Garage floor concrete in Berkeley CA - a slab built for what you park on it

Cracked, dusty or sinking garage floor? We pour a new slab with the thickness and base your vehicles and future plans call for.

What should you ask for in a new garage floor?

Garage floor concrete in Berkeley is a slab poured on the ground under your garage, built to carry what you park on it, from a sedan to a pickup or an RV, and to stay flat under that weight.

Most people call because the old floor is cracked, sinking at a corner, pooling water or shedding dust, or because they're building a garage and want the slab right the first time.

The price moves with the size of the garage, how thick the slab has to be for your vehicles, how much digging and base work the ground needs and whether you want it ready for a coating later. The schedule turns on any permit, the weather on pour day and the curing, the wait while the concrete hardens before you can park on it, and your own figure for all of it comes in the written estimate after I've measured.

  • Thickness set by what you park, from passenger cars up to pickups and RVs.
  • A dug-out, packed base and a check of where water runs before we form.
  • A plain broom finish, or a slab set up for a coating or a heated room.

What happens after you call about a garage floor?

I'd rather you know how this goes before anyone picks up a shovel. Here's the path from your first call to the day you park on the new floor, and who handles each part.

  1. Call or send a request

    Call (510) 345-1330 or send the form, and have ready the garage size, what you park and any plan to coat or heat the floor. We'll set a time for me to come out.

  2. I measure and explain choices

    I come out myself, measure the garage, look at the ground and how water moves around it, and go over thickness, base and finish with you. You get a written estimate that spells out the slab, the price and what's included, so you can compare it with other bids.

  3. We prep, pour and finish

    Once you say yes, we take care of any permit steps, then our crew preps the ground, forms, pours and finishes the slab with me running the job. You'll need somewhere else to park while it cures, and the questions below cover how long.

  4. We walk the finished floor

    I walk the new floor with you and explain how to care for it in the first weeks, including when it's ready for your car. Your satisfaction, guaranteed.

How we pour garage floor concrete, start to finish

The first thing I ask is what you park in there and whether you'll coat or heat the floor someday, because both change how we build the slab, so we settle those answers before the pour, not after. Then our crew digs out the subgrade, the ground the slab sits on, and packs it firm, because a base that's only raked level settles with the dirt and the floor goes with it. We check where water runs so the slab falls toward the door and not the house, set the forms and any rebar, pour early in the day so midday heat can't leave a weak, dusty top, and cut control joints, shallow grooves that give shrinkage cracks a straight line to follow, before the slab picks its own spots. If the budget gets tight, I'll steer you to keep the base and give up something on the surface, because nobody sees the base on day one but it's what keeps the floor flat.

A garage job often touches the ground around it. If you'd like the apron or a side path to have color or pattern, we can do that as decorative concrete, and if the yard steps up beside the garage and the dirt needs holding back, we build concrete retaining walls too.

  • A plain broom-finished floor

    This suits a working garage that stays unheated and bare, where you want grip underfoot and nothing to peel. A broom finish is a light brushed texture that gives tires and wet shoes something to hold.

  • A slab planned for a coating or a finished room

    This suits you if epoxy, polyaspartic or a heated workshop is anywhere in your plans, because those choices change what goes under the slab. It's far easier to build for it now than to wish later that we had.

Garage floor questions we hear from Berkeley homeowners

These are the questions people ask me most before a garage pour. The thickness and wait figures are general industry guidance, not Berkeley rules, so treat them as a starting point we'll fit to your floor.

How thick should a garage floor be for a pickup or RV?

Four inches is standard practice for passenger cars, and industry guidance moves to 5 or 6 inches for pickups and RVs approaching 12,000 pounds. Slabs that thick or that heavily loaded will often need reinforcement too, usually rebar, steel bars set in the concrete that help it handle settling ground, heavy loads and shrinkage as it dries.

How much does a garage floor slab cost in the Bay Area?

A standard 4-inch slab with a basic broom finish usually costs about $13 to $18 per square foot installed in the Bay Area. That's the going rate around here, not our quote, and a thicker slab, rebar or a vapor retarder will move your number, which you'll see in the written estimate after I measure.

How long does new concrete take before I can park in my garage?

Concrete typically needs at least 7 days before you park a passenger car on it, and 7 to 14 days for heavier vehicles. Most concrete can take light foot traffic 24 to 48 hours after the pour, so you can walk through well before you drive in, but line up another parking spot for that week or two.

Do I need a vapor barrier under a garage floor I plan to epoxy?

A vapor retarder is worth having if you plan an epoxy or polyaspartic coating, or want to heat and finish the garage later, because a slab passes vapor up from the soil and the retarder slows it. It's a sheet that goes under the concrete, so it has to be decided before the pour, while a bare broom-finished floor in an unheated garage doesn't need one.

Where should the joints go in a two-car garage floor?

A 20 by 20 two-car garage at 4 inches wants at least one joint each way, which splits the floor into four roughly square panels. Ask where the joints will go before the pour, because no slab comes crack-free and the joints are how you choose where the cracks land.

How do I check a concrete contractor's license in California?

Look the contractor up with the state licensing board's online license check, which shows license information and any complaint disclosure. The state lets an unlicensed person take small jobs up to $1,000, up from $500, but only when the work needs no permit and they employ no one, so it doesn't cover anyone bringing a crew to pour your floor. We're licensed and fully insured.

Garage floor concrete in Berkeley and nearby cities

Berkeley's Permit Service Center issues permits, and the city says to assume you need one for work not on its exempt list, so we check before pricing and handle any permit. We do the same work in Oakland and Albany.
