Concrete work on Pittsburg homes, rentals and shops
The short answer: C&K Pittsburg Concrete Company is the concrete contractor I started here in 2021, and I still come out to look at each job myself. We pour driveways, patios, walks and foundations across Pittsburg, CA, and we take on the harder jobs too, like cutting into an old slab, building a wall on a steep yard or raising a house that's settled.
Most of our Pittsburg calls are flatwork, the driveways, patios, walks and garage floors that lie flat on the ground, plus steps and the odd wall. Around Old Town and the streets toward the waterfront, a lot of the houses are older, and their walks and steps have usually been patched more than once. Rental owners call us when steps and walks need fixing before a tenant trips, and shop owners call about floors and small lots. We do the same work next door in Antioch.
On an older house, I want to know what's under the slab before we break it up or cut into it, because old pipe, wire or a thin, cracked base can be hiding there. On a sloped lot, where the water runs matters as much as the concrete.
Why Pittsburg slabs crack, sink and hold water
Most of the cracked, sinking or uneven slabs we look at here failed from underneath. Somebody raked the dirt level instead of digging down to the subgrade, the firm soil a slab sits on, and packing a base over it, so the concrete settled right along with the loose dirt. The other one we see a lot is a driveway or patio that tips toward the house, which sends rainwater at your foundation and leaves puddles by the door. We dig out to firm ground, pack the base and check where the water will run before we set a single form. That base is the part you can't see on day one and the first thing people want to trim from the budget, and it's the last place I'd cut, because a nice finish on a bad base cracks just the same.
Rentals, shops and small lots take harder use than most backyards, with cars and tenants on them every day. On those we talk about slab thickness and rebar, the steel bars inside that hold the slab together if it cracks, before we talk about color. On walks and steps we usually go with a broom finish, a light texture dragged across the top so it isn't slick when it's wet.
Concrete services we offer in Pittsburg
Concrete driveway building
When your driveway has cracked, sunk at the edges or holds water by the garage, we tear it out, rebuild the base and pour a new slab.
Concrete patio construction
For a backyard that's bare dirt or an old patio that tips toward the house, we pour a new one that drains away from your walls.
Stamped concrete services
When you want a patio, walk or entry that looks like stone or brick, we press the pattern into fresh concrete and seal the color in.
Concrete sidewalk building
When a front walk has heaved, cracked or sunk into a trip edge, we replace the bad sections or the whole run so it's level again.
Garage floor concrete
When a garage floor is cracked or sloped the wrong way, we pour a new slab that drains toward the door and holds up to daily parking.
Decorative concrete
For an entry, path or patio you want to stand out, we add color, exposed stone or a custom edge to the concrete you already need.
Concrete retaining walls
On a sloped yard where dirt keeps slipping onto a patio or drive, we build a concrete wall with drainage behind it so water doesn't push it over.
Concrete floor installation
For shops, sheds, additions and work spaces that need a flat, hard floor, we prep the ground and pour a slab ready for what goes on it.
Concrete pool decks
Around a pool, the deck has to shed water away from the pool and the house, so we slope it right and give it a textured, less slippery finish.
Concrete steps construction
When front or back steps have cracked, settled or pulled away from the house, we form and pour new ones with even rises that are easy to climb.
Slab foundation building
For a new house, addition, garage or accessory unit sitting on a slab, we prepare the ground, set the steel and pour to the approved plans.
Foundation installation
When a new building or addition needs a perimeter foundation instead of a slab, we dig, form and pour it to the plans for your job.
Concrete parking lot building
For a shop, rental or small business lot, we pour parking areas thick enough for daily traffic and sloped so rain runs to the drains.
Concrete footings
For a deck, fence, wall, carport or addition, we dig and pour the footings that carry the weight down into firm ground under it.
Foundation raising
When a corner of the house has dropped and doors stick or floors slope, we lift the settled section back up and support it from below.
Concrete cutting
When you need an opening for a door, drain or pipe in an old slab or wall, we saw it clean and check what's inside before we cut.

What we know from working in Pittsburg
In Pittsburg, the city issues the permits, and its Building Division runs a job from the first application to the final inspection, so when a permit is needed, our pour date waits on the city. Rules differ from one city to the next, so I check with the building office early in planning, walk you through what they tell us and take care of pulling the permit when the job needs one. The city also requires every business working in Pittsburg, subcontractors and out-of-town companies included, to hold a current City of Pittsburg business license before the work starts, and a county license only covers the unincorporated areas, so it's worth asking anyone you hire to show you theirs. We're fully licensed and insured.
What moves the price here is mostly the size of the slab, how much old concrete comes out and gets hauled off, how much base work the ground needs, how close we can get a truck and the finish you pick. The schedule turns on the permit when there is one and on the weather, and your estimate spells out what's included for your job. We price and plan jobs the same way in Bay Point and Concord.
How it works when you call us about a Pittsburg job
Here's how a concrete job in Pittsburg goes with us, from your first call to the walk-through at the end. I'm the one you'll see at the start, and I'm on the job with our crew.
- Step 01
Call or send the form
Tell us what's going on with your slab, and we'll set a time for me to come out. You don't need measurements yet.
- Step 02
I walk the site with you
I look at the base, the drainage and anything hiding in the old concrete, and I ask a lot of questions, so it helps if you're home. Then I write an estimate that says what's included and what isn't, so you can see where the money goes.
- Step 03
Permit, then the pour
If the city requires a permit, the start date follows its approval and inspections, and I'll keep you posted on where that stands. Once it's clear, I run the job with our crew, from tear-out and base to forms, pour and finish.
- Step 04
Clean up and walk it together
When the concrete's in, we clean up the site and walk the finished job with you. I'll tell you when it's ready for feet and when it's ready for cars.
Pittsburg concrete questions we hear most
Do I need a permit for a concrete driveway in Pittsburg, CA?
Often, yes, because the city lists concrete work, grading and any work in its right of way, the public strip along the street, among the jobs that need an engineering construction permit. A driveway that meets the street usually touches at least one of those. After the first visit, I'll tell you which parts of your job fall under it.
How long do I have to start work after a Pittsburg building permit is issued?
The city gives the permit holder 180 days from issuance to start the work and get an inspection, or the permit expires and is no longer valid. The holder can ask for one 180-day extension. When we hold the permit, we plan the pour around that window.
How do I find out what permits and fees my Pittsburg concrete job needs?
Ask the city directly, because its online OpenCounter tool is for general guidance only, and city staff make the final call on permits, fees and zoning. The tool is a fine place to start reading. It's also why I check with the building office early instead of going on a guess.
How much does a concrete driveway cost in Pittsburg, CA?
There's no set price, because each Pittsburg driveway is priced from what I see on site, and the written estimate lists what's in it. A sunken driveway usually costs more than a worn one, since the old base has to come out and new base has to go in, and work that reaches the street can add city permit fees and inspections. If you're weighing finishes, ask me to price a plain broom finish and a decorative one side by side.
What causes concrete driveways to crack and sink in Pittsburg?
Usually it's what's underneath: a loose base, water running under the slab, or control joints that were cut late or skipped. Control joints are shallow cuts that give the concrete a straight line to crack along as it shrinks, so we cut them as soon as the slab can take the saw. No slab is crack-proof, but a packed base and joints in the right places usually keep cracks small and the slab level.
How long until I can drive on a new concrete driveway in Pittsburg?
You'll walk on it well before you drive on it, because the slab keeps curing, slowly hardening and gaining strength, for days after the pour. I give you the days for foot traffic and for cars when we set the pour date. In warm weather we pour early in the day, because midday heat can leave the top weak and dusty later.
