Fast, Reliable General Contractor Across Los Serranos
Finding a General Contractor who understands Los Serranos means finding someone who knows the difference between a flat Chino tract lot and a hillside parcel off Carbon Canyon. We’re Elmwood Contractors, and our crews work throughout the 91709 zip code on remodels, additions, ADUs, and exterior envelope projects that flatland contractors routinely underbid and under-engineer. If you’re planning a kitchen gut, a room addition, or a full interior and exterior renovation, call us at (866) 253-8554. We’ll walk the site with you, look at drainage and grading first, and give you a written scope before any long-lead material gets ordered.
Why Elmwood Contractors Is Los Serranos’s Preferred General Contractor Company
Los Serranos homeowners tend to ask harder questions than most. They’ve seen neighbors fight with contractors who quoted a kitchen and never mentioned that a hillside lot needs footing depth review, retaining-wall repair, or a drainage plan that survives a Santa Ana winter. Our reputation in this community comes from leading every project with site conditions, not allowances. We coordinate the full arc of the work, from interior finish packages to exterior envelope upgrades, under one project plan and one point of contact. When a Los Serranos homeowner calls us, they get Nolan Shepherd’s direct involvement on scope, product selection, and the schedule. Not a rotating cast of subs. Local builders know that Chino Hills grading review sets the real timeline on hillside streets. We plan around it rather than pretend it doesn’t exist.
Styles & brands we work with
Construction Company in Los Serranos
A construction company in Los Serranos has to handle what the foothills throw at a build before the finish work ever starts. We’re not a specialty sub and we’re not a box-store installer. We’re a single-source contractor managing the whole job: structural work, drainage, rough-in, dry-in, and the interior finish packages that high-end Los Serranos homes require. A typical home addition here runs $45,000 to $130,000 depending on foundation conditions and finish level. ADU construction in the 91709 area runs $90,000 to $220,000, shaped heavily by hillside engineering and utility trenching. We recommend products because they perform on Chino Hills foothill lots, not because they’re convenient for us.
Hillside Structural and Drainage Work
On the canyon-adjacent streets off Los Serranos Country Club, winter runoff exposes cracked retaining walls and settling foundations every few seasons. We sequence this work first so the rest of the project sits on stable ground. We don’t quote a room addition without looking at what the slope does in a heavy rain.
Prefab and Ground-Up Additions
For homeowners who want a faster path to square footage, we carry relationships with prefab and ADU manufacturers like Abodu, Dvele, and Mighty Buildings. That’s a capability most traditional remodelers in this market simply don’t have. We still handle the site work, foundation, and finishes so the prefab package ties into the hillside correctly.
Remodeling Contractor in Los Serranos
A remodeling contractor in Los Serranos works on homes where the finish bar is high and the site conditions are unforgiving. Kitchen remodels here typically run $14,000 to $45,000. A bathroom remodel runs $9,000 to $28,000. Those numbers mean something different on a hillside lot when the project requires structural sign-off before the custom cabinetry order goes in. We run interior remodels and exterior envelope work as one coordinated scope, because a kitchen renovation that ignores a failing drainage swale outside the foundation is a warranty problem waiting for the next storm. We name the brands going into your home before the contract is signed.
Custom Kitchen and Bath Packages
We specify cabinetry from KraftMaid and Wellborn, stone surfaces from Cambria, Silestone, or Caesarstone, and plumbing fixtures from Kohler, Moen, Toto, or Grohe. You’ll see the exact product line and price tier before you commit. The goal is a written allowance structure that doesn’t drift.
Architect and Designer Coordination
Many Los Serranos projects involve an architect or interior designer. We work directly with them on submittals, product specs, and the construction schedule so the design intent doesn’t get lost between a drawing set and a rough-in inspection. We prefer written change orders over verbal agreements, every time.
Trusted Brands We Service in Los Serranos
We stock and install across a defined product roster, so Los Serranos customers are never told “whatever the supplier has in the yard this week.” For exterior doors, we work with Therma-Tru. For impact-rated and architectural glass systems, we specify ViewLux and Mr-Glass products where the design calls for them. For fencing and perimeter work, Barrette and Master Halco give us spec-grade options at multiple price points. We keep long lead times visible from day one so cabinet slabs and door packages don’t ambush the schedule. The right material for your budget and your climate, chosen from a vetted lineup, not a single supplier’s catalog.

AfterCommon General Contractor Problems We See in Los Serranos Homes
- Ordering custom finishes before grading and structural approvals clear. A homeowner falls in love with a Cambria slab or Wellborn cabinet line, the order goes in, and then Chino Hills grading review takes longer than expected. The slab sits in storage, or worse, arrives mid-demolition and there’s nowhere to put it.
- Treating a hillside lot like a flatland Chino tract job. Contractors from outside the foothill communities often miss the retaining-wall and drainage work that winter storm runoff exposes on Los Serranos hillside streets. The visible remodel looks fine until the next heavy rain.
- Quoting off verbal allowances instead of written allowances and change orders. High-end finish selections creep. A contractor says “allowance for stone,” the homeowner picks a premium product, and the fixed price is no longer fixed. We write the allowances down and sign them.
- Separating interior and exterior work across multiple contracts. A kitchen remodel runs through one company, the roofing and siding through another, and the drainage work gets forgotten entirely. By the time the project ends, nobody owns the full envelope. One contractor, every trade, interior to exterior.

FAQs About General Contractor in Los Serranos
Because custom cabinetry from Wellborn or KraftMaid and stone slabs from Cambria or Caesarstone are ordered weeks or months in advance, and Chino Hills grading and structural reviews set when we can even begin. The labor is available. The material isn’t always, and the permits aren’t either. On a hillside street off Carbon Canyon, the schedule is governed by when drainage and slope work clears review, then by when the long-lead finishes land. Call (866) 253-8554 for a realistic timeline on your specific project.
A kitchen remodel or addition on a foothill lot in 91709 can trigger grading, drainage, and retaining-wall review that a flatland contractor never encounters. If your parcel sits on a slope, the permit path includes slope stability and runoff management before finish work starts. We sequence around those approvals instead of letting them blindside the schedule. That’s why we look at the lot first and pick finishes second.
We write allowances and sign them. Every line item, from the Wellborn cabinet line to the Cambria island top, gets a dollar range and a selection deadline. If you choose within the allowance, the price doesn’t move. If you upgrade, we write a change order and you approve it before we order. Nothing gets purchased on a verbal understanding. Call (866) 253-8554 and we’ll walk you through exactly how that works on paper.
Frequently, yes. On the hillside streets off Los Serranos Country Club and down toward Carbon Canyon, winter storm runoff pools against foundations and retaining walls, and we’ve rebuilt settling rear foundation walls and re-graded downslope drainage before starting the interior work. If your remodel adds square footage or changes rooflines, the water has to go somewhere. We’ll tell you whether your drainage is adequate or whether you’re buying a problem that shows up next winter.
Everything that changes the shape, structure, or finish of the home. We coordinate submittals, product specs, structural drawings, and the construction schedule with your architect or designer so the vision survives contact with hillside reality. On a recent Carbon Canyon hillside project, our crew rebuilt a settling rear foundation wall and re-graded the downslope drainage before starting a kitchen gut that specified Wellborn cabinetry and a Cambria island top. The cabinetry and slab were the long-lead items, so we locked allowances and the draw schedule in writing and placed the orders only after inspection sign-off on the rough-in and structural work. When the winter runoff backed up mid-project, we wrote a change order for added footing depth rather than absorb it into the punch list. That’s how it should work.
