Floor coatings and polished concrete in Walnut Creek
Walnut Creek is a short drive from our base in Martinez, and most of the calls we get here are for garage floors in established neighborhoods of ranch houses, for tighter garages in newer townhomes and condos, and for shops, restaurants and offices closer to downtown. Our crew does the same work in Pleasant Hill, Concord and out in Pittsburg, so we know what slabs like these tend to look like.
Most of those garages have years of parking, patching and old sealer on them, so what I find in the slab sets both your price and your schedule. The floor's size, how much has to come off, how many cracks need repair and the system you pick move the price, prep and the coating maker's cure times move the schedule, and the estimate gives you your own figure.
What we do on Walnut Creek floors
Epoxy Floor Coatings
Bare gray garage and laundry slabs in Walnut Creek homes get a ground, primed epoxy coat that cleans up easily and wears hard.

For shops, storefronts and back rooms near downtown, we put down heavier epoxy systems built for carts, foot traffic and cleaning chemicals.

Hot tires, oil drips and dropped tools are what a Walnut Creek garage floor takes. We grind first, then coat for that.
Explore Garage Floor CoatingsPolyaspartic Floor Coatings
Townhome owners with one garage and no other place to park often pick polyaspartic, because it cures faster than standard epoxy.

Metallic epoxy puts a swirled, glossy finish on Walnut Creek showrooms and home offices, poured over a slab we've ground flat.

Restaurant kitchens and food prep rooms in Walnut Creek take hot water, grease and washdowns, and urethane cement is made to handle them.

A sound slab can be ground and polished into the finished floor itself, which suits Walnut Creek offices and retail spaces.

Stain gives patios, entries and the slab floors of remodeled ranch houses color that soaks into the concrete rather than sitting on top.

Terrazzo, chips of stone or glass set in a binder and ground smooth, fits office lobbies and building entries that see heavy foot traffic.

Below-grade rooms get a moisture test before we choose a coating, since water coming up through a slab is what lifts most of them.
Explore Basement FlooringConcrete Grinding & Surface Preparation
We grind the slab's top layer so primer can soak in and grip, which is why it comes first on most floors we coat here.

A clear sealer keeps oil and spills from soaking into a Walnut Creek driveway, patio or garage slab you'd rather keep bare.
Explore Concrete SealingConcrete Resurfacing & Overlays
Worn, stained or patched concrete on older walkways and patios can often be resurfaced with a thin overlay rather than torn out and repoured.

When old tile or carpet comes up and the slab underneath is wavy, a self-leveling overlay brings it flat before the new floor goes down.

Backyard pool decks around Walnut Creek take bare feet, pool chemicals and splash, so we resurface or coat them for grip and easier cleanup.

Peeling epoxy from a past install, old tile glue or paint comes off first, down to bare concrete the new coat can grip.

What Walnut Creek slabs need from a coating
I taught myself floor coatings on my own garage, learned the rest beside experienced crews and started this business in Martinez in 2017. We're known for concrete floors that stay bonded, in home garages and in working shops.
Slabs tested and ground before coating
A floor that peels usually started with a slab nobody tested or ground right, so we put our time into prep before any color goes down.
I come out, and I stay on the job
I look at your floor and give the estimate myself, and when the crew comes for prep and install, I'm working on the job with them.
You know the plan before you sign
Before you sign anything, I walk you through what we'll do to your slab and why, from the grinding to the coating system we'd pick.

Walnut Creek floor questions we hear
Do I need a permit to epoxy my garage floor in Walnut Creek?
The city's permit list doesn't name floor coatings, so check with the Community Development Department before you plan around a permit either way. The city requires a building permit when you add structures or physically change your property, lists work like remodels, re-roofing and replacing windows or water heaters, and says painting and similar finish work needs none. If your job does need one, we sort out with you which office covers your address and who pulls it, and we work with that office from there.
How do I apply for a building permit in Walnut Creek?
You apply through the city's Online Permit Portal, because the city no longer takes paper or emailed applications. To issue the permit, the city needs the signature of the legal property owner or a California licensed contractor.
Can floor work be done on a Saturday or holiday in Walnut Creek?
Construction on a Saturday or a city holiday in Walnut Creek needs an after-hours permit, and the city allows none on national holidays such as Independence Day, Thanksgiving, Christmas and New Year's. We plan the schedule around those days, so if you need the work done over a weekend, tell us when we set dates.
Do I need a permit to redo my driveway or patio in Walnut Creek?
The city says new concrete flatwork on private property, such as a patio, a replaced driveway or a path, needs no permit, but replacing the driveway approach or the sidewalk in front of your house needs an Encroachment Permit. Coating or resurfacing existing concrete isn't named on that list, so ask the city's building staff about your job, and if it needs a permit we'll sort out the rest with you.
How much does an epoxy garage floor cost in Walnut Creek?
The price depends mostly on your slab, so you'll get a real number once I've looked at it on site. What moves it is the size of the floor, how much old coating, sealer or oil has to come off, how many cracks and low spots need repair, and the system you choose, since a metallic or polyaspartic finish costs more than a basic coat.
How long does an epoxy floor take to install in Walnut Creek?
It depends on how much prep your slab needs and how long the coating maker says each coat has to cure before you walk or park on it. Grinding, repairs and old coatings that have to come off add time, and a faster-curing polyaspartic topcoat can shorten it. I'll give you the schedule for your floor at the estimate.
