Remodeling Company in Ontario, CA
Home renovation in Ontario, CA means working with houses built between the 1950s and 1970s, heat that hits triple digits in summer, and a city that has grown from citrus groves into one of the Inland Empire’s busiest logistics hubs. San Bernardino Contractors handles every phase of a residential project here, from kitchen and bathroom remodels to roofing, windows, siding, fencing, and ADU construction. Call (855) 473-5620 for a free estimate on your Ontario home.
Why Ontario Homes Are Different
Ontario’s residential landscape splits into two worlds: the older postwar tract homes built in the 1950s through the 1970s across ZIP codes like 91761, 91762, and 91764, and newer master-planned subdivisions that ring the city’s edges. Those older ranch-style homes were built on slab foundations with 2×4 framing and original single-pane windows. When we open walls in a 1960s Ontario ranch, we often find cast-iron plumbing that has corroded from decades of hard water, and electrical panels that were sized for a house with one television and no central air. The heat is the bigger story. Ontario summers run hot and dry, with Santa Ana wind events in the fall. Concrete cures faster than expected, exterior paint dries before it settles into the substrate, and dust control on any remodel that opens a wall or digs a footing is non-negotiable. Graded lots in newer neighborhoods settle, which means hairline slab cracks we need to evaluate before we tile. The old agricultural and industrial roots show up in the building stock, too. Homes near the warehouse corridor along the 60 and 10 freeways sit on soil that was once irrigated farmland, and some of those lots have compaction issues. An Ontario remodel requires a contractor who knows the difference between a cosmetic crack and a structural one.
Styles & brands we work with
Our Main Ontario Services
Ontario homeowners ask about two things most often: a full general-contractor relationship for projects that touch multiple trades, and a complete home remodel. Here is what each covers in Ontario.
General Contractor in Ontario
Hiring a general contractor in Ontario means one point of accountability for every trade, every permit, and every material decision. We coordinate plumbing, electrical, framing, drywall, HVAC, and finish work so you are not chasing a cabinet shop, a tile sub, and a roofer with three different schedules. Older Ontario ranches often need structural work when walls come down, and we handle load calculations, beam installation, and the city’s permit requirements for structural changes. Whether it is a kitchen gut, an addition, or a full exterior refresh with new siding and windows, one contract covers the whole project. For a deeper look at how this works in Ontario, visit our General Contractor in Ontario page.
Home Remodeling in Ontario
A home remodel in Ontario usually starts with a question about time: how long before the Santa Ana winds hit, or how much heat we will be working through. We plan around that. Ontario homes built in the 1960s and 1970s often have functional layouts that just need to breathe, which means we spend real time on sight lines and traffic flow before we touch a hammer. Kitchen and bath remodels are the most common, but we also handle full interior resets, flooring, lighting, and built-ins. Every project is quoted line by line so you know the cost before we start. See the full scope on our Home Remodeling in Ontario page.

Home Renovation in Ontario
Home renovation in Ontario often means bringing a 1950s or 1960s ranch-style home up to current expectations for open sight lines, modern electrical loads, and energy performance. The heat and wind here punish old construction, and the housing stock sees a steady flow of remodels that correct decades of deferred maintenance. San Bernardino Contractors has served Ontario since 2015, and our Home Renovation work covers everything from single-room refreshes to full-home transformations.
Home Renovation Contractors
Signs you need it
You need a renovation contractor when your Ontario home has multiple small failures that add up: a kitchen layout that fights you, a bathroom with failing grout, single-pane windows that radiate heat, and a floor plan that no longer fits how you live.
What it costs in Ontario
A full home renovation in Ontario typically runs from $45,000 to $130,000 depending on scope, square footage, and whether structural changes are involved.
How we do it
We walk the house with you room by room, mark what stays and what goes, produce a written line-item quote, pull Ontario permits, and sequence the work so you can live in part of the house while we renovate the rest.
Home Renovators
Signs you need it
You need home renovators when your Ontario property has good bones but tired surfaces: worn flooring, dated finishes, inefficient fixtures, and rooms that feel closed off despite the square footage.
What it costs in Ontario
Room-by-room renovation work in Ontario runs from $9,000 for a small bathroom up to $20,000 for a small kitchen, with larger multi-room renovations ranging from $14,000 to $45,000 for a kitchen alone.
How we do it
We stage interior renovations around Ontario’s summer heat, protecting finished surfaces from dust during Santa Ana wind events, and sequence material deliveries so nothing sits in a hot garage warping before install.
Home Improvement Contractors
Signs you need it
You need a home improvement contractor when you are juggling three different specialists for one project and the scheduling alone is eating your weekend.
What it costs in Ontario
Home improvement projects in Ontario range from $800 for a backsplash installation to $45,000 for a complete kitchen remodel with structural changes.
How we do it
One contract covers all trades, one schedule sequences the work, and one phone number reaches the person accountable for every day of the project.
Home Renovation Companies
Signs you need it
You need a full-service renovation company when your Ontario project touches plumbing, electrical, and structure all at once, and a specialty contractor keeps handing off to someone else.
What it costs in Ontario
Full-scope renovation projects in Ontario generally fall between $45,000 and $130,000, with kitchen remodels ranging $14,000 to $45,000 and bathroom remodels ranging $9,000 to $28,000.
How we do it
We assign a project lead who stays with the job from demo to final walkthrough, and every trade is scheduled by our office, not by you.
Renovation Contractors
Signs you need it
When older Ontario homes need permitted structural work, you need renovation contractors who know the city’s plan-check process and how to handle slab-on-grade foundations.
What it costs in Ontario
Renovation contractor labor and management in Ontario typically adds 10 to 20 percent to total project cost, built into the ranges above.
How we do it
We handle structural engineering, beam sizing, permit submittal, and inspection scheduling as part of the renovation scope, so the contractor is accountable for the whole deliverable.

What Ontario Customers Say
"Quality construction and a professional operation. Communication was strongest at the site meetings, and slower by email in between."
— Katie Bennett"Weekly site meeting, every week, with a written summary afterward. I always knew where the money and the schedule stood."
— Javier Herrera"The foundation survey came back dead on. Everything downstream of that being square is the reason the rest of the build went smoothly."
— Bethany Delaney
