Concrete flooring jobs in Richmond
Richmond is a big, mixed city, with streets of houses and garages not far from warehouses, shops and working yards near the waterfront. The shipyards once covered much of the industrial land along the South Shoreline harbor, and that side of the city still runs on concrete floors that take real traffic. It's a short drive from Martinez, and we take the same kind of work up the shoreline in Hercules and out in Fairfield.
On the house side we mostly see garage slabs carrying years of cars, oil and patch jobs, and on the commercial side, older floors that have been sealed, painted or coated before. The price turns on that slab and the system you pick, and the schedule turns on how much prep it needs, how long the product cures and whether a permit is involved, so I come out myself to look at the floor and your estimate comes from the slab you actually have.
Flooring work we do in Richmond
Epoxy Floor Coatings
Richmond garages, workshops and laundry rooms get a ground slab, repaired cracks and an epoxy coat built for daily use.

Warehouses and shops on Richmond's industrial side need floors that take forklifts, carts and spills, so we match the system to the traffic.

Many Richmond calls start in the garage, where we grind out oil stains and old patches before a flake or solid coat goes down.

When a Richmond family can't lose the garage for long, polyaspartic cures faster than epoxy and puts you back on the floor sooner.

Garages turned into gyms or game rooms, and Richmond storefronts that want a floor people notice, suit metallic epoxy's swirled, poured look.

Kitchens and wash bays in Richmond that see hot water or harsh cleaners get urethane cement, which takes heat and chemicals better than epoxy.

Older warehouse slabs can often be ground and polished instead of coated, which gives a hard, low-upkeep floor for showrooms, studios and loft-style spaces.

Where a Richmond patio, entry or living room sits on bare concrete, a stain adds color and keeps the look of the slab.

For Richmond lobbies and storefronts that want a dressier floor, we lay epoxy terrazzo with stone or glass chips ground smooth.

Basements and lower floors in Richmond get a moisture test first, because a coating over a damp slab is the likeliest to lift.

Diamond grinding opens up the slab and takes off old sealers and stains so a coating grips, and it's where we spend the most time.
Explore Concrete Grinding & Surface PreparationConcrete Sealing
Richmond driveways, walkways and shop floors get a sealer that keeps oil and water from soaking in, a lighter step than a full coating.

Worn, flaking or patched concrete on older Richmond properties can often be resurfaced with an overlay instead of torn out and poured again.

Uneven slabs in older shops and remodels get a self-leveling layer that flattens the surface, so tile, vinyl or a coating lays down true.

Backyard pool decks in Richmond that have cracked or gone slick get resurfaced with a textured coating that's easier on bare feet.

Older Richmond garages often carry old paint or a failed epoxy, and we strip it down to clean concrete so the new floor bonds.

What Richmond garages and shops ask of a floor
I taught myself this trade on my own garage and started the business in Martinez in 2017. What sets us apart is where we spend our time, on the slab under the coating, and I'll tell you what we'll do and why before you sign.
I look at your floor myself
I come out myself to look at the slab and give you the estimate, and I'm on the job with our crew while they prep and install.
Slab prep before any color
Garage and shop slabs here have often been oiled, patched or coated before, so we test the concrete and grind it open until a new coat can grip it.
Straight answers before you sign
I'll walk you through what we'll do to your floor and why before you sign anything, including what we found in the slab and how it changes the plan.

Richmond flooring questions we hear
Do I need a building permit to coat a garage floor in Richmond, CA?
A permit is likely needed for any Richmond project that isn't on the city's list of work exempt from permits, and that list names painting, tiling, carpeting and similar finish work, not floor coatings by name. The city's Building Division issues building permits, which are required before you alter, repair or improve a building, so check your scope with them before work starts. If your job needs one, we sort out with you who pulls it and work with the city from there.
Do I need to contact the Richmond Permit Center for a kitchen or bathroom floor?
Yes, the city's exempt-work handout asks owners to contact the Permit Center when tiling, carpeting or similar finish work is in a kitchen or bathroom. Those rooms usually have plumbing and electrical close by, and unless the handout exempts it, that work needs its own separate permit. I'd rather you ask first than have the floor held up later.
Who can pull a building permit in Richmond, the homeowner or the contractor?
Either one can, because the city issues permits to property owners or their authorized agents and to licensed contractors. A contractor registering for a permit has to show a Contractor's State License Card, a workers' compensation insurance certificate and a current City of Richmond business license. We're licensed and fully insured.
How long does it take to get a building permit in Richmond, CA?
Simple jobs can be quick, because the city says most single-trade permits and residential remodels that need no drawings are issued as soon as it receives and verifies the application documents. Larger scopes take longer. Applications go in electronically, and if you can't apply online, the city takes them in person by appointment.
How much does an epoxy garage floor cost in Richmond, CA?
The cost comes from your slab and the system you choose, so I give you the number after I've seen the floor in person. Size sets the base, and cracks, oil-soaked spots, old paint or coating that has to be stripped and heavy grinding all add to it. A solid-color epoxy usually costs less than a full flake or metallic finish, and a polyaspartic topcoat costs more but gets your garage back sooner.
What causes epoxy garage floors to peel in Richmond?
Peeling usually starts with the slab, not the coating, when nobody tested the concrete or ground it open before the coat went on. A kit rolled over smooth, oily concrete or an old sealer just sits on top, and moisture coming up through the slab can push it loose. That's why our time goes into prep first.
