Concrete Contractor in Glendora, CA - Driveways and Patios Built for Sloped Lots
Modern Covina Concrete pours driveways, patios, steps, walls and garage floors for homeowners in Glendora, CA. We're a concrete contractor based in Covina, and we dig out and pack the base before any concrete goes in.
Glendora as we see it on the job
Glendora runs from flatter blocks on the south side up to streets that climb toward the foothills, and the work changes as you go up. Down low we mostly see driveways, patios and walks around single-family homes, a lot like what we pour in Covina and Azusa. Higher up, driveways get steeper, back yards come in levels, and the South Hills or the canyons sit right behind a lot of back fences.
That slope shapes most jobs here, because water runs downhill across every slab, and a driveway that climbs needs a base that won't settle and forms set to carry the water past the house.
Services in Glendora, CA
Concrete driveway building
Driveways that climb take a beating from tires and runoff. We dig out, pack the base and set the fall so water runs off the slab.
Concrete patio construction
Back patios here often sit against the house on a yard that tips toward it. We slope the slab away from your walls before picking a finish.
Concrete retaining walls
Terraced back yards on the hillside streets need walls that hold the dirt behind them. We pour them on footings with steel inside to carry the load.
Concrete steps construction
Raised lots often need steps up to the front door. We form every rise the same height and broom finish them, a light texture for grip.
Concrete sidewalk building
Side walks on sloped lots become the path the water takes around the house. We pitch them to carry runoff toward the street, not into your foundation.
Garage floor concrete
Garage slabs on older Glendora homes crack and chip after years of cars. For garage floor concrete we tear out the worn slab and pack new base under it.
Working in Glendora: permits, licenses and what moves the price
The city's Building & Safety Division issues building permits and inspections, and it's the office to ask whether your driveway or patio needs a permit. We check your address first to see whether the city or LA County handles it, and when a job needs a permit, we apply as the licensed contractor and set up the inspections, so those dates become part of your schedule. Glendora also requires every business working inside city limits to hold a business license, so ask any contractor you're weighing about theirs. We're licensed and fully insured.
The price on a Glendora job moves with the size of the slab, how much old concrete comes out, how deep the base work goes, the steel, the finish you pick and how far the truck sits from the forms, and on the hill streets that last one adds up. The schedule turns on any permit and inspection dates, the weather on pour day and curing, the days a slab needs before it takes weight, and your written estimate spells out what's included. We do the same flatwork in Charter Oak and down in Pomona, but Glendora's grades mean more forming, more thought about water and more care keeping the street and the neighbors' driveways clear.
What Glendora's hills and fire map mean for your slab
A lot of Glendora yards slope toward the street, toward a canyon or toward the house, and water follows that slope across and under every slab. When an old driveway has sunk at one corner or a patio holds a puddle by the back door, it's usually a base that was raked level instead of dug out and packed, or a slab that falls toward the walls. We dig down to firm subgrade, the ground the slab sits on, pack the base and check where the water will run before a single form goes in.
Glendora also has a fire hazard zone map adopted by the City Council, and the city's March 2025 count, made before adoption, put 5,149 acres in the very high zone. You can look up your own lot's zone with the city. Owners up near the brush often ask us about concrete patios, walks and steps right against the house, since concrete doesn't burn.

Glendora concrete questions we hear
How much does a new concrete driveway cost in Glendora?
The price comes from the driveway's size, how much old concrete comes out, and how much base work, forming and steel the grade needs. A steep or hard-to-reach driveway costs more to form and pour, and a stamped or colored finish costs more than a plain broom finish. I'll put your number in a written estimate after I measure.
How do I apply for a building permit in Glendora?
You apply online through the city's Civic Access portal, since Glendora no longer takes permit applications by email. You need an account to start, and the portal is where plans get uploaded, review status shows up and inspections get scheduled. On our jobs that need a permit, we file it as the licensed contractor.
Will my new concrete driveway crack like the old one?
It may still get a hairline crack, because all concrete shrinks as it cures, but a slab on a packed base with control joints cut on time cracks where we planned it, not across the middle. Control joints are the grooves we cut on purpose so the crack runs straight along them. When an old slab sank or broke up, it's usually the base, and that's the part I won't cut to save money, because a nice finish on a weak base breaks just the same.
How long does new concrete take to cure before I can drive on it?
You can walk on a new slab well before you can park on it, because concrete keeps gaining strength for days after the pour. Heavy use too early can mark or crack a slab that already looks done. We tell you the walk-on and drive-on days for your slab before we pour, so you can plan where the cars go.
Can you pour a concrete driveway on a steep lot in Glendora?
Yes, steep driveways are a regular part of the work here, they just take more prep. We dig out and pack the base, add rebar, the steel that holds the slab together if it cracks, and give the surface a broom finish so tires and shoes grip. The steeper the grade, the more forming and water planning it takes, and that shows up in the estimate.
What happens to the old concrete when you tear out a driveway in Glendora?
We break it up and haul it off as part of the job, so it doesn't sit in your yard. The city's Building and Safety page says state law requires construction and demolition projects to recycle or reuse 65% of their waste debris, and covered projects have to submit a waste management plan. If your job falls under that, we'll tell you when we look at the permit side.
Ask about your Glendora driveway or patio
We answer the phone evenings and weekends, so call (626) 412-8842 or send the form when you get home and see that crack again.
