Remodeling Company in Ontario, CA
Home renovation in Ontario means working on houses built between the 1950s and 1970s, when slab foundations and stucco-over-wood-frame construction were the standard. We handle everything from kitchen guts to full exterior overhauls on these mid-century tract homes, and we know what these houses need: re-roofing, repiping, seismic anchoring, and system upgrades that bring them up to today’s code. Call (855) 382-3257 to talk through your project.
Why Ontario Homes Are Different
Ontario’s housing stock is dominated by single-story stucco tract homes built during the postwar Inland Empire boom. Walk through neighborhoods in the 91761 and 91762 ZIP codes and you’ll see the same pattern repeating: slab-on-grade foundations, low-pitched roofs, and floor plans that made sense in 1965 but feel cramped today. These homes were built fast and cheap, and six decades later they need work that goes deeper than cosmetic updates.
The climate here accelerates that aging. Summer highs over 100°F bake roofing materials until they crack and curl. Santa Ana wind events tear at eaves, fascia, and anything not fully secured. The expansive clay soil under Ontario expands and contracts with moisture changes, which is why we see recurring foundation cracks in slab homes across the city. Add in the warehouse and logistics construction boom along the 60 and 10 freeway corridors, and you have a construction market where older residential work competes with constant commercial build-out. That’s the reality of renovating in Ontario: the houses need more than a fresh coat of paint, and the right contractor has to understand both the housing era and the local conditions.
Styles & brands we work with
Our Main Ontario Services
Most Ontario homeowners call us for two things: full general contracting across multiple scopes, and whole-home remodeling that brings mid-century houses into the present. Here’s how each works here.
General Contractor in Ontario
When Ontario homeowners need one accountable contractor across trades, our general contracting service covers the entire job. A typical Ontario project might combine a roof replacement with new windows and a kitchen remodel, and coordinating that across three separate companies is how projects stall. We run the full scope under one contract and one schedule. Our team is authorized to install GAF and Owens Corning roofing systems, and we pull Ontario permits when the work requires it. General Contractor in Ontario covers how we structure these multi-trade projects.
Home Remodeling in Ontario
Mid-century Ontario homes were built with small kitchens, one bathroom, and no concept of an open floor plan. Remodeling here often means removing walls, relocating plumbing, and reworking layouts that haven’t changed since the Eisenhower administration. We handle the full interior scope: KraftMaid cabinets, Cambria and Caesarstone countertops, Schluter waterproofing systems in showers, and Kohler or Moen fixtures. Everything is spec’d and installed by one team. Home Remodeling in Ontario breaks down what a full interior update looks like on these tract homes.

Home Renovation in Ontario
Home renovation on Ontario’s 1950s-to-1970s tract homes is a different job than remodeling a newer house. These homes were built on slab foundations with original electrical panels, galvanized plumbing, and roofs that are now twenty to thirty years past their lifespan. When we renovate here, we’re often addressing what’s behind the walls before we get to the finishes. Home Renovation covers the full scope we offer, from structural upgrades to cosmetic updates.
Home Renovation Contractors
Signs you need it
Foundation cracks in the slab, original galvanized pipes that clog or leak, and an electrical panel that can’t handle modern appliances are the telltale signs an Ontario home needs a renovation contractor’s full assessment.
What it costs in Ontario
A full home renovation in Ontario runs $14,000 – $45,000 depending on how much of the home is being brought up to current code.
How we do it
We open walls, replace plumbing and wiring where needed, reinforce the structure, then rebuild the finished surfaces with brand-name materials like KraftMaid cabinetry and Schluter waterproofing systems.
Home Renovators
Signs you need it
Rooms that feel dated, layouts that don’t work for how your family lives now, and systems that fail one by one are the signs an Ontario homeowner needs a renovation team that works inside and out.
What it costs in Ontario
Home renovators working on Ontario tract homes typically charge between $9,000 and $45,000 depending on whether the job is a single room or a whole-house update.
How we do it
We start with the structural and systems work, then layer in the visible upgrades: new flooring, updated kitchens and baths, insulation, windows, and finishes that match the home’s era or modernize it.

How long does a home renovation take in Ontario?
A single-room renovation in Ontario takes four to eight weeks depending on permits and what’s behind the walls. Whole-home renovations on 1950s and 1960s tract houses typically run three to six months. Call (855) 382-3257 for a realistic timeline on your specific scope.
Do I need permits for a renovation in Ontario?
Most structural, electrical, plumbing, and addition work in Ontario requires city permits, and we pull them as part of the job. Unpermitted work becomes a problem when you sell, and Ontario buyers are checking. Call (855) 382-3257 and we’ll tell you what your project needs.
