Homes, condos and shops across Walnut Creek
Walnut Creek has a bit of everything we work on. There are single-family houses with attached garages, townhomes and condos with shared parking and storage, and a downtown full of shops, restaurants and offices. We've been based in Antioch since 2013, and we do the same work here that we do next door in Pleasant Hill and Concord.
What usually shapes the job here is what's already on the slab. A garage floor that's been painted, sealed or soaked in oil over the years has to be ground clean before anything new will stick, so that's the first thing I look at.
Our services in Walnut Creek, CA
- Garage Floor Coatings
Most Walnut Creek garages we see are bare, stained concrete holding cars and a workbench. We grind the slab, fill cracks and lay a coating that handles hot tires.
- Polished Concrete Flooring
Downtown shops and offices often want a floor that's simple to mop and doesn't peel. Our polished concrete flooring grinds and hardens your existing slab to a glossy finish.
- Concrete Floor Stripping & Removal
Many garages here carry old paint, sealer or a failed coating. We strip it to clean concrete first, because a new floor only holds as well as what's under it.
- Polyaspartic Floor Coatings
Townhome and condo owners often can't leave a garage out of use for long. Polyaspartic coatings cure faster than standard epoxy, so the space comes back sooner.
- Commercial & Industrial Epoxy Floor Coatings
Restaurants, retail backrooms and service shops take foot traffic, carts and spills every day. We put down epoxy systems built for that wear and plan around your hours.
- Concrete Sealing
Plain concrete patios and garage slabs here soak up oil, water and leaf stains. We clean the surface and seal it so spills wipe up instead of setting in.
What Walnut Creek slabs ask of a new floor
A lot of the garages we see here have been lived in hard, with oil, old paint or a hardware-store sealer sitting on the concrete. Concrete can also carry moisture up from underneath that pushes a coating off later, and you can't tell that by looking, so I grind and test before we ever talk about colors. That prep is usually what moves the price most, along with the size of the floor and the system you pick. The schedule turns on what the testing shows and how long the product needs to cure, and you get a written estimate after I've seen the slab.
Storefronts, offices and condo buildings bring their own limits, with neighbors close by and businesses that need to stay open. We grind with vacuums hooked to the machines to keep the dust down, and we plan the work so you lose as little use of the space as we can manage.

Walnut Creek floor questions answered
Do I need a permit for an epoxy garage floor in Walnut Creek?
The city's permit list doesn't settle it for a floor coating, so we find out before any work starts. Walnut Creek's Community Development Department issues permits and requires one when you add structures or physically change your property, and its list names jobs like remodels, re-roofing and replacing windows while saying painting and similar finish work don't need one. A floor coating isn't named either way, so if your job calls for a permit I tell you at the estimate and we settle who gets it, and if I'm not sure, I check with the city first.
How do I apply for a building permit in Walnut Creek?
You apply online, because the city takes every permit application through the portal on its building permits page and no longer accepts paper or emailed ones. The permit is issued once the legal property owner or a California licensed contractor signs for it. We're licensed and insured, and when a floor job needs a permit, we decide at the estimate which of us applies.
Can a flooring crew work on a Saturday in Walnut Creek?
Only with an after-hours permit, because the city requires one for construction on Saturdays and city holidays. No construction is allowed at all on national holidays such as Independence Day, Thanksgiving, Christmas and New Year's. If a Saturday is the only time your garage or shop can sit empty, tell me at the estimate so we can plan the schedule around it.
How much does a garage floor coating cost in Walnut Creek?
Your price comes from the size of the floor, how much prep the slab needs and the system you choose, and I give it to you in a written estimate after I've seen the slab. Grinding off old paint or sealer, filling cracks and dealing with moisture all add work, while a single-color coat costs less than a full flake or metallic floor. I'd rather test the concrete first than quote a number that changes once we start.
What causes epoxy garage floors to peel?
Most peeling comes from prep, when a coating goes over dirty, sealed or painted concrete it can't grip. Moisture coming up through the slab and hot tires on a thin, poorly bonded coat cause most of the rest. That's why we grind down to open concrete and test the slab before anything goes on it.
Does my HOA need to approve a garage floor coating in Walnut Creek?
Your association's rules decide that, so read them or ask your property manager before we book the job. Some associations set work hours, noise limits or rules for contractors in shared garages and driveways. If yours wants details from us, like the product or the schedule, ask at the estimate and we'll give you what they need.
