Walnut Creek concrete work, from driveways to backyard patios
Walnut Creek is part of our regular run from Antioch, and most of the calls here are for flatwork, the driveways, patios, walks and steps that sit right on the ground. People usually call when a driveway has cracked through or lifted, a patio has settled and started holding water, or the front steps have begun to tip. Yards here tend to be well kept, so we're often pouring right beside planting beds, mature trees and a neighbor's fence, and I plan the dig and the truck route around them before we start.
It's the same flatwork we pour next door in Pleasant Hill and over in Concord. What changes from one house to the next is access, because a backyard patio behind a finished front yard means working out how the concrete gets back there, by pump or by wheelbarrow, before we ever dig.

Concrete services for Walnut Creek homes and businesses
Concrete driveway building
When an older driveway has cracked through, lifted at a tree or holds water by the garage, we tear it out, rebuild the base and pour it fresh.
Concrete patio construction
For backyards that step down from the house, we grade the patio so rain runs toward the yard, not back against your foundation or slider.
Stamped concrete services
Stamped concrete gives a front walk or patio the look of stone or brick, a good fit when you want it to suit an older home's character.
Concrete sidewalk building
We pour side-yard paths and walks across the yard, and if the sidewalk out front needs replacing, we check with the city before we break it out.
Garage floor concrete
When a garage floor has sunk, cracked or stained beyond saving, we break it out and pour a new slab that drains toward the door.
Decorative concrete
Colored or exposed-aggregate finishes suit homeowners here who want their concrete to sit well beside a landscaped yard instead of looking like plain gray slab.
Concrete retaining walls
On lots with a slope, a concrete retaining wall holds back the bank so you can level a patio or widen a driveway below it.
Concrete floor installation
We pour interior concrete floors for additions, workshops and small commercial spaces, with the base packed and the slab finished flat for what goes on it.
Concrete pool decks
Around a backyard pool, the deck has to shed splash water away from the pool and the house and stay comfortable under bare feet.
Concrete steps construction
Front steps that tip, crumble at the edges or have heights that don't match are common on older homes here, and we rebuild them solid and even.
Slab foundation building
For an addition, a detached garage or a backyard studio, we pour the slab foundation on a dug-out, packed base so the building sits level.
Foundation installation
When a new structure needs footings and foundation walls, especially on a sloped Walnut Creek lot, we lay it out and pour it to the plans.
Concrete parking lot building
Small business owners with a cracked or puddling lot can have it replaced in concrete, graded so rain drains off instead of sitting at the entrance.
Concrete footings
Decks, patio covers and garden walls need footings, the concrete underneath that carries the load, and we dig and pour them to the plans.
Foundation raising
If part of a slab or foundation has dropped and doors stick or floors slope, we look at why it moved before we talk about lifting it.
Concrete cutting
We saw-cut openings, trenches and clean edges in existing concrete, like cutting out a lifted section beside a tree instead of tearing out the whole driveway.

Working in Walnut Creek: permits and what moves the price
Permits here go through the city's Community Development Department, and inside city limits its rules are the ones your job follows. The city requires a building permit when you add a structure or physically change your property, and its permit FAQ lists private flatwork like a patio, a replaced driveway or a path as work that doesn't need one, but replacing the driveway approach, the apron where your driveway meets the street, or the sidewalk in front of your house takes an encroachment permit. Before we start, we check with the city for your address, and if a permit is needed we apply for it as your contractor or help you file it yourself, which puts that wait at the front of the schedule. We're licensed and fully insured.
What moves the price is mostly what you can't see in a photo: the size of the job, how much old concrete comes out, how much digging and grading the ground needs, whether a truck can reach the forms or we need a pump, and the finish you pick. What moves the schedule is any permit, the base work and curing, the stretch where new concrete sits and gains strength before you use it, so I put your price and timing in a written estimate after I've walked the site. We cover Walnut Creek on the same trips that take us out to Clayton, so getting out to see your job is easy to set up.

Why Walnut Creek driveways and patios need careful prep
Plenty of yards here have some fall to them, especially on streets that climb toward the hills, and on a slope the trouble is water. A patio poured to follow the ground as it is can send rain back toward the house or wash out the base at the low edge, so we set the grade first, decide where the water goes, and add a retaining wall where the yard needs one to hold a level slab. That grading is hidden once the concrete's down, which is exactly why we don't rush it.
Big trees are part of what people like about Walnut Creek, and their roots lift a lot of driveway panels and walks. The city protects any tree, dead or alive, measuring 9 inches or more at 54 inches above the ground, and only certain ones can come out with a Tree Removal Permit from the City Arborist, so we plan the new slab around the tree rather than through it.
How a concrete job runs when you call us in Walnut Creek
Here's how it goes from your first call to the day I walk the finished slab with you, so you know what's coming and when you need to be home.
Call or send the form
Tell us what you've got, whether it's a cracked driveway, a new patio or steps that tip, and we'll set a time for me to come out. Photos help, but I don't quote concrete off a phone call.
I measure and price it
I come out myself, look at the ground, the slope, what's around the job and how a truck or pump will reach it, then send you a written estimate you can compare line for line. You don't have to be home, but it helps if you are so we can talk through layout and finish.
We prep, pour and finish
Once you say go, we sort out anything the city needs, dig out and pack the base, set forms and pour early in the day so the top doesn't dry out too fast. Expect weekday work, because Walnut Creek requires an after-hours permit for construction on Saturdays and City Holidays and allows none on national holidays like Thanksgiving or Christmas.
Walk the finished job together
Before we leave, I walk the job with you and go over when you can walk on it and when you can drive on it. If anything isn't right, that's the time to tell me.
Questions about concrete work in Walnut Creek
Call (925) 503-1201You apply through the city's Online Permit Portal, because Walnut Creek no longer takes paper or emailed applications. The permit has to be signed by the legal property owner or a California licensed contractor, so either you sign it or we do as your contractor.
A small one often doesn't, because the city exempts retaining walls 4 feet high or less, measured from the bottom of the footing, that hold back 3 feet of soil or less. That exemption falls away if the wall carries extra load above it, like a driveway, a slope or a building, so I check the height and what sits behind the wall before I price it.
I can't give you a fair number until I've seen it, because a driveway's price comes down to its size, how much old concrete comes out and how much the ground has to be dug and graded. Thickness, rebar, the steel bars that hold a cracked slab together, and a stamped or colored finish all add to it. If the budget's tight, cut the fancy finish and keep the base, because a plain slab on a solid base holds up far better than a stamped one on loose dirt, and nobody can fix the base once it's poured over.
Most sinking starts with the base, when the old dirt was raked level instead of dug out and packed, so the slab drops as that loose dirt settles. Water getting under the edges speeds it up, so we dig down to firm subgrade, the ground the slab rests on, pack the base and set the grade so water runs off and away.
Concrete cracks, and I'd rather tell you that now than have you find out later. What we control is where, by cutting control joints, straight grooves that give the slab a planned place to crack, and cutting them on time, because joints cut late or skipped are how you end up with cracks wandering across the middle.
You'll usually be walking on it within a few days, and you'll wait longer before parking on it, because the slab is still curing and gaining strength. The exact days depend on the mix and the weather on pour day, so I give you both at the final walk-through, and you should plan on parking on the street in the meantime.
