Fast, Reliable Home Remodeling Across Ontario
If you own a home in Ontario built between 1945 and 1980, you probably already suspect what a remodel will turn up: galvanized pipes, a 60-amp panel, and stucco that has baked under the Inland Empire sun for fifty or sixty years. We handle all of it. San Bruno Construction runs full-scope residential remodels across Ontario daily, and we plan for the code upgrades a permit triggers before we ever open a wall. Call (866) 472-1908 for a free estimate, and we’ll give you a written line-item bid on your kitchen, bath, addition, or whole-home remodel.
Why San Bruno Construction Is Ontario’s Preferred Home Remodeling Company
Ontario homeowners call us because we do not flinch at what an older house reveals. A 1958 tract home near Euclid Avenue is going to have galvanized supply lines. A downtown craftsman off Holt Boulevard may be sitting on an abandoned oil tank from the citrus era. We have worked these streets and these houses, and our bids account for the realities of Ontario’s building stock from day one.
Our Ontario customers tend to be people who have gotten burned by low bids that ballooned once demolition started. We write allowances for re-pipes, panel upgrades, and seismic corrections into the contract before you sign. When the inspector flags something, you already know what it costs and why. The surprise is handled in writing, not in a frantic phone call.
Noel Carvalho leads every Ontario project from the first walkthrough to the final inspection. One contractor, every phase, from countertops to rooflines to structural repairs. That is the whole point of hiring a general contractor instead of juggling four specialty trades yourself.

Styles & brands we work with







Home Remodeling Contractor in Ontario
A Home Remodeling Contractor in Ontario has to understand something that a contractor in Irvine or Pasadena never deals with: most of the city’s housing stock was built during the post-WWII boom and the 1960s-70s tract expansion, and it was built to codes that no longer apply. That means every kitchen or bath remodel is partly a modernization project. We handle the full scope, from demolition to drywall to finish carpentry, with licensed trades coordinated under one contract.
Whole-Home and Kitchen Remodels
A full kitchen remodel in Ontario runs $14,000 to $45,000 depending on layout, cabinet lines, and what the walls reveal. We source cabinets from KraftMaid and Wellborn, countertops from Cambria and Silestone, and plumbing fixtures from Kohler, Moen, and Delta, and we can coordinate CertainTeed service in Ontario for roofing or siding needs that come up during a full remodel. You choose from real product options, not whatever is on the truck.
Bath and Addition Work
Bathroom remodels in Ontario typically land between $9,000 and $28,000. Home additions run $45,000 to $130,000, and in Ontario’s mid-century tracts, the structural side often includes shear bracing and flashing corrections before we frame the new space. We pull the permits, we schedule the inspections, and we bring in the licensed electricians and plumbers when the job requires them.
Home Remodeling Companies in Ontario
There are plenty of Home Remodeling companies working in Ontario, but very few of them build their bids around what this city’s houses actually contain. Most specialty trade companies do one thing. San Bruno Construction does all of it: interior remodels, exterior envelope work, hardscaping, and even ADU or prefab installations through brands like Abodu and Plant Prefab. That range matters in Ontario, where a simple room addition can turn into a foundation, drainage, and panel job overnight.
What Separates a General Contractor Here
In Ontario’s warehouse and logistics corridor along the I-10, most construction activity is industrial: distribution centers, cold storage, concrete slabs. Residential remodelers are comparatively scarce, and the ones who quote tract homes without checking for galvanized plumbing or buried oil tanks are not doing you a favor. We price for what we know is there and write allowances for what might be.
Coverage Across Ontario’s ZIPs
We work throughout 91758, 91761, 91762, and 91764, from the older downtown grid to the mid-century tracts east of Euclid and north of the 60. If you are within Ontario city limits, we can get a crew to your house for a walkthrough within a few days of your call.
Trusted Brands We Service in Ontario
We also install and coordinate window and door packages from CWS and ES Windows, plus ECO Window Systems for energy-efficient glazing upgrades that make a real difference in Ontario’s hot, dry summers. Because our suppliers run regular routes through the Inland Empire, lead times for Ontario customers track faster than they would for a small contractor ordering piecemeal. We coordinate the trades so you do not have to.

AfterCommon Home Remodeling Problems We See in Ontario Homes
- Galvanized supply lines failing once walls are open. Post-WWII Ontario tract homes were plumbed with steel pipe that corrodes from the inside. Opening a wall for a kitchen remodel often means the city inspector requires a copper or PEX re-pipe before drywall goes back up.
- 60-amp panels that cannot carry a modern kitchen. A 1958 or 1965 home in Ontario was never designed for a microwave, dishwasher, induction range, and EV charger. Remodeling triggers a service upgrade to 200 amps, and that cost should be in the contract, not discovered mid-project.
- Buried oil tanks and old agricultural piping downtown. Ontario’s citrus and dairy past left things in the ground. Downtown craftsman and Spanish colonial remodels on the city’s older grid sometimes hit abandoned tanks or pipe runs that require removal and soil testing before foundation work can continue.
- Stucco cracking and flashing failures from Santa Ana heat. Ontario’s summers bake exterior stucco and dry out flashing faster than coastal Los Angeles. When we open an exterior wall for an addition, we check what is behind the stucco and correct waterproofing issues before they become interior damage.

FAQs About Home Remodeling in Ontario
Because most Ontario homes built between 1945 and 1975 contain galvanized plumbing, 60-amp electrical panels, and framing that does not meet current seismic or waterproofing codes. Once a wall is open and the city inspector sees it, the upgrade becomes mandatory. We write allowances for exactly these items into the contract before you sign. Call (866) 472-1908 and we will tell you what to expect in your specific house.
We inspect before we bid, then we write a priced allowance for the most likely surprises: copper or PEX re-pipe, 200-amp service upgrade, shear bracing, flashing corrections, and oil tank testing in downtown zones. If something else turns up during demolition, we stop, price it in writing, and get your approval before we continue. No change orders you did not sign off on.
Yes. Ontario’s building department requires permits for any remodel that moves plumbing, changes electrical, alters framing, or adds square footage. We pull all permits, schedule all inspections, and make sure the city signs off on rough-in before drywall goes up. Working unpermitted in Ontario will come back to bite you when you sell, and it will fail any honest home inspection.
Expect the foundation and framing conversation to happen before the design conversation. Ontario’s mid-century tracts often lack shear bracing, and older neighborhoods downtown may sit on soil with drainage issues or buried agricultural infrastructure. We handle the structural corrections as part of the addition scope, not as a surprise line item later.
We use a deposit at contract signing, progress payments tied to inspection milestones, and a final payment at completion and city sign-off. You never pay for the next phase before the last one is inspected and approved. Exact terms are written into the contract, and they apply the same way whether the job is a $14,000 kitchen or a $130,000 addition.
