What goes into building a concrete patio in Pomona?
At J&K Pomona Concrete Contractors, concrete patio construction in Pomona means digging out the soft ground behind your house, packing and sloping what's left, then forming, pouring and finishing a slab that sheds water and stays flat under chairs, a grill and a lot of foot traffic.
Most people who call about a patio have bare dirt out back, or an old slab by the back door that's cracked, sunk or holding water. The price moves with the size, how much soft dirt has to come out and get hauled away, whether there's an old slab to break out first, how easily we can get concrete into the yard and the finish you pick. The schedule turns on the weather, any permit the city wants and the cure before you can use it, and you'll get your own figure in the written estimate I send after I've looked at the ground. If the budget gets tight, cut something on top and leave the base alone, because the base is buried on day one and it's the part that decides whether the slab stays flat.
How do you know your old patio needs replacing?
Cracks wandering across it
Cracks that run wherever they like usually mean the joints were cut late or skipped, so the slab picked its own lines. A few hairline cracks aren't a crisis, but once the edges start lifting they catch toes and chair legs, and water getting underneath makes the next crack easier.
Water sitting by the house
A puddle along the back wall after the sprinklers run usually means the slab was poured flat or tipped toward the house instead of away from it. Leave it and that water keeps soaking the ground right beside your house every time it runs.
One section has dropped
When one corner or panel sits lower than the rest, the dirt under it is usually settling because it was raked level instead of dug out and packed. It tends to keep dropping, and the lip it leaves is exactly where people trip.
How we build a concrete patio
A patio is only as good as the dirt under it, so we start there. We dig out the topsoil and soft spots, compact the subgrade, which is the ground the slab sits on, and slope it so water runs away from the house. Then we set the forms, place rebar, steel bars that hold the slab together if it cracks, and pour, tooling the edges clean and cutting control joints, shallow lines that give the slab a place to crack where we chose instead of where it wants. After that comes curing, the wait while the concrete holds its moisture and gains strength, and it's the step people most want to rush. You pick broom or smooth, and I'll tell you honestly which one gets slick when the hose is running.
If you want the slab to look like stone or brick instead of plain gray, that's stamped concrete, and it goes on the same prepared base. A patio usually needs a way to get to it, too, so we often form a concrete sidewalk from the driveway or side gate and pour it along with the patio.
Broom finish
A broom finish is the fine ridges left by dragging a stiff broom across the wet surface, and those ridges are what give your feet some grip. It's the common pick for patios that get wet from hoses, sprinklers or kids running in from the yard.
Smooth trowel finish
Smooth troweled concrete looks cleaner, but it can get too slick when it's wet. I steer people toward it only for small, covered spots or areas nobody walks on much.
Get a written estimate for your new patio
We reply within one business day to set a time for me to come out. The estimate is free, done on site and written down, and there's no pressure to book. I look at the ground, measure and ask how you'll use the space before I put a number on paper.
(909) 729-4086What to know about concrete patio construction in Pomona
Pomona's Building & Safety office decides whether a patio needs a permit, and the city's building forms page lists a Patio handout, so it's a question worth asking before anyone digs. I won't guess at it for your job, and you shouldn't take anyone's guess either. The walk-in counter at City Hall is open Monday to Thursday, 7:30 a.m. to 6 p.m., and the number is 909-620-2371 if you'd like to ask yourself. When a job needs a permit, we pull it and handle the paperwork with the city.
A lot of the Pomona backyards we work in sit behind a narrow side yard, and plenty have an old slab poured straight onto dirt by the back door. I measure the gate on the estimate visit because access decides how the concrete gets back there, and an old slab means breaking out and hauling before the digging starts. We see the same kinds of yards on jobs in Claremont and La Verne.
What happens after you call about a patio
Call or send a message
Call (909) 729-4086 or use the form, and we'll get back to you to set a time for me to come out.
I walk the yard and measure
I check the ground, measure and ask how you'll use the space, then send a written estimate covering the price, how we'll prep and slope the base and the finish we talked about. You see the number on paper before anyone digs, so you can compare it with anyone else's.
We set the pour day
Any permit the job needs comes first, and that paperwork is on us. Pour days fall inside Pomona's construction hours, Monday to Saturday between 7 a.m. and 8 p.m., with no work on federal holidays.
We pour and walk it together
My crew forms, pours and finishes while I check the work, and then the slab has to cure before it takes furniture and a grill. Before we pack up, we walk the finished patio with you.
Frequently asked questions
How much does a concrete patio cost per square foot in Pomona?
Installing a concrete patio usually runs about $10.50 to $12.50 per square foot across the US, and that's a national figure, not our price. What yours costs depends on your yard, which is why I measure and look at the ground before I write a number down.
How do I keep a new concrete patio from cracking?
You can't stop concrete from cracking entirely, but properly planned control joints decide where the cracks go and keep them small. That's why the joints get laid out before the pour instead of guessed at afterward, and a packed, sloped base under them does the rest.
Can an unlicensed contractor pour a concrete patio in California?
Only on a very small job, because California counts building a patio as home improvement work. The state's minor work exemption now covers jobs up to $1,000, up from $500, and it applies only when the work needs no permit and the person doing it has no employees. Past that, you want a licensed contractor.
How long does a new concrete patio need before sealing?
One patio company's guide says to wait at least 28 days after the pour before any sealer goes on. Sealer on concrete that hasn't finished curing traps moisture underneath, and it can peel or leave a white haze.
Can you pour a concrete patio on a hot day in Pomona?
Yes, but the pour should be planned around the heat, because concrete finished in the middle of a hot afternoon tends to end up with a weak, dusty top. When possible, crews place and finish outside the hottest part of the day and don't sprinkle water on the slab to make finishing easier. On summer jobs we start early so the finishing is done before the worst of it.
What should I ask a concrete contractor before they build my patio?
Ask how they'll prepare the ground, because all the topsoil and soft spots should come out and what's underneath should be well compacted and sloped for drainage. Ask how they'll cure the slab, too, since curing should start right away with a sprayed curing compound or damp burlap kept moist for at least 3 days. Then ask where the joints will go.
