Masonry Contractor in Castro Valley - Brick and Stone Work Built to Suit Your House
Allied Alameda Concrete and Masonry repairs and builds brick, block and stone work for homes in Castro Valley, from repointing old mortar and fixing chimneys to new retaining walls, walkways and paver driveways.

What we do in Castro Valley. Repairs first, then new work.
Foundation repair
When a brick or block foundation has cracked, settled or started to crumble, we find the cause before patching anything.
Chimney repair
Loose bricks, a cracked cap on top or mortar washing out near the roofline usually mean the chimney needs attention soon.
Tuckpointing
We grind out worn mortar joints and refill them in a color and profile that match the brick around them.
Brick repair
If bricks have cracked, flaked on the face or come loose, we replace them with the closest match we can find.
Driveway pavers
A paver driveway on a well-packed base makes sense if an old slab has cracked, since single pavers lift out and reset.
Retaining wall construction
Where a yard slopes, we build retaining walls with drainage behind them, so water doesn't push the wall over time.
Masonry restoration
Older brick and stone that's been patched for years can be brought back with matching mortar, cleaning and careful repair.
Fireplace installation
New brick or stone fireplaces built to suit the room, with the firebox, hearth and surround planned together from the start.
Stone veneer installation
Thin stone facing on a wall or foundation, for when you want the look of stone without building a full stone wall.
Concrete block walls
Block walls for property lines, garden edges or low retaining work, filled and reinforced where the wall needs the extra strength.
Foundation block wall installation
A new block foundation wall for a house or an addition, set on a proper footing and reinforced as the plans require.
Outdoor kitchen masonry
If you're planning a grill station or outdoor kitchen, we build the brick, block or stone base and counters to last outside.
Walkway construction
Brick, stone or paver walkways from the street to your door, set on a base that keeps them level and draining.
Brick wall installation
Garden walls, low front walls and freestanding brick walls, laid in a bond and mortar color that suit the house.
Stone masonry
Natural stone walls, steps and edging, laid by hand so each stone sits firm and the joints read well.
Brick pointing
When mortar joints are shallow or cracked but the brick is sound, pointing fills them in before water gets behind the face.
How we work in Castro Valley. It starts with the county.
Castro Valley's building permits come from Alameda County through its permit portal, so on a job that needs one, the county's review and inspections shape the schedule. Before hiring anyone here, look up their state license with the state licensing board and ask for their county business license.
When your project needs a permit, we handle the application and work with the county through the inspections, and at the estimate I'll tell you what the county may ask for. The price turns on how much masonry is involved, how easy the work is to reach and what we find once old mortar or brick comes out.

(510) 254-3205Good masonry lasts in Castro Valley. Rushed work doesn't.
When mortar is too hard for old brick, the brick takes the stress and its face can crack off, and a wall built without drainage behind it can lean out as water builds up over the years. Repairs done that way usually cost more to undo than to do right.
On a lot in the eastern hills, where several of Castro Valley's creeks start, we look closely at where water runs before planning a wall or walkway. We match mortar to the brick, build drainage in from the start and tell you up front when something can't be known until the work is open.
We work beyond Castro Valley too. Ask about your city.
We're based in Alameda and also work in San Leandro, Ashland and many other cities nearby. If yours isn't listed, call (510) 254-3205 and ask.
Before you hire a mason. Here are plain answers.
The answers below cover permits, licenses and down payments in Castro Valley. If your question isn't here, please call and I'll answer it.
Do I need a permit for masonry work in Castro Valley?
Alameda County makes that call, and its permit resources page has guidance on work exempt from a permit, which is the place to start. Work that reaches into a county road, sidewalk or public right-of-way falls under a separate encroachment permit. At the estimate I'll go over what the county may ask for on your job.
Does a contractor need a county business license to work in Castro Valley?
Yes. Alameda County requires a business license for any business activity in its unincorporated areas, even when the business is based elsewhere or already 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 before you hire.
How large a down payment can a contractor ask for in California?
In its guidance on rebuilding after a declared disaster, the state licensing board caps a down payment at $1,000 or 10 percent of the total contract price, whichever is less. That's the board's statement for disaster rebuilding work, and the board's website is the place to read the details.
Can you match the old brick and mortar on my house?
Usually we can come close, and careful repointing and repair on older brick homes are what we're best known for. We match the mortar's color and hardness to the brick, and when a brick match depends on what's available, I'll tell you that at the estimate rather than promise it.
Who comes out when I call a masonry contractor in Castro Valley?
I come out to look at the job myself and go over it with you on site. Our own small crew of masons does the work, and I check in on site while they're there.
