Why Castro Valley homeowners call C&M

We'd rather fix a wall once. That means finding the reason it failed, telling you plainly what we see and doing only the work your house actually needs.

  1. The owner sees it through

    I come out to look at your job myself, and I keep checking in while my crew works, so the person who heard your concerns is the one watching how the work goes.

  2. We fix the cause first

    Before we patch a crack, we look for what made it, whether that's water getting in, ground moving underneath or the wrong mortar, so you're paying to stop the problem and not just cover it.

  3. Honest about smaller repairs

    If repointing a few joints or resetting a loose cap will do the job, I'll tell you so, even when a bigger job would mean more work for us.

  4. Estimates written in plain words

    Your estimate lists the work and the materials in plain language, so you know what we plan to do and why before anyone picks up a trowel. Call (510) 264-7156 to set one up.

Masonry services in Castro Valley, CA

C&M Castro Valley Concrete & Masonry is a masonry contractor in Castro Valley with 16 services, covering repairs to older brick, mortar and chimneys along with new walls, paving and stone. Most calls start with something cracked, crumbling or loose, and the aim is a repair that holds up because it deals with what caused the damage. Price mostly comes down to how much work there is, the material, how easy the spot is to reach and whether a cause like poor drainage has to be fixed first. The schedule turns on the size of the job, any permit it needs and getting materials that match, and your written estimate spells out the work and materials for your job.

  • A broad gray paver patio extends along a light-colored house, with a sliding glass door and lawn edging.

    Foundation repair

    Seeing cracks in the brick or block your house sits on? We find out what's moving it, then repair the masonry along with the cause behind it.

  • A tall white-painted brick chimney with a metal cap rises from a dark shingle roof.

    Chimney repair

    Loose bricks, crumbling joints or a cracked crown, the concrete cap on top, let water into a chimney. We repair the brick, mortar and crown before it spreads.

  • A low stone retaining wall with pale capstones borders a raised lawn beside a concrete sidewalk.

    Tuckpointing

    What is tuckpointing? It's raking out worn mortar and packing in fresh, finished to match the old joints, for brick that's solid but losing its mortar.

  • A curved paver walkway follows a swimming pool and stone steps with black railings.

    Brick repair

    Cracked, chipped or loose bricks get cut out and replaced with brick matched for size and color, so the repair blends into the wall around it.

  • Driveway paved with interlocking red, tan, and gray stone pavers beside a flower bed and residential street.

    Driveway pavers

    We lay paver driveways on a dug-out, compacted base so the stones stay level under the car, in patterns and colors that suit your house.

  • Sloped landscaped yard with stone retaining walls, boulders, gravel, and shrubs beside a brick house.

    Retaining wall construction

    We build retaining walls for sloped yards, with drainage behind so water doesn't build up and push the wall out, and give you level ground to use.

  • Tiered rounded-stone retaining walls with flower beds line a landscaped slope beside a pond.

    Masonry restoration

    Is older brick or stone worn all over? Restoration takes on the whole wall or chimney, with new joints, replaced brick and cleaning that suits the old work.

  • Circular stone fire pit surrounded by wooden chairs on a paved backyard patio.

    Fireplace installation

    We build brick and stone fireplaces, from the hearth to the surround, for homeowners adding one to a room or replacing a worn-out old one.

  • Gray house with stone veneer along its lower exterior walls and porch columns, surrounded by lawn and garden beds.

    Stone veneer installation

    Want the look of stone without building a stone wall? We set thin stone veneer over existing walls, columns and chimneys, inside or out.

  • Gray concrete block walls and square pillars with pale stone caps border a tan tiled patio beside a canal.

    Concrete block walls

    Need a sturdy wall along a property line or yard? Our concrete block walls get steel and grout inside where the design calls for them.

  • Curved brick retaining walls border a landscaped lawn beside a large brick house at sunset.

    Foundation block wall installation

    For additions, garages and new structures, we lay block foundation walls on concrete footings so the building above has a solid, level start.

  • Raised stone-paver walkway and patio run along a house, supported by a dark block retaining wall with lights.

    Outdoor kitchen masonry

    Counters, grill surrounds and bar walls for outdoor kitchens, built in block, brick or stone, for a backyard where you want to cook and eat outside.

  • Circular gray stone walkway inset in a red brick-paver patio, with concentric rings of contrasting blocks.

    Walkway construction

    A walkway gets you from driveway to door without mud or tripping, and ours are built in brick, pavers, stone or concrete on a well-packed base.

  • Stone masonry outdoor fireplace stands on a tiled patio beside a wooden pergola and seating.

    Brick wall installation

    We lay new brick garden, entry and boundary walls one level row at a time, with neat tooled joints, for homeowners who love the look of real brick.

  • Stone outdoor fireplace and chimney beside a paved patio, with a built-in stone bench and wooded yard.

    Stone masonry

    Stone masonry is natural stone fitted and set by hand into walls, steps, columns and planters, each piece chosen for where it sits.

  • Red brick pavers form a broad entry walkway and steps beside a brick house and flower pots.

    Brick pointing

    When only a few joints have cracked or dropped out, we point just those with matching mortar, so a small problem on steps or walls stays small.

Our process from first call to final walk-through

It starts with a call or a message, and we get back to you within one business day to set up a time to look at the work.

  1. Call or send a message

  2. We look at it together

    I walk the job with you, show you what I think caused the problem and talk through what your choices are. Then you get a written estimate that spells out the work and the materials, free and with no obligation, so you can think it over and decide when you're ready.

  3. My crew does the work

    Once you say go, we sort out any permit your job needs and get it on the calendar. My crew does the work with me checking in as it goes, and if something turns up once the old mortar or soil is opened, you'll hear about it from me before we go further.

  4. We walk the finished job

    When the work is done, we walk it together. I'll point out what we did and why, and mention anything worth keeping an eye on over the years, so you know your house a little better than you did before we came.

About us

Castro Valley, where we're based

Castro Valley isn't its own city. It's one of Alameda County's unincorporated communities, so the county handles what a city hall would elsewhere. Most people know it by Castro Village on Castro Valley Boulevard, the commercial center of Castro Valley, by Lake Chabot, where you can fish or take a boat out all year, and by the Harry Rowell Rodeo Ranch, which still hosts rodeos.

The eastern hills, where Castro Valley, Crow, Cull and Palomares Creeks begin, give plenty of lots a slope, and around town we see a lot of brick chimneys, garden walls and front steps that have put in long years of service. It's home for us, and the same kinds of brick, block and stone work show up in the cities around it, so we do the same careful work there too.

Cities we serve around Castro Valley

C&M Castro Valley Concrete & Masonry is based in Castro Valley, CA, and works in 12 cities with their own pages here, including Hayward and San Leandro. If you don't see your city listed, just ask, because we work in the cities around it too.

Questions about masonry in Castro Valley

(510) 264-7156
How much does masonry repair cost in Castro Valley?

There's no honest single number, because the cost turns on the size of the repair, the material and how hard the spot is to reach. A chimney needs safe access up high, and old brick can take some hunting to match. Your written estimate gives the figure for your job.

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

In its guidance on rebuilding after a declared disaster, the state contractors board caps the down payment at $1,000 or 10 percent of the total contract price, whichever is less. If you're repairing masonry after a declared disaster, that's worth knowing before you sign anything.

How long does a masonry job take in Castro Valley?

It depends on the size of the job, whether it needs a permit and how long matching brick or stone takes to get. Mortar and concrete also need time to set before they carry weight, and I'll talk timing through with you when I come out.

Does a masonry contractor need a license in Castro Valley?

In California, contractors are licensed by the Contractors State License Board, the state agency that licenses and regulates the construction industry. Because Castro Valley is unincorporated, Alameda County also requires its annual business license for doing business there, even for companies based elsewhere. We're fully licensed and insured.

What does tuckpointing involve on an older brick house?

Tuckpointing means raking out worn mortar back to sound material, packing fresh mortar into the joints and shaping it to match the old lines. We clean and dampen the joints first, so the new mortar bonds to the brick instead of drying out too fast.

Do you guarantee your masonry work?

Our promise is your satisfaction, guaranteed. If something about the finished job doesn't sit right with you, call me at (510) 264-7156 and we'll talk it through.

What kind of mortar should be used on old brick?

Old brick usually needs a softer mortar than modern mixes, because mortar harder than the brick can push cracking and flaking into the brick faces instead of the joints. We match the mortar's strength and color to what's there, so the repair wears in with the wall.

Who issues building permits in Castro Valley?

Alameda County does, because Castro Valley is unincorporated, and building permits run through the Alameda County Permit Portal. Work in a county road, sidewalk or public right-of-way falls under the county's separate encroachment permit. When your job needs a permit, we handle the paperwork and inspections.
