Patch the old floor or pour a new one?
If the old slab is flat, dry and only damaged in spots, a repair may do, and I'll tell you so. If it's sinking, damp or blocking new plumbing, a new floor makes more sense.
A repair is enough when:
- Cracks are hairline and not growing
- The floor is still flat and level
- Only a small area is damaged
- No dampness comes through
- Your covering hides small flaws
A new floor is better when:
- The slab has sunk or tilted
- Cracks keep widening or lifting
- Moisture keeps coming up
- Plumbing or wiring must go underneath
- Your new covering needs a flat, dry base

A reply from us
I come out and measure
I look at the ground and ask what flooring goes on top, because that decides where the vapor barrier sits and how we plan around drying.
A plan in plain words
Your written estimate
You get a written estimate that spells out what's included and what isn't, so you know exactly what you're paying for before anything starts.
A written estimate
Permit, forms and barrier
Once you say yes, we file any permit your job needs with the city's Building Division through its online portal, then set the forms and barrier for inspection.
Ready for inspection
Pour, finish and clean up
We pour and finish within the city's work hours, 7 a.m. to 8 p.m. Monday through Saturday and 9 a.m. to 8 p.m. on Sundays and city holidays. Then we clean up and walk the floor with you.

What our concrete floor installation includes
Dig-out and subgrade
We dig to firm ground and grade the subgrade, the soil the slab rests on, so the floor gets an even bed.
Packed base
We compact the base in layers instead of raking it flat, because loose fill settles and the slab goes with it.
Forms set and checked
We set forms to your finished floor height and check them for line and level before the truck arrives.
Vapor barrier, inspected
The barrier goes where your covering needs it, and Orange inspects it and any under-slab plumbing or wiring before we pour.
Rebar on supports
Rebar, the steel bars inside the slab, sits on supports so it ends up within the concrete, not under it.
Finish and joints
We finish the top to suit your flooring, adhesive or coating, and cut the control joints before the slab can crack on its own.
What shapes the cost of a new concrete floor?
Size is the biggest piece, then the ground. Firm, flat soil costs less than ground we have to dig out, haul away and replace with packed base, and some parts of Orange County have expansive soil, clay that swells when wet and shrinks as it dries. If money's tight, I'd rather spend it on the base than the finish, because nobody can get back under a slab once it's poured.
Steel adds cost, and reinforced slabs run more than plain ones. The covering matters when it calls for a particular barrier setup and more drying time, and a floor the truck can't reach adds work too. Stain or stamping is separate. Your estimate lists each item.
Why homeowners in Orange call us for floors
I learned concrete under a foreman who checked every form with a string line, and I've run things the same way since starting in Orange in 2017. I come out to each job myself, and our own crew does the work, the same crew behind our concrete pool decks and concrete steps. If something isn't worth doing, I'll tell you. Call (714) 787-1676 to set up a visit.

How much does a new concrete floor cost in Orange, CA?
A concrete slab in Orange usually costs about $7 to $14 per square foot, going by one local cost guide. That guide puts reinforced slabs above plain pads, and its figures leave out staining or stamping. I'll give you your own number in a written estimate once I've seen the site.
How long does a new concrete floor take to cure before I can walk on it?
You can usually walk on a new slab within 48 hours, though concrete takes about a month to fully cure. One cost guide suggests waiting a week before heavier loads, so plan on light foot traffic first and heavier use later.
Will my new concrete floor crack?
Some random cracking should be expected in any concrete floor, even with joints cut close together, according to industry floor guidance. Steel won't stop cracks, but properly sized and placed reinforcement should keep them tightly closed, so we plan the steel and joints together. Our work is backed by our satisfaction guarantee.
How do I keep moisture from ruining flooring laid over a new slab?
Ask where the vapor barrier will sit, because industry floor guidance says a barrier directly against the slab best protects floor coverings and coatings. Wet fill above the barrier can make the slab take much longer to dry. That's why I ask about your flooring before we start.
Does someone need to be home for a concrete slab inspection in Orange?
Yes, when the inspector needs to come inside, because City of Orange inspectors won't enter a home unless someone of legal age is there. They also need full access to the work area, so we'll let you know which days to keep it clear.
Do I need a licensed contractor to pour a concrete floor in California?
California licenses contractors for this work through the Contractors State License Board, which has a concrete classification covering forming, pouring, placing and finishing flat concrete. State law also counts work on garages, basements and patios as home improvement, which the board licenses too. We're fully licensed and insured.
