Concrete Floor Installation in Brentwood, CA

That garage floor with the oil stains, cracks, and dusty surface that never stays clean? It's costing you more than you think.



A proper concrete floor installation transforms garages, workshops, and interior spaces from maintenance headaches into durable, easy-to-clean surfaces that last decades.


If you're searching for a concrete floor installation contractor near me , you've probably realized that not all concrete floors are created equal. The ones that fail within a few years? They skipped the steps you can't see.


At Brentwood Concrete & Masonry, we're a residential concrete floor contractor that does the invisible work that matters. Proper subgrade preparation, vapor barriers that actually work, reinforcement placed correctly—not just tossed in the general vicinity.


Our garage concrete floor installation process starts with understanding what you're parking, storing, and doing in the space. A floor for classic car storage needs different specs than one for a woodworking shop with heavy equipment.


As a concrete slab floor installation company , we handle everything from basic garage floors to polished interior concrete for modern homes. Our garage floor concrete pouring includes proper thickness (usually 4-6 inches depending on use), wire mesh or rebar reinforcement, and finishing techniques that create the surface you need.


The new concrete floor installation cost varies based on square footage, thickness requirements, existing floor removal, and finish options. But we provide detailed estimates upfront—no surprises when the work's done.


We're interior concrete floor contractors that work with homeowners doing modern renovations and businesses needing durable flooring solutions. Polished concrete, acid-stained finishes, epoxy-ready surfaces—we handle it all.


Call (925) 966-3740 today for a free estimate. We'll assess your space, discuss your usage requirements, and provide accurate pricing.


Stop dealing with floors that embarrass you. Get concrete that performs.

Frequently Asked Questions


  • How thick should a garage concrete floor be?

    Standard garage floors are 4 inches thick, but we recommend 5-6 inches if you're parking heavy vehicles, RVs, or storing equipment. The base preparation matters as much as thickness—a thinner floor on proper base outlasts a thick one poured on dirt.

  • Do concrete floors need vapor barriers?

    Yes, especially in garages and interior spaces. Vapor barriers prevent moisture from wicking up through the concrete, which causes coating failures, efflorescence, and that dusty surface that never stays clean. We install proper 10-mil poly barriers on all floor installations.

  • Can you pour concrete floors over existing concrete?

    Sometimes. If the existing slab is structurally sound and properly prepared, we can pour an overlay. But if there's significant cracking, settling, or moisture issues, removal and replacement makes more sense. We'll assess your situation honestly.

  • What's the difference between a concrete slab and a concrete floor?

    Functionally, they're the same thing—a horizontal concrete surface. "Slab" typically refers to the structural element, while "floor" refers to the finished walking/working surface. We handle both aspects of installation.

  • How long does garage floor installation take?

    Most single-car garages take 1-2 days, double garages 2-3 days. This includes removal of existing floor (if needed), base prep, forming, pouring, and finishing. You can walk on it after 24 hours but should wait a week before parking vehicles.

  • What finish options are available for concrete floors?

    We offer broom finish (standard texture), smooth trowel finish, exposed aggregate, polished concrete, and acid-stained finishes. We can also prepare surfaces for epoxy coatings. Each finish has different cost and maintenance characteristics.

  • How much does concrete floor installation cost in Brentwood?

    Costs typically run $6-12 per square foot for basic installations, more for decorative finishes or challenging site conditions. A standard two-car garage (400-500 sq ft) might range $2,400-$6,000 depending on specs. Call (925) 966-3740 for accurate pricing.

  • Do you install epoxy coatings on concrete floors?

    We prepare floors for epoxy application with proper grinding and cleaning, but we partner with specialized coating contractors for the actual epoxy installation. This ensures you get experts for each phase of the project.

  • What causes concrete floors to crack?

    Poor base preparation, inadequate reinforcement, improper curing, or ground settlement. We address all controllable factors during installation. Some hairline cracking is normal in concrete, but structural cracks indicate installation problems.

  • Can concrete floors be heated?

    Yes, radiant floor heating can be installed in concrete slabs. This needs to be planned before pouring since the heating elements are embedded in the concrete. We coordinate with HVAC contractors for these installations.
