Masonry Contractor in Rancho Cucamonga - Repairs and Walls That Suit Your Home
Fieldstone Ontario Concrete and Masonry is a masonry contractor based in Ontario, CA. Across Rancho Cucamonga we repair block walls, chimneys and old brick, and build new walls, walkways and hardscape that suit the house.

Masonry work across Rancho Cucamonga
Rancho Cucamonga grew out of three older communities, Alta Loma, Etiwanda and Cucamonga, and each old town center still has its own feel. A lot of the housing went up during the area's big growth in the 1970s, when families from Los Angeles and Orange County came looking for homes they could afford, so on most streets we're looking at block fences, brick planters and fireplaces that have had decades to settle and wear. It's right next door to Ontario, where we're based, and we work the cities around it too, from Upland and Fontana to Pomona.
That mix shapes the job. Around the older town centers, the work is mostly matching brick and mortar so a repair doesn't stick out, and on the tract streets it's long runs of block wall, where the real question is whether a cracked section needs rebuilding or just fresh mortar.
What we do in Rancho Cucamonga
Plenty of homes here have had decades to settle, so when stair-step cracks show up we find the cause first and repair only what's actually failing.
Loose bricks or a cracked crown, the cap at the top, are common on older brick chimneys here. We rebuild what's failing and leave sound brick alone.
On brick planters and fireplaces from the area's growth years, the mortar often goes sandy first. We grind out only the worn joints and refill them to match.
Near the old town centers, a brick with its face flaking off gets cut out and swapped for a close match, so the wall around it stays put.
If the original driveway on your tract home is cracked and stained, pavers set on a packed base look new and can be lifted and reset in sections later.
Sloped yards and raised planters need walls that drain, so we build with gravel behind the block and weep holes that let trapped water out.
Older homes in this city deserve repairs that blend in, so we match the brick, stone and mortar you already have rather than cover it up.
Want a fireplace in a tract-home family room or out on the patio? We build the firebox and surround in brick or stone that fits your house.
Stone veneer, thin stone set over a wall, dresses up the plain stucco fronts and porch columns common here without the weight of full stone.
Block walls between backyards are everywhere in Rancho Cucamonga, and we fix cracked or leaning runs or build new ones that match the neighbors' side.
Adding a room or garage to an older house here? We lay the block foundation walls on a footing sized for the load, so the new part sits steady.
Many backyards here have room for a grill island, and we build the base in block with a brick, stone or stucco face that matches the house.
Tree roots on older lots can lift a front walk into a trip hazard, so we rebuild it in concrete, pavers or brick, sloped to shed water.
A brick garden wall or a pair of entry pillars can suit an older home here better than plain block, and we tool the joints to match the house.
Where an older garden wall or chimney has river rock or fieldstone, we set new stone so the repair or addition looks like it was always there.
Pointing fills worn mortar joints before they open up, and on a mostly sound wall it's often all you need, so I'll tell you if that's the case.
What Rancho Cucamonga homes need from masonry
I come out to every job myself and stay on site with our crew, so the person who walked your yard is the one making sure the work matches what we said.
Good work left alone
I'd rather repoint a solid wall than tear it out, because replacing sound brick just costs you money.
Repairs that blend in
On older homes we match mortar color and brick size so a patch doesn't stand out from across the street.
A tidy site
Years of working around tenants taught me to keep tools picked up and paths clear, because people live there.
Licensed and insured
We're licensed and insured, and I'm happy to answer any question about it before you sign anything.
Backed by our satisfaction guarantee
If something about the finished work bothers you, tell me, and we'll walk it together and talk it through.
Rancho Cucamonga masonry questions
How do I find out if my masonry project in Rancho Cucamonga needs a permit?
Ask the city's Building & Safety office, because its permit list names solar, reroofs and patio covers, not walls, chimneys or other masonry, so the list alone doesn't settle it. Permits there are applied for online through the city's Online Permit Center. When your job does need city sign off, we take care of the permit and set up the inspections, and for a historic home or a wall near a property line, we check with the city early so nothing surprises you.
Does a masonry contractor need a business license to work in Rancho Cucamonga?
Yes, the city requires a business license before anyone starts doing business within city limits, and it covers everyone working there, contractors included. That license is renewed every year and is separate from the state contractor license, so a contractor working on your house here should have both.
What license should a masonry contractor in California have?
A masonry contractor should hold a state contractor license from the Contractors State License Board, the board that licenses and regulates construction work across California. That's separate from any city business license, so ask about both before you sign. We're licensed and insured, and I'm glad to go over it when I come out to look at your job.
How much of a down payment can a contractor ask for in California?
On a home improvement job, the state contractor board caps the down payment at $1,000 or a percentage of the total contract price, whichever is less, so on a smaller job it comes out lower. After that, each payment has to be spelled out in the contract and tied to work done or materials delivered, and those rules cover every home improvement project, masonry included.
How much does masonry work cost in Rancho Cucamonga?
The price depends on the size of the job, the material and how much has to come out before new work goes in, so I can only give you a real number once I've seen it. Repointing a sound wall costs far less than rebuilding one, natural stone runs more than block, and a tight side yard adds labor. The schedule mostly turns on whether a permit and inspections are needed and how long the mortar or concrete has to cure, and the estimate I write up spells out what I'd do and why.
What causes cracks in an old block wall in Rancho Cucamonga?
Usually it's the footing shifting, water from sprinklers or planters soaking the base, tree roots, or mortar that's simply worn out after a few decades. A hairline crack that follows the mortar is often just age and can be repointed, but a lean or a crack running through the block itself usually means the footing moved. I'll come point right at what's going on and tell you honestly if it can wait.
