Homes and yards across Concord
Concord is mostly single-family homes, from the older blocks around Todos Santos Plaza out to newer streets on the edges, with shopping centers and business lots mixed in. When we're working here, it's usually on a driveway, a front walk or a back patio that has been down long enough to crack or settle. Now and then it's a wall or a slab for a property owner planning something bigger.
We've been pouring concrete out of Vallejo since 2017, and we do the same work next door in Walnut Creek and Pleasant Hill. On a house that's been here a while, the job usually starts with what's under the old concrete, because that decides whether the new slab holds.

Our services in Concord, CA
- Concrete driveway building
A lot of older Concord driveways have cracked, sunk at the garage or lifted near the street. We break them out, pack a firm base and pour a new slab.
- Concrete sidewalk building
Front walks here often heave once roots or settling ground get under them. Our concrete sidewalk building replaces those sections on packed base with cut joints.
- Concrete patio construction
Back yards in Concord often have a patio that's sinking, pooling water or tilting toward the house. We set the new slab's slope so water runs away from your house.
- Concrete retaining walls
On sloped or hillside lots, old walls often lean or bulge. We pour concrete walls on real footings, with steel rebar inside to hold them together.
- Concrete steps construction
Older front steps tend to crack, chip at the edges or pull away from the porch. We rebuild them with even step heights and steel tied into the landing.
- Slab foundation building
Concord property owners adding a room or a garage need a slab built for the weight. We dig, pack and form the foundation and work around the city's inspections.
What older Concord yards ask of new concrete
When an old driveway or patio here has sunk or broken into pieces, the cause is usually the base. Somebody raked the dirt level instead of digging it out and packing it, so it settled and took the slab down with it. We dig to firm subgrade, the ground the slab actually sits on, pack a gravel base over it and set rebar, the steel bars that keep a cracked slab from pulling apart. That base is buried on day one and it's the first thing people want to trim from the budget, but I'd rather you spend there than on a fancier finish, because a nice surface on soft ground cracks just the same as a plain one.
The other thing we check on every yard is where the water goes, because a slab that falls toward the house sends water at your foundation. Concrete cracks, and I'd rather tell you that now, so we cut control joints, shallow grooves that give it a straight line to crack along, and we keep everyone off it while it cures, the wait while it hardens to full strength.

Concord concrete questions answered
Do I need a permit to replace a concrete driveway or patio in Concord?
It may need one, and the city's permit list doesn't settle it for concrete, so check with the City of Concord Permit Center before work starts. The list for single-family homes and duplexes is a partial one from an older city bulletin, and it names jobs like roofs, water heaters, windows and air conditioning, not concrete. You can use the Permit Center to find which permits a project needs and estimate the fees. We check with the city's building office before we start, and when a permit is needed we can take care of the paperwork.
How do I know if my concrete job needs a grading or encroachment permit in Concord?
If the job moves soil or reaches into the public strip along the street, the city says you apply for separate grading and encroachment permits with its Engineering Division. That can come up when a new driveway meets the sidewalk or a wall cuts into a slope, so it's worth sorting out early. When I walk the job, I'll tell you if I think it's heading that way.
Does a concrete contractor based outside Concord need a Concord business license?
Yes. The city requires a business license to do business in Concord, and that includes state-licensed contractors who work from an office outside the city. It's a fair question to ask anyone bidding your job, us included, since we're based in Vallejo.
When does a concrete contractor need a California contractor's license?
A contractor needs a license from the Contractors State License Board when the project needs a building permit, uses any additional workers or totals $1,000 or more in labor and materials across one or more contracts. Ask for the license before you sign anything. We're licensed and insured.
How can I check if my Concord home is in an earthquake hazard zone?
Type your address into the state's EQ Zapp map, which shows whether a property sits in any of its mapped earthquake hazard zones. It's worth a look before you plan a foundation or a retaining wall. Bring what it shows to the estimate and we'll talk it through.
What affects the cost of a new concrete driveway in Concord?
The biggest things that move the price are the size of the slab, how much old concrete has to come out and how much base work your ground needs. A thicker slab, rebar, a decorative finish and any permit the city requires add to it, while a plain finish keeps it down. The schedule turns on any permit and inspection and on the curing wait before you can drive on it. I'll walk the job with you and give you a written figure.
