Masonry Contractor in Castro Valley, CA - Work That Fits Your Slope and Your Brick
Bedrock Hayward Concrete and Masonry is a masonry contractor in Castro Valley, CA. We repair chimneys and old brick, repoint worn mortar, and build retaining walls, walkways and outdoor kitchens on level lots and hillside yards.

Castro Valley, the way we see it on the job
Castro Valley sits just up from Hayward, where we're based, and it reads more like a neighborhood than a city. The shops gather along Castro Valley Boulevard around Castro Village, and nearly everything else is houses. Most of those houses are lived in by the people who own them, and that changes the questions I get. People here plan to stay, so they want to know how the work will hold up long after we've packed the truck, not just how it looks the day we leave.
Streets start out level near the boulevard and climb toward the hills, so one block can hold a flat lot and a steep one. That slope decides how we lay out a wall, a walk or a patio before we pick a single brick or stone.
Services in Castro Valley, CA
Chimney repair
Older brick chimneys here usually fail at the crown and the top courses first. Our chimney repair rebuilds what's loose with mortar that suits the old brick.
Retaining wall construction
Sloped backyards here often need a wall to hold a terrace. We build them with drainage behind, because trapped water is what pushes walls over.
Tuckpointing
Older brick homes in Castro Valley often have mortar joints gone sandy. We rake out the worn mortar and repoint with a mix that suits the old brick.
Walkway construction
Front walks on sloped lots tend to crack and heave where water runs under them. We rebuild them on a packed base pitched to shed water.
Outdoor kitchen masonry
Plenty of calls here are about building out the backyard. We build outdoor kitchens in brick, block or stone, leveled on a solid footing first.
Foundation repair
Houses on sloped lots can settle unevenly, and the first sign is often a stair-step crack in the foundation. We find out why it moved before patching.
What working in Castro Valley means for your job
Castro Valley doesn't have its own city government. It's one of Alameda County's unincorporated communities, so building permits here go through the county, not a city hall. When a job needs a permit, the county's review and inspections set the pace, so I check with them early, and we handle the paperwork and the inspections for you. Before you hire anyone, check two things. Does the contractor hold a state contractor's license, and do they hold the county business license? The county asks for that license from any business working here, even one based somewhere else, like we are in Hayward.
Price here moves with the yard and the old work more than with the material you pick, and the schedule turns mostly on whether the county needs a permit. You get your own figure at the estimate, once I've seen the slope and the access. It's the same work we do down the hill in San Leandro and around Hayward, just with more climbing.
Slopes, runoff and older brick in Castro Valley
Where does the water go when it rains? That's my first question on a sloped lot here. The eastern hills are where creeks like Crow Creek and Cull Creek start, so water runs downhill across yards and collects against walls, steps and foundations that weren't built to take it. We plan the drainage into every wall and walk before we build, with gravel and a clear way out for the water, because a wall that holds water will start to lean sooner or later.
The other thing we see a lot is old brick. Chimneys, garden walls and front steps that have stood for decades usually need repointing more than rebuilding. I'd rather match the mortar to the brick than use a hard modern mix that cracks the face off it.

I come out to look
I come out myself, look the job over and ask what you've noticed, like where water sits after rain or when the crack showed up. You get the estimate right there, and if the work needs an engineer's design, I'll tell you then.
We check the county permit
We check with Alameda County to see what the job at your address needs, and when a permit is required we handle the paperwork and the inspections. On permitted work, the county's review sets the start date, so I'll keep you posted on where it stands.
We prep the site and build
We protect your plants, paving and walls, stage the materials and get the drainage in before the masonry goes up. The work is done by me and our crew, not handed off to someone you haven't met.
We walk the finished job
Before we call it done, I check the work the way a cook tastes a plate before it goes out, and then we walk it with you and clean up. Your satisfaction, guaranteed.
Castro Valley masonry questions, answered
Who handles building permits in Castro Valley, CA?
Alameda County handles them, because Castro Valley is unincorporated and the county serves it in place of a city government. The county's permit portal is where you apply for permits, submit plans, schedule inspections and check a permit's status. I check with the county about your address before we start, and when a permit is required we file it and handle the inspections.
Does a contractor need a county business license to work in Castro Valley?
Yes. Alameda County requires its business license for any business activity in the unincorporated area, even for a contractor based elsewhere or one that already holds another city's license. The county treats it as an annual tax paid each calendar year, and its business license portal has the details, so it's fair to ask anyone you hire whether they have one.
How do I check a masonry contractor's license in California?
Look the contractor up with the Contractors State License Board, the state board that licenses and regulates contractors in California. The board sorts licenses into many classifications, so look at what the license covers as well as whether it exists. We're fully licensed and insured, and I'm happy to give you what you need to look us up.
How much of a down payment can a contractor ask for in California?
In its guidance on rebuilding after a declared disaster, the Contractors State License Board caps the down payment at $1,000, or less when the contract price is small. That figure comes from the board's disaster rebuilding guidance, and it's a good reason to read the payment schedule on any contract before you sign.
What does masonry work cost in Castro Valley?
There's no single number, because here the site drives the cost more than the material does. A tall retaining wall on a steep lot, with drainage and an engineer's design, costs well above a level garden wall. A chimney that only needs repointing costs far less than one rebuilt from the roofline up. Access matters too, since hauling block up a hillside yard by hand takes time, so I give you a figure on site once I've seen it.
What causes retaining walls to lean in sloped Castro Valley yards?
Water trapped behind the wall is the usual cause, because wet soil pushes much harder than dry soil, and a wall with no drain gives that water nowhere to go. A wall built too light or too shallow for the slope makes it worse. We build ours with gravel backfill and a drain behind them, and if the wall needs an engineer's design, I tell you at the estimate.

Call (510) 264-7015 or send the form and ask about the job and its county permit steps while it's still small, since a few loose bricks or one wet corner of the yard is an easier fix than a fallen course or a leaning wall.
