Concrete work for Pleasant Hill homes and lots
The short answer: Yes. C&K Pittsburg Concrete Company is a concrete contractor based in Pittsburg, CA, and we take driveway, patio, walkway, garage floor, retaining wall and foundation jobs in Pleasant Hill. I come out to look at each job myself, and I'm on site with our crew when we do the work.
In Pleasant Hill, a lot of what we're called to look at sits in established neighborhoods, where the driveway, the back patio and the walk to the front door have been there a long time and it shows. Cracks run across the driveway, a patio tips toward the house, or a garage floor holds water after it rains. We also hear from owners of rentals and small shops who need a parking area or an entry redone. It's the same work we do next door in Concord and Walnut Creek.
Older slabs change the job. Before I price a replacement, I want to know how thick the old concrete is, whether there's steel in it and what it's been sitting on, because that decides how much comes out and how much base we rebuild before the pour.
Clay ground and aging slabs on Pleasant Hill properties
The city has pointed to clay soils being common throughout Pleasant Hill. Clay swells when it's wet and shrinks as it dries, so a slab poured on dirt that was only raked level moves with it, and that's where a lot of the cracking and sinking we see starts. That's a citywide picture, not a test of your yard, so I look at your ground on the first visit. Our fix starts with the subgrade, the dirt the slab sits on. We dig out the soft material, pack a solid base and slope it so water runs away from the house instead of under it.
The other thing we see is age. Older driveways and walks often have little or no rebar, the steel bars inside a slab that hold it together once it cracks, and roots, water and heavy cars have had years to work on them. When a section is past saving, we cut it out cleanly rather than patch over it, because a patch on a slab that's still moving usually cracks again.
Concrete services we offer in Pleasant Hill
Concrete driveway building
When your driveway has cracked, sunk or started holding puddles, we tear it out, rebuild the base and pour a new one that sheds water.
Concrete patio construction
For a backyard patio that's tipped toward the house or gone uneven, we break it out and pour a new one sized for how you use the yard.
Stamped concrete services
Stamped concrete gives a patio, walkway or pool deck the look of stone or brick, poured in one piece so there are no loose pavers to reset.
Concrete sidewalk building
When a walkway section lifts or drops enough to catch a toe, we cut out the bad panels and pour new ones that line up.
Garage floor concrete
When your garage floor is cracked or slopes the wrong way, we replace it so water runs out the door and it carries cars and shelving.
Decorative concrete
Decorative concrete covers color, exposed stone and custom borders, for when you want an entry or patio to match the house instead of looking like a parking pad.
Concrete retaining walls
On a sloped lot, a concrete retaining wall holds the hill back and gives you flat ground, with drainage behind it so water doesn't push on it.
Concrete floor installation
For an addition, a workshop or a small business space, we pour concrete floors level so whatever goes on top sits flat.
Concrete pool decks
Around a pool, the deck has to drain away from the water and feel right under bare feet, so we pick a finish with grip that isn't rough.
Concrete steps construction
Front or back steps that have cracked, settled or pulled away from the house can be rebuilt with every step the same height, so nobody's caught off guard.
Slab foundation building
When you're adding a room, a garage or an accessory unit, we build the slab it sits on, with the base and steel set before the pour.
Foundation installation
For a new building or a replacement under an older one, we dig, form and pour the foundation to the engineer's plans.
Concrete parking lot building
For shops, rentals and small lots, we rebuild broken-up parking areas thick enough for daily traffic and graded so rain runs off instead of pooling.
Concrete footings
Footings are the buried concrete that carries a wall, a post or an addition, and we dig and pour them to spread that weight into firm ground.
Foundation raising
If doors stick, floors slope or cracks are opening in the walls, a settled foundation may be the cause, and we can lift it back toward level.
Concrete cutting
We saw openings into old slabs and walls for doors, drains and repairs, checking for steel and pipes inside first so we don't cut into a surprise.

Permits, licenses and pricing for Pleasant Hill concrete jobs
Permits for work in Pleasant Hill go through the city's Permitting Office, and the Building Division requires a permit for any work that physically changes or adds structures to a property. When a job needs one, the city's review sets part of the schedule, so we check with them early in planning, walk you through what they tell us and pull the permit ourselves. Two things are worth checking on any contractor here. The state requires a contractor's license, and the city requires its own business license from contractors working in Pleasant Hill, even ones based in another city like us. We're fully licensed and insured.
Pleasant Hill sits along Interstate 680 in the middle of the county, so the run from Pittsburg is short, and that matters on pour day because concrete starts setting in the truck. We make the same kind of run for jobs in Martinez. What moves your price is how much old concrete comes out, how much base work your ground needs, the size and thickness of the slab, how easy the site is to reach and the finish you pick. The schedule turns on any permit, the weather on pour day and curing, the days the concrete needs to harden before it can take your weight or your car. Your estimate spells out what's included and what isn't.
What to expect when you call us in Pleasant Hill
Here's how a concrete job in Pleasant Hill goes with us, from the first call to the final walk-through, and where the city's rules fit into it.
- Step 01
Call or send the form
Tell us what you're seeing, like cracks, a sinking corner or water pooling by the house. We set a time for me to come out, and it helps if you can be there so I can ask my questions.
- Step 02
I walk the site with you
I look over the old slab, the ground and where the water goes, and I ask a lot of questions so I'm not guessing. You get a written estimate that says what's in it and what isn't, so you know what you're paying for before anything starts.
- Step 03
We pour inside city hours
The city allows construction from 7:30 a.m. to 7:00 p.m. on weekdays and 9:00 a.m. to 6:00 p.m. on weekends. I run the pour with our crew early in that window when we can, because afternoon heat dries the top too fast and can leave it weak and dusty.
- Step 04
We clean up and walk it
When the work's done, we clean up and walk the finished job with you. I'll tell you when the curing is far enough along to walk on it and when it's ready for a car.
Pleasant Hill concrete questions we hear most
How do I find out if my concrete project in Pleasant Hill needs a permit?
Call the Building Division at (925) 671-5200, which is what the city tells people to do when they're not sure. If the work touches the street, curb or gutter, like where a driveway meets the street, the city says it may also need an encroachment permit, a permit for working on city property, through the Engineering Division. We ask these questions early, so you'll know before we set a pour date.
Does a shed on a concrete slab need a permit in Pleasant Hill?
A one-story detached shed with 120 square feet of floor or less doesn't need a building permit in Pleasant Hill, but the city still requires a Planning Zoning Permit for it. If the shed will have electricity, the city wants a building permit. We size the slab to the shed you're buying and pack the base so it sits flat.
Does my concrete contractor need a California state license?
Yes, if the job costs $1,000 or more in labor and materials together, needs a building permit or uses any workers besides the contractor. The state raised that small-job limit from $500 to $1,000, so older advice you find online may be out of date. Ask for the license number before you sign anything.
What causes concrete driveways to crack in Pleasant Hill?
Most cracking comes from ground moving under the slab and from control joints cut late or not at all. Control joints are shallow grooves cut into the slab so it cracks in a straight line where we chose instead of across the middle. Concrete can still crack, but with the base dug out and packed for the clay we covered above, and joints cut on time, cracks tend to stay in the joints.
Does being in a flood zone change a concrete project in Pleasant Hill?
It can, because the city says improvements in its floodplain area may require a Floodplain Development Permit. The city counts about 700 homes inside flood zones FEMA has marked as Special Flood Hazard Areas. If yours is one of them, we raise that question early and pay extra attention to where water goes once the slab is down.
How much does a new concrete driveway cost in Pleasant Hill?
Your price comes from the estimate I write after seeing the job, because the biggest swings here are tear-out, base work and whether the job touches the street. If you need to trim the budget, cut the finish, not the base. A broom finish, a light brushed texture that gives shoes and tires grip, costs less than stamped or colored work, while the base is hidden on day one and decides whether the slab stays put.
