Foundation repair
When the brick or block under a Fullerton house shows stair-step cracks, we open it up, find what moved and rebuild the masonry so the house sits on solid support again.
Optimum Yorba Linda Concrete & Masonry is a masonry contractor based in Yorba Linda. We repair and build brick, block and stone work for Fullerton homeowners, from repointing worn joints to new garden and retaining walls.

Fullerton is a short drive west of our base in Yorba Linda, just past Placentia, and the work here covers a lot of ground. The older neighborhoods have brick chimneys, planters and garden walls that are ready for repointing. The hillier parts of the city tend to call for block and retaining walls on sloped yards. We do the same kind of work in Anaheim, just to the south.
The price of a masonry job here turns on its size and height, the material you choose and how much old brick or block has to come out first. It also depends on whether the wall holds back soil, because that means a deeper footing, steel and drainage. The schedule depends mostly on whether the city needs to review plans and issue a permit, and then on when our crew is free. The estimate I write on site gives you the figure for your own job.
The City of Fullerton handles permits through its Building Division. Its design criteria place structural work in Seismic Design Category D, E or F, and each lot's category comes from the maps. For you, that mostly means we plan a retaining wall or block foundation from the start with the footing and steel the city's review expects.
We check with the city's building office before work begins. If your job needs a permit, we handle the paperwork and inspections, since the city allows no construction until it's issued.
We're licensed and insured. Our own masons and helpers do the work, and I'm on site to check it, because a wall carries the name of whoever built it for years.
A lot of the older brick we see here only needs its joints redone. I'll tell you when repointing will do the job and a full rebuild isn't worth your money.
When the brick or block under a Fullerton house shows stair-step cracks, we open it up, find what moved and rebuild the masonry so the house sits on solid support again.
Older brick chimneys here usually loosen at the top first, where sun and rain hit hardest. We rebuild the cap and loose brick and repoint whatever is still sound.
We grind out crumbling mortar joints to a steady depth and pack in fresh mortar matched to the old color, which closes the gaps that let water into older brick.
Cracked or flaking brick on a planter, step or garden wall gets cut out and replaced with brick close to the original in size and color, so the patch doesn't stand out.
We dig out the old driveway, compact a gravel base and lay the pavers tight inside a solid edge. That keeps them from spreading under cars on the steeper drives some Fullerton homes have.
On sloped yards, we build retaining walls on a footing with steel and drainage behind them, because the soil and water a wall holds back are what push most failed walls over.
When older brick and stone has worn unevenly, we clean it gently, repoint it, replace the worst pieces and match the mortar color, so the wall looks cared for rather than new.
We build masonry fireplaces and outdoor fire features with a firebrick lining and a properly sized flue. We set the hearth and surround in the brick or stone you pick.
We set thin stone facing on stucco house fronts, columns and fireplace walls. It goes over metal mesh and a base coat of mortar, so it stays bonded to the wall behind it.
Property-line and side-yard block walls go up on a poured footing, with steel and grout filling the hollow cores. We can finish the cap and face to match the house.
For additions, garages and raised floors, we lay the block foundation walls that carry the framing. We keep them plumb and level so the carpenters start from a true line.
We build outdoor kitchen islands and bar counters in block, then face them in brick, stone or stucco. We size the openings to the grill and doors you've already chosen.
We lay brick, paver and flagstone walkways on a compacted base with a slight slope to shed water. That keeps the path from heaving or holding puddles by the front door.
New brick garden walls and entry pillars get a footing sized to their height. We finish the mortar joints to match the older brick nearby, so a new wall sits comfortably beside an established house.
We lay natural stone for walls, steps and planter beds, choosing and shaping each piece for a tight fit. That matters most on a slope, where loose stone shifts.
When only a few joints have gone sandy or cracked, pointing those spots with color-matched mortar is often enough. It keeps water from loosening the brick around them.
Send the form and we'll reply within one business day to set a time to come out. The estimate is free and done at your house, and you're under no obligation to go ahead.
I come to your house myself to look at the brick, block or ground and write the estimate. The person who prices your job is the same one who checks the work later.
Our crew sweeps, stacks materials and clears mortar and debris at the end of each workday, because you still have to live at the house while the wall goes up.
That's our promise. I'd rather you judge us by the finished wall, straight, clean and matched to your house, than by anything we say beforehand.
Here are plain answers to the permit, code and registration questions that come up before a masonry job in Fullerton.
Often, yes. The city's Building Division lists retaining walls, fireplaces, patios and fences over 6 feet among the work that generally needs a permit. Repairs such as repointing aren't on that list, but that doesn't settle them either way, so I'll confirm with the city for your job.
Projects submitted now are reviewed under the 2025 California Building Codes, along with amendments the city added for local terrain, climate and geology. If your application went in before the new codes took effect, it can stay under the earlier 2022 codes, as long as the permit is issued before that application expires. We build to whichever set your permit falls under.
Often, yes, if it's a free-standing block wall that doesn't hold back soil, because the city normally reviews those over the counter. That route is for smaller projects that need no more than 30 minutes of plan review. The city can still ask for a fuller review, depending on the scope, the complexity or what's already on the lot.
Yes. The city requires anyone doing business or a trade in Fullerton to hold a business registration certificate before any work begins. For jobs such as construction contracting, the city may ask for proof of a state license before it issues one. Both are fair questions to ask any contractor you're thinking of hiring.
