Pittsburg homes and the concrete around them
Pittsburg sits on the water where the Sacramento and San Joaquin Rivers come together. The houses run from older places around Old Town to neighborhoods built later, farther from the river. Most of our calls here are for the everyday concrete around a house, like a driveway cracked across the middle, a patio that has settled toward the back door or a front walk that catches people's toes. It's much the same mix we see next door in Antioch and Bay Point, and we drive out from Concord for it.
On the older lots, the slab we're replacing was often laid on dirt that was raked flat instead of dug out and packed, so before I price anything I want to see what's underneath and where your yard sends its water.
Concrete work we do around Pittsburg homes
Concrete driveway building
For Pittsburg driveways that have cracked across or sunk at the garage edge, we break out the old slab, dig out and pack the base and pour new.
Concrete patio construction
A backyard patio should fall away from the house, so we set the slope before the pour and rain runs to the yard, not toward your foundation.
Stamped concrete services
Stamped concrete presses a stone or brick pattern into the fresh slab, which suits front walks and patios on older homes where plain gray feels out of place.
Concrete sidewalk building
When a front walk cracks or one section lifts and starts tripping people, we cut out the bad sections and pour new ones that sit flush with the rest.
Garage floor concrete
Older garage floors get pitted, stained and cracked from years of cars and oil, and we pour a new slab that's level, smooth and easy to sweep.
Decorative concrete
Colored and textured finishes for patios and entries, with the color picked out on site so you can see how it looks against your house before we commit.
Concrete retaining walls
On a sloped yard, a poured retaining wall holds the hill back so the patio or driveway stays put, with drainage behind it so water can't push it forward.
Concrete floor installation
Slab floors for shops, sheds and additions, poured level and finished smooth so flooring goes down right on top or the concrete can stay bare.
Concrete pool decks
A pool deck needs a surface that isn't slick under wet feet and a slope that sends splash water away from both the pool and the house.
Concrete steps construction
Front and back steps on older homes often settle or crumble at the edges, and we form new ones with even heights so nobody misjudges a step.
Slab foundation building
For additions, garages and backyard units, we pour slab foundations on a dug-out, packed base with rebar, the steel inside that holds the slab together if it cracks.
Foundation installation
When something new goes up on a Pittsburg lot, we dig, form and pour the foundation it stands on, built to the plans your permit is issued for.
Concrete parking lot building
For small property owners with apartment or shop lots, we pour parking areas that carry daily traffic and shed water instead of holding puddles.
Concrete footings
Footings are the concrete pads under posts, walls and covers, and we dig them deep and wide enough that a patio cover or fence doesn't start leaning later.
Foundation raising
When part of a house or slab has settled, raising lifts it back toward level, and I'll tell you first whether raising or replacing makes more sense.
Concrete cutting
We saw-cut old slabs for removal, openings and new drain lines, and we cut control joints, the planned lines that tell a slab where to crack.

Working in Pittsburg: permits, licenses and what moves the price
Inside Pittsburg city limits, permits go through the city's Building Division, which handles each step from the application to the final inspection, so the permit and its inspections set part of your schedule. The city's OpenCounter tool online gives general guidance, but city staff make the final call on permits, fees and zoning, so I check with them about your address and job, and we handle the paperwork when a permit is needed. There's also something you can check on any contractor. The city requires everyone doing paid work in Pittsburg to hold a current City of Pittsburg business license before they start, out-of-town businesses and subcontractors included, and a Contra Costa County license only covers the unincorporated parts of the county. We're licensed and insured.
Price here turns on a few things you can see from the curb. On the tighter streets near Old Town, it matters whether the concrete truck can reach your pour or we have to wheel or pump it in. The finish matters too, because a plain broom finish, the light texture swept in so it isn't slick when wet, costs less than stamped or colored work. The one place I won't cut corners is the base, because it's buried on the first day and it's what keeps the slab from sinking, so if the budget is tight I'd rather cut back the finish. You'll get your own figure in writing after I've seen the site, the same way we work in San Ramon and the other cities around Concord.
Why Pittsburg driveways and patios crack and sink
A lot of the concrete around older Pittsburg homes has been down for decades, and much of it went onto dirt that was raked level and never dug out or packed. That's like setting a table on a pile of loose laundry. The ground keeps settling, the slab goes down with it, and you end up with the cracks, sunken corners and trip edges people call us about. We dig down to firm subgrade, the soil the slab rests on, pack a base on top of it and add steel where the job calls for it.
The other thing we see is water. A slab that tilts toward the house sends runoff at your foundation and leaves puddles that stain and chip the surface, so before we set forms I check where your water runs and give the new slab a fall away from the house.
How a concrete job in Pittsburg goes, start to finish
Here's what happens between your first call or message and the walk-through at the end, and the points where it helps to be home.
Call or send a message
Call (925) 536-0945 or use the form and tell us what you're dealing with, such as a cracked driveway or a new patio. We get back to you and set a time for me to come out.
Walk the site together
I look at the old slab, the ground and the drainage with you, explain each choice and what it means for cost and upkeep over the years, then put the estimate in writing. You can take your time with it, and it's best if you're home for this visit so I can show you what I'm seeing.
Permits, then the pour
Once you're set, we sort out the city side and schedule any inspections the permit calls for. Then we break out, dig, pack the base, set forms and pour, with me on site alongside our form setters and finishers.
Walk the finished job
When it's done, I walk it with you, show you where the control joints are and why they're there, and tell you when it's ready to walk and drive on. You don't need to be home during the pour itself.
Questions about concrete work in Pittsburg
How do I find out if my concrete job needs a permit in Pittsburg, CA?
Ask the city before work starts, and plan on one being likely, because the City of Pittsburg requires an engineering construction permit for concrete work, grading and work in the city's right of way, the public strip along the street that usually takes in the sidewalk and curb. I check what your address and job call for before we schedule anything, and we handle the paperwork when a permit is needed.
How long do I have to start work after a Pittsburg building permit is issued?
Work has to start, and the permit holder has to get an inspection, within 180 days of the permit being issued, or the permit expires and is void. The holder can ask the city for one 180-day extension, but I'd rather not need it, so we line up the pour before the permit is pulled.
How much does a new concrete driveway cost in Pittsburg?
The size of the driveway and the work underneath it set most of the price, more than the concrete itself. Breaking out and hauling off the old slab, how deep we dig for the base, how thick the slab has to be to carry a car and whether the permit adds fees all show up in the total. I give you a written figure after I've seen the site.
How long does it take before I can drive on a new driveway in Pittsburg?
You walk on it well before you drive on it, because curing, the wait while fresh concrete gains strength, keeps going long after the top looks dry. I'll give you the walk-on and drive-on dates for your slab and the weather at the time, and we tape it off so nobody tries it early.
Will my new concrete patio in Pittsburg crack like the old one?
Concrete does crack, so the real goal is cracks that land where we planned them and stay tight. That's what control joints are for, and cutting them on time matters as much as cutting them at all, along with a packed base and steel that keep the pieces level. On hot days we pour early, since a slab that dries too fast in midday heat ends up with a weak, dusty top.
Who handles sewer connection permits for a new slab or addition in Pittsburg?
The Delta Diablo Sanitation District handles sewer connections for Pittsburg and the areas around it, and the city's Building Division points people there. If a drain or sewer line will run under your new slab, it needs to be settled before we pour, because once the concrete is down, reaching that line means cutting.
