Remodeling Company in Ontario, CA
Home renovation in Ontario, CA spans two very different property types: the mid-century stucco tract homes in ZIPs 91762 and 91764, and the newer master-planned subdivisions along the city’s edges. The older homes run into foundation settling, dated electrical panels, and single-pane windows that bake under Inland Empire sun. The newer homes present their own challenges with builder-grade finishes that age out fast. San Mateo Construction handles both, with one team managing everything from re-roofing to kitchen cabinets. Call (855) 901-7266 when you’re ready to talk through your project and get a free estimate.
Why Ontario Homes Are Different
Ontario sits at the high desert edge of the Inland Empire, where summers regularly run past 100 degrees and Santa Ana winds sweep down through the Cajon Pass. For homeowners that means two things: extreme UV degradation on roofing, stucco, and exterior paint, and periodic wind damage to fences and roofing edges. The dry climate keeps moisture-driven rot low, but heat and sun are the real enemies here. Older central Ontario neighborhoods in 91762 and 91764 are dominated by 1940s to 1970s stucco-on-frame construction on concrete slab foundations. Those slabs crack over decades of thermal movement, and the original windows and electrical systems rarely meet today’s energy codes. On the newer side, communities near 91761 and along the city’s edges were built to modern seismic and energy standards, but often with entry-level finishes that homeowners outgrow within ten to fifteen years. The industrial logistics corridor along the I-10 and around the former airport has also shaped the local construction labor market: crews here routinely shift between warehouse tenant improvements and residential renovation, so the trades moving between those worlds bring commercial-grade concrete and framing skills to Ontario homes.
Styles & brands we work with
Our Main Ontario Services
When Ontario homeowners call us, they’re usually looking at a whole-home renovation or a major remodel with multiple systems involved. Here are the two services we get the most calls about.
General Contractor in Ontario
As a general contractor serving Ontario, we run the entire job: permits, scheduling, subcontractors, material procurement, and final inspections. That matters most on Ontario projects where a re-roof, stucco patch, kitchen remodel, and window replacement may all be in scope at once. One accountable team means no finger-pointing between trades when the stucco around a new window doesn’t seal right or the new roof meets the old fascia. We manage the sequence so demolition isn’t sitting exposed during a Santa Ana event. Read more about how we operate as a General Contractor in Ontario.
Home Remodeling in Ontario
Remodeling in Ontario means working around the realities of older slabs and newer tract construction. In a 1962 ranch in 91762, that often means re-plumbing before new cabinetry goes in and leveling floors before tile installation. In a 2015 home near 91761, it more likely means swapping builder-grade fixtures, counters, and flooring for materials that hold up. Either way, we bring a full spectrum of brand-name materials to the job, from James Hardie siding to Cambria countertops. See how we approach Home Remodeling in Ontario.

Home Renovation in Ontario
Home renovation in Ontario usually starts with the shell: roof, stucco, windows, and slab, because those are the systems that the local heat and wind punish hardest. Once the envelope is sound, interior work proceeds without fear that new finishes will get damaged. A 1955 home in 91762 with original single-pane windows and a worn composition roof needs a different sequence than a 2012 home in 91761 that mostly needs cosmetic updates. San Mateo Construction has served Ontario since 2018, and we plan every Home Renovation around the specific condition of the house, not a generic checklist.
Home Renovation Contractors
Signs you need it
You have multiple systems failing or aging out at once: a roof nearing end of life, windows that leak heat, a kitchen layout that doesn’t function, and a bathroom that hasn’t been touched since the Nixon administration.
What it costs in Ontario
A full home renovation in Ontario typically falls between $45,000 and $130,000 depending on scope, with kitchen and bath work driving the largest portion of that figure.
How we do it
We assess the property, sequence the work from exterior envelope to interior finishes, pull permits, manage every trade, and walk you through material selections from our brand portfolio before final inspections.
Home Improvement Contractors
Signs you need it
Your home needs upgrades in multiple areas but doesn’t require structural changes: new countertops, updated flooring, fresh interior paint, modernized fixtures, and a roof repair rather than a full replacement.
What it costs in Ontario
Home improvement projects in Ontario span a wide range, with individual work like countertop installation at $2,000 to $6,500 and cabinet installation at $4,000 to $13,000.
How we do it
We bundle the smaller scopes into one coordinated job, ordering materials early to avoid supply delays, and schedule trades so your house isn’t torn up for months at a time.

Will the price change once work starts?
We write fixed-price contracts based on a detailed scope, so the number doesn’t move unless you add scope mid-project. If dry rot behind stucco or slab cracks show up during demolition, we document it and price the change order before any work proceeds. Call (855) 901-7266 for a written estimate.
Brands We Service in Ontario
We install and service product lines from across our supplier network, including James Hardie siding, Plant Prefab ADU modules, Boxabl accessory units, and Tuff Shed structures.

FAQs About Remodeling Company in Ontario
Yes. We pull all necessary permits through the City of Ontario’s building department for structural, electrical, plumbing, and mechanical work. Permits and inspections are included in our project scope, and we schedule all city inspections through final sign-off. Call (855) 901-7266 to discuss your project’s permit path.
Most Ontario master-planned communities have architectural review committees with specific rules on exterior colors, fencing materials, and roof types. We coordinate with your HOA from the start, submit the required documentation, and sequence work so exterior changes don’t get flagged mid-project. Call (855) 901-7266 and mention your HOA when you call.
Start timing depends on permit turnaround and material lead times. Ontario city permits for standard remodels usually clear in 2 to 4 weeks. Custom cabinetry and specialty windows can add 4 to 8 weeks of lead time. We book projects in sequence rather than overlapping crews, so you’ll get a firm start date at contract signing. Call (855) 901-7266 to check current scheduling.

What Ontario Customers Say
"Excellent build. Costs came in about six percent over the original contract, driven mostly by material price movement during the build, which he documented each time."
— Brooke Delaney"Weekly site meeting, every week, with a written summary afterward. I always knew where the money and the schedule stood."
— Ramon Vargas"Allowances in the contract were realistic rather than artificially low to make the bid look good."
— Carrie Hayes
