Home remodeling in Los Serranos runs $14,000 – $45,000 for a typical kitchen and $45,000 – $130,000 for a full home addition, with high-end custom work scaling from there. We’re Milpitas Construction, led by Ken Stafford, and we work throughout the 91709 hills and canyon-edge streets where grading, slope drainage, and county permitting shape every project. If you’re planning a whole-house remodel, a luxury kitchen, or an ADU on a foothill lot, call (877) 752-4194 for a free estimate and a written scope of work before anything gets ordered.
Why Milpitas Construction Is Los Serranos’s Preferred Home Remodeling Company
Los Serranos is not Chino. The lots here sit on cut-and-fill graded terrain at the base of the Chino Hills, and a remodel often starts with geotech review before a single wall comes down. We know that because we’ve done it here. Our team manages the full scope under one contract, so the same crew handling your foundation and drainage also coordinates the Wellborn cabinetry, Cambria countertops, and Kohler fixtures going into the finished space. Homeowners in Los Serranos repeatedly tell us the difference is that we name materials by brand and lock pricing before releasing long-lead orders.
Ken Stafford runs every Los Serranos project with a single point of contact. When a homeowner near the Chino Hills State Park edge calls about an addition, we’re not sending three different subcontractors to look at the same hillside. We show up, walk the lot, check the existing retaining walls and drainage lines, and come back with a plan that accounts for the county permit path, the soil, and the schedule. That’s why local referrals carry most of our Los Serranos work.
Styles & brands we work with







Whole House Remodel in Los Serranos
A Whole House Remodel in Los Serranos usually means taking a 1970s – 1990s tract home or a larger foothill custom home down to the studs in phases, reworking the floor plan, and rebuilding it around modern loads and fire-rated assemblies. On hillside streets, the job often includes structural reinforcement, slope drainage upgrades, and new retaining walls before finish work begins. A full whole-house remodel in this area runs $45,000 – $130,000 depending on square footage and scope, with high-end custom work scaling higher when architectural glass and custom millwork are involved.
Structural and Site Work First
Before cabinets or tile matter, the lot has to work. That means evaluating the original cut-and-fill pad, checking whether the tract-era retaining walls can handle an expanded footprint, and replacing undersized drainage lines where winter rains expose failures. We pull county permits, coordinate the geotech review, and get the structural corrections done before the rough-in.
Finish Selection Without Stalling the Schedule
The long-lead items on a Los Serranos whole-house remodel are the custom cabinets, architectural glass, and specialty doors. We order from brands like Wellborn, KraftMaid, and Therma-Tru after the permit set is approved, not before. That ordering sequence is the difference between a project that holds its schedule and one that eats change orders.
Luxury Home Remodeling in Los Serranos
Luxury Home Remodeling in Los Serranos is a different animal from production-grade work in neighboring Chino or Montclair. Here, the schedule is driven by custom millwork, architectural glass, and designer finishes, not labor availability. On the foothill custom homes near Chino Hills State Park, a kitchen rebuild with Wellborn cabinetry, a Cambria island, and Kohler fixtures typically lands between $14,000 and $45,000 for the kitchen scope alone, with full luxury remodels scaling well beyond when specialty glass and custom interior doors enter the mix.
Architect and Designer Coordination
We work directly with architects and interior designers on Los Serranos luxury projects. The plans get stamped, the county reviews them, and we translate the design intent into a fixed written scope before anything is ordered. That coordination is what keeps a high-end remodel from drifting into a series of expensive surprises.
Lead Times Set the Calendar
Custom cabinetry from Wellborn, specialty glass packages, and designer plumbing from Kohler or Grohe routinely run 8 – 16 weeks out. Labor is rarely the bottleneck on this tier. We set the draw schedule around confirmed lead times and fix the price in writing before releasing those orders, so the finishes land when the framing is ready for them.
On a foothill custom home near the Chino Hills State Park edge, our crew rebuilt a kitchen around Wellborn cabinetry and a Cambria island, but the real work was coordinating architect-stamped plans, county permits, and replacing an undersized slope-drainage line before the rough-in could pass. We locked the scope of work and allowances in writing and fixed the price before releasing the long-lead cabinet and glass orders, so the Santa Ana-rated exterior assemblies and designer finishes landed on the draw schedule instead of stalling it.
Trusted Brands We Service in Los Serranos
We spec materials by name, so you know exactly what’s going into your home. For Los Serranos remodels, that means Cambria and Silestone countertops, Wellborn and KraftMaid cabinetry, and Kohler plumbing fixtures drawn from our verified portfolio of 50+ brand-name product lines. We maintain direct ordering relationships with these manufacturers, which means local homeowners in the 91709 hills aren’t waiting on big-box backorders when a countertop or cabinet order needs to move. From the roofline to the kitchen counter, it’s one contractor, one conversation.

AfterCommon Home Remodeling Problems We See in Los Serranos Homes
- Undersized slope drainage on original tract lots: Many 1970s – 1990s homes in Los Serranos were built with drainage systems that weren’t engineered for today’s addition and ADU loads. Winter rains expose the failure, and by then the remodel is already underway.
- Cut-and-fill foundation movement: Hillside clay soil expands and contracts with dry summers and wet winters. We routinely find subfloor and foundation issues that surface after demolition, which is why we assess the pad before the price is fixed.
- Ordering custom finishes before permits are final: We see Los Serranos homeowners get burned when custom cabinetry or architectural glass is ordered while the county permit set is still under review. A grading or structural shift triggers a change order the owner has to eat.
- Thin finish allowances on luxury work: Designer millwork and specialty glass lead times, not labor, reset the schedule on high-end Los Serranos remodels. Carrying inadequate allowances means the project stalls mid-build waiting on materials.

FAQs About Home Remodeling in Los Serranos
Because Los Serranos is unincorporated San Bernardino County, so your remodel clears county building and planning rather than a single city department. The review path adds time, and on hillside streets the geotech and drainage review runs alongside the standard permit review. A high-end Los Serranos remodel with custom cabinets and architectural glass typically schedules 2 – 4 weeks longer than a comparable Chino project at the front end. Call (877) 752-4194 and we’ll map the actual timeline for your lot.
Yes, most hillside and canyon-edge remodels in the 91709 area need grading and drainage review beyond the standard building permit. If the original tract-era retaining walls aren’t rated for the added load of an addition or ADU, the county will require geotech input and structural corrections before the rough-in is approved. We handle that review as part of the remodel scope, not as a separate project you hire someone else to manage. Call (877) 752-4194 to get a read on your specific lot.
We fix the price and the allowances in writing before releasing any long-lead orders, so a late finish selection doesn’t become a change order. The risk in Los Serranos luxury work is ordering custom millwork or architectural glass while the permit set is still moving through county review, then eating the cost when a grading shift changes the structural layout. Our process ties the finish order schedule to the approved permit set and the confirmed lead times. That’s how the budget holds. Call (877) 752-4194 for a written quote.
Yes, we order Wellborn and KraftMaid cabinetry and Cambria or Silestone countertops regularly for Los Serranos kitchens in the 91709 hills. Lead times on these lines run 8 – 16 weeks, so we confirm the cabinet and top selections against the approved permit set and lock the order in before the rough-in closes. That sequencing keeps the hillside site work and the finish schedule from fighting each other. Call (877) 752-4194 to see the full cabinet and countertop line sheets.
Expect fire-rated roofing, siding, and window assemblies as a real line item, not boilerplate. On Los Serranos hillside streets toward the Chino Hills State Park edge, Santa Ana wind exposure drives upgraded roof decking, impact-rated windows, and fire-resistant exterior cladding. We spec those assemblies by brand, including GAF roofing and James Hardie siding, and factor them into the written quote from day one. Call (877) 752-4194 for an exact number on your project.
