Brick, block and stone work
Masonry contractor services in Corona CA: repairs and new builds
Keystone Corona Masonry and Concrete is a masonry contractor in Corona, CA, and most calls we get start with mortar crumbling out of the joints, a crack through a wall or a yard that needs a wall built. We handle 16 kinds of brick, block, stone and concrete work, from small repairs to new walls. On a repair, the price mostly turns on how much brick and mortar has to come out and how hard the match is, and some of that only shows once the old mortar is out. On new work it's the size, the material and the site. The schedule turns on the same things, plus any permit and inspection the job needs. Your free written estimate spells out what your job includes.
Foundation repair
When your foundation cracks or a corner settles, we find the cause first, then repair the block or concrete so the house sits on solid footing again.
Chimney repair
For brick chimneys with loose bricks, a cracked cap or mortar washing out, we rebuild the damaged rows and repoint the joints in mortar that matches.
Tuckpointing
What is tuckpointing? We grind out worn mortar and lay in fresh mortar with a thin, crisp line, which suits older brick fronts that look tired.
Brick repair
We cut out cracked, chipped or loose bricks and replace them with brick matched for size, color and texture, so the repair sits in with the wall.
Driveway pavers
We lay paver driveways on a packed gravel base, a good choice for homeowners who want a driveway that can be repaired one paver at a time later.
Retaining wall construction
We build block and stone retaining walls that hold back the soil, for sloped yards where you'd like more flat ground you can actually use.
Masonry restoration
For older brick and stone that's worn, stained or badly patched, we clean, repair and repoint it piece by piece so it fits the house again.
Fireplace installation
We build brick and stone fireplaces, starting at the firebox where the fire burns, for homeowners adding one indoors or out on the patio.
Stone veneer installation
What's stone veneer? Thin stone set over an existing wall, so a house front, column or fireplace gets the look of stone without a full stone wall.
Concrete block walls
We build concrete block walls for property lines, side yards and privacy, set on a poured footing and finished in stucco, paint or a rough-faced block.
Foundation block wall installation
For a new addition, garage or raised floor, we lay the block foundation walls the rest of the building sits on, straight and level on the footing.
Outdoor kitchen masonry
We build the block, brick or stone base for an outdoor kitchen, with room for the grill, counters and storage you've planned for your backyard.
Walkway construction
We build walkways in pavers, brick, stone or concrete for homes that need a clear, even path from the driveway to the door or around back.
Brick wall installation
Want a brick wall that looks like it's always been there? We build garden, yard and property walls in brick picked to suit your house.
Stone masonry
We set natural stone for walls, steps, columns and planters, fitting each stone by hand for homeowners who want real stone rather than a look-alike.
Brick pointing
Mortar crumbling out of your brick joints? We rake out the loose mortar and refill each joint in a matching color before water gets in behind it.
How a job goes, from call to walkthrough
You call or send a message
Call (951) 393-1203 or send a message through the form, and we'll get back to you within one business day, by phone or by message, whichever way you reached us. Tell us what you're seeing, a crack, loose brick or a wall you want built, and we'll set a time for me to come out.
I look at it with you and write it up
I come out to your house and look at the job with you. I'll tell you what I can see and what I won't know until the old mortar comes out. Then you get a free written estimate that spells out what the work includes, and you're under no obligation to go ahead.
We do the work and walk it with you
If you go ahead, we take care of any permits the job needs, and our crew gets to work while I check it as it goes. When it's done, we walk the finished job with you before we pack up, so you can point out anything that doesn't sit right.
Why hire us, the way we work
Tell me what's going on with your wall, chimney or walkway through our contact form, or call (951) 393-1203.
Repairs matched to what's already there
We match brick, block and stone for size, color and texture and mix the mortar to look like the old joints, so the fix blends in instead of standing out. That's slower than grabbing whatever's on the shelf, and I think it's worth it.
The person who prices it checks it
I come out to look at every job and write the estimate myself. Our crew does the work and I check it as it goes, so nothing gets lost between what I told you and what gets built.
A written estimate you can compare
Your estimate is free and in writing, and it spells out what the job includes. That way you can set it beside other quotes and see whether they really cover the same work.
Permits and inspections handled for you
When a job needs a permit, we pull it, set up the inspections and meet the inspector on site, so you don't have to deal with the city office yourself. If we're not sure what applies, we ask the city or county office before we start.
Masonry questions from Corona homeowners
How much does masonry repair cost in Corona?
It depends on how much damaged brick and mortar has to come out and how hard the match is, so I price it after seeing the job, not over the phone. A few cracked bricks cost far less than rebuilding a section of wall, and some damage only shows once the old mortar is out. Your free written estimate lists exactly what the work includes.
Does matching old brick cost more than using new brick?
It often does, because finding brick that matches an older wall takes time, and sometimes the mortar needs a few test mixes before the color looks right once it dries. On a small repair that's usually a small part of the price. If matching is what's driving your number up, I'll tell you so on the estimate.
How long does a masonry repair take in Corona?
It depends on the size of the job, how much old mortar or brick has to come out and whether a permit and inspections are involved, so I'll give you a schedule after I've seen it. Mortar and concrete also need time to set before the next step. In Corona, inspections can be booked online for Monday through Thursday, which can decide when the next stage starts.
Does a masonry contractor need a license in Corona, CA?
Yes, in most cases, from both the state and the city. California's Contractors State License Board requires a license when a job needs a building permit, uses any hired workers or totals $1,000 or more in labor and materials, a line that used to be $500. The City of Corona also requires a business license for every business working in the city, even one based somewhere else. We're licensed and fully insured.
Can you tell what's wrong with my brick wall before you open it up?
Often not all of it, because what's behind a crack or under crumbling mortar only shows once we start taking it out. I'll tell you what I can see and what might change once the wall is open. If we find more, I'll show you what we found and talk it through with you before we go on.
Do you guarantee your masonry work in Corona?
Yes, every job we do comes with one promise, your satisfaction, guaranteed. We earn it the slow way, by matching repairs to what's already there and walking the finished job with you before we pack up.
Should I get pavers or a poured concrete driveway in Corona?
If you plan to stay in the house a while, I'd usually lean toward pavers, because a cracked or sunken paver can be lifted and reset instead of cutting out a slab. Poured concrete usually costs less up front and goes in faster, but when it cracks, the repair tends to show. If you're torn, I'll lay out both on your estimate.
Which office handles building permits in Corona, CA?
The City of Corona's Planning & Development department handles building permits, and its permit line is 951-736-2250. City Hall is open Monday through Thursday and closed Fridays, and the city also runs an online permit portal for applicants. When your job needs a permit, we deal with the office for you.
Working in Corona, our home city
Corona is home for us, and most days our crew is working on houses somewhere in the city or just past its edges. The city's past shows at Corona Heritage Park & Museum, with a diorama of Corona's citrus heritage and a reenactment of its old road races. City Park is the oldest park in Corona and sits closest to the middle of town, and the city has a master plan aimed at reviving it.
The Corona Public Library has its own art gallery, and the city's trails plan aims to link local paths to regional trails and Cleveland National Forest. Around town we work on everything from older brick fronts to block walls lining back yards, and we see the same kinds of repairs and new walls in the cities next door. If your house is in Corona, we're probably working nearby already.
