Antioch, where driveways carry more than cars
Antioch sits at the east end of Contra Costa County along the river, with a downtown near the water and neighborhoods of single-family homes spreading south toward the hills. It's a longer drive for us than Concord, but the calls are much the same kind, mostly homeowners whose driveway has cracked, whose patio has sunk at one corner or whose garage floor has gone uneven.
What stands out here is how hard the concrete gets used. Driveways, side yards and garage floors often hold trucks, trailers and boats, so we treat the base and the steel underneath as the main part of the job.
Working in Antioch: permits, licenses and what moves the price
In Antioch, building permits come from the city's Building Services Division, which also inspects the work, so when a job needs a permit, the city's review has to happen before we can set a pour date. Before you hire anyone, check two things: a California contractor license and a current City of Antioch business license, which the city requires of everyone working here, subcontractors included. We're licensed and insured, and we figure out early whether your job reaches the street or needs a city or county sign-off, then handle the application and paperwork when one's needed.
We're a concrete contractor based in Walnut Creek, and Antioch is a straight run out Highway 4 from us, close enough that I come out to every estimate myself. We run jobs here the same way we do in Pleasant Hill or Berkeley, with our own crew from prep to finish. Your price mostly turns on what's under and around the slab: how much old concrete comes out, how much base the ground needs, how close the truck can get and the finish you pick. The schedule turns on permits and weather, and the written estimate I put together gives you your own figure.
What do Antioch driveways and yards need most?
Antioch gets only about 13 inches of rain in an average year, so most of the time a slab here sits in dry air and full sun, and concrete that dries too fast while it's curing, the days when it's still gaining strength, ends up with a weak, dusty top that chips. We set pours for the cooler morning hours and keep the surface damp while it cures, because that early wait decides how hard the slab gets.
The other things we see are weight and slope. A lot of houses here park a work truck, a boat trailer or an RV beside the garage, and plenty of backyards climb toward the hills, so a slab has to be built for the load it'll carry and the water running onto it. I'd rather spend an extra hour working out where that water goes than guess and pour.

Concrete work we do in Antioch
Concrete driveway building
Many Antioch driveways carry trucks and trailers, not just cars. We dig out, pack a solid base and add steel sized for that weight.
Concrete patio construction
Backyard patios here sit in full sun most of the year. We pour early, slope them away from the house and pick a finish with some grip.
Garage floor concrete
A garage floor in Antioch often doubles as a workshop or a spot for the boat. Our garage floor concrete work starts with a level, packed base.
Concrete retaining walls
Sloped backyards are common where Antioch climbs toward the hills. We build concrete retaining walls with drainage behind them, because trapped water is what pushes a wall over.
Concrete pool decks
Pool decks here bake through long dry summers and get splashed all season. We slope them toward drains and give them a textured top for bare feet.
Concrete cutting
Adding an RV pad or a walkway often means cutting into an existing slab. We saw clean lines so the new pour meets the old one neatly.

Tell us what you need at (925) 448-9528 or through the form. We'll set a time for me to come out to your house in Antioch.
I walk the site with you
I look at the slab, the slope and where the water runs, and I ask a lot of questions about how you use the space. It helps if you're home so you can show me the problem spots, and everything that moves the price goes into a written estimate.
Paperwork first, then the pour
We sort out any permit and get the ground marked or scanned before anyone digs, and if the city has to review the job, that review comes before the pour date. Then our crew preps the ground, pours and finishes, and I'm on site for the parts that matter most.
Walk the finished job together
When the work's done, I walk it with you and go over how to look after the new concrete. You'll know what to keep off it while it cures and what to watch for after.

Questions about concrete work in Antioch
Do I need a permit for a concrete patio or retaining wall in Antioch?
Most residential concrete flatwork, the flat pours like patios and walkways, is on the city's permit-exempt list, and so are retaining walls three feet tall or less. The word "most" leaves room, and a taller wall isn't on that list, so we check your job against it before we schedule anything. On a close call, the city's building staff has the final word.
Does replacing my driveway apron in Antioch need a separate permit?
Yes, any work in the public right-of-way, including curb cuts and driveway changes, needs an Encroachment Permit from the city's Engineering Division, separate from any building permit. If your new driveway reaches the curb or changes where it meets the street, that counts, and the application can go through the city's online permitting system. We put it on the schedule early so the timing is clear from the start.
When does a concrete contractor need a California state license?
Under the Contractors State License Board rules, a contractor needs a license when the project needs a building permit, uses any extra workers, or costs $1,000 or more in labor and materials, counted across all the contracts on that project. That covers nearly every driveway or patio job, so ask anyone you're considering for their license before you sign.
How much does a new concrete driveway cost in Antioch?
I can give you a real number only after I've seen your driveway, because what's under the old slab and how much of it has to come out move the price more than size alone. The one place I won't cut is the subgrade, the ground the slab sits on, which we dig out and pack instead of raking level, since a nice finish on loose dirt settles and cracks along with it. If the budget's tight, I'd rather simplify the finish than thin the base, and I'll lay out both choices on the estimate.
What causes new concrete to crack?
Concrete shrinks as it dries, so some cracking is normal, and the real job is deciding where it happens. We cut control joints, shallow grooves that give the slab a straight line to crack along, early enough that the slab doesn't pick its own spot, and we set rebar, steel bars that hold the pieces together if a crack opens. The other big cause is a base that was never packed, which is why we spend our time down there first.
How long does a new concrete driveway take before I can drive on it in Antioch?
You can walk on new concrete well before you can drive on it, and I'll give you both waits for your slab before we pour, since the weather that week plays a part. You're without the driveway from the day we break out the old slab until the new one has cured enough to take a car, so if parking is tight on your street, we plan the start date around that.
