Remodeling Company in Ontario, CA
Home renovation in Ontario means working with two very different houses: the 1950s and 60s ranch homes near the historic downtown grid, and the 2000s-and-newer stucco builds tied to the warehouse boom. We plan every Ontario job around the Santa Ana winds that funnel through the Cajon Pass, because those wind gusts change how we brace walls, flash windows, and tie down roofs. If you’re planning a kitchen, bath, addition, or full-home renovation, call Sycamore Contractors at (877) 265-6284 for a free estimate.
Why Ontario Homes Are Different
Ontario’s post-war housing stock is unusually varied. Many mid-century ranch homes still carry original single-glazed windows, minimal wall insulation, and aging galvanized plumbing. Those houses often need shear-wall and anchor-bolt retrofits before any addition will pass plan check, a direct result of wind-loading requirements most coastal contractors never face. At the same time, thousands of newer stucco tract homes fill the same ZIP codes, and those properties have their own issues: settling slabs, production-grade finishes, and exterior details stressed by dry heat.
The Santa Ana wind season is the single biggest local variable. We regularly see roof flashing pulled loose, fence posts leaning, and stucco hairline cracks that open wider every windy October. Winter rains, when they arrive, expose flat-roof leaks and poor drainage on older builds. Contractors who work across the Inland Empire know Ontario plan check is active and specific about seismic and wind bracing, so we design to that standard from day one rather than treating it as a surprise during permitting.

Our Main Ontario Services
Two services cover most of what Ontario homeowners ask us to manage, and each has its own dedicated page for the full scope and local detail.
General Contractor in Ontario
Acting as your General Contractor in Ontario means one accountable team handles structural work, finish trades, and the permit path that comes with a wind-exposed city. We coordinate plan check submissions with the city, schedule inspections, and keep every trade on one sequence so a mid-century retrofit or new addition doesn’t stall between phases. For a homeowner juggling a full exterior and interior scope, that single point of contact is the difference between a project that finishes and one that drags.
Home Remodeling in Ontario
Our Home Remodeling in Ontario work spans kitchens, bathrooms, and whole-home updates across both older ranch stock and newer tract housing. In Ontario, that often means opening walls on a 1962 ranch and finding no insulation, then adding it before drywall goes back, or re-flashing every window on a 2015 stucco home that never had the details done right. We handle the discovery work as part of the bid, not as a change order surprise.

Home Renovation in Ontario
Home renovation in Ontario is where the city’s split housing personality shows up fastest. A kitchen remodel in a 1958 ranch near the downtown grid usually starts with plumbing and electrical that never met current code, while the same scope in a 2008 infill home is more about replacing builder-grade finishes with materials you actually chose. Both jobs share one Ontario constant: wind and dry heat punish shortcuts, so we specify materials and flashing details that hold through Santa Ana season. As a full-scope Home Renovation contractor, we handle the demolition, the discovery work, and the finish under one contract.

Home Renovators

What Home Renovation Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Home Addition | $45,000 – $130,000 |
How long does a home renovation take in Ontario?
A single-room remodel usually runs six to ten weeks; a whole-home renovation or addition can take four to eight months. Ontario plan check and inspection scheduling adds time, and we build that into the schedule upfront rather than discovering it mid-project.
Will renovation prices change once the work starts?
Not without your written approval. We write fixed-price contracts after a detailed scope and discovery walk, so the number you sign is the number you pay unless you add scope. Call (877) 265-6284 for a line-item estimate.
Brands We Service in Ontario
Our Ontario jobs run on brand-name materials you can research before you commit: Unilock and Techo-Bloc for hardscaping, Cambria and Silestone for countertops, KraftMaid and Wellborn for cabinets. Common lines are stocked locally through our supplier network, which keeps lead times short. See our brands for the full list.

In Ontario, prices climb when wind bracing or shear-wall retrofits enter the permit scope, which happens more often on older ranch homes than on newer stucco builds. We quote fixed prices from a written scope, so you get a real number before we start, not a range that drifts once walls are open.

"Every inspection passed first time. The building department clearly knows him and that made the whole process easier."
— Luis Rodriguez"Framing crew was meticulous and the walls are straight everywhere. Drywall goes on a lot better when the framing is right."
— Colleen Whitaker"He was upfront about a soil issue that added cost early rather than absorbing it and surprising us at the end."
