Concord driveways and patios, as we find them
Concord is a big, settled city, and most of our calls there are about the concrete around a house that's been lived in a long time. We see two-car driveways with a crack running down the middle, backyard patios that have dropped away from the back door and front walks lifted where the ground moved under them. It's much the same in the neighborhoods running toward Clayton and Walnut Creek, because the houses look alike and so does the ground under them.
Lots here range from flat streets to yards that climb toward the hills. How your lot sits decides how much digging and grading comes before the pour, so I look at the ground and the grade before we ever talk about the finish.
Concrete work we do on Concord properties
Concrete driveway building
When a Concord driveway has sunk, cracked across the middle or holds water at the garage, we tear it out, dig down to firm ground and pour new.
Concrete patio construction
Backyard patios here often slope the wrong way or have cracked into pieces. We build new ones on a packed base, pitched so water runs to the yard.
Stamped concrete services
Stamped concrete gives a patio the look of stone or brick in one pour, a good fit when you want the yard to match an older house.
Concrete sidewalk building
Front walks that have heaved or split trip people on the way to your door, so we pour new ones set to the grade of the yard.
Garage floor concrete
A garage floor that's cracked, stained or sloping the wrong way can be broken out and repoured, with the slope set so water runs out the door.
Decorative concrete
Color, exposed aggregate and saw-cut borders dress up an entry or a patio, and they suit owners updating an older Concord house without changing its layout.
Concrete retaining walls
On sloped lots, a retaining wall holds the hill back so you get a flat yard or patio, with drainage behind it so water doesn't push it over.
Concrete floor installation
For a shop, a storage building or a room addition, we pour interior floors flat and level over a packed base, ready for whatever goes on top.
Concrete pool decks
Pool decks around backyard pools here need a surface that drains away from the water and isn't slick underfoot, so we slope them and give them grip.
Concrete steps construction
Front steps that have pulled away from the porch or gone uneven cause falls, so we pour new ones with every step the same height.
Slab foundation building
For a garage, a backyard unit or an addition, we pour the slab foundation on dug-out, packed ground so the building has something solid to sit on.
Foundation installation
New foundations under additions and outbuildings start with layout and footings set to plan, because a wall that's off at the bottom stays off all the way up.
Concrete parking lot building
For small businesses in Concord, we pour parking areas graded so water drains off and thick enough for customer cars and delivery trucks.
Concrete footings
Decks, patio covers and garden walls sit on footings, concrete poured into holes or trenches below them, and we dig them deep enough to stay put.
Foundation raising
When part of a house has settled and the floors slope or the doors stick, foundation raising lifts that section back toward level so things work again.
Concrete cutting
We saw-cut old slabs so they come out clean, and cut openings for drains, doors or a wider driveway without cracking the concrete left behind.

Working in Concord: permits, licenses and what sets the price
Permits in Concord go through the City of Concord's Permit Center, and the city's list for single-family and duplex homes is only a partial list. It names work like roofs and water heaters but doesn't settle flatwork, which is driveways, patios, walks and slabs. So before we pick a start date, I check with the Permit Center for your address, and if a permit's needed, we apply for it as your contractor or help you file it yourself, which is the part that can move the schedule. While you're comparing bids, ask each contractor for a state contractor license and a Concord business license.
Most Concord driveways meet a city street with a curb and a public sidewalk, and the concrete truck parks on that street, so I look at where it can set up and whether we can chute straight off the truck or need a pump to reach a backyard. Access, the size of the job, how much old concrete comes out and how much dirt we dig out and replace with packed base set most of the price. The schedule turns on the permit check, the base work and the wait before you can use the new slab. I put all of it in the written estimate after I measure, and it's the same work we do from Antioch out to Oakley.
Concord slabs that sink, crack and hold water
Most of the sinking we see on Concord driveways and patios goes back to the subgrade, the dirt and rock the slab sits on, because it was raked level instead of dug out and packed, and the dirt settled and took the concrete down with it. On a new job, the base is the part nobody sees on day one and the first thing people want to cut from the budget. I won't cut it, because a nice finish on soft ground cracks and drops just the same. We dig to firm ground, bring in base rock and compact it before a single form goes up.
On sloped lots and older patios, the other common problem is water, either a slab that falls toward the house or a low spot where it pools against the foundation. Before we set forms, I check where the water runs now and set the slope so it heads to the yard or the street.
How a concrete job in Concord runs, start to finish
Here's what happens from your first call or message to the day I walk the finished slab with you, and who you'll deal with along the way.
Call or send us a message
Call (925) 503-1201 or use the form, and we'll get back to you to set a time for me to come out. It helps if you can be there to show me what's bothering you.
I come out and measure
I come out myself to look at the slab, the ground around it and how we'll get concrete to it, then send you a written estimate. You'll know the price and what it covers before you decide anything.
We handle permits and pour
Once you say go, we sort out anything the city or county needs, set forms, and my crew and I pour and finish. Then comes curing, the wait while the concrete hardens, and I'll tell you when it's ready to walk on and when it's ready to drive on, which takes longer.
We walk the job together
Before we leave, I walk the finished job with you so you can see the joints, the finish and where the water runs. We clean up and haul off the old concrete.
Questions about hiring a concrete contractor in Concord
Call (925) 503-1201Yes, the city says a project that moves soil or does work in the public right-of-way, the strip along the street, needs its own grading or encroachment permit from the Engineering Division, apart from any building permit. That can come up when a new driveway meets the street or a yard gets regraded, so I check for it early, while we plan the job.
Yes. The city requires a business license to do business in Concord, including for state-licensed contractors, and that holds even when the contractor's office is outside the city. We're based in Antioch, so the rule applies to us on every Concord job.
The Contractors State License Board requires a license when the project needs a building permit, uses any additional workers, or when the labor and materials on one or more contracts total $1,000 or more. That's why it's worth asking anyone pouring your driveway or patio to show you their state license before you sign. We're licensed and fully insured.
Your driveway's price comes from what I measure on site, so I send a written number after the visit instead of quoting over the phone. Beyond the size and the tear-out, the finish and the thickness move it most. A plain broom finish, the light brushed texture that keeps tires and shoes from slipping, costs the least, while stamping, color or a thicker slab for an RV costs more.
Type your address into EQ Zapp, the California Geological Survey's statewide map tool, and it shows whether the property lies in any of its mapped earthquake hazard zones. If you're planning a slab foundation, footings or a retaining wall, look it up before I come out and bring what it shows to the visit.
Concrete shrinks as it hardens, so every slab cracks somewhere, and the honest goal is to tell it where. We cut control joints, the straight grooves across the slab, early enough that the cracks form inside them where you'll hardly notice, and we set rebar, steel bars inside the slab that hold the pieces together if a crack opens. The packed base keeps the slab from dropping at those cracks.
