Remodeling Company in Ontario, CA
Home renovation in Ontario, CA means working with housing stock that runs from 1960s tract homes to early-1900s craftsman bungalows, under an inland climate that bakes roofs and stucco faster than anything coastal. Most Ontario homeowners call us when a kitchen or bathroom has aged out, when an exterior envelope is failing, or when they need more square footage without leaving a neighborhood they like. San Bruno Construction has served Ontario since 2016, coordinating every trade and material decision under one contract. Call (866) 472-1908 for a free estimate.
Why Ontario Homes Are Different
Ontario sits at the far eastern edge of the LA basin, where summers regularly push past 95°F and Santa Ana winds rip through the I-10 corridor. That heat and wind are why roof replacements dominate our Ontario work: asphalt shingles here crack, curl, and lose granules years earlier than the same roof in Pasadena or Long Beach. The city’s housing stock splits into two very different remodels. The 1960s and 70s tract neighborhoods around the 10 and 15 freeways are mostly wood-frame stucco ranches with original galvanized plumbing and obsolete electrical panels, and those homes need full mechanical upfits before finish work can start. Downtown and the older grid streets hold craftsman and Spanish colonial homes from the early 1900s, where foundation settling, cracked plaster, and hidden knob-and-tube wiring are common. Ontario redevelopment code enforcement is active, so unpermitted work rarely stays hidden. The move that pays off is pulling permits, documenting the work, and inspecting everything to close.
Styles & brands we work with
Our Main Ontario Services
Two types of calls dominate the phone lines from Ontario homeowners: the large, whole-home project that needs a general contractor to coordinate every trade, and the focused remodel of a kitchen, bath, or exterior space.
General Contractor in Ontario
As the General Contractor in Ontario, we run the full renovation as one project with one point of contact. Ontario’s mixed housing stock means a single remodel can hit old plaster one day and post-tension slab issues the next; the contractor who has seen both can sequence the work without stalling. We pull permits through the city, schedule the licensed trades, order materials from brands with local supply routes, and walk the site through every inspection. You get a single contract, a single schedule, and a single person to call when something changes.
Home Remodeling in Ontario
Our Home Remodeling in Ontario work covers kitchens, bathrooms, additions, and the exterior envelope: roofing, windows, siding, and doors. The inland sun punishes Ontario exteriors, so material choice matters more here than it does in the cooler coastal cities. We help homeowners select products that hold up under intense UV and dry heat, from impact-rated windows to reflective roofing systems. Every remodel starts with a detailed scope and a written, line-item estimate, so you can price the job realistically before any crews arrive.

Home Renovation in Ontario
Home renovation in Ontario is a different job than the same remodel closer to the coast. The post-WWII and 1960s-70s housing stock here was built fast with the materials of its era, and sixty or seventy years of inland heat and dry air have taken their toll: original galvanized supply lines, undersized electrical panels, and stucco that needs more than a patch. A smart Ontario renovation sequences the unglamorous work first – the repipe, the panel upgrade, the shear-wall or foundation repair – before finish materials go in. That sequencing is where a full-scope Home Renovation contractor earns the fee, because every trade and inspection has to line up or the job stalls.

Prices in Ontario climb when a remodel uncovers buried oil tanks or old agricultural piping, a remnant of the citrus and dairy land under the city. High water tables and expansive soils in the old agricultural districts also add foundation cost on additions and ADUs. Whatever the scope, we quote fixed, line-item prices before work starts, and we do not change the number once the contract is signed.
