What goes into building a new concrete sidewalk in Antioch?
Concrete sidewalk building in Antioch, CA, is forming and pouring a new walk on ground that's been dug out, watered and packed, so your front walk, side path or street sidewalk sits flat and sheds water away from the house.
Most calls come when an old walk has heaved, sunk or cracked into pieces, or when a dirt path has worn in where a walk should be. The price moves with the size, whether there's old concrete to break out and haul off, how much soft ground has to come out, how easy it is to get concrete to the spot and the finish you pick. The schedule turns on the ground, because wet soil has to dry or be dug out first, and on any permit, because if your walk runs along the street we check with the city or county first and handle what they ask for. If the walk meets a new concrete driveway, we lay them out together so the edges line up. I walk and measure the job and send a written price, so you're deciding on your own number and not a guess.
How do you know your sidewalk needs replacing?
Slabs lifted at the edges
You see one slab sitting higher than the next, with a lip that catches a toe. That usually means roots or soft ground moved it, and the longer it sits, the bigger the lip gets and the more the edges chip off.
Puddles after rain or sprinklers
Water sits on the walk or runs back toward the house instead of off to the side. It usually means the walk sank or was poured without enough fall, and that water soaks the ground underneath, which softens it and lets the walk sink more.
Cracks running across slabs
Cracks wander through the middle of slabs instead of following the grooves, and some pieces rock when you step on them. That usually points to a base that settled or joints cut late, and once pieces start rocking they break up quickly.
How we build a concrete sidewalk
If your walk runs along the street, we check with the city or county before anything else, then break out any old concrete and haul it away. Next we dig down to firm soil and deal with the soft spots, either digging them out or letting the ground dry, because a walk poured over spongy dirt sinks right along with it. We water and pack the subgrade, the ground the slab sits on, then set the forms and check them for size and slope before the truck comes, since fixing a bad grade after the pour usually means tearing it out. We pour in the cooler part of the day when we can so the top doesn't dry too fast and turn dusty, cut control joints, the grooves that give concrete a place to crack, and finish it with a broom finish, a light texture that keeps the walk from getting slick when it's wet. If you need to trim the budget, cut the fancy finish before you cut the base work, because nobody sees the base on day one and it's the part that decides how the walk holds up.
A walk is often one piece of a bigger job. If it runs up to the garage, it makes sense to look at the garage floor concrete at the same time, and if you want color or a pattern on the path to your door, that's our decorative concrete work, poured on the same packed base.
Plain broom-finished walk
This suits most front walks, side paths and street sidewalks, because the texture grips underfoot and it costs the least. It's also the easiest to blend with a neighbor's section or the walk next to yours.
Colored or patterned walk
This suits an entry where looks matter, since color or a pattern dresses up the path to your front door. It costs more and some finishes are slicker than broom, so we talk through where people walk in the rain.
Tear-out and replace
This suits an old walk that's heaved, sunk or broken past patching, because new concrete over a failed base just fails again. We break it out, haul it off and fix the ground before anything new goes in.

Sidewalks, street permits and soft ground in Antioch
A walk along the street sits in the public right-of-way, and the city's Engineering Division issues the encroachment permit for sidewalk work there. Walks on your own lot are a separate question, so before we start we check with the city or county office that handles your address, and if a permit is needed, we apply for it as your contractor. The city requires every contractor to hold a state license and a City of Antioch business license. On a street job it also asks for a traffic control plan with the permit and any time the work affects cars, people on foot or bikes, and it has applicants call USA North 811 to mark buried lines 2 to 14 working days before any digging.
Plenty of older walks around here were poured on dirt that was raked level instead of packed, and they've settled, tipped toward the house or lifted where roots push up. We see the same on jobs in Pittsburg and Oakley, and since we're based in Antioch and work the cities around it, we plan for damp yards with either drying time or a dig-out.
Questions about concrete sidewalks in Antioch
Call (925) 503-1201A standard 4-inch concrete slab with a basic broom finish usually costs about $13 to $18 per square foot in the Bay Area, and that's the general market range, not our price. Tearing out an old walk, digging out soft ground, a decorative finish or a street permit can push a job above a plain new slab. I measure your walk on site and send a written price for it.
A walk along the street needs the city's encroachment permit, while for a walk on your own lot the Building Division says most residential flatwork doesn't need a permit. Most isn't all, so we check with the office that handles your address before we start, and you'll know where you stand before any digging.
Yes, if you own the property next to the walk, because Antioch issues encroachment permits only to adjacent owners or to contractors licensed by the State. If you'd rather file it yourself, we help you through it, or we can file it for you.
A state contractor license from the Contractors State License Board, and its C-8 Concrete class covers forming, pouring and finishing flat concrete. The state requires a license when a job needs a building permit, uses added workers or comes to $1,000 or more in labor and materials. C-8 contractors can't use the no-employee exemption from workers' comp, so a licensed concrete contractor carries that coverage even when working alone.
Pour it on firm, packed ground, because a walk sinks along with whatever is under it. Caltrans guidance for its own sidewalks has soft or spongy ground removed unless it's left to dry first, has the ground watered and compacted, and has it wet again right before the concrete goes in. On a damp site that means planning for a wait or a dig-out, and we'll tell you which one your yard needs.
It can, because all concrete cracks, and anyone who tells you otherwise isn't being straight with you. What we can do is give it joints so the cracks follow the grooves, and build a packed base so the slabs don't settle and break into pieces. Old walks that cracked everywhere were usually poured on loose dirt with joints cut late or not at all.

Garage floor concrete
If your walk ends at the garage, a cracked or sunken garage floor is often the next thing worth fixing, and doing both together saves a second setup.

When a plain gray walk won't match your entry, color, patterns or exposed stone can make the path to your front door look finished.
