Concrete contractor services in Concord, CA
King Concord Concrete Works is a concrete contractor in Concord, CA, with 16 services that run from a new patio to lifting a house that has settled. Most calls start with something you can see, like a cracked driveway, a sinking slab or water pooling by the house. The price mostly comes down to size, how much old concrete we break out and haul off, how much digging and packing the ground needs, and the finish you choose. The schedule turns on any permit and on curing, the days new concrete needs to harden before you use it. I'll put your own figure in writing when I come out.
Concrete driveway building
A new driveway starts below the surface, so we dig out soft soil, pack a gravel base and pour a slab thick enough for your cars.

Concrete patio construction
Want a flat, solid spot for a table and grill out back? We build concrete patios sloped gently so water runs toward the yard, not the house.

Stamped concrete services
We press patterns and color into fresh concrete so a patio, walk or pool deck looks like stone, brick or slate, then seal it to hold the color.

Concrete sidewalk building
We pour front walks, side paths and garden walkways with a broom finish, a brushed texture that gives shoes grip when the concrete's wet.

Garage floor concrete
Need a garage floor that's flat, easy to sweep and tough enough for cars and a workbench? We pour new garage slabs and replace cracked, oil-soaked ones.

Decorative concrete
Decorative concrete covers color, exposed stone, scored patterns and special finishes, for homeowners who want a patio or entry that looks like more than plain gray.

Concrete retaining walls
We build poured concrete retaining walls to hold back soil on sloped yards, with steel inside and drainage behind so water pressure doesn't tip them.

Concrete floor installation
What's a concrete floor for? Shops, sheds, basements and additions, anywhere you want a flat, hard surface finished smooth so you can seal it or cover it later.

Concrete pool decks
We pour decks around new and existing pools, sloped so splash water drains away from the pool edge and the house, with a textured top for bare feet.

Concrete steps construction
Front and back steps need every step the same height so nobody trips, and we form and pour concrete steps to fit your doorway and walk.

Slab foundation building
For a new garage, addition or backyard cottage, we build slab foundations, one pour that serves as both the floor and the base the walls stand on.

Foundation installation
Foundation installation covers the footings, walls and anchors a new structure rests on, and we build them to your approved plans before framing starts.

Concrete parking lot building
Small property owners call us for concrete parking areas and lots, built thicker than a home driveway and sloped so water reaches the drains instead of puddling.

Concrete footings
Footings are the buried concrete pads and strips that carry a deck, wall, porch or post down to firm soil, and we dig and pour them to size.

Foundation raising
Doors sticking, floors sloping, cracks running up the drywall? We lift settled foundations back toward level and support them so the house has solid footing again.

Concrete cutting
When part of a slab has to come out, or a drain or doorway needs an opening, we saw-cut it cleanly instead of jackhammering.

Reasons homeowners hire us for concrete work
Most of our calls come from homeowners in Concord and the cities around it, plus some small property owners. Here's how we run a job, and why it matters for yours.
Options explained before you commit
On site I lay out your choices in plain words, like a broom finish versus stamped, or fixing one section versus replacing the whole slab, so you pick the right work before signing anything.
The owner at your pour
I'm the one who looks at your job, and I'm at the pour with our small crew of form setters and finishers, so what you agreed to is what gets poured.
Straight answers on how concrete ages
Concrete ages like anything else. Before you sign, I tell you which hairline cracks are normal and when a fresh coat of sealer usually makes sense, so you know what to expect after we leave.
Permits worked out for your address
We find out whether the city or the county covers your address, check what your job calls for and handle the permit paperwork when one's needed. Call (925) 536-0945 to talk it through.

I visit and write it up
I come out and look at the site with you, including the ground the slab will sit on and where water runs across your yard. I explain the choices and what each one means for price and upkeep, then put a free estimate in writing, with no obligation.
Permits, then the pour
Once you're set, we sort out the city or county side and handle the permit paperwork if your job needs it. Then our crew of form setters and finishers digs out and packs the base, sets the forms and pours, and I'm on site working with them.
Walk the finished job
When the work's done, we clean up and I walk the finished job with you. I'll show you where the joints are, tell you when you can walk on it and when you can drive on it, and go over what it needs to stay in good shape.

Concord, the city we call home
Concord is where we're based, and most of our calls come from homeowners here. People know the city by its gathering places, like Todos Santos Plaza downtown, where families come for outdoor concerts and lunchtime strolls, Newhall Community Park with its creek-side picnic area under big oaks, and Dave Brubeck Park on the north side. The streets around them are full of houses whose driveways, patios and front walks range from fairly new to decades old, and we see plenty of settled slabs and cracked walks.
Concrete work on a Concord house runs through the city's Permit Center, which can help you find out which permits a project needs and estimate the fees before you ask for bids. When a job moves soil or reaches into the public strip along the street, the city also asks for separate grading and encroachment permits from its Engineering Division, so a new driveway that meets the street can carry an extra step. We check all of that for your address before we pour, the same as we do in the cities around Concord.

Questions about concrete work in Concord, CA
Why do concrete driveway quotes in Concord vary so much?
Quotes usually differ because of what's under the slab, not what's on top, since one contractor digs out and packs the base and another just rakes the dirt level. When you compare bids, ask each contractor how deep they'll dig, how thick the slab will be and where the joints will go.
Where can I save money on a concrete driveway or patio?
Save on the finish, not the base. A plain broom finish costs less than stamped or colored concrete, but the base is the part you can't fix later without tearing the slab out. It's hidden the day we pour, which makes it the first thing people want to cut and the last place I'd cut it.
How long will I be without my driveway after new concrete is poured?
You can usually walk on new concrete well before you can drive on it, because it keeps curing and gaining strength for a while after it looks dry. I'll give you the dates for your slab before we pour. If your job needs a permit, that part often takes longer than the pour itself.
Does a concrete contractor in Concord need a license?
Yes, the state licensing board requires a contractor's license when a job needs a building permit, uses any extra workers or totals $1,000 or more in labor and materials. The City of Concord also requires a business license to work in the city, including for licensed contractors whose office is elsewhere. We're licensed and insured.
Do I need a permit for a concrete driveway or patio in Concord?
It depends on the job, so we check with the city or county office that covers your address before any work starts. The city's permit list for houses names things like roofs, water heaters and windows, and it doesn't settle every concrete job. When a permit is needed, we handle the paperwork.
Do you guarantee your concrete work?
Yes. Satisfaction guaranteed on every job. That can't mean a slab that never shows a crack, because concrete shrinks as it cures, so I'm clear on site about what's normal and what isn't.
Will my new concrete driveway crack like the old one?
Some hairline cracking is normal as concrete shrinks, but a well-packed base and control joints cut on time usually keep those cracks thin and inside the lines we planned. Control joints are grooves we cut so the slab cracks along them instead of across the middle. Old slabs often break up because the base was raked level instead of dug out and packed, so it settled with the dirt.
How do I check if my Concord home is in an earthquake hazard zone?
Type your address into EQ Zapp, a map tool from the California Geological Survey that shows whether a property sits in any of its mapped earthquake hazard zones. It's worth a look before foundation, footing or retaining wall work, and you're welcome to bring what it shows to the estimate so we can talk it through.
