Concrete contractor in Castro Valley - driveways and patios built for sloped lots

You go through Alameda County, because Castro Valley is one of the county's unincorporated communities and the county serves it in place of a city government. Building permits, inspections and permit status all run through the Alameda County Permit Portal, work in a county road, sidewalk or public right-of-way has its own encroachment permit, and the county's permit resources page is the place to start if you're asking whether a project is exempt. Before work starts, we confirm which office covers your address, and when a permit is needed we take care of the application and the inspections and keep you posted.

Yes, the county requires a business license for any business activity in its unincorporated areas, which include Castro Valley, even when the business is based somewhere else or holds another city's license. The county treats it as an annual tax paid each calendar year, so it's a fair thing to ask any contractor about along with their state license.

Most cracks come from the ground moving under the slab and from concrete shrinking as it dries, and on a hillside lot, water running underneath makes both worse. I won't promise a slab that never cracks, so along with the packed base, we add rebar, steel bars set inside the slab that hold the pieces tight if a crack opens. We also cut control joints, shallow grooves that give the concrete a straight line to crack along, early enough that cracks usually follow them instead of wandering across the middle.

You can walk on it well before you can drive on it, and I'll give you both dates on pour day, because the wait depends on the mix, the thickness and the weather that week. That wait is curing, the stretch when concrete keeps gaining strength, and parking on it early is how edges chip and crack. On warm days we pour early, because concrete that dries too fast in midday heat can end up with a weak, dusty top.

The cost comes down to your driveway's size, its slope and what's there now, so I can't give you an honest number until I've measured it. A plain broom finish, a lightly brushed texture that gives tires and shoes some grip, keeps the price down, while stamping, color, a thicker slab or a short wall at a steep cut raise it, and so does a lot where the truck can't get close. Your written estimate lists each of those as its own line.

In its guidance on rebuilding after a declared disaster, the Contractors State License Board puts the down payment cap at $1,000 or 10 percent of the total contract price, whichever is less. The board is the state agency that licenses and regulates contractors, and we're licensed and fully insured.
