Foundation repair
When a crack shows up in a stem wall or a corner of the slab, we find out what's moving first, because patching over a moving crack just reopens it.
Classic Chino Concrete and Masonry repairs and builds brick, block and stone work for homes in Corona, CA, from cracked block walls and worn mortar joints to new retaining walls, paver driveways and outdoor kitchens.

We're a masonry contractor in Chino, CA, and Corona is close enough that our crew is there often. Near downtown we see brick chimneys, porch steps and planters with mortar wearing out of the joints, while the newer tracts are mostly block walls between yards, paver driveways and backyard builds. We do the same kind of work next door in Eastvale and farther west in West Covina.
The price turns on how much wall or paving there is, what it's built from, how easy it is to reach and, on a repair, how far the damage goes once it's open. The schedule turns on the same things plus any permit and the city's inspections, and the estimate I write at your house gives you your own number. The city's construction standards also cover fire hazard severity zones, which apply to some properties, so we check whether yours is one before we plan. On older houses the job usually starts with finding out why the brick failed, and on newer lots it's usually about the footing and the drainage under the wall.
I come out to Corona, look at the wall or chimney, ask a lot of questions and write the estimate, because the cause of a crack is easier to see in person.
The people at your house are our crew, not a sub we've never met, and I check on the job as it goes so the work matches what we agreed on.
I learned masonry on other masons' crews and started this business in Chino in 2017, and the repair jobs that take some figuring are still the ones we're known for.
When a crack shows up in a stem wall or a corner of the slab, we find out what's moving first, because patching over a moving crack just reopens it.
Older Corona houses often have brick chimneys with cracked tops and washed-out joints, and we rebuild the parts that are failing so water stops getting into the brick.
We grind out worn mortar to a sound depth and pack in new mortar matched to the old, so the joints shed water and the brick isn't stressed.
Cracked, chipped or loose bricks on planters, steps and walls get cut out and replaced with brick that's close in size and color, after we find what cracked them.
We dig out the old driveway, build a compacted base for the weight of your cars and lay pavers that can be lifted and reset if one ever settles.
Where a yard steps down or a slope needs holding back, we build retaining walls with drainage behind them, because trapped water is what usually pushes a wall over.
For older brick and stone that's worn but sound, we clean, repoint and repair it piece by piece so the original masonry keeps its look instead of getting covered over.
We build indoor and outdoor fireplaces in brick or stone, laying out the firebox, the hearth and the flue path before any block goes up so the smoke goes where it should.
We put stone veneer, a thin stone facing, over block walls, columns and house fronts, with a water barrier behind it so moisture has a way out.
Lots of Corona yards are fenced with block walls, so we fix leaning or cracked ones and build new walls on a real footing, with steel and grout inside.
For additions, raised floors and crawl spaces, we lay block foundation walls on footings set to the plans, with steel and grout placed where the design calls for it.
We build the block shell for grills, counters and bars in your backyard, then finish it in stone or brick, leaving room for gas, power and water lines.
We lay walkways in pavers, brick, flagstone or concrete over a packed base with a slight slope, so water runs off instead of pooling by your door.
We build brick garden walls, planters and columns on a footing sized for the wall, and we match brick and mortar to your house when the wall sits near it.
We lay natural stone walls, steps and columns by hand, setting each stone so the weight bears on stone instead of resting on the mortar between them.
When only some joints have cracked or dropped out, we repoint those sections and match the color and shape of the joint so the repair doesn't stand out.
Send the form and we'll reply within one business day to set a time. I'll come out to your house, look at the job and write your estimate, with no obligation to go ahead.
The estimate costs nothing, and it's written at your house, because I'd rather see the cracks, the slope and the old mortar than guess from a phone call.
I'll walk you through what I think is causing the problem and what the fix involves, so you can weigh it against any other estimate you get.
We're licensed and insured, which matters on masonry because most wall, paving and chimney jobs need a state license, as the questions below explain.
Here's what Corona homeowners usually ask us about permits and licenses before a masonry job, answered from what the city and state require.
Building permits in Corona go through the city's Planning & Development department, and its permit line is 951-736-2250. When your job needs one, we apply for it and plan the work around inspections, which the city books Monday through Thursday. If it's not clear whether a wall or chimney job needs a permit, we check with the building office before we start.
Yes. The City of Corona requires a business license for every business operating in the city, in any trade, and that includes businesses whose main address is somewhere else, like ours in Chino. The license renews each year on its anniversary date, so a contractor working in Corona has to keep it current.
In California, building or altering a structure takes a license from the Contractors State License Board when the job needs a permit, uses any hired workers, or totals $1,000 or more in labor and materials. The small-job exemption rose from $500 to $1,000 and applies only with no permit and no hired help, so most wall, chimney or paver jobs need one.
Besides Corona, we work in Chino, where we're based, and the cities linked here. If you're nearby and don't see your city, give us a call and ask.
We're open until 9 PM every day, so call (909) 479-6261 or use the form to ask about your project and any permit it needs.
