Call (833) 382-8544 for a free estimate and we’ll give you a written line-item quote before any work begins.
Ontario sits in a strange spot for construction. We’re 40 miles from the coast, so rot and moisture damage are minimal compared to cities like Long Beach. But the Santa Ana winds that pour through the Cajon Pass hit this city hard, and the summer heat cycles bake everything on the exterior. That combination changes what materials actually hold up here, and it’s something we’ve learned by tearing apart hundreds of Ontario homes over the years.
Why Gold Star Contractors Is Ontario’s Preferred Home Remodeling Company
Ontario homeowners keep calling us back because we don’t guess at material specs. We’ve remodeled enough 1950s and 1960s ranch homes off Euclid Avenue and along the Holt corridor to know what’s behind those stucco walls before we open them. The older Ontario housing stock – single-story ranches on slab foundations – comes with original cast-iron plumbing, aging electrical, and the occasional surprise that a newer tract home on the east side won’t have. We plan for those realities from day one.
Our Home Remodeling team manages every phase under one roof: demolition, framing, rough-in, finishes, and the final walkthrough. No juggling three subcontractors who point fingers at each other when something goes wrong. Noel Carranza runs our projects personally, and he’s the one you’ll talk to when you call. That single point of accountability matters on a project that’s going to cost you $30,000 or more.
As a licensed general contractor, we pull permits in Ontario, schedule inspections, and stand behind the result. We’ve passed inspection on hundreds of residential jobs in this city, from simple bathroom remodels to full additions that required structural engineering.
Materials matter here more than most homeowners realize. Ontario’s dry air won’t rot your wood, but the wind-driven dust and UV load will eat cheap fasteners and warp standard vinyl windows within a few years. We specify stainless steel and hot-dip galvanized hardware, marine-grade finishes on exterior metals, and sealed paver joints, because we’ve seen what happens when someone uses the inland-spec version of a job in this climate. It fails. Quietly, and then expensively.
Styles & brands we work with







Full Home Remodel in Ontario
A Full Home Remodel in Ontario means we gut the interior of your existing house down to the studs and rebuild the living space from the inside out. We see this most often with homeowners in the 91761 and 91762 ZIP codes who bought one of those mid-century ranch homes and want to open up the floor plan without adding square footage. The job typically runs $45,000 – $130,000 depending on how much of the footprint you’re reconfiguring.
Slab Foundation Considerations
Unlike pier-and-beam homes on the coast, most Ontario ranches sit directly on concrete slabs. That means relocating plumbing or adding a bathroom requires cutting into the slab, which adds cost and time. We handle that with a concrete cutting crew who knows how to work around the post-tension cables found in many 1960s-era Ontario foundations. The work gets done right, inspected, and patched cleanly.
Full Interior Rebuilds
We tear out everything: kitchens, baths, flooring, drywall, doors, trim. Then we rebuild with materials you choose from our brand portfolio – Cambria or Caesarstone countertops, Kohler or Moen fixtures, KraftMaid cabinetry. You get the full picture of what each room will look like before we order anything.
Home Remodeling Contractor in Ontario
A Home Remodeling Contractor in Ontario is someone who can handle permits, inspections, and all trades without you acting as project manager. We function that way for every job, from a $9,000 small kitchen refresh to a $130,000 addition. When we serve Ontario, our scope covers the full remodel – structural, plumbing, electrical, HVAC, and finishes – under one contract and one schedule.
Single-Source Accountability
Your home is too important to coordinate five different contractors. We specify the brand, manage the install, and stand behind the result. When a countertop seam fails or a window leaks two years later, there’s no debate about which trade was responsible. One contractor. Every system. No handoff gaps.
Licensed and Insured Work
We’re a state-licensed general contractor, insured and bonded, and every remodel in Ontario gets the permits it requires. The inspectors in this city know our work, and that relationship means fewer delays and fewer surprises at final inspection.
Trusted Brands We Service in Ontario
We maintain active partnerships with 50+ manufacturer brands, and that’s not a marketing line. It means we can walk into an Ontario home and specify Cambria or Caesarstone for the counters, KraftMaid for the cabinets, Kohler or Grohe for the fixtures, and GAF or CertainTeed for the roof. We also work with prefab ADU manufacturers like Abodu and Dvele when a homeowner wants a detached unit in the backyard. Having local stock relationships with these brands means shorter lead times for Ontario clients. Premium materials, professionally installed.

AfterCommon Home Remodeling Problems We See in Ontario Homes
- Corroded fasteners on roofing and fencing. Electro-galvanized or zinc-plated hardware corrodes within 5 – 7 years in Ontario because wind-blown dust acts as an abrasive and the heat cycling accelerates oxidation. We specify stainless or hot-dip galvanized on every exterior connection.
- Warped vinyl window frames. Standard vinyl frames soften and warp when temps top 100°F on Ontario summer afternoons, causing seal failures and drafts. We recommend reinforced frames or impact-rated systems like PGT or CGI for the best long-term performance.
- Eroded paver joints. Polymeric sand without a sealing coat erodes quickly under Santa Ana winds, so joints need re-sanding within two years instead of five. We seal every paver job we install in Ontario.
- Hidden utility surprises in older ranches. Homes built in the 1950s and 1960s along Euclid Avenue and Holt Boulevard often have original cast-iron plumbing and 60-amp electrical panels. Remodeling these houses means budgeting for utility retrofits before you hang drywall.
On a 1962 ranch off Euclid Avenue, we tore off a failing cedar fence whose posts had rotted at the concrete line – not from rain, but from irrigation overspray trapped by non-galvanized brackets. We specified hot-dip galvanized post bases and stainless ring-shank nails. The new fence has survived two Santa Ana events without a single loose picket.
Pricing for Home Remodeling in Ontario, CA
Here’s what we charge in Ontario based on recent projects. These are real ranges, not national averages, and they reflect the labor and material costs in this specific market:
| Project | Typical Range in Ontario |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |

The single biggest cost driver in Ontario is whether your house is on a slab foundation, because relocating plumbing and electrical through concrete adds labor and time. The age of your home matters too: a 1960s ranch will need more hidden retrofit work than a 2010 east-side tract build.

FAQs About Home Remodeling in Ontario
Yes, and here’s why: Ontario’s Santa Ana winds carry fine dust that acts like sandpaper on exposed metal, and the intense heat cycling accelerates corrosion even without salt air. Standard zinc-plated fasteners fail in 5 – 7 years here. Stainless or hot-dip galvanized hardware costs about 10 – 15% more upfront but lasts the life of the roof. Call (833) 382-8544 for an exact material estimate.
A slab foundation means plumbing and electrical lines run through concrete, not a crawl space. Moving a sink, toilet, or adding a bathroom requires cutting into the slab, which typically adds $2,000 – $6,000 to the project. We inspect for post-tension cables before cutting to avoid structural damage.
A standard inland-spec remodel using electro-galvanized fasteners and unsealed paver joints will cost about 10 – 15% less upfront than one built to our Ontario-spec standard. But the cheap version fails within 5 – 7 years on fasteners and 2 years on paver joints, so you’ll pay more in repairs within a decade. We quote the right spec from day one.
Yes. As a licensed general contractor, we pull permits with the City of Ontario, schedule all inspections, and stay on-site through final sign-off. You never have to deal with the building department directly.
We secure all exterior work – roofing, fencing, siding, and windows – before wind events are forecast. Tarps get double-tied, materials get strapped, and open framing gets temporary bracing. We monitor wind warnings during any exterior phase and adjust the schedule to keep your home and materials safe. Call (833) 382-8544 to discuss your project.
