Should you resurface the floor or replace it?
Garage floor work runs from resurfacing the slab you have to pouring a new one, and that choice sets most of the price and how long your car sits outside.
Resurfacing will do when:
- Cracks are fine and level
- Both sides of each crack sit even
- Cracks aren't getting wider
- The floor isn't sinking or heaving
- The top is pitted, stained or flaking
Replacing makes sense when:
- One side of a crack sits higher
- Cracks keep growing
- Sections have sunk or lifted
- Water pools on the floor
- The base underneath has settled or washed out

A visit on the calendar
I look at the floor
I come out, measure the garage, check the cracks and how level the floor sits, and explain whether I'd resurface or replace it, and why.
A clear recommendation
Your written estimate
I send a written estimate that spells out what's included and what isn't. If you plan to coat the floor later, we settle that now, before any work starts.

Permits and prep
Once you say yes, we pull any permit the job needs and schedule the inspections, then dig out, pack the base and set the forms.
A job ready to pour
Pour, clean up, walk through
Our own crew pours and finishes the floor and cleans up, then I walk the finished work with you and answer anything you want to know.
A finished floor
What a garage floor job includes
Tear-out and haul-away
When the slab has to go, we break it up and haul it off so the new floor starts on clean ground.
Dug-out, packed base
We dig to the subgrade, the ground the slab sits on, and pack a base that supports it evenly and drains well.
Forms set to drain
We set and check the forms so edges run straight and water runs out the door, not toward the house.
Steel held off the ground
Rebar or mesh, the steel that holds cracks tight, sits on small supports called chairs so it stays mid-slab during the pour.
Control and isolation joints
Control joints give cracks a planned line, and isolation joints free the slab from walls, posts and the door line.
Overlay on a sound slab
When the slab is solid, we clean and prep the old surface and bond a thin overlay to it.
What sets the price of a garage floor?
The biggest thing that moves the price is whether we resurface the slab you have or tear it out, because a new floor adds demolition, hauling, base work, steel and fresh concrete. After that it comes down to the size of the garage, how much digging and packing the ground needs, and how close we can get the truck to the door. Your written estimate lists each of these.
If the budget is tight, I'd cut the finish before the base. A decorative concrete look or a coating can go on later, but the base is buried the day we pour, and a slab on raked, loose dirt settles with it no matter how good the top looks.
Why Orange homeowners call us for garage floors
I come out to look at every garage floor myself, and I look hard at the cracks and how level the slab sits before I say anything about price. If resurfacing will do, I'll tell you, and if something isn't worth doing, I'll tell you that too. Every job is backed by our satisfaction guarantee.
I learned under a foreman who ran a string down every form before he'd let a truck back in, and I still do it that way because the ground, the forms and the steel are what keep a floor flat. We've been in business since 2017, we're based in Orange, and our own crew also builds driveways, steps and concrete retaining walls across the cities around it.

(714) 787-1676Garage floor questions we hear
Can I fix a garage floor crack myself?
Usually yes, if the crack is level and under 1/4 inch wide. If one side sits higher, the crack keeps growing, or the floor is sinking or heaving, call a contractor, because the problem is under the slab and not on top of it.
Should I resurface or replace my garage floor in Orange?
Resurface it if the slab is sound and only the surface is worn, and replace it if the slab itself has failed, because replacement is the only real fix for structural trouble. I check the cracks and the level of the floor first, so you don't pay for a new top on a floor that's still moving.
How much does a new garage floor cost in Orange, CA?
A garage floor in Los Angeles County usually costs about $8 to $15 per square foot, so treat that as a rough guide to the market, not our price. Where yours lands depends mostly on whether it's resurfaced or replaced and how much base work it needs, and your written estimate spells out what the price covers.
How do I apply for a building permit in Orange, CA?
You apply online through the city's Civic Portal, because the Building Division takes permit applications only that way. The city's permit technicians help owners figure out which permits a project needs and what the fees are, so they're the ones to ask about your garage floor. If we're doing the job, we handle the permit steps, and I'll tell you up front what the city will want to see.
Do I need a licensed contractor to replace a garage floor in California?
If anyone brings a crew, yes. California lets someone without a license take on work only up to $1,000, and only when it needs no permit and they employ no one, so ask any crew bidding on your floor for its license. We're fully licensed and insured.
How long should a new garage floor cure before I coat it?
One coating maker's guide asks for 28 days of curing, the wait while new concrete hardens and dries, and it counts a freshly resurfaced floor as new too. Follow your own coating maker's instructions, and tell us early if you plan to coat, because moisture rising through a slab can make some coatings peel, warp or change color.
