Concrete contractor services in Sierra Madre, CA
Cornerstone Sierra Madre Concrete is a concrete contractor in Sierra Madre, CA, with 16 services for replacing cracked, sinking or uneven concrete and building new. Price follows the size of the job, how much old concrete comes out and the finish you choose, while the schedule turns on permits, ground prep and curing, the wait before new concrete can take weight. The estimate spells out each part for your job.

Concrete driveway building
We dig out the old driveway, pack a solid base and pour a new slab with a broom finish, a light texture that gives tires and shoes grip.

Concrete patio construction
A new concrete patio gives you a flat, solid place for a table and chairs, sloped slightly so water runs away from the house instead of toward it.

Stamped concrete services
Stamped concrete is pressed with patterns and colored while it's still soft, so a patio or walkway can look like stone or brick without the loose pieces.

Concrete sidewalk building
We pour new sidewalks and front walks on packed ground, with control joints, cuts that tell the concrete where to crack, so cracks usually land there.

Garage floor concrete
When a garage floor is cracked, stained or sinking near the door, we break it out and pour a new slab thick enough for the cars parked on it.

Decorative concrete
Decorative concrete covers colored, stained, exposed-stone and specialty finishes for homeowners who want a patio, entry or pool area with color and texture instead of plain gray.

Concrete retaining walls
On a sloped yard, a concrete retaining wall holds the hillside back, and we build it with steel reinforcing and drainage behind it so water doesn't push it over.

Concrete floor installation
We pour interior concrete floors for workshops, studios, additions and outbuildings, leveled and finished smooth so they're ready for sealing, coating or flooring on top.

Concrete pool decks
A concrete pool deck needs grip for wet feet and a slope that sends splash water away from the pool, and we build for both.

Concrete steps construction
We build concrete steps for front doors, back doors and slopes, with even step heights and rebar, the steel inside that holds the pieces together if a crack opens.

Slab foundation building
For a new garage, backyard unit or addition, we build the slab foundation, the concrete pad the walls sit right on, over a packed base with steel set inside.

Foundation installation
We dig, form and pour foundations for additions and new structures, built to the engineer's plans so the walls above sit square, level and on solid ground.

Concrete parking lot building
Apartment buildings, churches and small businesses get concrete parking lots from us with thicker slabs and drainage planned for cars coming and going all day.

Concrete footings
Footings are the concrete strips or pads under walls, posts, decks and additions, and we dig them to the depth your plans call for so the load spreads out.

Foundation raising
If floors slope, doors stick or cracks run up the walls because the foundation settled, we lift the low sections back toward level and support them there.

Concrete cutting
Concrete cutting means sawing clean openings, trenches for pipes and straight edges where old concrete meets new, which is work a jackhammer can't do neatly.
Why homeowners hire us for concrete work
Every step explained before we pour
We walk you through the base, the drainage and the joints in plain words, so you know what's going into the ground and why.
Same person from estimate to finish
I look at your job myself and run it on site, so the person you talked to is the one checking the work.
Base dug out and packed, not raked
We dig down to firm ground and pack it before we pour, because a slab on loose dirt settles and cracks right along with it.
Slabs sloped away from your house
We check where water runs on your lot and slope the slab away from the house, so it doesn't pool against your walls.
Pours kept out of midday heat
We pour in cooler hours when we can, because concrete that dries too fast in midday heat gets a weak, dusty top.
Permit paperwork handled for you
We find out early what the city or county needs and file the permit when one applies, so you know up front what's ahead.

Your concrete questions answered
How much does a new concrete driveway cost in Sierra Madre?
The cost depends mostly on the driveway's size, how much old concrete has to come out and how much digging and packing the ground needs, so we price each one after seeing it. A plain broom finish costs less than stamped or colored concrete, and a steep slope or tight access adds labor. The on-site estimate is free and spells out each part.
Why are some concrete quotes so much cheaper than others?
Usually the difference is under the slab, because the base is hidden on the day of the pour and it's the easiest place to cut. A crew that rakes dirt level instead of digging out and packing it can bid lower, and that slab tends to settle with the dirt. If the budget is tight, I'd rather simplify the finish than skimp on the base, and I'll show you where that choice sits in your estimate.
How long before I can drive on a new concrete driveway?
You can walk on new concrete well before you can drive on it, and the wait for each depends on the mix and how hot it is while it cures. I'll tell you both for your slab before we pour, so you can plan where to park in the meantime.
Does a concrete contractor need a license in California?
In most cases, yes, because California's Contractors State License Board requires a license whenever a job needs a building permit, uses hired workers or costs $1,000 or more in labor and materials. In Sierra Madre, a contractor also needs a City Business License before pulling a permit, even one based in another city. We're fully licensed and insured.
Do you tear out the old concrete before pouring a new driveway or patio?
Yes, in most cases we break out the old slab and haul it away, because new concrete poured over cracked or sinking concrete usually cracks along the old lines. Then we dig down to firm ground and pack the base before anything new goes down.
Do you guarantee your concrete work?
Yes, our promise is satisfaction guaranteed on every job. I also tell you before the pour what concrete can and can't do, so you know what to expect from the finished slab.
Will my new concrete crack like the old one did?
Hairline cracks show up in most concrete, but the wide cracks that sink or split usually come from a loose base, water getting underneath or joints cut too late. We pack the base, plan where the water runs and cut the joints on time, so the small cracks you do get usually stay in the joint lines.
Do I need a permit for concrete work in Sierra Madre?
It depends on the job, and the city's Building and Safety Division is the office to ask, since it issues building permits in Sierra Madre. The city's permit list also includes grading, drainage and excavation permits. We look into what your job needs before work starts and handle the application when one applies.

How a concrete job with us works
Call or send a message
Call us at (626) 828-0332 or send a message through our contact page with a few words about the job, like a cracked driveway or a bare side yard you want paved. We get back to you within one business day to set up a time to come see it.
Site visit and estimate
I come out myself, look at the ground, the slope and where the water runs, and ask how you'll use the space. Then I write up a free estimate that spells out each part of the job, from digging out to the finish, so you can see what you're paying for. There's no obligation.
We prep, pour and finish
Once you give us the go ahead, we sort out what the city or county needs. Our crew digs out and packs the subgrade, the ground your slab sits on, then sets the forms, pours, cuts the joints and finishes the surface. I'm on site running the job, so ask me anything as we go.
Curing and care walkthrough
Before we pack up, I walk you through curing and when the new concrete is ready for feet, then for cars. I'll also show you how to look after the surface and what to keep an eye on over the years, so you understand your own concrete and can ask good questions of anyone, us included.
