Concrete driveway building in Sierra Madre CA - a driveway built on a firm base
Cracked, sinking or puddling driveway? We dig out soft ground, build a firm base and pour a slab that stays even.
What goes into building a new concrete driveway in Sierra Madre?
Concrete driveway building in Sierra Madre means taking out the old slab, digging down to firm ground, packing an even base, and then pouring, finishing and curing a new slab so it resists settling and structural cracking.
Most calls start with an old driveway that's cracked through, sunk at one corner or holds a puddle after every rain. The price moves with the size of the driveway, how much old concrete and soft ground has to come out, how thick the slab is, whether the approach at the street gets replaced and how plain or fancy the finish is. The schedule turns mostly on the base work, the weather on pour day and the cure before you can drive on it. We're based in Sierra Madre and work in Pasadena, Arcadia, Monrovia and many other cities around them, and I'll give you your own number once I've come out and looked at your driveway.
How we handle concrete driveway building
Most of the work on a driveway happens before any concrete shows up. We break out the old slab, dig out soft spots and refill them with gravel or crushed rock, then pack the base, the layer your slab sits on, until it's firm and even, because a base that's only raked level settles with the dirt and takes the concrete down with it. Before we set the forms, we check where the water runs and slope the slab toward the street and away from your house and garage. We also leave an isolation joint, a soft break, where the new concrete meets your garage floor or a sidewalk so each one can move on its own. We talk through slab thickness with you before the pour. After we pour, we give it a broom finish, a light brushed texture that gives tires and shoes some grip. Then we cut the control joints, straight grooves that give the slab a chosen place to crack, on a layout we've already put in writing. Curing starts as soon as finishing ends, and we help you sort out parking while it does. If the budget gets tight, I'd rather you skip a fancy finish than skimp on the base, because you can dress up a surface later, but you can't fix what's under it without tearing it all out. Does that make sense?
A lot of driveway jobs run into other flatwork, the flat concrete around a house. If the backyard needs attention too, a concrete patio can go in while our crew and forms are already here. If you'd like the driveway to be more than plain gray, stamped concrete presses a stone or brick pattern into the surface, often just as a border along the edges.
Why Sierra Madre homeowners call Cornerstone Sierra Madre Concrete for driveways
I write every estimate myself
I come out myself to look at your driveway and write the estimate, and once work starts, our crew does it with me on site running the job. You're dealing with the same person from the first walk-through to the last pass of the broom.
In business since 2020
I started this business in 2020 after years on concrete crews around the San Gabriel Valley, and before that I mixed concrete for barn floors on our family farm. The farm taught me that a slab is only as good as the ground under it, which is why the base gets most of our time.
Fully licensed and insured for driveways
We're fully licensed and insured, so you aren't left carrying the risk if something goes wrong on your property. California licenses concrete contractors for forming, pouring and finishing flat work like driveways, and it's worth asking any contractor which license they carry.
City permits sorted before we dig
Before work starts, we look into what your driveway needs from the city or county, and when a permit applies, we handle the application as the licensed contractor and walk you through each step. In Sierra Madre this matters most when the job replaces the approach, where your driveway meets the street.
What decides how a driveway holds up is the part you won't see once it's poured, so ask any contractor how they'll build the base. When you're ready, send us your driveway details or call (626) 828-0332. It helps to know the rough size, whether the approach at the street is changing and any questions you have about your soil.
Get a free on-site estimate for your new driveway
We get back to you within one business day to set a time, and then I come out myself to look at the driveway, the ground and the street edge, and I write up the estimate. It's free and there's no obligation, so you can compare it and ask questions before you decide anything.

Questions before you build a concrete driveway
How much does a new concrete driveway cost around Sierra Madre?
In the Los Angeles area, an installed two-car concrete driveway of 400 to 600 square feet usually costs about $1,700 to $6,000 per job. Where yours lands depends on the size, how much old concrete and soft ground has to come out, the thickness and the finish.
How thick should a concrete driveway slab be?
It usually comes down to 4 inches or 5. One concrete guide figures the extra inch adds about 20% to the concrete bill but carries nearly 50% more load. If you park a truck or heavier vehicles, that trade is usually worth making, and we'll talk it through with you before anything goes in writing.
How long does new concrete need to cure before I can drive on it?
Plan on at least a week before you drive on it, which is what one concrete guide advises. Curing is the wait while the concrete gains its strength. It starts right after finishing, and skipping it can leave the slab weaker, so set up other parking for that week.
Does replacing the driveway approach in Sierra Madre need a city permit?
Yes. The City of Sierra Madre issues permits for digging or building in the street, curb, gutter, sidewalk or parkway, and that includes replacing a driveway approach. A Public Works permit doesn't replace other permits, and grading permits go through the Planning Department. If you're unsure what applies, the city asks you to call the Public Works Department at (626) 355-7135 before work begins. Inspections need at least 24 hours notice, and the work has to stay uncovered until it's approved, so we build that wait into the schedule.
What causes cracks in a concrete driveway, and will mine crack?
Concrete shrinks as it dries and moves when the ground under it settles, so most driveways crack somewhere, and random cracks are generally not a structural problem. Wire mesh or rebar, the steel laid inside the slab, holds a crack together if one forms. Synthetic fibers cut down on shrinkage cracks but add no structural strength. Good joints and a firm base do the rest.
How does hot or windy weather affect pouring a concrete driveway?
Heat, wind and dry air pull water out of fresh concrete fast, which can leave a weak, dusty top. A concrete industry guide notes that hot weather trouble mostly shows up in summer, but wind and low humidity speed drying even on cooler days, so a windy, sunny pour day calls for more care than a calm, humid one. That's why we watch the forecast and stay away from pouring in the midday heat.
Other concrete work around your driveway
- Concrete patio construction
A backyard slab built on the same packed base and drainage checks as your driveway, sloped away from the house so rain runs off instead of sitting by the door.
- Stamped concrete services
When plain gray feels too plain, a pressed pattern that looks like stone, brick or tile can dress up a driveway border, a front walk or a patio.
