Foundation repair
When a crack shows up in the concrete your house sits on or a corner has dropped, we work out why before repairing the foundation.
Mastercraft Antioch Masonry and Concrete is a masonry contractor working in Oakley, CA. We repair brick, chimneys and foundations, build retaining walls, block walls and paver driveways, and fix the mortar joints that let water in.

Mastercraft Antioch Masonry and Concrete handles brick, block, stone and concrete work across Oakley, from cracked chimneys and leaning yard walls to new retaining walls, paver driveways and walkways. We're a masonry contractor based in Antioch, CA, right next door, so Oakley jobs are close to home for our crew.
A lot of what I see in Oakley is newer tract homes with block walls running between back yards and paver or concrete driveways out front. Those walls lean when the footing was too small or water has nowhere to drain, and driveways settle where the base underneath was thin. When we look at one, we start with why it moved, because patching the crack alone usually means it opens again.
On the older houses and bigger lots, the calls lean more toward brick and stone. We rebuild chimney tops, repoint mortar that's turned to sand and build retaining walls where a yard steps down or a slope needs holding back. Oakley borders Antioch on the west and Brentwood to the south, and we work in both, so getting our crew and materials to your house is easy.
When a crack shows up in the concrete your house sits on or a corner has dropped, we work out why before repairing the foundation.
Loose bricks near the top, a cracked cap or mortar washing out of the joints let rain into the chimney, so we repair it before the damage spreads down.
On older brick homes where the joints have gone soft, we grind out the worn mortar and pack in new mortar matched to the color you already have.
Cracked, chipped or crumbling bricks on a wall, step or planter can usually be cut out and replaced one at a time instead of rebuilding the whole thing.
Pavers suit Oakley driveways because a settled spot can be lifted and reset, and we build the base deep enough to carry cars without sinking.
For yards that step down or slopes that keep sliding onto a patio, we build retaining walls with drain rock and a pipe behind them so water can get out.
When an older brick or stone wall, porch or chimney has years of cracks, stains and bad patches, we bring it back with materials that match the original.
If you want a masonry fireplace inside or a wood-burning one on the patio, we build the firebox, hearth and surround with brick made to take the heat.
Thin stone veneer dresses up a plain stucco wall, porch column or fireplace front, and we set it over a proper backing so water drains out behind it.
Block walls are the usual fence between yards here, and when one leans or cracks we check the footing and the steel inside before deciding on repair or rebuild.
For additions, garages and raised floors, we lay block foundation walls on a poured footing, with steel and grout in the cells where the plans call for it.
Warm evenings make outdoor kitchens popular out here, and we build the block base, counters and stone or brick facing around the grill and storage you pick.
A walkway from the driveway to the door or out to the back gate gets a packed gravel base under it, so it stays level and drains instead of heaving.
New brick garden walls, planters and front-yard walls go on a solid footing, with small openings near the bottom so water trapped behind can get out.
Natural stone suits planters, steps, low walls and fire pits, and we lay it dry or in mortar depending on how tall it is and what it holds back.
When only a few joints are cracked or missing, spot pointing fixes them for less than a full repoint, and I'll tell you if that's all it needs.
Send us a few lines about your Oakley project and we'll get back to you within one business day, and most of the time it's me calling. I'll set a time to come look at it myself, then give you a free written estimate that spells out what we'll do and what we won't. There's no obligation to book.
(925) 503-1025The City of Oakley's Building Division issues building permits here, and the city says most construction projects need one before work starts. On a job that needs a permit, the start date usually waits on the city, more so when your project needs drawn plans, which are sent in and reviewed online. After that, each inspection has to pass before we move on to the next stage.
Before you hire anyone, check two things. A contractor needs a state license from the Contractors State License Board for any job that needs a permit, uses employees, or comes to $1,000 or more in labor and materials, and a bigger job can't be split into small contracts to get under that. The city also runs a business license program that covers companies working in Oakley from outside city limits, like us.
We're licensed and insured, and when a job needs a permit we pull it and set up the inspections, or check with the city first if it's unclear. Price moves with the size of the wall or slab, how deep the footing goes, how much old masonry comes out and how easy it is to get our crew in, and your written estimate puts a number on all of it. We check the local rules the same way in Bay Point and every other city we work in.
I started out mixing mortar and hauling block on a small crew, years before anyone let me lay a brick, and I opened this business in Antioch in 2023. I come out to look at every job myself, and I'm on site with our crew when the work gets done, so the person who wrote your estimate is there when it's built.
I'd rather fix why a wall failed than cover up the crack, and if the honest answer is a smaller job, like pointing a few joints instead of a rebuild, I'll tell you that. Satisfaction guaranteed on every job. Call (925) 503-1025 or use the contact form to set up a visit.
A few things about building in Oakley change how we set footings, reinforce walls and handle fresh mortar. Here's what they are and what we do about each one.
The Delta forms Oakley's northern edge, and on lower lots toward it the ground often stays damp longer than it does on higher ground. Water that sits behind a wall pushes on it and softens the soil under the footing, so we put drain rock and an outlet behind retaining walls and slope the grade away from new work.
The city's adopted codes list a soil bearing pressure of 1,000 pounds per square foot to use when there's no soils report, which is how much weight the ground is assumed to carry. That's a modest number, so footings for walls and foundations usually have to be wider to spread the load. If an engineer's soils report allows more, the design follows the report.
The city's codes page lists Oakley in Seismic Zone D. For block walls, foundation walls and chimneys, that usually means steel bars set into the footing and grout filling the cells around them, so the wall moves as one piece instead of cracking apart in a shake. We build that steel in from the start rather than leave it out to save a little on the job.
Summer afternoons in East County get hot and dry, and mortar or concrete that dries too fast ends up weak and crumbly at the surface. In the hot months we start early, keep fresh joints damp and shaded while they set, and save bigger pours for the cooler part of the day, so the work cures the way it should.
Most construction projects in Oakley need a building permit before work starts, the city says. A few jobs are on its list of exempt work, and the Building Division at 925-625-7005 can tell you whether your project needs plans. Short retaining walls are one of those exceptions, covered in the next answer.
A retaining wall up to 4 feet tall, measured from the bottom of the footing to the top, is on Oakley's exempt list unless it holds up extra weight, like a driveway or slope above it, or another condition on the list applies. Since the buried footing counts, the part you see is shorter. Zoning rules on setbacks and fence heights still apply, so check those with the Planning Division.
In Oakley, a building permit can go only to the property owner, an agent the owner authorizes, or a contractor licensed by the Contractors State License Board. That's one more reason to hire a licensed contractor, and if we're doing your job, we're the ones who apply for it.
On a home improvement job, a California contractor can't ask for or take a down payment of more than $1,000 or 10 percent of the contract price, whichever is less. The state contractors board also says every other payment has to be listed in the contract and tied to work finished or materials delivered, so a big check up front is a warning sign.
I give you a number only after seeing the job, because two walls the same length can cost very different amounts. Natural stone usually costs more than block, a rebuild more than a repair, and a wall that needs drainage, steel and a permit more than one that doesn't. The free written estimate lists each piece.
Small repairs can usually go on our schedule soon after you accept the estimate, while permitted work starts once the city issues the permit. Summer heat and winter rain can also move dates, because mortar and concrete need the right conditions to cure. Before we start, clear a path for wheelbarrows, move cars and patio furniture, and mark any sprinkler lines.
Our phone hours run until 11 PM every day of the week, so call (925) 503-1025 after work or describe your project on the contact form.
