Foundation repair
We repair cracked and settled block and brick foundations on older houses, and I look at drainage first, because water collecting along the wall is usually what started the cracking.
Optimum Yorba Linda Concrete & Masonry is a masonry contractor based in Yorba Linda, CA, building and repairing block walls, brick, stone, chimneys and walkways for homeowners in Placentia, just next door.

Placentia sits right beside Yorba Linda, so it's one of the closest cities our crew works in, and its houses bring us the same kinds of calls we get at home. The older ranch houses tend to have brick chimneys, planters and low front walls with worn mortar, while the newer tracts are lined with block walls that crack, lean or lose their caps along the property lines. We do the same work in Fullerton, Orange and the other cities around Placentia.
The price of a masonry job here turns on its size, the material you choose, how much old work has to come out first and how easily we can get block and mortar into your yard. The schedule depends mostly on whether the city needs to review the work and on what we find once old brick or a footing is opened up. When I come out, I'll look the job over and write the estimate myself, so you have your own figure rather than a guess.
Before we start anything in Placentia, I check with the city's Building and Safety Division, which oversees private construction there. When a job needs a permit, we handle the paperwork and schedule the inspections, so you aren't left sorting that out between visits from our crew.
Placentia requires every business working in the city to hold an annual business license, and the city lists that number among the items needed to pull a permit, so it's a fair question for any contractor.
We're licensed and insured, and the city asks to see a contractor's state license card and, unless they work alone, proof of workers' compensation before a permit is pulled.
Our own masons and helpers do the work, and I'm on site to check it, so the person who looked at your job is the one making sure it's built right.
We repair cracked and settled block and brick foundations on older houses, and I look at drainage first, because water collecting along the wall is usually what started the cracking.
Older Placentia houses often have brick chimneys with loose crowns and worn joints near the roofline, so we rebuild the damaged courses and replace the cap before water works its way inside.
We rake out worn joints, fill them with mortar tinted to the brick and run a thin contrasting line through the center, so an older brick front looks evenly laid again.
When a few bricks have cracked or their faces are flaking off, we cut them out and set matching brick, so you fix the damage without rebuilding the whole wall.
We dig out the old driveway, compact a proper base and set pavers inside a firm border, because a weak base is what lets pavers sink where the car parks.
On sloped back yards we build retaining walls with drainage gravel and a pipe behind them, because water trapped behind a wall is what usually pushes it out of line.
For older brick and stone that's been stained, cracked and patched over the years, we clean, repoint and replace what's failing, matching the original materials as closely as we can find them.
We build masonry fireplaces for living rooms and back patios, laying the firebrick and flue to the maker's instructions so the fire draws well and the heat stays where it belongs.
We put up stone veneer on house fronts, columns and fireplace surrounds over a proper backing and drainage layer, so moisture behind the stone has a way out instead of loosening it.
Block walls divide many Placentia yards, and we build new ones on a footing sized to the wall's height, with steel and grout in the cells so they stay straight.
We lay block foundation walls for additions, garages and raised floors, keeping every course level and straight up and down, because any error at the bottom shows up in the framing above.
We build outdoor kitchen islands and barbecue counters in block, brick or stone, leaving the openings your gas and electrical trades need, so their work goes in cleanly afterward.
We build brick, stone and paver walkways from the driveway to the door or around the side yard, with a compacted base and a slight slope so rain runs off instead of pooling.
We build brick garden walls, planters and low front-yard walls with solid footings and capped tops, so they keep their lines and shed water for years after we've gone.
We lay natural stone for walls, steps, planters and columns, fitting each piece by hand so the joints stay tight and the finished work looks settled into the yard.
When mortar joints are sandy, recessed or cracked but the brick itself is sound, we repoint just the joints with a mortar matched in color and strength to the old one.
Send the form or call, and we'll reply within one business day to set a time. I'll come out, look at the work and write you a free estimate, with no obligation to go ahead.
I come out myself, because footings, drainage behind a wall and how deep the mortar has worn don't show in a photo, and those decide what the job really needs.
We clean up properly at the end of each day, so your driveway, walkway and yard stay usable while the work is going on.
That's our promise, and on the visit I'd rather show you what the finished joints, caps and faces will look like than make bigger ones.
Here are plain answers to the permit, license and plan questions that come up before a wall, walkway or chimney job in Placentia.
Ask the city's building office, because that's the office that decides whether a wall needs a permit. When one is needed, the building division reviews the plans once planning and zoning clearance is in place, and the permit application can be signed by you as the owner, a licensed contractor or your authorized agent.
The city's list of work that needs no building permit includes walks and driveways no more than 30 inches above the ground and not built over a basement or a room below. Any electrical or plumbing work that goes with them, such as path lights, still needs its own permit unless the city exempts it.
Yes, for most jobs. The state requires a license for anyone who contracts work on a project that needs a building permit, uses employee labor, or takes on work worth $1,000 or more in labor and materials combined. Only a small job with no permit, no employees, under $1,000 in all and no claim of being licensed is left out.
Plans the city accepts into review on or after January 1, 2026, have to meet the 2025 California Building Code. If you had drawings made for a wall or an addition before then, it's worth having them checked against the current code before they go in, because older plans may need changes.
