Fast, Reliable Home Remodeling Across Los Serranos
A full-scope Home Remodeling contractor in Los Serranos needs to understand one thing before quoting a single number: this is an unincorporated foothill community, which means San Bernardino County permitting rules apply, not city rules. Hillside and fire-hazard designations routinely stall projects that would sail through in Chino Hills or Yorba Linda. Our team works Los Serranos parcels weekly, so we plan for those reviews from day one. If you’re planning a kitchen, bath, whole-home, or addition scope, call Ruben Montoya at Stallion Contractors: (855) 600-3192. The estimate is free, and the price you get is the price we build to.

Why Stallion Contractors Is Los Serranos’s Preferred Home Remodeling Company
Los Serranos homeowners tend to ask the same two questions: how fast can you get here, and do you actually know how County Land Use Services works on a hillside parcel. The answer to both is yes. We serve the 91709 zip code directly, and our crews run jobs from the equestrian lots near the canyon edges to the mid-century ranch homes tucked off Sleepy Hollow. Homeowners don’t have to explain to us what a fire-hazard zone means for exterior assembly choices or why an over-the-counter permit can stall. We already know.
Our Los Serranos customers consistently point to one thing in their feedback: the contract stays predictable even when the walls open up. That’s not luck. It’s how we scope. We write allowances for framing, electrical rough-in, and waterproofing repair into every whole-house remodel quote, because in this housing stock those surprises are routine, not rare. Led by Ruben Montoya, our crew has rebuilt enough 1950s and 1960s ranch homes in Los Serranos to know exactly where the trouble hides.
We’re not the cheapest bid in Los Serranos, and we don’t try to be. We’re the contractor that shows up with County-ready plans, a single point of accountability across every trade, and access to more than 50 vetted brand partners. That combination matters more on a hillside parcel than a low number on a napkin.

Home Remodeling Companies in Los Serranos
Home Remodeling Companies in Los Serranos operate under conditions most contractors down the hill never face. A whole-home or major remodel here sits inside San Bernardino County’s unincorporated jurisdiction, meaning a standard permit can trigger both building and fire reviews, plus Hillside/Environmental constraints when the parcel touches sloped ground or a hazard zone. A kitchen remodel in Los Serranos typically runs $14,000 to $45,000, while a bathroom remodel falls between $9,000 and $28,000. Cabinet installation alone runs $4,000 to $13,000. The office counter in Chino Hills won’t ask for grading plans. The County counter will.
County-Ready Scoping
Before we pull a permit in Los Serranos, we check the parcel against County overlays: hillside, fire hazard, drainage, grading. If any apply, those plans go to the counter with the application on the first visit. That single step saves weeks of back-and-forth.
Trade Overlap Under One Contract
Los Serranos remodels often cross from interior work into exterior fixes: a roofline that needs repair, a side yard that needs regrading, a patio that needs hardscaping. We handle all of it under one contract, one team, one accountable point. You don’t chase subs.
Whole House Remodel in Los Serranos
A Whole House Remodel in Los Serranos means opening walls on housing stock that runs from mid-century ranches on large lots to newer hillside custom builds. Most of the homes we open up date from the 1950s and 1960s, with undersized framing, outdated electrical, and failed waterproofing behind the drywall. A whole house remodel here typically runs $45,000 to $130,000 depending on square footage, foundation condition, and the number of systems being replaced. Kitchen scope inside that project runs $14,000 to $45,000, home additions from $45,000 to $130,000, and countertop installation from $2,000 to $6,500 with Cambria, Silestone, or Caesarstone surfaces.
Inspection-First Walkthroughs
Every whole-house scope in Los Serranos starts with an inspection walk. We look at the foundation, the electrical panel, the roof framing, the waterproofing at the base of exterior walls. The report drives the allowance line items, so you know before demo starts what the likely exposure is.
Written Allowances, Written Change Orders
When a wall comes down on an older Los Serranos ranch and we find cloth-wrapped wiring or a rotten sill plate, that repair is covered by a written allowance we already priced into the contract. If the scope exceeds it, you get a written change order with a firm number before we touch anything else. No surprise invoices at the end.

Trusted Brands We Service in Los Serranos
Our Los Serranos customers pick from professional-grade product lines, not showroom upsells. Cabinetry runs through KraftMaid and Wellborn. Countertops come from Cambria, Silestone, and Caesarstone. Roofing ties to GAF, CertainTeed, and Owens Corning. Windows and doors trace to PGT and Therma-Tru. For ADU and prefab work, we’re partnered with Abodu, Dvele, and Mighty Buildings, which gives Los Serranos homeowners an option beyond stick-built additions. We hold local stock for the common repair items in the 91709 area, and our supplier relationships mean shorter lead times on special-order materials than a one-off contractor can arrange.

AfterCommon Home Remodeling Problems We See in Los Serranos Homes
- Cloth-wrapped wiring and outdated panels in mid-century ranches. The 1950s and 1960s homes around the Sleepy Hollow area and the equestrian lots were built before modern electrical loads. Once walls open, a panel upgrade and rewire become mandatory code items, and permits trigger them.
- Failed waterproofing at the base of exterior walls. Los Serranos sees hot, dry summers followed by concentrated winter rain, and hillside drainage pushes water against foundations. We routinely find rotted sill plates and compromised sheathing behind otherwise clean drywall.
- Undersized or damaged headers on load-bearing walls. Open up a wall in an older ranch and you often find a header that never should have been signed off. We replace it, price it as a change order, and get it inspected before anything else moves.
- Grading and fire-clearance stalls at the County counter. Parcels that touch hillside or fire hazard zones won’t clear an over-the-counter permit without grading and fire-clearance plans submitted with the first application. Contractors who don’t know this lose weeks mid-project.

FAQs About Home Remodeling in Los Serranos
Los Serranos is unincorporated, so permits route through San Bernardino County Land Use Services, not a city building department. When the parcel touches a hillside or fire hazard zone, the County requires grading and fire-clearance plans before an over-the-counter permit can clear. Chino Hills runs its own building department and typically doesn’t layer those reviews on the same scope. We include those plans in the first permit package, which cuts weeks off the timeline. Call (855) 600-3192 if you want a permit-ready scope before you commit.
The most common finds are cloth-wrapped wiring, failed waterproofing at the base of exterior walls, and undersized load-bearing headers. Homes from the 1950s and 1960s around the equestrian lots and Sleepy Hollow area were built to electrical and framing standards that don’t meet current code. A whole-house remodel will trigger panel upgrades and likely repair work on structural elements. We inspect first and write allowances for exactly these items.
We write allowances into the contract for the repairs we expect to find, and we price anything beyond the allowance as a written change order that you approve before we proceed. On a mid-century ranch off Sleepy Hollow, our crew found cloth-wrapped wiring and a subfloor that had been sistered one too many times over a settled slab. We brought grading and fire-clearance plans to the County counter with the permit package, wrote allowances for framing and electrical rough-in, and priced the undersized header as a written change order before touching it. That’s the process on every Los Serranos job.
Yes, in most cases. Los Serranos properties on hillside or canyon edges fall into wildfire-prone zones, so the County reviews exterior assemblies for fire resistance. That can affect siding, roofing, decking, and window choices. We draw on James Hardie siding and GAF, CertainTeed, and Owens Corning roofing lines to meet the requirement without sacrificing the look you want.
The County inspects structural framing, electrical, plumbing, mechanical, and fire-compliance items like defensible space and exterior assembly ratings. A missed item on a load-bearing wall fails the inspection and pushes your draw schedule back. We walk the job before every inspection to make sure the opened-wall work is signed off the first time. Estimates are free: call (855) 600-3192.
