What a new concrete patio fixes

Most patio trouble in Orange starts underneath, in a base that settles or holds water, and the cracks and dips it causes tend to spread the longer they sit.

  • Cracks across the slab

    Random cracks usually mean the ground moved or nobody cut control joints, the grooves that give concrete a planned place to crack. We cut ours on time.

  • Sinking or uneven sections

    A slab that's dropped or tilted usually sat on dirt that was raked level, not dug out and packed. We dig out and compact the base first.

  • Water pooling on the patio

    Puddles that sit after the sprinklers run, or water heading toward the house, mean the slab wasn't sloped right. We check where the water runs before we set forms.

  • Dusty, flaking surface

    A top that powders, flakes or chips usually means the concrete dried out too fast, often after a hot midday pour. We plan the pour around the weather.

Can you patch the old patio or start over?

If the cracks are thin and the slab still sits level, a repair can be enough. If it's sunk, tilted or holding water, the problem is underneath, and only a new base fixes that.

  • A repair is enough when:

    • Cracks are thin and not growing
    • The slab still sits level
    • Water drains off after rain
    • The surface is sound, not crumbling
    • Only one corner or edge is damaged
  • A new patio makes sense when:

    • Sections have sunk or tilted
    • Water pools or runs toward the house
    • Cracks keep spreading or reopening
    • The top is flaking across the slab
    • You want a bigger or reshaped patio

How your patio gets built

  1. Call or send a message

    You call (714) 787-1676 or use the form, tell us roughly how big the patio is and where it'll go, and we set a time to come out.

    A visit set up

  2. I look at the yard

    I come out myself, measure, check the ground and how water runs, and explain what I'd do and why before any price goes on paper.

    A plan in plain words

  3. Your written estimate

    You get a written estimate that spells out what's included and what isn't, so you can hold it up against anyone else's line by line.

  4. Permits and forms

    Once you say yes, we take care of any permit steps, then set the forms and check every one with a string line before the truck backs in.

    Forms set and checked

  5. Pour and clean-up

    We pour inside the city's work hours, 7 a.m. to 8 p.m. Monday through Saturday and 9 a.m. to 8 p.m. Sundays and city holidays, then clean up and walk the patio with you.

What our concrete patio work includes

  1. Layout and dig-out

    We mark out the patio, check which way water runs off the yard, and dig out soft soil down to firm ground.

  2. A packed base

    We spread base rock and compact it in layers so the subgrade, the ground the slab rests on, is firm and even.

  3. Forms and rebar

    We build the forms, check them for line and level, and add rebar, steel bars that hold the concrete together, where needed.

  4. Pour and finish

    We level the concrete and give it a broom finish, a light texture for grip, or a pattern with our stamped concrete services.

  5. Control joints

    We cut the joints on time, because joints cut late or skipped leave cracks in places nobody chose.

  6. Curing the slab

    We keep the slab moist through curing, the wait while it gains strength, so the top doesn't dry out weak and dusty.

What decides the price of a concrete patio?

Size sets most of the price, and the ground sets most of the rest. Breaking out and hauling off an old slab, digging deeper through soft soil, or wheeling concrete into a backyard the truck can't reach all add labor before anything is poured. Rebar or fibers add a little, and so do steps or a path out to the patio, which we can price alongside our concrete sidewalk building.

The finish is the other big choice, since a broom finish costs less than color or a stamped pattern. If the budget's tight, cut the finish before you cut the base, because nobody sees the base on day one but it's the part you can't fix without tearing the patio out. Timing turns on the forecast and any permit or inspection, and my written estimate lists all of it.

Why Orange homeowners call us for patios

I started on my own in Orange in 2017, and I still come out to look at every patio myself. On a patio I care most about the base and about keeping the slab wet after the pour, so I walk you through both at the estimate. We pick the pour day by the forecast, not just the calendar.

Our own crew does the work from the first form to the final cleanup, and I run a string line down every form before a truck backs in, the way my old foreman taught me. If part of what you want isn't worth the money, I'll say so. Call (714) 787-1676 and I'll come take a look.

Patio questions we hear in Orange

How much does a concrete patio cost in Orange County?

A concrete patio in Orange County usually costs about $6 to $35 per square foot. That's a wide range because the two local price guides behind it disagree sharply, with the 2026 guide toward the high end. Size, ground prep and finish decide where yours falls, and I put that in writing after I've seen your yard.

What causes cracks in a concrete patio, and will a new one crack too?

Most cracks start with poor base prep, which lets a slab settle, end up uneven in thickness and drain badly, and all three lead to cracking. Concrete also shrinks as it dries, so we cut control joints to give it a planned line, and fibers mixed into the concrete help control the small cracks that form while it's still fresh. No slab is crack-proof, but a packed base and joints cut on time make a big difference.

When is the best time to pour a concrete patio in Orange?

A mild, still day is best, because heat, wind and dry air all pull water out of fresh concrete before it's ready. That trouble mostly comes in summer but can happen any time of year, and wind and low humidity can dry out a pour on a cool day too. So we watch the forecast and stay out of the midday heat.

How do I make sure a new concrete patio cures properly?

Keep it moist while it gains strength, because in hot weather curing matters more than anything else about the job. Moist curing gives flatwork, flat slabs like patios and walks, its best strength and durability, so ask any contractor which method they'll use, whether that's ponding, wet sand, fog spraying or continuous sprinkling.

Do I need a permit for a concrete patio in Orange?

Ask the City of Orange Building Division, because the answer depends on your job, and the city takes every permit application through its Civic Portal. If wiring or plumbing will run under the patio, the city requires those lines to be inspected before the concrete goes in, and zoning rules vary by your home's district. When a permit is needed, we pull it, schedule the inspections and keep the approved plans on site, and I tell you up front what the city will want to see.

Who can legally build a concrete patio in California?

A licensed contractor, since the state's contractor board defines a concrete contractor as one who forms, pours, places and finishes flat and other concrete work. The license exemption covers only minor jobs under $500 in total, labor and materials included, and not work that's part of a bigger project. We're fully licensed and insured, and under state rules a home improvement down payment can't be more than $1,000 or ten percent of the contract price, whichever is less.
