Fast, Reliable General Contractor Across Oak Hills
General contractor work in Oak Hills usually lands between $14,000 and $45,000 for a full kitchen remodel, $9,000 – $28,000 for a bathroom, and $45,000 – $130,000 for a home addition. Those are written ranges, not ballparks. Penhallow Remodeling puts the price in writing before any work starts, and our crews know Oak Hills well enough to warn you about the two things that catch outside contractors off guard: San Bernardino County permitting and caliche hardpan under almost every lot. Call (936) 259-2607 and we’ll give you a real number.
Why Penhallow Remodeling Is Oak Hills’s Preferred General Contractor Company
We work in Oak Hills every week, and we learned the area the hard way through years of footing digs, county inspections, and remodels in 1990s single-story homes along Mesquite Road and up toward Rancho Oak Hills. Homeowners here don’t have the patience for a contractor who shows up late, and neither do we. Every technician who walks onto your property is background-checked and in uniform. You know exactly who is opening your gate.
Trevor Nash runs our crew with a rule that sounds old-fashioned: say the price before the work. Show up in the window we gave. Leave the place cleaner than we found it. We operate under General Contractor standards set by the Kingswell family of companies, which means the 365-Day Done Right Promise applies to every project we touch in Oak Hills. If something fails inside a year, we come back and fix it at no charge. That’s in writing.
Our dispatch and scheduling is coordinated from the Inland Empire office, but the crews serving Oak Hills live and work here in the High Desert. We schedule around county inspection timelines, not around a city building department that doesn’t exist here. That local knowledge saves you time.
General Contractor Services in Oak Hills
General contractor services in Oak Hills cover the full job: permits, demolition, framing, plumbing and electrical rough-in, finishes, and final inspection sign-off. A licensed GC coordinates every trade so you’re not calling four different subs when a shower pan leaks or a cabinet pull comes off. In Oak Hills specifically, that coordination matters more because everything routes through San Bernardino County Building and Safety. Miss one county requirement and the whole job stalls. We handle the paperwork so you don’t have to.
Kitchen and Bath Remodels
The most common job we quote in Oak Hills is a kitchen or bathroom remodel in a home built between 1988 and 2006. Those houses are solid, but the builder-grade oak cabinets, cultured marble counters, and original plumbing fixtures are reaching the end of their life. A full kitchen remodel in Oak Hills runs $14,000 – $45,000 depending on cabinet line, countertop material, and whether you’re moving a sink or range. A bathroom remodel runs $9,000 – $28,000. We install KraftMaid and Wellborn cabinetry, Cambria and Silestone quartz, and Kohler and Moen fixtures because those brands carry warranties that stack on top of ours.

Additions, ADUs, and Garage Conversions
Oak Hills’s large-lot horse properties – often one to two and a half acres – make accessory dwelling units and detached workshops more common here than in most Southern California communities. A garage conversion in Oak Hills runs $30,000 – $80,000. A new ADU runs $90,000 – $220,000. Those are wide ranges because grading, foundation work, and county agricultural overlays change the scope on almost every lot. Before we quote, we walk the property and dig a test hole or two. Caliche doesn’t show up on a county parcel map.

Construction Company in Oak Hills
A construction company in Oak Hills has to understand High Desert soil, wind-load requirements, and freeze-thaw cycles that a lower-elevation builder never thinks about. Oak Hills sits at roughly 3,000 – 3,400 feet. Winter nights dip below freezing, and daily temperature swings of 40 – 50°F are normal. Concrete cures differently here. Framing fastening schedules change because the county enforces Exposure Category C or D wind-load standards in many zones. We build to those standards from the first day, not as a change order after the inspector flags it.
Concrete, Flatwork, and Foundation Scope
If your project touches the ground – a patio, a driveway, a footing for a new wall – the caliche hardpan under Oak Hills will be part of the conversation. Standard auger bits break on that calcium carbonate crust. We bring pneumatic hammers and rock-breaking equipment when the test dig shows caliche, and we price it into the written quote up front. A concrete driveway installation here runs $4,500 – $12,000. A paver driveway runs $7,000 – $18,000. You’ll know the number before we break ground.
Full-Scope Remodeling and Replacement
When you’re replacing multiple systems at once – windows, siding, roof, and interior finishes – one contractor should hold the whole schedule. Window replacement in Oak Hills runs $4,500 – $15,000, and in a high-wind corridor the flashing and fastening details matter more than the glass package. We’re a General Contractor in Oak Hills that carries the full scope so you get one written price, one arrival window, and one warranty covering the entire job.
Trusted Brands We Service in Oak Hills
We don’t install products we can’t stand behind, because our 365-Day Done Right Promise rides on every component. In Oak Hills kitchens we routinely install Cambria and Silestone quartz countertops, KraftMaid and Wellborn cabinetry, and Kohler, Moen, and Blanco fixtures. Cambria quartz carries its own lifetime warranty alongside ours. That’s two layers of protection on the same countertop. We stock common replacement parts locally in the High Desert, which means a failed cabinet hinge or a scratched faucet finish gets addressed fast – usually without waiting on a freight shipment from a distribution center.
Common General Contractor Problems We See in Oak Hills Homes
- Unpermitted work from previous remodels. We regularly open up walls in Oak Hills homes and find electrical or plumbing that was never inspected by San Bernardino County. Homeowners only discover it when they try to sell or refinance. We fix it, pull the right permits, and get the inspection sign-off.
- Builder-grade finishes failing early at elevation. Freeze-thaw cycling at 3,000+ feet destroys cheap cabinet boxes, lightweight subflooring, and flatwork faster than homeowners expect. What worked for five years at sea level cracks and separates in three years here.
- Caliche hardpan turning simple jobs into change orders. A fence post or a deck footing that should take an hour takes half a day when the auger hits caliche. Contractors who don’t know Oak Hills price it as if the soil were soft loam. We test first and price the rock-breaking into the original written quote.
- HOAs and architectural review boards delaying starts. Several Oak Hills communities enforce design standards that cover roof lines, fence height, and exterior color. A good general contractor files those applications early and builds the review timeline into the schedule, so the HOA doesn’t stall the framing crew.

FAQs About General Contractor in Oak Hills
Yes, almost any kitchen remodel that touches plumbing, electrical, or load-bearing walls requires a permit through San Bernardino County Building and Safety, since Oak Hills is unincorporated. Unpermitted work can void portions of your original builder warranty on affected systems. Penhallow pulls the permits and schedules the county inspections, so the work stays covered and the sign-off is on file when you sell. Call (936) 259-2607 for a free estimate.
Caliche hardpan is a calcium carbonate crust that sits just below the surface on most Oak Hills lots. It destroys standard auger bits and requires pneumatic hammers or rock-breaking equipment for footings, fence posts, and patio slabs. If your contractor doesn’t test for it and price it into the written quote, you’ll see a change order after the first day of excavation. We dig test holes during the estimate so the written number already includes rock-breaking.
Upgrade cabinet boxes, countertops, and plumbing fixtures first. Oak Hills’s freeze-thaw cycling and 40 – 50°F daily temperature swings cause cheap cabinet boxes to warp and cultured marble to crack faster than homeowners expect. A kitchen remodel in Oak Hills runs $14,000 – $45,000. Flooring and lighting can usually wait unless the subfloor shows water damage. Call (936) 259-2607 to get an exact quote.
Several Oak Hills communities enforce design standards that cover rooflines, fence height, exterior color, and even the placement of detached structures. We file architectural review applications early and build the board’s approval timeline into the construction schedule. Ignoring the HOA usually means torn-down work and a fine. Better to file first and frame once.
In many cases yes, but the county’s agricultural and rural land-use overlays determine what’s allowed. A new ADU in Oak Hills runs $90,000 – $220,000, and a detached workshop or equestrian structure is priced on the same square-foot basis with additional grading and caliche excavation considerations. We check the parcel’s zoning, test the soil, and quote the work in writing before you commit. Call (936) 259-2607 to schedule a property walk.
