Antioch driveways, patios and back yards we work on
In Antioch, the calls we get are usually about concrete people use every day, like a driveway cracked across the middle, a patio that's dropped away from the back door or a front walk with an edge that catches your toe. It's a big, mostly residential city with shopping centers and small commercial lots mixed in, and the work looks a lot like what we do next door in Pittsburg.
Plenty of back yards here are reached only through a side gate, so we plan how the concrete gets back there, by wheelbarrow, pump or chute, before the pour, along with how much old slab and dirt has to come out.
Concrete services for Antioch homes and lots
Concrete driveway building
When an Antioch driveway has cracked through or settled at the garage lip, we tear it out, dig to firm ground, pack a new base and pour again.
Concrete patio construction
An Antioch patio gets lived on, so we set it to drain away from your back door and cut joints where the slab will want to crack.
Stamped concrete services
Stamped concrete gives a patio or walk the look of stone or brick, and we seal it so the color fades more slowly in the Antioch sun.
Concrete sidewalk building
We replace front walks that have lifted or split, often from a tree root, and give the new one a broom finish, a swept texture for grip.
Garage floor concrete
A cracked or stained Antioch garage floor can be broken out and repoured, and we pitch it slightly toward the door so wash water and drips don't sit.
Decorative concrete
Color, scoring or exposed aggregate, where the top is washed to show the stone, can dress up an entry, and I'll explain how each one wears.
Concrete retaining walls
Where an Antioch back yard climbs into a slope, a poured retaining wall with drainage behind it holds the dirt back and gives you flat ground to use.
Concrete floor installation
We pour interior slabs for shops, workrooms and add-ons over a packed base and a moisture barrier, flat enough for flooring or equipment to sit right.
Concrete pool decks
Pool decks here take hot sun and wet feet, so we use a finish with grip and slope the deck so splash water runs away from the pool.
Concrete steps construction
Front steps that cracked or pulled away from the house get rebuilt with rebar, steel bars that hold the concrete together, and even step heights.
Slab foundation building
For an Antioch addition, garage or backyard unit, we form and pour the slab foundation on a dug-out, packed base so the walls go up on solid ground.
Foundation installation
When a new structure needs more than a slab, we set footings and foundation walls to the plans and keep the steel where the engineer drew it.
Concrete parking lot building
For small Antioch commercial lots and shared driveways, we pour thicker sections where trucks turn and slope everything to the drains so water doesn't pool.
Concrete footings
Footings are the buried concrete under a deck post, wall or patio cover, and we dig them to the plans so the weight spreads into firm ground.
Foundation raising
When part of a house or slab has dropped, foundation raising lifts it back toward level, and I'll tell you what likely caused it before we start.
Concrete cutting
We saw clean openings in old slabs for a new drain line, a doorway or a patch, and we use water on the blade to keep dust down.

Working in Antioch: permits, licenses and what we check
Building permits in Antioch come from the city's Building Services Division, which also inspects the work, so when a job needs a permit, the city's review and inspections set part of the calendar. Before you hire anyone here, it's worth checking two things, a current state contractor's license and a current City of Antioch business license, which the city requires of everyone doing business there, subcontractors included. We're licensed and insured, and before we set a date we check with the city about what your address and your job call for.
We come out from Concord on Highway 4, and an Antioch job is priced the way ours are in Vallejo or back home, by the size of the slab, how much old concrete we break out and haul away, how much digging and base the ground needs, whether the truck can reach or we need a pump, and the finish you choose. The schedule turns on the permit if there is one, the weather and the curing time, the wait while concrete gains strength before you use it, and the written estimate I give you after the visit lays out the price and the steps for your job.
Why Antioch slabs crack, chip and hold water
Antioch is dry, averaging a little over 13 inches of rain a year, with warm afternoons, and that dries the top of a fresh slab faster than the inside. When that happens the surface can come out weak and dusty and start chipping, so we pour early in the day and keep the new concrete damp and covered while it cures.
The other thing we see is water running the wrong way, a patio or driveway that falls toward the house and leaves a puddle at the foundation after a storm. Before we form anything, we check where water comes off your roof and yard, then slope the new slab to carry it away.
How a concrete job goes when you call us in Antioch
From your first call to the final walk-through, here's how a job with us runs and what you'll be asked to do along the way, which isn't much.
Call or send a message
You call (925) 536-0945 or send the form, and we get back to you to set a time for me to come out. Tell us what's there now and what you'd like, and that's enough to start.
Walk the site with me
I look at the old concrete, the slope and the access with you, explain your choices and which ones cost more or less, and put the estimate in writing. Try to be home for this visit, because it's where your questions get answered before anything is decided.
Permits, then the pour
We check with the city for your address and handle the permit paperwork if one is needed, and when there is one, its review and inspection come before the pour date. I'm on site with our form setters and finishers for the work itself.
Walk the finished job together
When the work's done, we walk it with you, and I tell you when you can walk on it, when you can drive on it and how to look after it. Satisfaction guaranteed on every job.
Questions about concrete work in Antioch
Do I need a permit for a new concrete driveway in Antioch?
You may, and the street end is the usual reason, because any work in the public right-of-way, curb cuts and driveway changes included, needs an encroachment permit from the city's Engineering Division. For the rest of the driveway, the city lists most residential flatwork, the flat pours like driveways and patios, among projects exempt from a building permit, and we confirm your job with the city before we pour.
Does a concrete retaining wall need a permit in Antioch?
The city lists retaining walls three feet tall or less among projects that don't need a building permit. A taller wall isn't on that list, so we take your wall to the city's building staff before we design it.
When does a concrete contractor need a state license in California?
The Contractors State License Board requires a license when the job needs a building permit, uses any additional workers, or costs $1,000 or more in labor and materials. That total counts every contract on the project, so splitting the work into smaller contracts doesn't get around it.
How do I apply for a building permit in Antioch?
Owners and contractors can apply online through the city's online permitting system. When we're your contractor, that part is ours, and you'll know from us whether your job needed one.
How much does a new concrete driveway or patio cost in Antioch?
I can't give you a fair number without seeing the site, so I come out, look at it with you and write it up. The base is the part people want to save on first, because nobody sees it once the slab is down, and I'd drop a stamped or colored finish before I'd skimp there, since a nice surface on a poorly packed base sinks and cracks with the dirt under it.
What causes concrete driveways to crack, and will my new one crack too?
Concrete shrinks as it dries, so some cracking is normal, and the goal is to choose where it happens. We cut control joints, straight grooves that give the slab a weak line to crack along out of sight, and we dig out and pack the base so the slab doesn't settle and break, which is what usually cracked the old one.
