Concrete Floor Installation in Lancaster CA - A Flat Slab Ready for Your Flooring
Planning a new floor and worried it'll crack or ruin the flooring on top? We pour a slab that's flat and ready for it.

What a new concrete floor needsbefore anything goes on top


A concrete floor is the slab everything else sits on, so if it's out of level, cracked or damp, the tile, wood or carpet on top pays for it. Concrete floor installation in Lancaster starts with the subgrade, the dirt the slab sits on, because a floor is only as flat as what's under it.
Before we pour, I ask what flooring is going on top, because that decides how flat and how dry the slab needs to be. We dig out and pack the base instead of raking it level, then set rebar, the steel that holds the slab together.
The price comes down to the size of the room, how much digging and base work it needs, how thick the slab is and how close the truck can get. The schedule turns on whether the city reviews plans first, the weather on pour day and the curing wait. I'll give you your number in writing after I measure.
Call (661) 952-4153 and you'll know what goes under your floor and what it costs before we pour a yard of concrete.
Concrete floors we pour and finish
We start with what the floor has to carry and what's going on top of it. If it meets a back door or the yard, we also build concrete steps and pool decks.
Under tile, wood or carpet
A floor that gets covered has to be flat and dry, so we build it to the flatness your flooring installer needs and protect the vapor barrier through the pour.
Garage and shop floors
These carry cars, tools and heavy shelves, so we ask what's parking or rolling across the floor and set the base and steel to match.
Room additions
A new room's slab has to meet the old floor at the doorway, so we set our forms to the existing height before anything gets poured.

Why people hire L&M Lancaster Concrete Constructionfor floors that come out level
You talk to me when I come out to measure, and you see everything in writing before we start, so there's no guessing what you're paying for.
Trained crew, owner at the pour
I trained our crew the way an old-school foreman trained me, forms straight or torn out. I'm on site for the pour.
Pouring concrete since 2013
That's 13 years of floors, flatwork and foundations under one rule, because concrete doesn't give you a second try.
Fully licensed and insured
We carry a contractor's license and insurance, so you're not taking on the risk of somebody uncovered working inside your house.
The base gets the budget first
Nobody sees the base once the slab is down, which is why it's the first thing people want to cut. We won't, because a floor goes wherever the dirt under it goes.
Satisfaction guaranteed on every job
That's the promise, and it's why I'd rather pass on a job than pour something I'd have to apologize for later.

Permit and groundwork
We sort out any permit, and Lancaster's first plan review usually runs 2 to 3 weeks unless the job is small enough to check over the counter. Then we dig out and pack the base.
Pour, finish and cure
We pour and finish the floor, then cure it, which is the wait while we keep the slab from drying out too fast so the top stays hard.
Walk it with you
We walk the floor with you before we call it done, so you can see it's level and the joints sit where we planned them.
Questions we get asked
How much does a new concrete floor cost in Lancaster?
A new concrete slab, installed, usually costs about $5 to $17 per square foot in the Los Angeles area. That's a broad guide pulled from more than one estimate, not a Lancaster price, so treat it as a starting point. I'll give you your own figure in writing after I measure.
Will my new concrete floor crack?
It might, because no slab is completely crack-proof, but well-planned control joints keep cracking in check. Those are grooves cut into the slab so it cracks along a line we picked instead of across the room, and we lay them out before the pour. Wire mesh won't stop cracks either, though it tends to keep them from opening up.
How do I keep moisture from ruining flooring on a new concrete slab?
Start with an unbroken vapor barrier, the plastic sheet laid under the slab. One vapor barrier maker found that even small holes can let a lot more moisture up through the floor, which can make flooring fail or hold up the install. Our crew patches any tear before concrete covers it.
What is the best way to pour and cure concrete in hot weather?
Pick the right time to pour, then cure it properly. In hot weather the surface can lose water faster than it comes up from below, which dries the top and cracks it early, so one supplier's guide says to pour at the cooler times of day or night, and that can move your pour day. Curing protects the new floor from dry air, wind and big temperature swings, and doing it wrong can leave shrinkage cracks and a flaking surface, so ask any contractor how they'll cure yours.
Who can pull a permit for a concrete floor in Lancaster?
In Lancaster, only a licensed contractor or a property owner who lives in the home can pull a permit, and an owner's permit is for a house the owner alone uses and occupies. The city's Building & Safety office issues permits, reviews plans and inspects during the work. If you pull it yourself, set up an Accela account first so you can track it and book inspections.
Do I need a licensed contractor to pour a concrete floor in California?
Yes, unless the whole job is $1,000 or less and needs no permit. California lets unlicensed workers take minor work up to $1,000 only under those conditions, and only if they have no employees. The state licensing board has a concrete contractor class for work that forms, pours, places and finishes flat concrete, which covers a new floor.
