Oak Park concrete work, right across the county line

We're a concrete contractor based in Agoura Hills, CA, and Oak Park sits just over the county line from us in the valleys of the Simi Hills, with Westlake Village also on its south side and North Ranch in Thousand Oaks to the west. It isn't its own city. It's an unincorporated part of Ventura County, and we work both sides of that line, over to Calabasas and the cities around it.

Building here started in 1967 and the neighborhoods were finished before 2010, so plenty of the driveways, patios and front walks I look at are original or close to it. The calls start with a crack, a section that's dropped or water pooling by the garage, and most of the time the cause is under the slab, not in it. The price turns mostly on how much old concrete comes out and how much base we have to rebuild, the schedule turns on the cure, the wait before you can use it, and your own number comes from the written estimate. With houses set into hilly ground, the grade of your lot and where the runoff goes shape the job as much as the concrete does.

Why older Oak Park slabs crack and sink

  • A lot of older driveways sat on dirt that was raked level, not dug out and packed, so we rebuild the subgrade, the ground the slab rests on, first.
  • On sloped lots, a patio or driveway poured without checking where the water runs can end up falling toward the house, so we set the grade before the pour.
  • Cracks that wander across an old slab usually mean the control joints, the cuts that tell concrete where to crack, went in late or not at all, so we cut ours on time.

Concrete services we offer in Oak Park

  • Concrete driveway building

    When an original Oak Park driveway has sunk or split across the middle, we tear it out, rebuild the base and pour a new slab sized for your cars.

  • Concrete patio construction

    For a backyard patio that's cracked, uneven or holding water after a rain, we reset the grade so water runs away from the house, then pour.

  • Stamped concrete services

    Stamped concrete gives a patio or entry the look of stone or brick in one pour, and it holds up only as well as the base under it.

  • Concrete sidewalk building

    Front walks that have heaved or tipped are a trip hazard, so we replace them with a broom finish, a light brushed texture that gives shoes grip.

  • Garage floor concrete

    A garage floor that's cracked, stained or sloping the wrong way can be broken out and repoured so it drains toward the door, not the house.

  • Decorative concrete

    Colored and textured concrete lets you match a newer patio or walkway to your house, and we talk through finishes at the estimate so the budget stays honest.

  • Concrete retaining walls

    On lots cut into the hills, a concrete retaining wall holds back soil pushing on your yard, and the drainage behind it matters as much as the wall.

  • Concrete floor installation

    When you're adding or redoing an interior concrete floor, we prep and pour it level and flat so the finish floor or sealer goes on without fighting dips.

  • Concrete pool decks

    Pool decks take bare feet and splashed water, so we give them a texture that isn't slick and slope them to drain away from the pool and house.

  • Concrete steps construction

    Front steps that have cracked, settled or pulled away from the porch get rebuilt with even risers and a solid footing, since uneven steps trip people.

  • Slab foundation building

    For an addition, a garage or an accessory building, we build the slab on a dug-out, packed base with rebar, steel that keeps any cracks tight.

  • Foundation installation

    When a new structure goes up on your lot, we form and pour the foundation it stands on, after a hard look at the soil and slope.

  • Concrete parking lot building

    For shared lots and the parking at condo and apartment buildings, we replace worn or broken concrete with a base built for steady car traffic.

  • Concrete footings

    Patio covers, walls and steps need footings, the concrete below ground that carries the weight, and we pour them deep enough for the load.

  • Foundation raising

    If part of a slab or house has settled, we find out what's under it first, because lifting it without fixing the cause sets up the next drop.

  • Concrete cutting

    We saw-cut old concrete for a clean edge when only part of a driveway or patio comes out, so the new pour meets the old one square.

Oak Park concrete questions we hear most

Do I need a permit for concrete work in Oak Park, CA?

If your job needs one, it comes from the Ventura County Building and Safety Division, because Oak Park is county land, not a city. The county's guidance says that, generally, buildings and structures need a permit before construction starts, while some small projects are exempt, such as small sheds, flooring and most finish work inside a house. We check with the building office for your address before we start, and if your job needs a permit, I tell you at the estimate and we apply for it before any work begins. If you'd like to ask the county yourself, its Ventura office is 805-654-2771 and its Thousand Oaks office is 805-582-8064.

How do I know if a concrete contractor needs a state license in California?

A contractor needs a California license when the project needs a building permit, uses any additional workers, or when the labor and materials on one or more contracts for the project add up to $1,000 or more. The Contractors State License Board issues those licenses to businesses and individuals who build or alter structures in the state. We're licensed and fully insured.

How much can a contractor ask for as a down payment in California?

No more than $1,000 or 10 percent of the total contract price, whichever is less, under the state licensing board's rules for home improvement work. Any other payments have to be spelled out in the contract and match the work that's done or the materials delivered.

Which building code applies to construction in Oak Park, CA?

The Ventura County Building Code applies, since Oak Park sits in unincorporated Ventura County. The county updates it on a regular cycle to follow the state's building standards, so new work is checked against current rules, not the ones in place when your house went up. On permitted work, the county reviews plans and inspects the work while it's underway to check that it meets those codes.

What affects the cost of a concrete driveway or patio in Oak Park?

The biggest swing is usually the ground, because a sunken slab on a sloped lot needs more digging out, packing and grading than one on flat ground. Size, thickness and finish add to it, and stamped or colored concrete costs more than a plain broom finish. If something has to give, I'd cut the finish before the base, because the base is hidden on day one and it's what decides how long the slab lasts.

How long does a new concrete driveway take to cure before I can drive on it?

Plan on days, not hours, and you'll be walking on it well before you can park on it. Curing is the stretch after the pour when the concrete keeps hardening and gaining strength, and putting a car on it too soon is an easy way to get cracks and a chipped surface. We tell you when it's ready for feet and when it's ready for tires, and I'd rather you wait an extra day than rush it.
