What's involved in building a new sidewalk in Concord?
Concrete sidewalk building in Concord means breaking out the old walk, digging down to firm ground, watering and packing a new base, then forming, pouring and finishing fresh concrete. You end up with a walk that sits level and sheds water instead of tripping people.
Most people call me because a square has lifted, a crack has opened across the walk, or a notice has shown up from the city. The price moves with how much walk comes out, how much digging the base needs, any tree roots in the way and the finish you pick. The schedule mostly turns on the city's permit and inspection, because a walk out front usually sits on city land, and we handle that permit paperwork when one is needed. We're based in Concord and work in the cities around it, and the written estimate I put together on site gives you your own number.
How do you know your sidewalk needs replacing?
A square sticking up
When one panel sits higher than the next, it's usually roots or a base that moved underneath. The edge tends to keep rising, and that lip is right where someone catches a toe.
Cracks across the squares
Cracks that run through the middle of a panel, instead of along the cut lines, mean the concrete broke where nobody planned it. Water gets in, pieces loosen, and a crack you could live with becomes a square you have to replace.
Puddles after it rains
Water sitting on the walk means a panel has sunk or was never pitched to drain. Each soaking softens the base a little more, so the low spot usually gets lower.
How we build a concrete sidewalk, from tear-out to finish
Once the city side is settled, we cut the edges so the break stops where it should, then break out the old concrete and haul it away. We dig out the subgrade, which is the dirt the slab sits on, until we reach firm ground, cut out any soft or spongy spots, then water and pack the base so the new walk doesn't settle the way the old one did. We set forms with a slight fall away from your house so rain runs toward the street, and we pour while the day's still cool, because a pour in midday heat can leave a weak, dusty top. Then we give it a broom finish, the light texture that keeps shoes from slipping when it's wet, and cut control joints on time, the grooves that give concrete a planned place to crack. If the budget is tight, I'd rather you skip a fancy finish than skimp on the base, because nobody sees the base on day one and everybody sees it once the walk starts to sink.
A sidewalk job often turns up other work nearby. If the slab in your garage has the same cracks, we can pour new garage floor concrete too, and if you'd like color or a pattern on a patio or entry, that's our decorative concrete work.
Replace only the damaged squares
This suits a walk with one or two lifted or broken panels while the rest is still flat and sound. It's the smaller job, though fresh concrete won't match the color of the old squares at first.
Replace the whole run
This suits a walk with cracks all along it, low spots that hold water or panels at several heights. One pour gets you a single even line and a base built the same way from end to end.

What happens after you call about a sidewalk in Concord?
Here's how a sidewalk job runs from your first call to the final walk-through, and what you'll have in hand before you decide anything.
Call or send the form
Call (925) 536-0945 or send the form with your address, the rough length of the walk and any notice from the city. The address tells me which office covers you before I come out.
Walk the site with me
I come out, look at the walk with you, explain your choices, including the city's own repair program, and put the estimate in writing. You'll see where the money goes, from tear-out and base work to the finish, with the city's permit fee kept separate.
We line up the permit
We sort out the permit with the city or county that covers your address. Concord's permit conditions allow work from 8:00 a.m. to 5:00 p.m., Monday through Friday, with weekends only by the City Engineer's approval, so we plan your job on weekdays.
Build it and walk it together
I'm on site with our form setters and finishers, and your neighbors' driveways stay open the whole time because the city's conditions require it. When it's done, we walk the finished sidewalk with you.
Why Concord homeowners call King Concord Concrete Works for sidewalks
The owner writes your estimate
I come out myself to look at the walk and write the estimate, and I'm on site during the work with a small crew of form setters and finishers. The person who priced your base is the one watching it get packed.
In business since 2020
We've been in business since 2020, and before that I learned the trade on small jobs of my own and on other people's crews. I explain each choice before you sign, so you know what you're paying for.
Licensed and insured for concrete
We're licensed and insured. In California, sidewalks and other flat concrete fall under the state's C-8 concrete contractor class, so that's the license class to ask any bidder about.
Concord's permit sorted before we form
We check with the city or county that covers your address and handle the permit paperwork when one is needed, which for a Concord front walk usually means the encroachment permit. You don't have to learn the city's process to get a walk built.
When you're ready, contact us or call (925) 536-0945, and I'll set up a time to look at your walk.
Sidewalk building and the city's side of the job in Concord
A sidewalk out front usually sits in the right-of-way, the strip of public land along the street, and Concord requires an Encroachment Permit for any work inside it. The City of Concord is the one to tell you whether your walk falls in that strip, because the permit covers only that area. Applications go through the city's online permit portal, and the city reviews each one and sets the conditions and fees for the job. We handle that application for you, and we don't set a form until we know what the city wants.
On older streets around Concord, what we see most is panels pushed up by street-tree roots and squares that sank where the base was never packed, and we see the same thing on jobs in Pleasant Hill and Walnut Creek. That's why I look at the whole run before pricing one square, since a lifted panel often has a neighbor that's next.
Questions about concrete sidewalks in Concord
Who is responsible for the sidewalk in front of my house in Concord?
In Concord, the property owner is responsible for maintaining and repairing the sidewalk, curb and gutter in front of or beside their home or business. The city bases that on state law and its own city code, which is why the bill for a cracked front walk lands with you. If you've had a notice from the city, bring it to the estimate.
Do I need a city permit to replace my sidewalk in Concord, and what does it cost?
Yes, work in the city's right-of-way needs an Encroachment Permit, and the city's FAQ lists the fee for sidewalk removal and replacement at $1,343.12, which includes a $500 refundable deposit. That fee comes on top of the construction price when you hire your own contractor, so budget for both. We handle the permit paperwork as part of the job.
What happens if sidewalk work in Concord skips the city inspection?
You could have to tear it out and rebuild it at your own cost. Under the city's permit conditions, all the work is subject to inspection and approval by the City Engineer, and work done without inspection may have to be removed and rebuilt at the permit holder's expense. We plan the inspection into the job from the start.
How much does a concrete sidewalk cost per square foot in the Bay Area?
Installed concrete sidewalk or 4-inch slab work in the San Francisco Bay Area usually costs about $5 to $18 per square foot. That's the going rate in the area, not a quote from us, and where your job lands depends on how much old concrete comes out, how much base work it needs, roots, access and the finish. The city permit fee is separate, and your written estimate gives you your own number.
What is the best way to choose between Concord's Sidewalk Repair Program and my own contractor?
Compare both on price and on how much of the process you want to handle. The city's Sidewalk Repair Program is meant to lower the cost of repairing and replacing sidewalks compared with hiring an independent contractor, with economy-of-scale pricing, waived permit fees, and no contractor to pick or inspections to schedule. Hiring your own contractor means paying the permit fee, but you choose who builds it and when, and I'll lay both routes out at the estimate.
What causes a sidewalk to crack and lift near a tree?
Roots growing under the walk are the usual cause, because rigid concrete can't bend as they thicken. A university extension guide from Iowa says pavers, bricks, rubber pavers or flexible asphalt handle root growth better than concrete near trees, and it warns that cutting major roots can remove a large part of the tree's root system and lead to branch dieback or a dead tree. If there's a tree near your walk, point it out at the estimate so we can talk it through before anything gets cut.
Other concrete work to pair with a new sidewalk
Garage floor concrete
If your garage slab is cracked or sinking like the walk, pricing both together can make sense while the crew is already out here.
Decorative concrete
For a patio or entry where you'd like color, texture or a pattern worked into the concrete instead of a plain gray broom finish.
