What does brick repair involve in Castro Valley?
Brick repair in Castro Valley usually means repointing, which is raking out the worn mortar between your bricks and packing in fresh mortar, so water stops working its way into the wall. Done with the right mortar, it keeps a joint problem from turning into damage to the brick itself that can't be undone.
Most people call C&M Castro Valley Concrete & Masonry when they find sandy grit on a step or a crack running up a wall and want to know how worried to be. The price comes down to how much of the wall needs work, how deep the joints are worn, whether any bricks have to come out and be replaced, and how easy the wall is to reach, so a few low joints on a garden wall is a very different job from a chimney stack, which is really a chimney repair job. The schedule mostly turns on how big the job is and, when your repair needs a permit, how long that takes, and the written estimate spells out what your wall needs.
How can you tell your brick needs repair?
Mortar crumbling out
If you can scratch the mortar out with a key, or you keep finding sandy grit along the bottom of the wall, the joints have worn out. Left alone, they hold less and let in more water, and the bricks around them start to work loose.
Cracks through the joints
A crack that zigzags up through the mortar or runs straight through bricks usually means something is moving, like settling ground or a tree root close by. Those cracks tend to widen and let water in, and I want to know what's pushing before anyone fills them.
Brick faces flaking off
When the face of a brick flakes, pops off or turns powdery, water is usually soaking into it from a bad joint, a gutter or soil piled against the wall. Once a face is gone it doesn't come back, so catching it early can mean replacing a few bricks instead of a whole section.
How we do brick repair, starting with why it failed
I start by working out why the mortar gave up, whether it's water running off a gutter, a planter against the wall or a crack from movement, because new joints over an old problem just wear out again. Then we choose a mortar mix that suits the age and type of your brick and tell you what's in it, rake the worn mortar out without chewing up the brick edges, pack the new mortar in layers, shape the joints to match the ones around them, and clean the brick face before we pack up.
Brick repair often runs into the work beside it. A brick border that sank along with a tired drive can be reset as part of new driveway pavers, and a garden wall that's failing because of the soil behind it calls for retaining wall construction rather than more mortar.
Repointing the joints
This suits a wall where the bricks are still solid but the mortar between them is crumbling, cracked or missing. It's the usual fix on older garden walls, steps and house walls where the brick itself has plenty of life left.
Replacing damaged bricks
When bricks are cracked through, loose or losing their faces, we cut them out and set new ones as close to yours in color and size as we can find, with fresh mortar around them. It suits spots where water or a hard knock has ruined a few bricks but the wall around them is still sound.

Mending old brick since 2013
I learned masonry patching old brick and building small garden walls, then worked on experienced masons' crews before starting this business in 2013. Repair work on older brick, mortar and chimneys is still what we're best known for, so soft brick and tired joints don't surprise us.
Fully licensed and insured masons
We're fully licensed and insured. On a brick wall that sits against your house or along a neighbor's yard, that coverage matters if anything goes wrong while we're working.
With brick, the mortar you put back decides how well the repair holds up, so it's worth a proper look before anyone starts raking joints. Contact us and I'll come take that look with you.
Brick repair, garden walls and permits in Castro Valley
Castro Valley is unincorporated, so building permits here come from Alameda County, and owners apply and schedule inspections through the county's permit portal. Whether a particular brick repair needs one isn't something I'd guess at, so we check with the county for your address, and when it does, we take care of the paperwork and inspections. If you'd like help with the portal yourself, the county's line is 510-670-5440, or you can email permitbid@acpwa.org. On jobs in cities with their own building office, like Hayward and San Leandro, we check with that city instead.
Around Castro Valley we see plenty of brick planters, front steps and low garden walls on older homes, where water and roots have been working on the joints for years. State rules say a garden wall built just for looks has to be done by a landscaping or C-29 masonry contractor, the class that covers brick, masonry walls and fences along with the cleaning, clear waterproofing and caulking that go with them, so it's fair to ask anyone you're talking to which license they hold.
Questions about brick repair in Castro Valley
Do cracked mortar joints need to be fixed right away?
Not always, because a cavity or veneer wall, which is a brick face with a gap or backing behind it, can handle some extra moisture for a while. An older brick industry guide lists crumbling mortar, joints with holes, hairline cracks and mortar worn back more than 1/4 inch as needing repointing, while a newer note from the same group says cracks may not need repair right away. I'll look at yours and tell you plainly whether it's a now job or a keep-an-eye-on-it job.
What kind of mortar is best for repairing an older brick house?
The new mortar should be equal to or lower in strength than the original, because mortar stronger than the old mix can damage the face of the brick, and that damage can't be repaired. On historic brick, masonry cement is generally not recommended, since it usually has no lime and makes a high-strength mortar. Ask whoever you hire how their new mix compares with what's in your wall now.
How long does repointing last on a brick wall?
Mortar joints typically last more than 25 years, while the bricks themselves can last well over 100, depending on how exposed the wall is and what it's made of. Over the life of a brick house, you should expect to renew the joints rather than the bricks, so repointing is normal upkeep and not a sign the wall was built badly.
Who issues building permits for brick work in Castro Valley?
Alameda County issues building permits for Castro Valley, since it's an unincorporated area. When your repair needs one, we handle the application and inspections with the county, as I covered above.
How much does brick repair cost in Castro Valley?
I can't give you an honest number without seeing the wall, so your price comes from a written estimate after I've looked at it with you. Repointing a few worn joints and replacing a section of cracked bricks are very different jobs, and the estimate lists the work and materials so you can see where the money goes.
How do I make sure a mason won't damage my old brick?
Ask how they plan to get the old mortar out, because that's where most of the harm happens. Power saws and grinders are the most common tools, but on thin joints like most brick walls have, saws almost always break the brick edges, and in unskilled hands power tools can wreck soft historic brick.
Other work that often goes with brick repair
Driveway pavers
Cracked, sunken concrete or brick drives can be replaced with pavers, which sit on a packed base and lift out one at a time for repairs.
Retaining wall construction
If soil behind a garden wall keeps pushing it out of line, a new retaining wall built with a footing and drainage is made to carry that load.
