Remodeling Company in Ontario, CA
Home renovation in Ontario means working with 1950s-1970s stucco tract homes on slab foundations, hot inland summers that regularly push past 100°F, and Santa Ana winds that punish anything not built tight. Hampton Contractors has served Ontario since 2016, handling full-scope residential work from the roofline to the back patio under one contract. We carry recognizable brands like Cambria, Kohler, GAF, and James Hardie, so the materials behind your project are names you already know. Call (833) 467-4075 for a free estimate on your Ontario renovation.
Why Ontario Homes Are Different
Ontario sits at the heart of the Inland Empire’s Inland Valley, where the post-WWII citrus-and-dairy town turned into a logistics and warehouse boomtown. That split defines the building stock: the core ZIPs of 91761, 91762, and 91764 are dominated by single-story stucco tract homes from the 1950s through the 1970s, while a newer ring of 1990s-2000s subdivisions surrounds them and big-box warehouses and tilt-up industrial shells line the I-10 and 60 corridors.
For a residential remodeler, the older core is where most of our Ontario work happens. These homes sit on slab foundations over hot, dry shrink-swell clay soil, so hairline stucco fractures and minor foundation movement are routine callbacks. The climate compounds it: Ontario bakes in summer, which drives aggressive stucco and roof-deck heat gain and makes concrete cure fast and crack if it is not handled correctly. Then the Santa Ana winds arrive, carrying dust and debris that stress roofing, caulking, and every exterior seal. A renovation here has to account for that cycle of heat, wind, and soil movement from the first framing inspection to the final coat of paint.
Styles & brands we work with







Our Main Ontario Services
Two services drive most of our Ontario calls: full general contracting for whole-home scopes and comprehensive home remodeling for kitchens, baths, and interior transformations.
General Contractor in Ontario
When an Ontario homeowner is juggling roofing, siding, windows, and an interior remodel, hiring separate trade contractors means coordinating schedules, permits, and finger-pointing when something goes sideways. Our General Contractor in Ontario service puts one accountable team across every layer of the project. We handle the full residential scope from GAF-certified roofing to James Hardie siding to interior finish work, with brand-name materials throughout and one point of contact from the first estimate to the final walkthrough.

Home Remodeling in Ontario
Ontario’s older stucco homes were built for a different era, and a 1960s kitchen or bathroom rarely holds up to how families live now. Our Home Remodeling in Ontario service covers kitchen and bath remodels, whole-home updates, and interior transformations with brands like KraftMaid, Cambria, Kohler, and Moen. We account for the slab foundations and heat-gain realities of these tract homes throughout the design and build, so the finished work holds up through Ontario summers and Santa Ana wind seasons.

Home Renovation in Ontario
Home renovation in Ontario is about bringing 1950s-1970s tract homes up to modern standards while working around slab-on-grade construction, shrink-swell clay soil, and a climate that punishes shortcuts. Whether you are reworking a tired 1960s kitchen in the 91761 core or opening up a floor plan in a 1990s subdivision, the work has to account for the heat, the wind, and the soil from day one. Our Home Renovation team handles the full scope, with one contractor covering interior work, exterior upgrades, and the coordination between them. Here are the renovation jobs Ontario homeowners call us about most.
Home Renovation Contractors
Signs you need it
When your Ontario home has multiple updates needed at once, from a dated kitchen to failing stucco to single-pane windows, a renovation contractor keeps the project moving as one coordinated whole instead of a series of disconnected repairs.
What it costs in Ontario
Home renovation in Ontario spans a wide range depending on scope, but most whole-home renovations fall between $45,000 and $130,000, with kitchens at $14,000 to $45,000 and bathrooms at $9,000 to $28,000.
How we do it
We start with a walkthrough of your Ontario home to map every layer of the project, then sequence the work so structural, mechanical, and finish trades move through without stalling each other.
Home Improvement Contractors
Signs you need it
If your Ontario home needs upgrades across several areas, from countertops to flooring to exterior caulking, a single home improvement contractor keeps the scope, budget, and schedule under one roof.
What it costs in Ontario
Countertop installation runs $2,000 to $6,500, cabinet installation $4,000 to $13,000, and a full kitchen remodel $14,000 to $45,000, so the total depends on how many systems you are upgrading.
How we do it
We scope every improvement that matters to you, order the brand-name materials once, and then run the trades so your Ontario home is not torn apart longer than necessary.
Home Renovation Companies
Signs you need it
When you are weighing multiple bids and want a renovation company with real brand relationships and a documented material portfolio, the difference is in what comes standard: Cambria quartz, Kohler fixtures, GAF roofing, James Hardie siding.

Plan on $45,000 to $130,000 for a whole-home renovation in Ontario, with smaller scopes like a small kitchen remodel at $9,000 to $20,000 and backsplash installation at $800 to $2,500.
How we do it
We bring the brand catalog to your kitchen table, help you pick materials that match your budget and the Ontario climate, and run the project as one accountable contract.

In Ontario, two things push prices higher than surrounding markets: slab-on-grade foundations in the older core mean any plumbing or layout change involves concrete cutting and careful re-pouring, and the heat-and-wind cycle forces us to spec materials that hold up, from UV-stable exterior caulking to properly ventilated roof decks. Every estimate we give is a written, line-item price. No change orders unless you change the scope.
Neighborhoods We Serve in Ontario
We work throughout Ontario’s residential neighborhoods, from the older stucco tracts in the 91761, 91762, and 91764 ZIPs to the newer subdivisions ringing the city and the homes tucked near the industrial corridors. Our crews know the difference between a 1962 slab home near Vintage and a 1999 tract build near the 60.

FAQs About Remodeling Company in Ontario
We typically get to Ontario homes for an estimate within 3 to 5 business days of your call. Large scopes, like whole-home renovations or ADU construction, may take a week to schedule because the walkthrough is more detailed. Call (833) 467-4075 to get on the calendar.
Many Ontario subdivisions, especially the newer 1990s-2000s communities, have HOA design-review rules that govern exterior changes like fencing, siding, and driveway material. We handle the paperwork and submissions for you, and we never start exterior work until the approval is in hand.
Spring and fall are ideal for roofing, stucco, concrete, and fence work in Ontario. Summer heat cures concrete fast enough to cause cracking if not managed, and Santa Ana wind events from September through November can shut down roofing and tilt-up-style work for days at a time. We schedule exterior scopes around those windows and keep you posted on any weather-driven shifts.

What Ontario Customers Say
"Quality construction and a professional operation. Communication was strongest at the site meetings, and slower by email in between."
— Brandon Nguyen"He caught an error in the engineer's drawings before it got framed, which would have been an expensive thing to discover later."
— Lucia Herrera"Allowances in the contract were realistic rather than artificially low to make the bid look good."
