oil, tire marks and scuffs and wipes clean.

We put down heavy epoxy systems for shops, warehouses and service bays that take forklifts, carts and spills, and plan the work around when your floor can close.

When your garage floor is dusting, stained or peeling where the tires park, we grind the slab, fix cracks and put down a flake coating that sweeps clean.

Need your garage back fast? Polyaspartic cures quicker than standard epoxy, and we use it as a full system or as a clear topcoat over epoxy.

Metallic epoxy swirls into a glossy, marbled look, and we pour it in basements, home bars, showrooms and other floors meant to be seen.

What holds up to hot water, steam cleaning and harsh chemicals? Urethane cement, which we trowel onto commercial kitchens, breweries and food plants where epoxy would break down.

We grind your existing slab in steps to a smooth, glossy face, so homes, stores and shops get a hard floor with no coating to peel.
Explore Polished Concrete FlooringStained Concrete Flooring
Stain soaks into the concrete for a mottled, earthy color, and we seal it after. It suits a plain basement, patio or shop floor that needs warmth.

Terrazzo is chips of marble, glass or stone set in an epoxy or cement base and ground flat. We install it in entries, lobbies and kitchens.

Basement slabs often carry moisture up from below, so we test for it first, then pick a coating or sealed finish that can live with it.

Grinding is the prep under every coating, overlay and polish we do. We diamond-grind and patch the slab so the new floor has sound concrete to grip.

Bare concrete soaks up oil and spills, so we apply a penetrating or film-forming sealer to driveways, patios and garage floors to keep stains on top.

Worn, pitted or patched concrete doesn't always need tearing out. We bond a thin cement overlay over a sound slab for a fresh surface indoors or out.

Self-leveling concrete is a pourable mix that finds its own level, so we use it to flatten dipped or uneven slabs before tile, wood or a coating.

Pool decks take sun, chlorine and bare feet, so we resurface cracked or faded decks with a textured finish for better footing when wet.

Before a new floor, the old one has to come off. We grind off coatings, glue and tile adhesive with dust control, and test unknown materials first.

Stonefield Martinez Epoxy Flooring, a flooring contractor based in Martinez
I taught myself floor coatings on my own garage, learned the rest beside experienced crews and started Stonefield Martinez Epoxy Flooring in 2017. We're licensed and fully insured, and we're best known for concrete floors that stay bonded, from home garages to working shops. Read more about us and how we work.

Why Martinez customers choose us
A floor that peels usually started with a slab nobody tested or ground right, so we spend our time on the concrete before any color goes down. I'll tell you what we'll do and why before you sign anything.
The person who quotes runs the job
I look at your floor and write the estimate myself, then I'm on the job with the crew, so nothing gets lost between the quote and the work.
Straight answers about your slab
If your slab has a water problem to fix first, or a simpler finish would serve it better, I'll tell you plainly before you spend money on a coating.
Downtime you can plan around
We tell you up front how long your garage, home or business will be out of use for the product you choose, so you can plan ahead.

Questions we hear most
How much does an epoxy garage floor cost in Martinez, CA?
It depends on your slab, so we price each garage after seeing it at your property. Size, the condition of the concrete, how much grinding and crack repair it needs and the coating system you pick all move the number. Old coating to strip or moisture to deal with adds to it, and a sound slab with a simple flake coat keeps it down.
Why do epoxy floor quotes vary so much between contractors?
Mostly because of prep. Some quotes include a full diamond grind, moisture testing and crack repair, and others roll coating straight onto the concrete, which is usually the floor that peels later. When you compare quotes, ask each contractor how they'll prepare the slab.
How long will my garage be out of use after a floor coating?
That depends mostly on the product, because a fast-curing polyaspartic usually has you walking and parking on it sooner than a standard epoxy, which needs longer to cure. Old coatings or a lot of crack repair can add prep time too. We tell you the downtime for your product before work starts.
Does a flooring contractor need a license in California?
Usually yes, because the state requires a contractor's license whenever a job needs a building permit, uses employee labor or totals $1,000 or more in labor and materials. A bigger job can't be split into smaller ones to stay under that line. We're licensed and fully insured.
Can you put a new epoxy coating over my old peeling floor?
No, the old coating has to come off first, because a new coat holds only as well as whatever it's stuck to. We grind or strip it down to bare concrete and repair cracks before anything new goes down.
Do you guarantee your floor coating work?
Yes, our work is satisfaction guaranteed. Before you sign, the written estimate lays out the prep and finish we'll put down, so you know what you're paying for.
Is epoxy or polyaspartic better for a garage floor?
For most garages we lean toward polyaspartic, either on its own or as a topcoat over epoxy, because it holds its color where sunlight reaches the floor and plain epoxy can yellow. Straight epoxy is still a good, thick choice for basements and shops that don't see sun. I'll recommend one after seeing how you use the space.
Do I need a permit for floor coating work in Martinez, CA?
It depends on the job, and the city's Building Department is the office to ask, since it issues building permits to homeowners and licensed contractors for work inside Martinez city limits. If yours needs one, we sort out with you which city or county office covers your address and who pulls it, then work with that office from there.
