Services in Montclair, CA
Concrete driveway building
A lot of Montclair driveways are the original pour, cracked and sunk from decades on raked dirt. We break them out, pack a real base and pour new.
Concrete patio construction
Old patios here often settle toward the house, so rain sits against the wall. We pour new ones with a slight fall away from your house.
Concrete pool decks
Older pool decks here have cracked or lifted away from the pool's edge. We rebuild the pool deck on packed ground with a textured finish for wet feet.
Concrete sidewalk building
Yard trees and decades of settling leave front walks with trip edges between sections. We break out the lifted pieces and pour level ones on a packed base.
Garage floor concrete
Older Montclair garages often have cracked, stained floors that dropped near the door. We break the slab out and pour a new one sloped toward the door.
Concrete footings
Patio covers and room additions on older houses need footings sized to the plans. We dig, set the rebar that holds the concrete together and pour.
Montclair, CA properties and local conditions
Much of Montclair is older single-story houses, and a lot of the concrete around them is the original pour. By now we usually find driveways sunk along one edge, walks lifted by roots and patios cracked straight across. When I break one out, the trouble is usually the subgrade, the soil the slab sits on, because it was raked smooth instead of dug out and packed. We dig down to firm ground, bring in base, compact it in layers and pour on that, since concrete only stays as flat as what's under it.
The ground here is mostly flat, so water won't run off a slab unless someone sets the slope on purpose. The city has projects designed for rain of up to 2 inches an hour, which is a lot of water looking for somewhere to go. Before we form anything, I check where it runs today and set the slab to carry it away from your house.
What changes when your concrete job is in Montclair
Building permits in Montclair come from the city's Building Division at City Hall, and whether your slab needs one is their call to make, not mine. When it does, we pull it and handle the paperwork, and the permit adds a trip to the counter and the city's inspections to the schedule. The city lets any properly licensed state contractor pull a permit, and asks to see the pocket copy of the license and proof of workers' comp insurance before it issues one. Every business working in the city also needs a Montclair business license, good for one year, so it's fair to ask any contractor you're weighing for both. We're fully licensed and insured.
We're based next door in Pomona, and we pour in Montclair the same way we do in Chino Hills and the other cities around us. Price here comes down to the size of the job, how much old concrete has to come out, how much base the ground needs, the finish and whether a truck can back up to the forms or we need a pump to reach a backyard. The schedule turns on the permit, the weather on pour day and curing, the days the concrete needs to harden before you walk or drive on it. You get your own figure in a written estimate once I've seen the ground.

Call or send us a message
Call (909) 729-4086 or use the form and tell us what's going on with your driveway, patio or walk. We'll set a time for me to come out.
I look at the ground
I walk the job, check where water runs, measure and ask how you'll use the space, so it helps if you're home. Your estimate spells out the demo, the base work and the finish, so you can compare bids line for line.
We pull permits and pour
If the job needs a permit, we take it to the counter at City Hall and schedule the city's inspections. My crew forms, pours and finishes, and I'm on site to check the work.
Walk the finished job together
Before we pack up, we walk the job with you and look over the edges, the joints and the drainage. I'll tell you when it's ready to walk on and when to drive on, because curing can't be rushed.
Frequently asked questions
How do I get a building permit for concrete work in Montclair?
Most permits in Montclair are pulled in person at the counter at City Hall, and the fees can be paid by check, cash or credit card. City staff review any drawings and come out to inspect the work while it's going in, and you can read the city's permit steps yourself. When we do the job, we make that trip and handle the paperwork.
Can I pull my own permit for a patio or driveway in Montclair?
Yes, the city offers an owner-builder permit for homeowners doing the work themselves. You'd sign a form exempting you from workers' comp insurance and agree to comply if you later become subject to those rules. If we pour it, the permit goes in under us instead.
What building code does Montclair use for concrete work?
Montclair has adopted the 2025 California Building Standards Code, and for houses that means the California Residential Code with some changes of the city's own, including its fees and penalties. When a job needs a permit, that's the code the inspection checks against, so we build to it from the forms up.
How do I find out if my Montclair house is on sewer or septic?
File a Public Records Request for the building permits on your address, online or at City Hall, and the city will send any permit records it has for a sewer connection. It's worth knowing before a new patio or driveway goes in, because you don't want a slab poured over a septic tank someone will need to reach later.
How much does it cost to replace a concrete driveway in Montclair?
There's no honest number until I've measured your driveway and seen the ground under the old one, and you get that figure in writing after the visit. The part people want to cut first is the base, because nobody sees it once the concrete's down. I'd go the other way and save on the finish, since a plain broom finish, the light brushed texture that gives tires and shoes some grip, costs less than stamped work, and a fancy top on soft ground cracks just the same. I'd rather lose a bid than pour on bad ground.
What causes concrete driveways in Montclair to crack and sink?
Most of the cracked, sunken slabs we break out here were poured on raked dirt with no packed base, and water got under them. Midday pours and late joint cuts add to it, so we pour early and cut control joints, grooves that give the slab a planned place to crack, while the concrete is still young. Nobody can promise concrete won't crack, but those steps decide where it cracks and whether it stays level.
About Montclair, CA
Montclair is a small city with Pomona and Claremont on its west side and Ontario to the east. Here, like across the area, most calls come from homeowners on blocks of older single-story houses, with some from property managers looking after apartments and the commercial lots along the busier roads.
A lot of the work here is flatwork, the driveways, walks and patios that sit right on the ground, around houses that have been standing a long time. Lots are modest and side yards are often narrow, and the old concrete usually has to come out first, so demo, access and base work shape a Montclair job as much as the pour does.
