Norwalk homes and the concrete around them
Norwalk is mostly streets of single-family houses, many with a driveway running down the side to a garage and a patio off the back door, plus apartments and shops along the busier roads. A lot of the concrete we get called about here was poured long before the current owner moved in, so we see the same things over and over: a driveway that's dropped at the garage, a patio that tips toward the house, a front walk lifted by a tree root. It's much the same story next door in Downey.
That means nearly every job here starts with breaking out and hauling the old slab, and what we find under it decides how much base work the new one needs.
Concrete services for Norwalk homes and businesses
Concrete driveway building
When an older Norwalk driveway has cracked, sunk at the garage or started holding water, we tear it out, rebuild the base and pour a new one.
Concrete patio construction
For backyard slabs that tilt toward the house or have heaved, we pour a new patio pitched to send rain out to the yard instead.
Stamped concrete services
Stamped concrete gives a Norwalk patio or front walk the look of stone or brick, poured as one slab so there are no pavers to shift or weed.
Concrete sidewalk building
Front walks and side paths lifted by roots or broken into trip edges get dug out and repoured with a broom finish, a light texture for grip.
Garage floor concrete
Older garage floors here are often cracked, stained or sloped wrong at the door, and a new slab gives you a flat floor to park and work on.
Decorative concrete
Colored concrete, exposed aggregate and scored patterns let a plain Norwalk yard get a finished look without the upkeep of wood or loose pavers.
Concrete retaining walls
Where a yard steps down to a neighbor or a planter is pushing over, a concrete retaining wall holds the soil back and keeps water draining past it.
Concrete floor installation
Interior slabs for converted garages, back rooms and shops get a packed base and a level pour, so the flooring goes down flat later.
Concrete pool decks
Decks around older backyard pools here usually crack and lift at the edge, and we repour them with a textured surface meant for wet, bare feet.
Concrete steps construction
Front porch steps that have cracked, settled or pulled away from the house get formed and poured new, with even rises so nobody catches a toe.
Slab foundation building
For backyard units, additions and new garages going up on Norwalk lots, we pour the slab on a packed base with rebar, the steel that holds it together.
Foundation installation
When a room addition or detached structure needs a perimeter foundation instead of a slab, we dig, form and pour it to the plans you're building from.
Concrete parking lot building
Small business owners and landlords along Norwalk's commercial streets call us for lots and aprons that hold up under daily traffic and drain where they should.
Concrete footings
Patio covers, block walls, carports and posts all need footings, the concrete pads under the load, and we dig and pour them to the plan's depth.
Foundation raising
When part of an older house or garage has settled and doors stick or floors slope, we look at why it sank before we lift anything.
Concrete cutting
We saw-cut old slabs for new drain lines, wider driveways or doorways, and cut control joints, the grooves that tell a slab where to crack.

Working in Norwalk: permits, licenses and what sets the price
If your job needs a permit, we pull it, set up the inspections and deal with whichever office covers your address, city or county, so you aren't the one chasing paperwork. When there is a permit, it has to clear before we pour, so it usually sets the start date more than the concrete does, and after the pour you wait out the cure, the days the concrete needs to harden before it takes weight. California requires a state license for most concrete work, and we're fully licensed and insured, so ask any contractor you're comparing, us included, for their license details before you sign. Price mostly follows the size of the job, how much old concrete comes out and how much base work the ground needs, and your written estimate puts the figure for yours on paper.
Most of our Norwalk jobs are on residential streets with cars along the curb and the garage set back on the lot, so before pour day we work out where the truck sets up and how the concrete reaches the backyard, by chute, wheelbarrow or pump. We do the same flatwork in Walnut Park and around our home base in South Gate, so a tight side yard doesn't surprise us.
Older Norwalk slabs and what usually ruins them
Most cracked and sunken slabs we break out here were poured on dirt that was raked level and never packed, so the ground settled and took the concrete with it. We dig down to the subgrade, the firm ground the slab actually sits on, then bring in base rock and pack it in layers, with about four inches of concrete for a patio or walk and more where cars park. That base disappears from view on day one, which is why it's the first thing people want to trim from a budget, and I'd rather you pick a plainer finish than a thinner base.
The other thing we see is water. A slab that falls toward the house sends the rain straight to your foundation and garage door, so before we form anything I check where your water runs now and pitch the new concrete away from the house.
How a concrete job runs when you call us from Norwalk
Here's what happens from your first call to the day we pack up, and who you'll be dealing with along the way.
Call or send the form
Call (213) 329-1420 or use the form and tell us what you have in mind. We set a time for me to come out and see the job.
I come out and measure
I come out myself to measure and look at the ground, where your water runs and anything in the way, like roots, lines or a narrow side yard. You get a written estimate afterward, so the price is on paper before you decide anything.
We prep, form and pour
If the job needs a permit, we pull it and set up the inspections before we dig. Our crew handles the tear-out, base, forms and finishing, and I'm usually there on pour day.
We walk it together
Before we pack up, I walk the finished job with you to look over the edges, the joints and how it drains. We tell you when you can walk on it and when you can park on it, since that depends on the cure.
Concrete contractor questions from Norwalk
Call (213) 329-1420Does a concrete contractor in Norwalk need a California state license?
Yes, for nearly any real concrete job. California requires a license from the Contractors State License Board for anyone who contracts for work that needs a building permit, uses employees or workers, or comes to $1,000 or more in combined labor and materials. A driveway or patio poured by a crew clears that bar easily, so get the license details before you sign anything.
Which small concrete jobs can be done without a contractor license in California?
A job can skip the license only when it meets every condition of the state's minor work exemption. Labor, materials and all other costs on the job have to total less than $1,000, the work can't need a building permit, nobody can be hired to help, and the person can't advertise as a licensed contractor. That limit went from $500 to $1,000 at the start of 2025, so older advice you find online may still say $500.
Can I pour my own concrete patio in Norwalk without a license?
You may not need a license, because the state board says owner-builders may be exempt. That covers owners who build or improve existing structures on their own property and do the work themselves or with their own employees paid in wages. It's about the license only, and it doesn't settle whether your project needs a permit.
How do I check if my Norwalk address is in an earthquake hazard zone?
Type your address into the state's EQ Zapp map, which shows whether your property sits in any of the state's mapped earthquake hazard zones. Those zones cover ground failure like soil liquefaction, where soaked ground gives way in a quake, and the tool also tells you if the state hasn't evaluated your area yet. If you're planning a slab foundation or footings, show me what it says when I come out.
How much does a new concrete driveway cost in Norwalk?
Your price comes from the size of the driveway, how much old concrete has to be broken out and hauled, how much base the ground under it needs, and the finish you pick. A broom finish costs less than stamped or colored concrete, and a driveway that has to carry a truck or RV needs more thickness and steel. I measure it on site and give you the figure in writing.
What causes a new concrete patio to crack, and how do you keep it from happening?
Most cracks in a new slab come from concrete shrinking as it dries, ground settling under it, and joints cut too late or skipped. Besides the base work, we cut control joints while the concrete is still young so any cracks run where we planned them, and we keep the pour out of the hottest part of the day so the top doesn't dry weak and dusty. Keeping furniture and cars off it until the cure is done does the rest.
