Remodeling Company in Ontario, CA
Home renovation in Ontario means working with a housing stock that splits right down the middle: mid-century tract homes in the older core and fast-moving tenant-improvement cycles out near the 91761 warehouse corridor. The dry inland heat, Santa Ana winds, and occasional heavy winter rain put real stress on stucco, roofing, and drainage. Square Deal Contractors handles the full scope, from roofline to backyard, so one contractor stays accountable through every phase. Call (866) 623-7205 for a free estimate.
Why Ontario Homes Are Different
Ontario sits in the heart of the Inland Empire logistics belt. Construction here is dominated by warehouse and industrial tilt-up work tied to the 91761 distribution corridor, alongside infill residential and remodel work in the older postwar tracts. That mix of big-box industrial and aging single-family means most Ontario projects are either fast-cycle commercial tenant improvements or careful, surprise-heavy remodels of 1950s and 60s homes. A contractor who only does one type of work misses half the picture.
The older homes near downtown Ontario and along the historic Euclid Avenue corridor frequently have original mid-century stucco, galvanized plumbing, and electrical panels that surface during demolition. You plan for cabinets and end up rewiring. The newer infill subdivisions on the 91764 edges are a different story entirely. Meanwhile, Ontario’s hot, dry summers with Santa Ana wind events drive heavy demand for exterior work, stucco repair, and insulation upgrades. Dust control on job sites matters here more than in coastal cities. When the occasional winter rain hits, flat Inland Empire lots expose drainage and grading failures that were invisible all summer.
Styles & brands we work with
Our Main Ontario Services
Most Ontario homeowners call Square Deal Contractors about two things: full general contracting for multi-trade projects and complete home remodeling where one team manages every phase. Here’s what each involves in Ontario.
General Contractor in Ontario
Acting as your general contractor in Ontario means one accountable partner across structural, exterior, and finish work. Older Euclid Avenue homes often need plumbing and electrical brought up to current code before finish work starts, while newer 91764 builds may need nothing more than cosmetic scope. We manage permits, trade sequencing, and material delivery so you’re not coordinating electricians, plumbers, and tile setters yourself. General Contractor in Ontario covers the full scope.
Home Remodeling in Ontario
Home remodeling in Ontario spans kitchens, bathrooms, additions, and whole-home renovations. The 1950s tract homes in 91762 and 91764 often hide galvanized drain lines and undersized electrical services that change the scope once walls open. We tell you what you’re getting and why at every stage, so there are no surprise invoices. Home Remodeling in Ontario walks through the process in detail.

Home Renovation Contractors
Signs you need it
You’re planning a project that touches multiple trades at once, like a kitchen that spills into a family room plus a new sliding door, or a full interior refresh after years of deferred maintenance.
What it costs in Ontario
Full home renovation in Ontario typically runs $45,000 to $130,000 depending on square footage, home age, and the condition of structural and mechanical systems.
How we do it
We start with a scope walk and a written line-item estimate, then sequence demolition, rough-in, inspections, and finish work so no trade waits on another.
Home Renovation Companies
Signs you need it
You’ve gotten quotes from single-trade subs and realized nobody owns the whole schedule, or a past remodel stalled because materials showed up before the rough-in passed inspection.
What it costs in Ontario
Working with a full-scope renovation company in Ontario generally falls between $45,000 and $130,000 for whole-home scope, less for a contained single-room refresh.
How we do it
Square Deal functions as your single point of accountability, pulling permits, managing vetted trade partners, and keeping the job moving from demolition to final walkthrough.

|---|---|
| Full home renovation | $45,000 – $130,000 |

| Garage conversion | $30,000 – $80,000 |
How long does a home renovation in Ontario take?

Will the price change once renovation work starts in Ontario?
Older Ontario homes can reveal galvanized plumbing or undersized electrical during demolition, and that changes scope. We document every change order in writing with a firm price before proceeding, and call (866) 623-7205 for a transparent estimate.

Ontario pricing moves with the age of the house. A 1960s tract home that needs rewiring, repiping, and stucco patching before finish work will land at the upper end of these ranges, while a newer 91764 build with clean mechanicals stays leaner. Either way, you get a defined scope and a fixed price before we start, no runaround, no surprise invoices.
