How do you know it's time for a new patio?
Cracks and sunken corners
If the old slab has split and one side sits lower than the other, the ground under it has usually settled or washed out. Waiting lets more water get under the pieces, and the trip edges grow every season.
Water pooling by the house
Puddles that sit on the patio or run toward your wall mean nobody checked where the water goes before the pour. The longer that runs, the more it soaks the ground by your house and under the slab itself.
Chipping, dusty surface
A top that flakes, powders or wears rough usually means the concrete was finished in the heat or worked too wet. It doesn't heal, and patches rarely hold for long, so it tends to get worse each year.
What does it take to build a concrete patio in Duarte?
Concrete patio construction in Duarte means building a flat outdoor slab from the ground up. We dig out and pack the base, set forms, pour and finish the concrete, so you get a level place to sit, eat and walk that sheds water away from the house. Most of the time on a patio goes into the prep and the wait while it cures, not the pour itself.
Most people call because the old slab has cracked and sunk, or because the backyard is dirt and they're tired of tracking it inside. What moves the price is the size, how much digging and base work the ground needs, whether an old slab has to be broken out and hauled off first, how easy the yard is to reach and the finish you pick. The schedule turns mostly on the paperwork and the weather, because before we book anything we check whether your address falls under the city or the county and what that office needs, and we don't pour into the worst of the heat. Your estimate puts all of that on paper for your yard once I've seen it.

How we build a concrete patio
I look hard at the ground before we talk about finishes, because a pretty patio on a weak base doesn't stay pretty. I learned that on other people's crews after years in a warehouse, and the first lesson stuck. Raked dirt isn't a base. Our crew digs out the soft soil and packs the subgrade, the ground the slab sits on, until it's firm, since rebar, the steel inside the slab, holds pieces together but can't make up for weak ground underneath. We check where the water runs so the slab falls away from your house, set the forms and plan the pour so we're not finishing the top in the midday heat. Then we give it a surface we picked together that won't turn slick the first time the hose comes out, cut control joints, shallow grooves that give the concrete a straight place to crack instead of a random one, and let it cure, which is the wait while it hardens before you can put the furniture back. The base is the first thing people want to cut from the budget because nobody sees it on day one. It's the last thing I'll cut, since fixing it later takes a jackhammer. The whole job is backed by our satisfaction guarantee.
Patios are flatwork, our word for flat slabs like walks and driveways, and careful prep on flatwork is what we're best known for, so the connected work is easy to fold in. If you'd like the patio to look like stone or tile, stamped concrete is pressed into the same pour. If you need a path from the driveway or side gate, we can pour a concrete sidewalk at the same time so the two meet at the right height.
Work that often goes with a patio
Stamped concrete services
If a plain slab feels too plain, stamping presses a stone, brick or tile pattern into the concrete while it's still wet.
Concrete sidewalk building
A patio you can't reach without crossing wet grass gets less use, so a walk from the gate or driveway ties it in.
What happens after you call about a patio in Duarte?
Call or send a message
You call (626) 416-2143 or fill out the form, and I still answer the phone myself. We set a time for me to come see the yard.
I come look at the yard
I walk the ground, check where the water runs and ask a lot of questions about how you'll use the patio. You get a written estimate that spells out the base work, the finish and what's driving the price, so you can line it up against other quotes.
We check with the office
Before anything is scheduled we find out whether the city or the county handles your address and what the job needs from them, then tell you who's handling each piece. If Duarte wants a detailed plan check, the first review usually takes one or two weeks, so that wait goes ahead of the pour date.
Prep, pour and final walk
Our crew does the digging, base, forms, pour and finish while I'm on site checking the work, and when an inspection is required the city almost always comes out the next working day. When it's done, I walk the finished patio with you.
Questions before you build a concrete patio
How much does it cost to build a concrete patio in Duarte?
The price of a concrete patio in Duarte comes down to its size, how much digging and base work the ground needs, whether an old slab comes out first and the finish you choose. A plain broom finish usually costs less than stamped or other decorative work, and a backyard the truck can't reach takes more labor. I'll give you a figure for your patio after I've seen it.
Which concrete patio finish is safest when it's wet?
A broom finish, a light texture dragged across the wet concrete, is usually the safest choice for a patio that gets wet, because it gives your feet something to grip. A smooth trowel finish looks cleaner but can get slick under the hose or in the rain, and exposed aggregate, where the small stones show on top, adds texture but can feel rough on bare feet. Stamped and other decorative finishes ask more of the crew's timing and skill, and they're harder to patch and need more care over the years.
How do I find out if my patio needs a permit in Duarte?
Ask the city's Planning Division about your lot, because it's often the first stop for a permit and a planner can check your zoning, setbacks and other code rules. The city requires plans before building-related construction, but its list of examples names things like small additions and accessory buildings, not patios, so this one is worth asking about rather than guessing. If plans are needed, they go in at the Community Development counter because the city takes no online or email submissions right now, and the city collects a debris deposit it refunds once the project is done and it verifies 65% of the debris was diverted from the landfill.
Who can legally build a concrete patio in California?
A patio built for pay in California calls for a concrete contractor licensed by the state's Contractors State License Board, which defines that work as forming, pouring, placing and finishing flat concrete. The board's guidance only lets someone skip the license for minor work when the whole contract, labor and materials together, is under $500, and not when it's part of a larger project. We're fully licensed and insured, so that part is settled before I show up.
What causes a new concrete patio to crack?
A new patio usually cracks from a weak base, joints cut late or a pour finished in hot, windy weather. In the heat, fresh concrete sets faster, which makes it harder to finish and more likely to crack, and wind on top of high heat and low humidity makes it worse. It can happen any time of year but mostly shows up in summer, so if you're planning a summer pour, ask any crew how they'll handle heat and wind that day.
How soon can I seal a new concrete patio?
One patio guide says to wait at least 28 days after the pour before putting on any sealer. Sealer on concrete that hasn't finished curing traps moisture, and it can peel off or leave a white haze. Follow the directions from your sealer's maker as well, because they decide how that product goes on.
