Remodeling Company in San Antonio Heights, CA
Home renovation in San Antonio Heights means working with hillside lots, older mid-century homes, and San Bernardino County permitting, not a city building department. Elmwood Contractors handles the full scope of a renovation here: interior remodels, exterior envelope work, drainage and slope corrections, and structural upgrades on homes built from the 1950s through the 1970s. If you’re planning a kitchen, bathroom, addition, or whole-home refresh in 91784, call (866) 253-8554 for a free estimate. We name the brands going into your home before the contract is signed.
Why San Antonio Heights Homes Are Different
San Antonio Heights sits on the alluvial fan at the base of the San Gabriel Mountains, north of Upland. The lots climb. Many properties are cut into the hillside, which means the construction scope here rarely stops at the room being renovated. You’re also dealing with retaining walls, pier-and-grade foundations, multi-level decks, and drainage that has to move winter rain off a slope without washing out the neighbor’s yard below.
The housing stock is mostly custom mid-century construction from the 1950s through the 1970s, with scattered estate properties on large lots. That era of building gives us good bones to work with, but it also brings original electrical panels, cast-iron drain lines, single-pane windows, and roof structures that were not designed for today’s fire-resistance standards. Renovation in San Antonio Heights routinely becomes a structural and envelope upgrade, not just a cosmetic one.
Two things define the work here more than anything else. First, the climate: hot, dry summers and the Santa Ana wind corridor put this community in a high-fire-severity foothill zone. Brush clearance, fire-resistant roofing, and ignition-resistant siding are not optional add-ons; they’re what San Bernardino County expects to see on the permit drawings. Second, jurisdiction: San Antonio Heights is unincorporated county land. Permits go through San Bernardino County, not the City of Upland. Out-of-area builders who assume city jurisdiction lose weeks on the front end of a job before anyone swings a hammer.
Styles & brands we work with







Our Main San Antonio Heights Services
Two services get the most calls from San Antonio Heights homeowners: full general contracting for multi-trade projects and whole-home remodeling that refreshes older hillside properties without losing what made them worth buying in the first place.
General Contractor in San Antonio Heights
When a San Antonio Heights project touches more than one trade, someone has to hold the whole plan together. We coordinate the interior and exterior scope under one project plan: framing, electrical, plumbing, roofing, windows, siding, and hardscape, sequenced so the county inspection schedule moves without gaps. On hillside lots, that coordination includes drainage and slope work ahead of the finish trades. One contractor, every trade, with one point of accountability. See General Contractor in San Antonio Heights for the full scope.

Home Remodeling in San Antonio Heights
Remodeling a mid-century San Antonio Heights home usually means opening up compartmented floor plans, replacing original single-pane windows, and bringing kitchens and baths up to current plumbing and electrical code. We match material choices to the house and the fire zone: fiber-cement siding where the original wood is tired, impact-rated windows where Santa Ana winds drive embers, and drainage corrections where the hillside has been moving water toward the foundation. See Home Remodeling in San Antonio Heights.

Home Renovation in San Antonio Heights
Home renovation in San Antonio Heights is, most of the time, renovation plus structural triage. The homes are mid-century, the lots are sloped, and the climate punishes anything that was not built for fire and wind. A kitchen remodel here often surfaces a drainage problem at the foundation, and a bathroom renovation reveals cast-iron drain lines that have reached the end of their life. That’s exactly the kind of multi-trade work we coordinate as a single-source general contractor through our Home Renovation division. We recommend products because they perform on a hillside in a fire zone, not because they’re convenient for us.
Home Renovation Contractors
San Antonio Heights homeowners hire renovation contractors to run the whole job: permits, demo, framing, rough-in, finishes, and the final county inspection. On a hillside property, that scope includes verifying the foundation and drainage before finish materials go in.
Signs you need it
You have a renovation that touches multiple trades, or you’ve heard from one contractor that the work will require permits through San Bernardino County and coordinated inspections.
What it costs in San Antonio Heights
Whole-home renovation work in San Antonio Heights typically starts around $14,000 for a single-room project and runs to $130,000 or more for an addition-sized scope, depending on structural and drainage work.
How we do it
We open the project with a site walk focused on slope, drainage, and existing structure, then produce a fixed-price scope with named brands before the contract is signed.
Home Improvement Contractors
Home improvement work in San Antonio Heights ranges from targeted upgrades, like a new kitchen or primary bath, to envelope improvements that harden the home against fire and wind while updating its look.
Signs you need it
Your home has original mid-century finishes, single-pane windows, or siding and roofing that no longer meet current fire-resistance expectations for the foothill zone.
What it costs in San Antonio Heights
Kitchen remodels run $14,000 to $45,000, bathroom remodels $9,000 to $28,000, and window replacement $4,500 to $15,000, with fire-zone material choices pushing costs toward the upper end.
How we do it
We sequence the job so envelope work, like windows and siding, happens before interior finishes, keeping the home weather-tight through a foothill winter.
What Home Renovation Costs in San Antonio Heights
These are the ranges we quote most often in 91784. The final number depends on site conditions, product choices, and how much structural or drainage work the county requires.

How long does a home renovation take in San Antonio Heights?
Most single-room renovations in San Antonio Heights run 6 to 12 weeks once permits are issued. County plan check and hillside structural review add time on the front end, so we pull permits before demo is scheduled.
Will you handle the San Bernardino County permits?
Yes. We pull permits through San Bernardino County for every San Antonio Heights project that requires them, and we manage the inspection schedule through final sign-off. Call (866) 253-8554 to walk through your scope.
