What goes into a new concrete floor in Concord?
Concrete floor installation in Concord means we form, pour and finish a flat slab for a room, an addition, a shop or a shed, so you end up with a solid, level floor that fits how you'll use the space.
Most people who call about a floor either have an old slab that's cracked, sunk or chipping, or bare ground in a back room or outbuilding that never got a real floor. The price turns on the size of the floor, whether an old slab has to be broken out and hauled away, how easily we can get concrete into the space and how much digging the base needs. The schedule turns mostly on whether your address needs a permit and how soon we can get in. I settle the license and permit questions when I first come out, not halfway through the job, and the written estimate gives you your own figure.
How do you know your concrete floor needs replacing?
Cracks that keep widening
A hairline crack is normal for concrete, but cracks that open wider, shift height or run across the room usually mean the slab has lost support underneath. Waiting tends to turn one crack into several, and a raised edge into broken pieces you trip on.
One side sitting lower
If a ball rolls to one corner or a door starts rubbing, the floor has likely settled because the base under it wasn't dug out and packed. The longer it sinks, the more of it has to come out when you finally deal with it.
A dusty, chipping surface
A top that sheds powder or chips under a chair leg often comes from a pour done in the midday heat that dried too fast. It keeps wearing, and anything you lay or paint over it tends to let go.
How our concrete floor installation works
I start by looking at where the floor goes, what's there now and how you'll use the room, and I walk you through the plan before anyone picks up a tool. If an old slab is there, our crew breaks it out and hauls it off, then we dig out and pack the base, the ground the slab sits on, because a floor poured on loose, raked dirt settles right along with it. We set the forms, pour when it's cooler so the top doesn't come out weak and dusty, finish the surface and cut control joints, shallow grooves that give the slab a straight line to crack along instead of a random one, then clean up. If the budget gets tight, the base is the last place I'd cut, because you can't see it on day one and you'll notice it every day after if it was skimped.
A new floor often brings other work with it. If the room sits above the yard, the door usually needs concrete steps to reach it, and if it opens toward the water, we can pour concrete pool decks while we're set up so the levels line up.
Replacing an old slab
This suits a floor that's cracked, sunk or chipping past patching, because tearing it out lets us fix the base that caused the trouble instead of covering it up. It's more work than leaving the old slab in place, and it's usually the version that holds up.
A new floor on bare ground
This fits a shed, shop or back room that's had dirt or gravel underfoot, since we start with a clean dig and build the base up from there. Think now about how the room will be used, because that shapes the plan.
A floor for an addition
When a room is being added on, the floor gets poured to match the rest of the build and the floors you already have. We work out the levels with you before the pour so the doorway between old and new doesn't end in a step nobody planned.

What happens when you call about a concrete floor in Concord?
From your first call to the final walk-through, here's who does what and what you have in hand at each step.
Call or send the form
You call (925) 536-0945 or send the form, and we set a time for me to come out. Mornings, evenings and weekends are all on the table.
I walk the space with you
I look at where the floor goes, what's there now and how you'll use the room, then explain the choices and what each one changes in the price. You get a written estimate that spells out what's included, so you can compare it line by line.
We sort out the permits
Once you're set, we check with the city or county that covers your address and handle the paperwork if a permit is needed. In Concord, the city's Permit Center is open weekdays from 8 a.m. to noon and 1 to 4 p.m., so we plan around those hours when something has to be settled in person.
We pour and walk it
I'm on site with a small crew of form setters and finishers for the work itself. When it's done, we walk the finished floor with you and go over what to expect from it.
Why Concord homeowners call King Concord Concrete Works for floors
The owner writes your estimate
I come out myself to look at the space and write the estimate, and I'm on site during the work with our crew. The person who explained the plan to you is the one watching it get poured.
Six years, explained plainly
We've been in business since 2020, and we're best known for laying out the options plainly before anyone signs. You'll know what you're paying for and how the floor should age, cracks and upkeep included.
Licensed and insured, settled up front
We're licensed and insured, and I go over the license and permit questions on the first visit. Getting those answered before the pour keeps a job from stalling halfway through.
Your city or county checked first
Most of our calls come from Concord and the cities around it, and for each job we check with the city or county that covers your address. That way the permit answer is part of your estimate, not a surprise after the forms are set.
A floor that doesn't surprise you later starts with a look at the space, so call (925) 536-0945 or ask for an estimate.
Concrete floors, steps and pool decks in Concord
Before we pour in Concord, we look at whether the job moves soil or reaches into the public right-of-way, the strip along the street the city controls, because either one calls for separate grading and encroachment permits you apply for through the city's Engineering Division. Whether the floor slab itself needs a building permit is a question for the city or county that covers your address, so I don't guess at it. We check it for your job and handle the paperwork when a permit is needed.
Much of what we see around Concord is older houses with back rooms, additions and sheds that never had a proper floor, or had one poured fast on raked dirt. We see the same on jobs in Walnut Creek and Pleasant Hill, and we handle them the same way, starting with the base.
Questions about concrete floors in Concord
How much does it cost to install a concrete floor in Concord, CA?
The cost of a concrete floor in Concord is set by how big it is, whether an old slab has to come out first, how hard the space is to reach with concrete and how much base work the ground needs. Permits for your address can add to it, and the next answer covers how to see those fees ahead of time. The written estimate after I see the space gives you the full figure.
How do I find out which permits my concrete floor project needs in Concord?
Concord's Project Pal tool gives you zoning information, tells you which permits your project requires and estimates the permit fees. That lets you see the permit side before you set a budget or a start date, and we check it for your address as part of the estimate.
When does a concrete floor job need a licensed contractor in California?
California requires a licensed contractor if the job needs a building permit, uses employee labor, or comes to $1,000 or more in labor and materials together. Any one of those is enough, and the state's Contractors State License Board is the office that licenses contractors, so ask about the license before you sign anything.
Where do I apply for a permit and follow inspections in Concord?
You can apply any time through Concord's Permit Portal, which is open around the clock. Once the job is moving, the same portal shows where your application and inspections stand and lets you search past permits, and in person the Permit Center is in Building D at 1950 Parkside Drive.
Who do I contact at the City of Concord with a permit question?
Email the city's permit staff at bldgpermits@cityofconcord.org or call 925-671-3107, and they aim to answer within 24 hours. If we're doing your floor, send the question our way first and we'll take it up with them.
What causes a new concrete floor to crack?
Most cracking comes from concrete shrinking a little as it hardens and from a base that settles, so a few fine cracks over the years are normal. The packed base and the cut joints described above keep cracks thin and in straight lines, and I'll tell you at the estimate what to expect and what upkeep looks like.
