Remodeling Company in Los Serranos, CA
Home renovation in Los Serranos means working with a housing stock that spans three distinct eras: mid-century ranch homes, horse-property ranchettes with detached outbuildings, and newer tract subdivisions climbing into the Chino Hills foothills. That mix changes everything about how a renovation should be approached, from foundation work on expansive clay to fire-hardening exteriors ahead of Santa Ana season. San Mateo Construction has served Los Serranos since 2018, and we manage the whole scope under one contract, from roofline to foundation. Call (855) 901-7266 to talk through your project.
Why Los Serranos Homes Are Different
Los Serranos was its own community before Chino Hills incorporated in 1991, and that history still shows up in the lots and the paperwork. Many parcels carry legacy lot lines and County-era improvements that predate current Chino Hills building codes, so a renovation often starts with reconciling what’s on file against what’s actually in the ground. Contractors who only work the newer master-planned tracts in Chino Hills rarely see this. We do, regularly.
The terrain adds another layer. Sloping lots along the Chino Hills State Park edge sit on expansive clay soils that move with moisture, which means drainage corrections, retaining walls, and foundation assessments are routine parts of a Los Serranos renovation, not add-ons. Hot, dry summers and Santa Ana wind events push exterior material choices toward fire-resistant options, and summer heat shapes scheduling for any exterior work. If you’re planning an addition, an ADU, or a full interior remodel, these conditions should drive the plan from day one.
Homes here don’t fall into one neat era. You’ll find 1960s ranches that need full electrical and plumbing updates beside 1980s horse properties with detached garages that make natural ADU conversions, and newer hillside customs where the challenge is grading and access. That breadth is exactly why a single accountable contractor matters: the same team that corrects your drainage can re-roof the house, rebuild the kitchen, and convert the garage without handing you off between trades.
Styles & brands we work with
Our Main Los Serranos Services
Most Los Serranos homeowners call us for one of two things: whole-project leadership through a general contracting engagement, or a defined home remodel with a clear scope and finish timeline. Both are covered below, with dedicated Los Serranos pages for the full detail.
General Contractor in Los Serranos
When your project spans multiple trades, a general contractor is the difference between one accountable team and a string of separate vendors you coordinate yourself. In Los Serranos, that coordination gets complicated fast: a kitchen remodel may require plumbing updates on a 1960s slab, electrical work through legacy framing, and drainage corrections on expansive clay before the finish work starts. We manage permits, scheduling, material procurement, and quality control across every trade, with brand selections from GAF roofing to Cambria countertops handled through one conversation. Learn more about our General Contractor in Los Serranos services.
Home Remodeling in Los Serranos
Home remodeling here rarely means a single room for long. Because so many Los Serranos homes date to the mid-to-late 20th century, kitchens and bathrooms often need structural, electrical, and waterproofing corrections before finishes go in. We handle that sequence in the right order so you’re not tearing out new tile to fix an old leak. From walk-in shower replacements using Schluter waterproofing to full kitchen builds with KraftMaid cabinetry, the scope is defined up front and the price is fixed.

Home Renovation in Los Serranos
Home renovation in Los Serranos is less about cosmetic updates and more about reshaping homes that were built for a different era. A 1970s ranchette with a detached garage is a strong ADU candidate; a mid-century ranch on a sloping expansive-clay lot often needs drainage and foundation work before any interior finish makes sense. San Mateo Construction handles the whole sequence under one contract, and we help you choose materials from a curated brand portfolio so every dollar goes toward a vetted product. If you’re planning a broader renovation, our Home Renovation overview covers the full scope.
Home Renovation Contractors
Signs you need it
You need a renovation contractor when the project touches structural, mechanical, and finish work at once, or when a previous patch-up left you with recurring problems in the same area.
What it costs in Los Serranos
A full home renovation in Los Serranos typically runs from $45,000 for a focused scope to $130,000 for larger, multi-room work that includes structural or exterior corrections.
How we do it
We start with a site walk to map existing conditions against Chino Hills permit requirements, then produce a written scope, fixed line-item quote, and a schedule that sequences any drainage, structural, mechanical, and finish work in the right order.
Home Renovators
Signs you need it
When a home has good bones but dated systems, awkward layouts, or an interior that no longer fits how you live, a full renovation beats a series of piecemeal fixes.
What it costs in Los Serranos
Kitchen and bathroom renovation packages in Los Serranos typically fall between $14,000 and $45,000 for kitchens and $9,000 to $28,000 for bathrooms, with larger additions pushing higher.
How we do it
We demo carefully to preserve what’s reusable, correct any framing or mechanical issues revealed during the opening, then rebuild finishes using vetted brands like KraftMaid, Kohler, and Silestone with Schluter waterproofing in wet areas.
Home Improvement Contractors
Signs you need it
You need a home improvement contractor when multiple smaller projects, like windows, siding, and a bath update, have piled up and coordinating them separately is wasting your time and money.
What it costs in Los Serranos
Window replacement in Los Serranos runs $4,500 to $15,000, James Hardie siding projects vary by scope, and a bathroom vanity install is $800 to $3,000, so bundling work under one contract usually reduces total disruption.
How we do it
We group scopes into phases that minimize repeat mobilizations, order materials through our supplier network so lead times align, and run the work with one accountable project lead from start to finish.
Renovation Contractors
Signs you need it
When a renovation touches load-bearing walls, electrical panels, or plumbing rough-ins, or when the work requires Chino Hills permits and inspections, a licensed renovation contractor is the only sensible path.
What it costs in Los Serranos
Structural or permitted renovation scopes in Los Serranos typically start around $45,000 for a home addition and reach $130,000 or more when grading, retaining walls, and fire-hardening are included.
How we do it
We pull permits, schedule inspections, manage the trades, and keep a written change-order process so the number you approved is the number you pay unless you choose to add scope.

In Los Serranos, the biggest price drivers are lot slope, expansive clay conditions, and the era of the home’s mechanical systems. A 1960s ranch that needs full re-piping and a panel upgrade will land higher in the kitchen range than a 1990s tract home with modern rough-ins. We give written, fixed, line-item quotes so you know the number before work starts and it doesn’t move unless you change the scope.

What Los Serranos Customers Say
"Quality construction and a professional operation. Communication was strongest at the site meetings, and slower by email in between."
— Steven Wong"Framing crew was meticulous and the walls are straight everywhere. Drywall goes on a lot better when the framing is right."
— Diego Hernandez"Ground up build. Permits, foundation, framing, all of it, and he ran the schedule tightly enough that the subs were never tripping over each other. Finished within a month of a fourteen month estimate."
— Bethany Novak
