Fast, Reliable Home Remodeling Across San Antonio Heights
Home remodeling in San Antonio Heights runs $14,000 – $45,000 for a kitchen, $9,000 – $28,000 for a bathroom, and $45,000 – $130,000 for a full addition, but three things make pricing here different from a Upland tract-home job: county permits, septic and well setbacks, and steep lot access. We’ve worked these foothill parcels long enough to scope them accurately before we quote. If you’re planning a remodel off Euclid Avenue or up along 24th Street, call (866) 253-5808 and we’ll walk the property with you.
Why Timberline Contractors Is San Antonio Heights’s Preferred Home Remodeling Company
Most remodelers in the 91784 ZIP drive up from the valley floor and treat this community like a suburb of Upland. It isn’t. San Antonio Heights is unincorporated San Bernardino County, which means county grading and drainage review on sloped lots, septic and well setbacks that dictate where walls can go, and long material hauls up narrow foothill roads. We plan for that from the first site visit, so your quote accounts for county submittals and engineered drainage before drywall ever gets scheduled.
Nelson Fung started Timberline Contractors with a simple rule: scope the hardest part of the job first. On an acreage property off Mountain View Avenue, that meant pulling the county record and locating the septic tank and leach field before we drew a single new wall. That setback line reshaped the whole plan. It’s why San Antonio Heights homeowners keep calling us for whole-house work, and why our estimates don’t surprise you six weeks into the project.
From the foundation to the ridge cap, we handle interior and exterior scope under one contract. That matters on a large-lot remodel where the house, the detached garage, and the future ADU all share the same grading and drainage plan.

Whole House Remodel in San Antonio Heights
A Whole House Remodel in San Antonio Heights typically means more than new cabinets and flooring. On a mid-century ranch with a detached shop or barn, it often includes structural repairs, a plumbing and electrical refresh, roof replacement, and sometimes reworking the envelope so the house finally handles Santa Ana wind and summer heat like it should. Expect to budget $45,000 – $130,000 depending on square footage, structural scope, and how much of the site work the county requires.
Our Home Remodeling team sequences this work carefully on foothill parcels. We don’t demo load-bearing walls before the county grading plan clears, and we don’t schedule cabinet installation while a septic tank sits unlocated under the proposed footprint. The sequence is what keeps a whole-house job from becoming six months of surprises.
Site Work Before Framing
On sloped San Antonio Heights lots, the first two weeks of a whole-home remodel often happen outside the building. We establish access for equipment, locate leach fields and wells, and confirm the pad and drainage plan match what the county will approve. This is where cheap bids from down the hill fall apart, because they never carry the cost of engineered grading or a drainage check in their number.
Interior Scope With Exterior Accountability
Because we carry roofing, siding, and hardscaping under the same contract, a whole-house remodel can move from kitchen and baths to exterior envelope work without a second bid process. If your remodel opens up a wall and we find sheathing compromised by years of wind-driven rain, our crew addresses it without a change order authored by a separate roofing subcontractor.
Luxury Home Remodeling in San Antonio Heights
Luxury Home Remodeling in San Antonio Heights isn’t about gold fixtures. It’s about material performance on a rural foothill lot: Cambria quartz that holds up to hard water from private wells, Therma-Tru entry doors that seal against Santa Ana gusts, James Hardie siding that meets wildfire-hardening requirements, and GAF roofing spec’d for intense UV and wind exposure. Budgets on these projects usually start around $60,000 and climb past $130,000 when a home addition or ADU is included.
Our San Antonio Heights clients tend to research brands seriously, which is why we bring the showroom to the project. You’re not picking finishes from a binder of generic options. We walk you through actual material choices: Caesarstone versus Silestone, Wellborn versus KraftMaid cabinetry, Unilock versus Techo-Bloc pavers for the entry drive. One contractor, every phase.
Fixtures and Finishes That Last Here
Well water in the 91784 ZIP runs hard, so we steer clients toward Kohler and Toto repair in San Antonio Heights fixtures with finishes that don’t cloud after three years. Countertops get sealed for the mineral content in local wells, not the city water assumptions a Upland remodeler brings up the hill.
Exterior Materials Selected for Foothill Conditions
A luxury remodel on a large lot should extend past the back door. Paver driveways, retaining walls, and fire-resistant siding are part of the same material conversation. Techo-Bloc and Cambridge Pavers hold up better than poured concrete on clay soils that move with the seasons, and we factor that expansion into the base prep.
Trusted Brands We Service in San Antonio Heights
We maintain relationships with 50-plus manufacturers across cabinetry, countertops, roofing, siding, windows, doors, plumbing, hardscaping, and prefab construction. That means a San Antonio Heights homeowner isn’t stuck with whatever a single-brand contractor pushes. You want GAF or CertainTeed roofing based on wind ratings? We can price both. Cambria or Caesarstone counters? We’ll show you the difference in person. For hardscaping on sloped lots, we regularly install Unilock, Tremron, Techo-Bloc, and Cambridge Pavers, with base prep spec’d for expansive clay soils. Parts and material lead times for 91784 projects get routed through our network, not a distant distribution yard.
Common Home Remodeling Problems We See in San Antonio Heights Homes
- Septic and leach field conflicts. Plans get drawn, then the county flags a proposed addition sitting too close to the existing system. That forces wall relocation, changed rough-ins, and sometimes a new septic design before the first inspection.
- Expansive clay soil stressing foundations and retaining walls. Seasonal moisture swings crack slabs and push walls out of plumb on hillside parcels. A remodel that doesn’t address drainage first is just decorating over a structural problem.
- Santa Ana wind and wildfire exposure. Older homes here have roof decking and siding that don’t meet current hardening standards. We see storm damage and ember intrusion points that a cosmetic remodel never touches.
- Long material hauls and tight equipment access. Narrow foothill roads and shared driveways off Euclid Avenue make staging difficult. A quote that doesn’t plan for delivery and crane access on a steep lot is a quote that changes later.

AfterPricing for Home Remodeling in San Antonio Heights, CA
San Antonio Heights remodel pricing carries line items that a four-bedroom tract home in Upland doesn’t. County permit submittals, engineered grading review, septic and well location, and long hauls up the hill all add real cost before the first stud is cut. Here’s what you can expect, based on our recent work in the 91784 ZIP:
| Project | Typical Range |
|---|---|
| Kitchen Remodel | $14,000 – $45,000 |
| Bathroom Remodel | $9,000 – $28,000 |
| Home Addition | $45,000 – $130,000 |
| ADU Construction | $90,000 – $220,000 |
| Garage Conversion | $30,000 – $80,000 |
| Countertop Installation | $2,000 – $6,500 |
| Cabinet Installation | $4,000 – $13,000 |
| Roof Replacement | $8,000 – $20,000 |
The biggest cost drivers here are site work and county review, not finishes. A flat half-acre lot with an easy-access driveway lands at the low end. A sloped parcel with septic and well conflicts lands at the high end. Call (866) 253-5808 and we’ll scope your specific lot before we quote it. Estimates are free.

FAQs About Home Remodeling in San Antonio Heights
San Antonio Heights is unincorporated, so all building permits are submitted to San Bernardino County, not the City of Upland. On sloped parcels, that county review often includes an engineered grading and drainage check before framing can start. Call (866) 253-5808 if you want us to pull the exact record for your parcel first.
Septic tanks, leach fields, and wells have county-mandated setback distances that dictate where walls, foundations, and additions can go. If plans are drawn without locating those systems, the county will reject or stall the permit. We locate the septic and well before design work begins.
Yes. Large-lot remodels in the 91784 ZIP carry extra cost for long material hauls, equipment access on narrow or unpaved drives, and site protection during staging. A typical acreage remodel runs 10 – 20% higher than an equivalent tract-home job in Upland. Call (866) 253-5808 for a site-specific estimate.
The county reviews an engineered grading plan that shows how water moves across your parcel before and after construction. On steep lots, this usually includes a drainage study and sometimes retaining wall design. It adds time and cost up front, but it prevents foundation failures and washouts later.
Yes, and it’s often smarter to permit them together under one grading and drainage plan. We work with Abodu, Dvele, Mighty Buildings, Boxabl, and Plant Prefab for ADUs, and coordinate barn or shop construction as part of the same site scope. One contractor manages the whole thing.
