Services in Ontario, CA

Concrete driveway building

Older Ontario driveways often crack and sink because nobody packed the ground first. We break out the old slab, pack a new base and pour.

Concrete patio construction

Many newer tracts came with a small slab out back. Our concrete patio construction extends it, sloped so rain runs away from the house.

Concrete sidewalk building

Front walks on older houses here lift and leave trip edges as roots and settling push sections out of line. We replace the bad panels.

Concrete steps construction

Front steps on older homes here chip at the edges and pull away from the house. We form new ones and pour them on packed ground.

Stamped concrete services

Backyards in the newer tracts often get a plain gray slab nobody loves. We stamp and color new concrete, but only after the base under it is right.

Concrete cutting

Sometimes only one sunken section of an old driveway needs to go. We saw a straight, clean cut so the new concrete meets the old edge neatly.

Ontario, CA properties and local conditions

A lot of the driveways we look at on Ontario's older streets were poured decades ago, often on dirt that was raked flat instead of dug out and packed. The subgrade, the soil the slab sits on, settles over the years and the slab sinks with it, and the cracks land wherever the concrete decided to break because nobody cut control joints, the shallow grooves that give a crack a straight place to happen. Some of these slabs also tip back toward the garage, so every rain leaves a puddle at the door. We break the old slab out, dig to firm ground, pack a new base, set the slope so water heads for the street, and cut the joints in time so the cracks go where we chose.

The newer tracts are a different call. The base under those houses is usually in better shape, but the backyard slab tends to be small, and people want room for a table and a grill. When we add on, we match the height of what's there and keep the new section falling away from the house. My old boss liked to say concrete remembers everything you did to it, and that goes double where new meets old.

What matters when we pour concrete in Ontario

In Ontario, building permits come from the city's Building Department, which reviews plans and inspects the work, so whether your driveway or patio needs a permit is the city's call, not mine. When a job needs one, we pull it and handle the paperwork, and the work moves at the pace of the city's plan review and inspections, which is the one part of the schedule nobody can rush. Before you hire anyone here, check two things. California requires a license from the Contractors State License Board for most concrete jobs, and the city requires a business license before any contractor works in Ontario, whether the company is based in the city or outside it. We're fully licensed and insured.

What moves the price here is the size of the slab, what has to come out before we start, how deep we dig for the base, and the finish you pick. The schedule turns on the permit, if there is one, and on curing, the wait while concrete hardens enough to take weight, which keeps you off a new driveway longer than a walkway because a car is heavier than you. Your own figure comes in the written estimate after I've seen the ground. Ontario is a short run from Pomona on the I-10, so getting out to look at your place is easy, and it's the same work we do in West Covina and Rancho Cucamonga.

What happens after you call us about an Ontario job

  1. Call or send the form

    Call (909) 729-4086 or send the form with a few lines about the job. We get back to you and set a time for me to come out.

  2. I come look at the ground

    I look at the ground, measure and ask how you'll use the space, since a slab for a truck is built differently than one for patio chairs. Then you get a written estimate that lists what's included, so you know what you're paying for before you decide.

  3. We pull permits and pour

    If the job needs a permit, we pull it, and the work follows the city's review and inspection schedule. My crew forms, sets rebar, the steel bars that hold a slab together if it cracks, where the job needs it, then pours and finishes while I check the work.

  4. We walk the job together

    We walk the finished slab with you before we pack up, so plan to be home for this part. We also tell you when you can walk on it and when you can park on it while it cures.

Frequently asked questions

Do I need a licensed contractor to pour a driveway or patio in Ontario, CA?

Yes, for nearly any real driveway or patio job. California requires a state contractor's license for any job that needs a building permit, uses workers, or comes to $1,000 or more for labor and materials combined. The only way around it is a small job with no permit, no workers and less than $1,000 in total, and a bigger job can't be split into small contracts to get under that line.

How much can a contractor ask for up front on a concrete job in California?

The state licensing board says a contractor can't ask for or take a down payment of more than $1,000 or 10 percent of the contract price, whichever is less. After that, payments are listed in the contract and follow the work done or the materials delivered. That covers home improvement jobs like a driveway or patio, so it's worth checking any bid you get against it.

How much does a concrete driveway cost in Ontario, CA?

The biggest factor here is usually whether an old driveway has to come out first, because breaking out and hauling off old concrete is work you pay for before anything new goes down. Thickness and finish move it too, and a broom finish, a light texture dragged across the top for grip, costs less than stamped and colored concrete. If the budget's tight, cut the finish, not the base, because a plain slab on good ground outlasts a fancy one on soft dirt, and I'd rather lose a bid than pour on bad ground.

What causes concrete driveways to crack and sink in Ontario?

Usually it's the ground underneath, when the base was raked level instead of dug out and packed and then settled over the years. Water getting under the slab and missing control joints make it worse. A new slab can still crack, since all concrete shrinks as it cures, but on a packed base with joints cut in time the cracks usually stay in the joints and the slab stays put.

Does Ontario charge to extend a permit on a concrete job?

The first extension request on a plan check or permit is free, and each further extension the city grants costs $150 on a residential permit and $300 on a commercial or industrial one. When your job needs a permit, we line up the work so the permit isn't left sitting.

How do I stop water from pooling on my concrete patio?

On an existing patio, the fix is usually replacing the low section, because pooling means the slab sank, was poured flat or tips toward the house. A coating on top doesn't change where the water runs. On a new patio we set the forms so the slab falls away from the house and check where the water goes from there, so it doesn't end up at your foundation or your neighbor's fence.

About Ontario, CA

Ontario mixes older neighborhoods close to downtown with newer tracts farther out, and a good deal of commercial and industrial property in between. On the older streets we see narrow driveways, front walks and steps that have been patched more than once, and yards with mature trees whose roots lift concrete. In the newer tracts the houses sit closer together and the side yards are tight, which changes how we get forms and concrete to the backyard.

It's the same mix we work with in Montclair and Chino. Either way, the job starts underneath, with whether the ground under the old slab or the new pour will hold.
