Self-leveling concrete for floors inside your house

  • Kitchen slabs before tile

    A thin pour over the existing slab takes out the dips and humps, so new tile sits flat and doesn't rock on a high spot.

  • Basements and other indoor floors

    Basement floors and other interior slabs with minor unevenness get a smooth, flat surface that's ready for the flooring you've picked to go over it.

Will self-leveling concrete fix an uneven floor in Martinez?

Self-leveling concrete is a thin overlay we pour across an existing indoor floor in Martinez to take out minor dips and humps, so your tile, plank or carpet goes down on a smooth, flat surface.

Most people call when tile or plank is on the way and the old floor rocks under a straightedge, or when flooring comes up and leaves a patched, uneven slab. It's indoor work, because a leveling maker's own guide says its self-leveling underlayments are for interior use only. The price moves with the room's size, how far out of flat it runs, what has to come off first and whether there are cracks to plan around, and the schedule turns mostly on the moisture test and what shows up under the old floor. California's contractor license board describes a flooring contractor as one who prepares any surface for flooring and a concrete contractor as one who pours, places and finishes flat concrete, so ask anyone you're comparing how they handle the prep as well as the pour. At Stonefield Martinez Epoxy Flooring, I look at the room first, and my written estimate spells out the prep and the pour for your floor.

Grinding, priming and leveling, in that order

I look at the slab, what's on it and how far out of flat it runs before I set the prep. This is indoor work, so a pool slab is a job for pool deck coatings and resurfacing.

  • Old flooring comes up

    Vinyl, tile or glue on the slab comes off first through our concrete floor stripping and removal work, since the pour needs bare concrete to grab.

  • Moisture test before pouring

    We test the slab for moisture before anything gets poured, so we know it's ready to take the overlay and the floor above it.

  • Grind and prime

    Our crew grinds the high spots and old residue, then primes the slab, so the overlay holds on instead of cracking or coming loose.

  • Pour and level

    We pour the self-leveling layer across the room so it fills the low spots and leaves a flat base for your new floor.

Why Martinez picks Stonefield for floor prep

I taught myself floor coatings on my own garage, learned the rest beside experienced crews and started this business in Martinez in 2017. A floor that fails usually started with a slab nobody tested or ground right, so we spend our hours on prep before anything gets poured.

  • I look at your floor myself

    I come out to see the slab and write the estimate, and I'm on the job with our crew through the prep and the pour, so nothing gets lost along the way.

  • Licensed and fully insured on every job

    We're licensed and fully insured, which matters when grinders, primers and heavy bags of material are moving through your house for a few days.

  • The plan explained before you sign

    Before you sign anything, I walk you through the moisture test, the grinding and any cracks or glue we found, and why each one is in the price.

Questions about leveling a floor in Martinez

How much does self-leveling concrete cost in Martinez?

Across the US, self-leveling concrete poured over an existing indoor floor usually runs about $4 to $10 per square foot installed. That's a national range, not our price, and where your room lands depends on how uneven it is, what has to come off first and how much grinding it needs. One cost guide counts prep like grinding high spots in that price, so ask whether each quote you get includes it.

Can I use self-leveling concrete on a patio or outdoor slab?

No, this product is for indoor floors. One maker's guide says its self-leveling underlayments are for interior use only, and we use it on floors inside the house. If your project is outside, call and we'll talk about what that slab needs.

Why does my slab need a moisture test before self-leveling?

Because a slab holding too much moisture can wreck the floor after it's in. A standards body for concrete testing notes it can cause debonding, or coming loose, along with peaking and decay of flooring and coatings, plus microbial growth. Flooring makers generally require a moisture test on concrete before installation, and we test before we pour.

What causes self-leveling concrete to crack after it's poured?

Cracks or joints in the slab that still move are a common cause. One maker's guide says that movement can carry up through the self-leveling layer and crack the finished floor, so that guide carries those joints and cracks up through the new layer and the floor covering instead of pouring over them. Skipped prep is the other usual cause, which is why we grind and prime first.

How do I deal with old floor glue before leveling a floor?

If it's cutback adhesive, the black glue found under a lot of older floors, get it tested for asbestos before anyone removes it. One maker's guide says all cutback adhesive should be tested before removal and rules out sanding any that contains asbestos. Plan for that test if your old floor has glue under it.

Who issues building permits in Martinez?

The city's Building Department issues them through its Permit Center. All new applications, residential ones included, now go in electronically through the city's online portal. The permits line is (925) 372-3515, and permitting hours are Monday to Friday, 8:00 to 11:30 a.m. and 1:00 to 4:00 p.m.

Self-leveling concrete and overlays in Martinez

The Martinez Building Department issues building permits to homeowners and licensed contractors for work inside city limits. Whether leveling an indoor floor needs one isn't something I'll guess at, so the department is the place to ask before work starts. If your job needs a permit, we sort out with you which city or county office covers your address and who pulls it, then we work with that office from there.

We're based in Martinez and take jobs across Contra Costa and Solano counties, and a lot of the floors we level are kitchens and basements in older houses, where years of patches and old flooring leave a slab that won't take tile flat. We see the same floors on jobs in Concord and Pleasant Hill, and we prep them the same way.
