Services in Corona, CA
Foundation repair
When a crack climbs a Corona house's brick or block from the footing, something underneath usually moved. Our foundation repair starts with finding out why before we rebuild.
Concrete block walls
Block walls separate many back yards here, and cracked or leaning sections come up often. We repair sections to match or rebuild the run on a new footing.
Brick repair
Older brick homes and walls around the city get chipped faces and loose bricks with age. We swap damaged brick for a match in size, color and texture.
Tuckpointing
Crumbling mortar joints are the call we get most on older brick here. We rake out worn mortar and pack in new, matched to the old color.
Retaining wall construction
Sloped back yards here need a wall to hold soil and make flat space. We build them with drainage behind so water doesn't push them over.
Outdoor kitchen masonry
Homeowners here often ask for a grill island or counter out back. We build them in block, brick or stone so they fit the house.
Corona, CA properties and local conditions
Block walls run along the back and side yards of a lot of Corona houses, and they're the walls we're called about most, because cracked joints, a leaning section or a row of loose cap blocks shows up there first. A crack that steps up through the mortar usually means the footing moved, while a crumbling top row usually comes down to water and age, so I find out which it is before we touch anything. Patching a wall that's still moving only holds for a season, so when the footing is the cause, we fix it or rebuild that run on a new one.
Some properties in Corona fall under the city's construction requirements for fire hazard severity zones. Before we plan a fireplace, an outdoor kitchen or a new wall close to the house, if I'm not sure whether yours is one of them, we ask the city first so the design fits from the start.
Working in Corona: permits, licenses and what moves the price
In Corona, building permits come from the city's Planning and Development department, and whether your wall or repair needs one is the city's call. When it does, the permit and the Building Division's inspections set the pace of the job as much as our crew does, so I plan the work around them. Two things are worth checking on any contractor you're thinking of hiring here: a state contractor's license and a Corona business license. We're licensed and fully insured.
What moves the price is mostly the size of the job and how much of the old work has to come out, which I won't know for sure until the old mortar starts coming out. What moves the schedule is the permit and its inspections, when there is one, and your written estimate puts your own figure and what it covers on paper. We're based in Corona, so jobs here are close to home and I can stop by to check the work as it goes, and we do the same work across the cities around it, from Norco and Eastvale to Jurupa Valley.

Call or send us a message
Reach us at (951) 393-1203 or through the form, and we get back to you the same way you reached us. We set a time for me to come out to your Corona property.
We walk the job together
I come out myself, look at the wall or brick with you and tell you what I see and what I can't know until the old mortar comes out. Then I write the estimate, listing what the work includes, so you know what you're paying for before anything starts.
We handle permits and inspections
If the job needs a permit, we pull it, schedule the inspections and meet the inspector on site. The city books inspections Monday through Thursday, with Friday only for a hardship requested by Wednesday at 5 p.m., so we plan the work around those days.
Our crew does the work
Our crew builds and I check the work as it goes, because a problem is easier to fix before the next row goes on. When it's done, we walk the finished job with you before we pack up.
Frequently asked questions
How do I find out if my masonry project needs a permit in Corona?
Call the city's permit line at 951-736-2250 or start from the city's permits page, and describe the work, its size and where it sits on your lot. The city also runs an online permit and project portal for applicants.
Does a contractor based outside Corona need a Corona business license?
Yes, the City of Corona requires a business license for every business working in the city, including contractors whose main address is somewhere else. Licenses renew every 12 months from the anniversary date, and businesses with gross receipts under $5,000 skip the payment but still have to register and show proof they're exempt.
When does a masonry contractor need a California state license?
A contractor needs a license from the Contractors State License Board whenever the job needs a building permit, uses any hired workers or comes to $1,000 or more in labor and materials. That small-job limit rose from $500 to $1,000 at the start of 2025, and it covers only work with no permit and no hired workers, so a wall or repair with a crew on it calls for a licensed contractor whatever it costs.
What building code does Corona use for masonry work?
Corona follows the 2025 edition of the California Building Standards Code, which the city council adopted in November 2025. That's the code the city's inspectors work from, and it's the one we build to on permitted jobs here.
How much does masonry work cost in Corona?
There's no fair number until I've seen your job, because the price comes from the wall or brick in front of us. Beyond size, the things that move it here are whether the footing needs work, how easy it is to get material in and old block out through a side yard, and how hard it is to match older brick and mortar. A permit and its inspections add some cost when the job needs them, and the written estimate breaks out each part so you can compare.
What is the best way to match new mortar to old brick on a Corona house?
The best way is to match the old mortar's color, texture and hardness together, because mortar harder than the old brick can crack the brick around it. I usually mix a small test batch and let it dry against the wall before we point the whole thing, since wet mortar dries a different shade than it looks in the bucket.
About Corona, CA
On our jobs around Corona, we see two kinds of houses most. Newer neighborhoods have block walls along the back and side yards, often shared with the house next door, and side yards narrow enough that getting material in and out is part of the plan. Closer to the older middle of the city, there's more brick and stone, older mortar, and patches from years past that never quite matched.
Homes in Riverside and Temescal Valley show us much of the same, and either way the house tells us how to work. On newer block we're usually fixing a cause and matching a standard block, while on older brick the slow part is matching the brick and mortar so the repair blends into the wall.
