Masonry contractor in Ontario, CA - careful repairs and new walls that suit your house

Fieldstone Ontario Concrete and Masonry is a masonry contractor based in Ontario, CA. We repair brick, block, stone and chimneys, repoint old mortar, and build new walls, walkways and paver driveways for homes across the city.

A broad driveway of rectangular gray and taupe pavers leads to the street, with bare soil and yellow guide lines along the edges.

Our masonry work across Ontario

Ontario is where we're based and where I learned this work. Before I started Fieldstone in 2023, I spent years patching steps, chimneys and block fences at rentals all over the city for a property management company. Most calls here still sound like that work: a leaning fence between yards, a chimney dropping mortar, or a front step pulling away from the house. They come mostly from homeowners, plus a few landlords who knew me back then. We do the same work next door in Upland, Montclair and Chino.

The city has older houses with brick chimneys and a lifetime of repairs on them, and newer tracts where the call is more often a new wall, walkway or paver driveway. On the older houses, most of the job is sorting good work from failed work, so the price and the timing usually come down to how much is really broken and whether the city needs to sign off.

What we do for Ontario homes

What Ontario homes need from a mason

You'll get a straight answer about what needs work now and what can wait, because selling you work you don't need doesn't help anybody.

  • Licensed and insured

    We're licensed and insured, and the finished work is backed by our satisfaction guarantee.

  • Sound brick stays put

    Tearing out good brick or mortar just costs you money, so we replace only what's failing.

  • Repairs that match

    We match brick, stone and mortar color to the old work so a repair doesn't stand out.

  • A tidy site around your family

    Years of working around tenants taught me to keep paths clear and clean up as we go, because people live here.

  • I'm there while we work

    I walk your job before we write it up, and I stay on site with our crew while the work gets done.

Ontario masonry questions we hear

Do I need a licensed contractor for masonry work in Ontario, CA?

Usually, yes. California requires a license from the Contractors State License Board for any job that needs a building permit, uses hired workers, or runs $1,000 or more in labor and materials combined. A job is exempt only if it needs no permit, uses no employees and stays under $1,000 in total, and the state doesn't allow a bigger job to be split into smaller contracts to get under that line. We're licensed and insured, so that's settled before I show up.

How do I find out if my masonry project needs a permit in Ontario?

Ask the city's Building Department. It issues permits for building projects in Ontario, reviews the plans and inspects the work so it's built right. You can call them at (909) 395-2023, but the counter closes Tuesdays from 7:30 to 9:00 am and the first Thursday of each month from 8:00 to 10:00 am. When your job needs city sign-off, we take care of the permit and set up the inspections. For historic homes or walls near a property line, we check with the city early so nothing catches you off guard.

What affects the cost of masonry work in Ontario, CA?

The price mostly comes down to how much is really failing, how easy it is to reach, and whether new brick, stone or mortar has to match the old. If your job needs a permit, it pays to keep it moving. The first extension on a plan check or permit is free, but the city charges $150 for each extra residential extension after that. When I walk the job, I write up what I'd do and why, so you can see what's driving your number.

How much can a contractor ask for up front on a home project in California?

Under the state's contractor rules, the down payment can be no more than $1,000 or 10 percent of the contract price, whichever is less. After that, the contract should list each payment and tie it to work completed or materials delivered. Those rules cover all home improvement projects, masonry included.

Does a contractor need a business license to work in Ontario, CA?

Yes. The city requires a business license before a business starts working in Ontario, and contractors based outside the city use the same application as local ones. Contractors may also need to give the city their state license number and workers' comp details, and out-of-city contractors list the job location and the job value.

How do I know if my block fence in Ontario needs repair or replacing?

Most block fences need repair, not replacing, unless a long section is leaning hard or cracked through in several places. Loose caps, sandy mortar and a few broken blocks can usually be fixed in place, and tearing out sound block just costs you money. I'll walk the fence with you, point out what's failing and tell you if any of it can wait.
