Remodeling Company in San Antonio Heights, CA
San Antonio Heights homeowners call us most often about whole-home renovation that accounts for the foothill terrain, older housing stock, and San Bernardino County permitting that shape every project here. We’re a licensed general contractor managing interior remodels, exterior work, additions, and ADUs under one contract, so you’re not juggling five separate trades. Call (866) 253-5808 to talk through your project and get a straight read on scope and cost.
Why San Antonio Heights Homes Are Different
San Antonio Heights is one of the few remaining unincorporated enclaves in the area, and that changes the construction conversation from day one. Properties sit on large lots, many on septic systems and private wells, and horse-keeping is common enough that remodels often work around barns, arenas, and equestrian access. Permits come through San Bernardino County, not the City of Upland, which means grading plans, drainage reviews, and hillside engineering follow county codes that most tract-home contractors rarely touch.
The housing stock is a mix of mid-century ranch-style homes, custom hillside builds from the 1960s through the 1980s, and scattered newer estate homes. Many properties have detached garages, barns, or accessory structures already on site, so additions and ADUs are a natural fit. The climate also drives material choices: hot, dry summers, Santa Ana wind exposure, and winter frost pockets make us favor fire-resistant siding, Class A roofing assemblies, and drainage details that hold up to clay soils expanding and contracting on slopes.

Our Main San Antonio Heights Services
Two services generate the most calls from San Antonio Heights: full general-contractor oversight for complex hillside projects, and interior remodeling that respects the character of older foothill homes while bringing them up to current code.
General Contractor in San Antonio Heights
A hillside remodel in San Antonio Heights almost always involves structural review, drainage correction, and county permitting that a single-trade contractor cannot manage. As your General Contractor in San Antonio Heights, we run the project from grading to finish, coordinating engineering, subs, material procurement, and inspection scheduling under one accountable contract. That matters here because foundation and retaining-wall issues on clay slopes need to be caught before they affect the interior work.
Home Remodeling in San Antonio Heights
Most mid-century and 1980s homes in San Antonio Heights were built well, but layouts and systems are aging. Our Home Remodeling in San Antonio Heights work focuses on kitchen and bath updates, opening floor plans, replacing windows and doors, and modernizing electrical and plumbing without losing the rural foothill character. We bring a curated set of material brands to every project, from Cambria quartz to James Hardie siding, so you don’t have to settle for the limited catalog a single-trade remodeler would offer.

Home Renovation in San Antonio Heights
Home renovation in San Antonio Heights is rarely a cosmetic exercise. The older ranch-style and hillside homes here carry decades of exposure to Santa Ana winds, freeze-thaw cycles, and slope movement, which means a renovation often peels back layers to reveal structural and drainage work that needs addressing before new finishes go in. We approach every project in this area as a full-envelope renovation – interior systems, exterior shell, and site conditions handled together, rather than patched piece by piece. That’s the only way to make an older foothill home perform like a newer one without surprises six months after you’ve moved back in. It’s also why we structure our work as one Home Renovation contract instead of five separate bids from five specialty trades.

What San Antonio Heights Customers Say
"The foundation survey came back dead on. Everything downstream of that being square is the reason the rest of the build went smoothly."
— Oscar Salazar"Three other companies in Chinatown either didn't pick up or wanted to schedule me for the following week. These guys had someone out the next morning."
— Robert Sullivan"Ground up build. Permits, foundation, framing, all of it, and he ran the schedule tightly enough that the subs were never tripping over each other. Finished within a month of a fourteen month estimate."
— Ramon Reyes
