Remodeling Company in Ontario, CA
Remodeling in Ontario, CA means working with a specific kind of housing stock: mid-century ranch homes, 1970s and 80s track builds, and a growing number of newer developments east of the 15. The inland heat and occasional Santa Ana winds put real stress on materials, so we plan every Ontario project around what actually holds up here. Whether it’s a full home renovation in Ontario or a single-room update, the work starts with a written price and a clear scope. Call (254) 272-5876 to talk through your project and get a free estimate.
Why Ontario Homes Are Different

Ontario sits in the Inland Empire, where summer temperatures regularly cross 100 degrees and dry air pulls moisture out of wood framing, stucco, and caulk faster than coastal climates. That means exterior work here demands materials rated for UV exposure and thermal expansion: a James Hardie siding install or a GAF roof system has to be flashed and sealed to handle real heat cycling, not just rain.
The housing stock splits into three rough groups. Older neighborhoods like the historic downtown core have homes from the 1920s through 1950s, often with lath-and-plaster walls, galvanized plumbing, and electrical panels that need upgrading before any remodel gets past inspection. The broad middle band, built between the 1960s and 1990s, is mostly slab-on-grade construction with standard framing but aging windows and HVAC. Newer developments south of the 60 and east toward the 15 tend to be more code-current but often built fast, so we see issues like poorly flashed windows and undersized insulation. Each type changes the remodel approach, and we price for the condition we find, not the condition we hope for.
Permitting in Ontario runs through the city’s Building Department. Most bathroom and kitchen remodels need a permit when plumbing or electrical moves, and the city enforces its own energy-efficiency requirements on top of California state codes. We pull permits, schedule inspections, and make sure the work passes the first time.
Styles & brands we work with







Our Main Ontario Services
Most Ontario homeowners call us for one of two things: a full general-contractor job that touches multiple rooms or a bathroom that has outlived its layout. Each service has a dedicated Ontario page below with full details and pricing.
General Contractor in Ontario
As a General Contractor in Ontario, we run the whole job: permits, scheduling, subs, materials, and inspections. For Ontario homes, that often means coordinating structural work on older houses where every wall opened reveals something the last remodel left behind. We build a line-item quote so you see exactly what the general-contractor scope costs before we start, and the price on the invoice matches the price you approved. No change orders for work we should have caught in the estimate.

Bathroom Remodeling in Ontario
Bathroom remodeling in Ontario usually means pulling out a fiberglass tub-shower from the 1980s and rebuilding the room around a walk-in shower, new vanity, and waterproofing that actually works. Inland Empire water is hard, and older bathrooms show it in crusted valves and mineral-stained tile. We quote bathroom work with the Schluter waterproofing system specified in writing, so the scope is clear: waterproofing, tile, fixtures, and finish, down to the edge trim. The price includes everything, and we stand behind it with the 365-Day Done Right Promise.

Home Renovation in Ontario
Home renovation in Ontario covers the projects that start as one thing and turn out to touch three rooms. A kitchen remodel that opens into a dated living area. A garage conversion that becomes an ADU. When the job involves structural changes, we bring the full general-contractor process: plans, permits, inspections, and a written price for the whole scope, documented before demolition begins. Background-checked, uniformed crews show up on time, and you get photo updates as the work progresses.
