Fast, Reliable General Contractor Across Los Serranos
When a Los Serranos homeowner starts pulling back drywall on a mid-century ranch, they usually find more than they bargained for. Aluminum wiring. Framing that was undersized from day one. Waterproofing that quit doing its job years ago. Our General Contractor team has worked enough Los Serranos jobs to expect these discoveries, and we price them accordingly. You’ll get a contractor who knows that every permit here runs through San Bernardino County, not Chino Hills, and who writes allowances into the contract so nothing on your remodel becomes a surprise. Call Square Deal Contractors at (866) 623-7205 for a free estimate on your project.
Why Square Deal Contractors Is Los Serranos’s Preferred General Contractor Company
Los Serranos sits in a jurisdictional odd spot: an unincorporated county island surrounded entirely by Chino Hills. That changes how every project gets permitted, inspected, and built. A contractor who assumes Chino Hills rules will get stopped at the first San Bernardino County inspection, often over a setback or grading condition the crew never thought to check. We know the county’s plan check rhythm, we know which inspectors work this area, and we schedule our rough-in sign-offs to match county timelines, not city ones.
Homeowners here tell us the same thing after their first remodel with us: the biggest relief wasn’t the finished kitchen or the new bath. It was knowing someone had already thought through what was behind the walls before the first swing of a hammer. Led by Nolan Breckett, our team has built a reputation in Los Serranos for written change orders, line-item allowances, and a willingness to explain exactly why a beam needs to be engineered instead of just replaced.
We also carry the material depth that a full-scope remodel demands. More than 50 vetted manufacturer lines give us the flexibility to pair a Grohe fixture with a dependable American Standard option in the same home, or match CertainTeed roofing to a budget without sacrificing the installation quality. That matters here, where homes range from 1950s ranches to newer hillside customs, and no two budgets look the same.
Styles & brands we work with
Construction Company in Los Serranos
A construction company in Los Serranos takes on the structural work that remodels reveal: bearing walls that need engineering, additions that need county-setback review, and exterior envelope upgrades that fire-hazard code now requires. A typical room addition in Los Serranos runs $45,000 – $130,000, while a full ADU construction project lands between $90,000 and $220,000 depending on grading, foundation needs, and the modular or site-built path you choose.
Additions and Detached Structures
Many Los Serranos lots carry equestrian or agricultural zoning, which means larger setbacks and specific grading rules on any detached garage, shop, or ADU. We check the county’s requirements before we quote, so you’re not surprised by a rejected plan check halfway through design.
Roof and Envelope Work
Hot inland summers and Santa Ana wind events mean Class A roofing and ember-resistant vents are common upgrades on older hillside homes. A roof replacement in Los Serranos typically runs $8,000 – $20,000, and we bid it with the fire-hazard code already factored in rather than as a change order after the fact.
Remodeling Contractor in Los Serranos
A remodeling contractor in Los Serranos does the finish work and the demolition that exposes what’s underneath. On 1960s ranch homes along Los Serranos Road and the surrounding streets, that often means opening a wall for a kitchen remodel and finding aluminum branch wiring spliced into newer romex, or a subfloor gone soft from a slow leak that predates the current owner. A kitchen remodel here runs $14,000 – $45,000, and a bathroom remodel typically lands between $9,000 and $28,000. The price you can trust is the one that accounts for what’s behind the tile, not just the tile itself.
Kitchen Remodels
We write allowances into the contract for the unknowns: wiring, framing, subfloor repair. That way, when our crew finds the splice or the rot, it’s a documented change order you approve in writing, not a phone call asking for more money mid-demo.
Bathroom Remodels
Failed shower waterproofing is the most common hidden condition we see in Los Serranos baths from the 1960s and 70s. We open the walls, check the pan and the substrate, and bring the waterproofing to current code before any new tile goes up.
Trusted Brands We Service in Los Serranos
Our material portfolio runs deep: GAF and CertainTeed on roofing, Grohe and Sterling in the bath, plus a full range of cabinetry, countertop, and hardscaping lines across premium and value tiers. For Los Serranos clients, that means we can hold a material reservation locally and schedule delivery around your county inspection dates instead of making the project wait on a supply house. The brand choice is always yours. What matters to us is that whichever line you pick, the installation behind it is done to a standard that passes county inspection the first time.

AfterCommon General Contractor Problems We See in Los Serranos Homes
- County jurisdiction confusion: Contractors who pull permits as if Los Serranos were Chino Hills get red-tagged at the first San Bernardino County inspection over setbacks or hillside grading they never checked. We verify the county’s rules before we submit anything.
- Hidden wiring in mid-century ranches: Aluminum branch wiring was common in 1950s-70s construction, and when it’s spliced into newer romex without proper connectors, it’s a fire hazard. We stop, price the rewiring, and get it permitted before anything gets covered up.
- Outdated waterproofing: Shower pans and tub surrounds from 50+ years ago were built to standards that don’t meet current code. Opening those walls means bringing the waterproofing up, and we build that expectation into every bathroom quote.
- Hillside grading and drainage: The newer custom hillside builds from the 1980s-2000s often sit on lots where drainage wasn’t solved correctly the first time. County inspectors flag grading issues on additions and ADUs that city inspectors in neighboring communities would never raise.
Pricing for General Contractor in Los Serranos, CA
Here’s what you can expect to pay for major work in Los Serranos based on current local market rates:
| Project | Typical Los Serranos 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 |
| Roof Replacement | $8,000 – $20,000 |
What moves these numbers: the age of your home, what’s inside the walls, whether the county requires engineered drawings, and the material tier you select. A $14,000 kitchen remodel on a 1970s ranch with clean wiring and solid framing is a very different job from the same floor plan with aluminum wiring and a failed subfloor. We price honestly up front, write allowances for the unknowns, and hand you a change order in writing before any surprise becomes an invoice. Call (866) 623-7205 for a free, line-item estimate.

FAQs About General Contractor in Los Serranos
Los Serranos is an unincorporated county island completely surrounded by Chino Hills, so every permit, plan check, and inspection runs through San Bernardino County, not the city of Chino Hills. County inspectors apply county setback and grading rules to everything from ADUs down to patio covers. A contractor who doesn’t know this gets red-tagged at the first inspection. Ours doesn’t.
Expect aluminum branch wiring, undersized or damaged framing, and failed waterproofing in baths and around windows. These were standard construction practices of the era, and they’re all code triggers once you open the wall. We write allowances into every ranch remodel contract so these discoveries become documented change orders, not panicked phone calls. Call (866) 623-7205 and we’ll walk your specific home’s likely conditions before you commit.
We stop work, write a change order that prices the repair, hand it to you for written approval, and only then continue. On a 1960s ranch off Los Serranos Road, our crew found aluminum wiring spliced into romex plus a rotted subfloor under the sink. We priced the rewiring and subfloor repair, pulled the county structural permit, and held the draw schedule until the rough-in passed inspection. That’s the standard, not the exception.
Yes. Any remodel that touches structural, electrical, plumbing, or waterproofing work in Los Serranos requires a San Bernardino County permit. We pull the permits, schedule the inspections, and build to pass on the first visit. Working without a county permit creates a liability that follows the home into any future sale.
Class A roofing, ember-resistant vents, and defensible-space clearing are the three most common upgrades on older wood-sided hillside homes in Los Serranos. The hot inland summers and Santa Ana winds put this area in a high fire-hazard zone, and the county enforces those construction standards on any remodel that touches the exterior envelope. Call (866) 623-7205 to schedule your free estimate and get an exact scope for your home.
