Foundation repair
When a crack in your foundation keeps widening or a door starts sticking, we find out what's moving before we patch anything, so the repair actually holds.

Mastercraft Antioch Masonry and Concrete repairs and builds masonry around Bay Point homes. That means fixing cracked brick walls, chimneys and steps, repointing worn mortar, and building new retaining walls, block fences, walkways and paver driveways, with each one set up to drain so it stays put.
Most of the calls I get here start the same way. A wall has a crack that's getting longer, a chimney is dropping mortar onto the roof, or the front walk has heaved enough to trip someone. I come out, figure out why it happened and tell you straight what it needs. Sometimes that's a rebuild, and sometimes it's just repointing a few joints.
Most masonry that fails around a house fails because of water. It sits behind a wall with nowhere to go, or it soaks into old mortar and works it loose over time. So when we repair or build here, we sort out where the water goes first. We do the same work in Pittsburg and Concord, and the cause is usually the same.
When a crack in your foundation keeps widening or a door starts sticking, we find out what's moving before we patch anything, so the repair actually holds.
Loose bricks, a cracked cap on top and mortar washing out of an older chimney all let water into the house. We rebuild what's failed so it sheds rain again.
When the mortar between your bricks has gone sandy or sunk back, we grind out the worn joints and pack in fresh mortar matched to the old color and shape.
A few cracked, flaking or loose bricks don't mean the whole wall has to go. We cut out the damaged ones and set matching brick in their place.
Pavers suit a Bay Point driveway that's cracked beyond patching. We dig out, pack a solid base and set the pavers so single ones can be lifted and reset later.
If your yard slopes toward the house or an old wall is leaning, we build retaining walls with gravel and drain pipe behind them so water can't push them over.
Older brick and stone that's been stained, cracked and patched over the years can be brought back. We clean, repair and repoint so it looks right and sheds water.
Adding a fireplace to a living room or a back patio? We build the firebox, hearth and surround in brick or stone, laid out to suit the space.
Stone veneer, thin stone set over an existing wall, dresses up a plain front, a fireplace or a foundation. We prep the backing so water can drain out behind it.
Block walls make solid fences between yards and along property lines. We set them on a proper footing, reinforce them with steel and grout, and cap them neatly.
For additions, garages and crawlspaces, we lay block foundation walls on a sound footing and keep them plumb and level, so the framing above starts out square.
If you want a grill island or an outdoor counter, we build the base in block, brick or stone, with space planned ahead for the grill and its lines.
When the path to your front door has heaved or cracked into a trip hazard, we tear it out and build a new one in pavers, brick, stone or concrete.
New brick garden walls, planters and front fences, laid level and true, with weep holes or drainage wherever the wall holds back soil so it stays put.
Natural stone walls, steps and borders take patience to fit. We sort and shape each stone so it sits tight, whether it's set in mortar or stacked dry.
When only some joints have cracked or dropped out, pointing them early stops the damage. We fill them with mortar softer than your brick, so the brick faces don't crack.
Send us a few lines about your Bay Point job and we'll reply within one business day, and most of the time it's me getting back to you. I'll come out to your property, look at the work myself and give you a free written estimate that spells out what we'll do and what we won't. There's no pressure to book.
(925) 503-1025Bay Point has no city government, so permits here come from Contra Costa County, not a city hall. The county says almost all projects need a permit, repairs included, and many need planning approval before you can even apply for the building permit. That approval comes first, so on bigger jobs it often sets the start date more than our crew does.
When your job needs a permit, we pull it with the county and line up the inspections. If it isn't clear whether it does, we check with the county before work starts instead of guessing. We're based in Antioch and come out to Bay Point the same way we do to Brentwood, so you get the same crew and the same habits.
What moves the price is how much has to come out before we build, how big the job is, the material you choose and how easily the crew can reach the spot. A job that needs a permit or a drainage plan also adds county review and inspections to the schedule. After I see it, the written estimate spells out exactly what we'll do.
I come out to look at every job myself, and I'm on site with our crew when the work gets done. I started as a helper mixing mortar and hauling block, then opened this business as a masonry contractor in Antioch, CA, in 2023 after learning from masons who'd done it for decades. The person who looked at your wall is the one watching it get built.
I'd rather fix why something failed than cover it up. If a wall cracked because water had nowhere to go, a new face on it won't last, so we fix the drainage too. And if your job turns out smaller than you feared, I'll tell you that. We're licensed and insured, and we stand by one promise, satisfaction guaranteed on every job.
If a wall, chimney or path at your place is cracking, call (925) 503-1025 or send us the details through our form. Tell me what you're seeing and how long it's been going on, and I'll set a time to come out and take a look in person before anyone talks about price.
A few things about Bay Point change how we plan masonry here, from what the county asks for on larger hard surfaces to the hazards it names for the community as a whole.
The county says Bay Point residents are more exposed than most to coastal flooding, sea level rise, landslides, earthquakes and wildfire. That's a statement about the whole community, and your lot may be different. On every estimate I look at how your ground drains and whether it's moving, because a wall or foundation that's fighting water or settling won't hold up for long.
The county requires a drainage plan for some projects, including adding 1,000 square feet or more of new hard surface that sheds water, or grading or clearing more than 10,000 square feet down to bare soil. A large paver driveway can reach that first number. We measure early so you know whether a drainage plan is part of the job before any work starts.
Bay Point is mostly single- and multi-family homes, so a lot of our work sits right on a property line, like a block fence between yards or a brick wall shared by units. When a wall belongs to more than one owner, I'd rather everyone agree on the plan before we start, so the repair doesn't stall halfway over who decides what.
The county says some project types need no building permit, but it still asks owners to check with its staff about other permits that may apply. So we don't assume. If your job looks like it might be one of those, we confirm with the county before we start, rather than find out partway through that something was missed.
Yes, the county requires a building permit for a retaining wall 3 feet or taller. Under that height, we still check with the county before we dig, because other permits can still apply. Either way, we build the wall with gravel and drain pipe behind it, since trapped water is what pushes most retaining walls over.
You apply online through the county's ePermits Center, which takes building, planning and public works applications. The county issues permits to a licensed contractor or to the property owner, and a tenant can get one with the owner's written okay. When we do your job, we pull the permit and set up the inspections for you.
The price comes down to what I find on site, so every Bay Point homeowner gets a free written estimate instead of a guess over the phone. Repair usually costs less than rebuilding, block and pavers usually cost less than natural stone or brick, and tight access for the crew adds labor.
Size and permits set the timeline more than anything else. A few cracked bricks or a short run of pointing is a small job, while a new retaining wall means digging, a footing, drainage and inspections along the way. Mortar and concrete also need time to set before we load or backfill them, and we don't rush that part.
You don't need to do much. Clear a path to the wall, chimney or walk so I can see it up close, and tell me when the crack showed up and whether it's grown, because that says a lot about the cause. If the wall sits on a shared line, it helps to have your neighbor in the loop.
Most cracked brick walls can be repaired if the footing underneath is sound and the wall isn't leaning. If it's leaning or the crack keeps growing, something below is moving, and patching the face won't hold. I'll tell you which one yours is, and if the honest answer is the smaller job, that's what goes on the estimate.
A quick call to (925) 503-1025 or a note through our form lets me look into the permit question for your job before I come out, so the estimate already accounts for it.
