How Alamo's homes and lots shape a concrete job

Alamo is mostly homes, many of them on larger lots than you'll find in the busier cities nearby, along quiet residential streets that climb toward the hills. On our jobs here we meet established ranch-style houses next to newer, larger rebuilds, and the driveways tend to run long, often with a bend or a grade in them. It's a lot like the hillside work we do in Orinda, where the lot decides more of the plan than the house does.

That's why the ground comes first for us here. A long driveway on a slope moves a good deal of water, and a slab poured on dirt that was only raked level will settle with it, so we dig out, pack the base and set the slab to fall away from your house before we talk about finishes.

Concrete work we do for Alamo homes

What working in Alamo means for your permit and your price

Alamo is unincorporated, so Contra Costa County, not a city, issues building and grading permits there and does the inspections, and the county says almost all projects in its unincorporated area need one. That review usually sets the schedule more than the concrete work does, and it takes longer when a job also needs planning approval, the county's look at what may be built on a lot, which comes first and is often required for a new structure or a change to a building's size or outside. Before you hire anyone, you can check two things: a license from the Contractors State License Board and the county business license covered in the questions below.

We help you work out which offices your job goes through, and we handle the permit paperwork with you as part of the job, so you aren't sorting it out alone. After that, your price mostly turns on the ground, meaning how much soil we dig out and pack, how long and steep the driveway runs, whether old concrete comes out first, how much steel goes in and which finish you pick, and I'll give you your own figure once I've walked the site at the estimate. Alamo's sloped lots look a good deal like what we see in Lafayette and Walnut Creek, and the same careful base work carries over.

  • A retaining wall past a certain height needs a county building permit, so on a terraced Alamo yard we settle the wall's height before we price it.
  • A large new paved area, building on steeper ground, or work near a mapped creek or in a flood hazard area can call for a county drainage plan, so we look at where your water already runs before we lay anything out.
  • If you're not sure the county covers your address, its online map, CCMAP, shows which jurisdiction you're in.
  • We cut control joints, shallow grooves that tell the slab where to crack, as soon as the surface will take the saw, so any crack follows a line we chose.
  • If the budget is tight, I'd suggest a simpler finish before a thinner base, because the base is buried on day one and is the one part you can't fix later without tearing the slab out.

Questions Alamo homeowners ask about concrete work

Do I need a permit for a concrete driveway or patio in Alamo?

Your project may well need one, and the county's permit staff are the people to ask before anything is scheduled. The county's permit information page lists work such as additions, repairs, decks and pools rather than driveways or patios by name, so we ask about your exact job with you. County permits go only to licensed contractors, property owners or their authorized agent, which is part of why we take on that paperwork alongside you.

Does a contractor need a Contra Costa County business license to work in Alamo?

Yes, any contractor doing business in unincorporated Contra Costa, Alamo included, needs a county business license, even if the company is based in another city and already holds that city's license. A business located in an incorporated city, as we are in Lafayette, needs both. The county license is an annual tax of $100 plus $10 per employee, and the applicant has to provide a copy of a current state contractor's license.

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

The state licensing board caps a contractor's down payment at $1,000 or 10 percent of the total contract price, whichever is less. The board says that rule covers all home improvement projects, so a driveway, patio or retaining wall falls under it like any other job.

Will my new concrete driveway crack like the old one?

It can, because concrete shrinks as it hardens, but most of the cracking on older driveways comes from a raked base, missing joints or a rushed pour, and those are the parts we take the most care with. We set rebar, steel bars that hold the slab together if it does crack, pour away from the hottest part of the day so the top doesn't turn weak and dusty, and let the slab cure, the slow hardening that gives concrete its strength, before you use it. You'll be able to walk on it well before you can drive on it, and I'll tell you when it's ready for each.
