Fast, Reliable Home Remodeling Across Montclair
Home remodeling in Montclair typically runs $9,000 – $45,000 depending on scope, with whole house remodels landing between $14,000 and $130,000 when additions or structural work are involved. The single biggest factor in a Montclair quote isn’t the finishes you pick. It’s what’s hiding behind the original 1950s – 70s sheetrock. We’ve worked enough tract houses off Holt Boulevard and Mission Boulevard to know that opening a wall here usually means finding things that were never in the original scope, and we price for that reality up front. If you’re planning work on an older Montclair home, call Timberline Contractors at (866) 253-5808 and we’ll walk the property with you before any numbers get written down.
Why Timberline Contractors Is Montclair’s Preferred Home Remodeling Company
Nelson Fung built Timberline Contractors around a simple idea: every phase of a remodel, from the foundation to the ridge cap, should be accountable to one contractor. Montclair homeowners deal with a specific set of problems you won’t find in new-build cities like Ontario Ranch or Eastvale. The housing stock here is almost entirely postwar tract homes and small stucco bungalows, built when two-wire electrical and cast-iron drain lines were standard. That’s not a problem if you know it’s coming. It’s a budget-killer if you don’t.
We bring Home Remodeling expertise that spans the full scope of what Montclair houses actually need: interior remodels, structural retrofits, roof and window packages, and rear-yard ADUs squeezed onto lots where every inch matters. Our customers don’t juggle five separate trades. One contract, one schedule, one person to call when something changes. That matters when an inspector requires a panel upgrade mid-project, or when the slab under a 1962 bungalow near Ramona Avenue turns out to have been poured without rebar.
We’re not the cheapest bid you’ll get in Montclair. We’re the bid that already accounts for what the other guy is going to “discover” in week three. That’s the difference between a remodel that closes on budget and one that dies in change orders.

Whole House Remodel in Montclair
A Whole House Remodel in Montclair usually means taking a 1950s – 70s tract house down to the studs in phases and rebuilding the systems, not just the surfaces. We’re not talking about paint and cabinet pulls. We’re talking about rewiring rooms that still have original cloth-insulated conductors, re-plumbing galvanized lines that have corroded to half their diameter, and leveling floors that have settled over decades of Inland Empire clay movement. On one small postwar tract house off Holt Boulevard near the 10 freeway, our crew opened a kitchen wall for a whole house remodel and found original two-wire cloth-insulated wiring and a subfloor that had been furred out to hide a slope. We stopped, wrote a change order for the rough-in and repair, and got it approved before the drywall went back up. The homeowner picked KraftMaid cabinets and a Cambria countertop against the corrected budget, and the punch list closed out only after the inspection sign-off came through.
Whole house remodels in Montclair generally run $14,000 – $45,000 for the core work. That number moves when a home addition is part of the plan, which pushes the total toward the $45,000 – $130,000 range. We write allowances into every contract for the mechanical and structural items we expect to find in this housing stock. When something else surfaces, it’s priced and approved in writing before we touch it. Our exterior envelope work ties into the interior scope, so you’re not patching a leaky flat roof one year and redoing the ceiling below it the next.
Structural and Systems Retrofit
Before finish materials get ordered, we inspect what’s behind the walls and under the floors. That means looking at the original framing, the wiring, the water lines, and the drainage. On Montclair’s 1950s – 70s tracts, we routinely find undersized floor joists, non-existent insulation, and panels that were never designed for a modern kitchen or a mini-split system. We fix those first, because a Cambria countertop on a failing subfloor is a waste of money.
Interior Finishes and Layout
Once the bones are sound, we get into the part most people actually enjoy: opening up small galley kitchens, removing a bearing wall (with proper beam replacement and engineering), and reworking tight bathrooms into rooms that make sense for how people live now. We bring the showroom to the project, with cabinetry from KraftMaid and Wellborn, counters from Cambria, Silestone, and Caesarstone, and plumbing fixtures from the majors like Kohler, Toto, and Grohe. You choose the tier, from performance-grade to premium, and we build it.
Luxury Home Remodeling in Montclair
Luxury Home Remodeling in Montclair isn’t about slapping a marble backsplash on a 1968 stucco bungalow and calling it done. It’s about bringing the entire envelope and the systems up to the level of the finishes you’re installing, so the whole house performs like a modern build instead of looking like one on the surface. Montclair’s dry Santa Ana winds and hot inland summers put real stress on roofs, stucco, and exterior trim. A luxury remodel here has to be engineered for that, not just styled for Instagram.
Expect to budget $45,000 – $130,000 on a true luxury scope in Montclair, depending on footprint and whether an addition or second-story element is involved. That budget includes the parts you never see but absolutely feel: Schluter-system waterproofing in wet areas, proper ventilation, upgraded electrical service, and insulation that actually holds temperature during a Pomona Valley heat wave. It also includes materials with documented performance, which is why we align with manufacturers like James Hardie, Therma-Tru, and premium hardscaping brands including Unilock and Techo-Bloc for outdoor living tied to the main structure.
Kitchen and Bath at a Different Level
We see a lot of Montclair homeowners who’ve lived with a problematic kitchen or bath for years and are done making cosmetic fixes. When we build a luxury kitchen here, we start with the layout and the systems, then layer on Cambria quartz or Caesarstone, full-height backsplashes, and cabinet runs from KraftMaid or Wellborn. Baths get full waterproofing systems, curbless or walk-in showers, and Toto or Grohe fixtures. These aren’t catalog jobs. They’re built around the actual constraints of your house.
Indoor-Outdoor Living Tied to the House
Montclair’s narrow lots don’t leave much room for error. A rear patio done right, with Unilock or Cambridge Pavers and proper drainage, extends the living space without eating the entire yard. When we’re already managing the interior remodel, we handle the hardscaping, the grading, and the drainage in the same contract. That way, the patio door lands where it should and water doesn’t pool against the foundation.
Trusted Brands We Service in Montclair
We don’t push a limited catalog at Montclair customers. We work with 50-plus vetted brand partners across every major construction category, so your material choices stay flexible even after the project starts. That includes roofing from GAF, CertainTeed, Owens Corning, and IKO, siding from James Hardie, windows and doors from Therma-Tru and PGT, and hardscaping from Unilock, Techo-Bloc, and Cambridge Pavers. We keep common material lead-times visible and order early enough that a cabinet run or a window package doesn’t stall the job. That matters on a remodel where the inspection schedule and the material schedule have to hold hands.

AfterCommon Home Remodeling Problems We See in Montclair Homes
- Original two-wire electrical and overloaded panels. Most 1950s – 70s Montclair tract houses weren’t built for induction cooktops, EV chargers, or modern HVAC. Opening walls frequently exposes cloth-insulated wiring that has to be replaced before the inspector will sign the rough-in.
- Failed waterproofing in original baths and exterior transitions. The low-pitch roofs and flat roof sections common on Montclair’s older builds don’t shed water like a modern steep-pitch roof. We find rotted framing at the roof-wall junction and failed shower pans that have been leaking into the subfloor for years.
- Clay soil movement and slab cracks. The Pomona Valley’s expansive clay soils shrink in hot dry spells and swell during seasonal rain. That movement shows up as door frames out of square, cracked slabs, and foundation offsets that nobody notices until a remodel opens things up.
- Illegal or unpermitted past work. A lot of Montclair homes have had additions, patio enclosures, or garage conversions done without permits over the decades. When we pull a permit for your remodel, the inspector will ask about anything that wasn’t on record. We deal with that before it becomes your problem.

FAQs About Home Remodeling in Montclair
Because this city’s housing stock is almost entirely 1950s – 70s tract homes, and what’s behind the original sheetrock is usually original two-wire wiring, galvanized plumbing, and framing that doesn’t meet current code. Nearly every remodel permit in Montclair is issued for retrofit work inside or behind an existing house, so the inspector signs off on what’s been brought current, not on clean-slate assemblies. We minimize surprises with a pre-construction inspection and written allowances, but when something outside the allowance surfaces, it’s priced and approved in writing before we touch it. Call (866) 253-5808 for a walkthrough and an honest quote.
Yes, for almost any remodel beyond paint and flooring. Montclair is a fully built-out city, so nearly every permit issued here is for retrofit work on an existing 1950s – 70s house, not new construction. That means the inspector is checking to see that wiring, plumbing, and framing behind the walls meet current code once they’ve been opened. We pull permits and handle inspections as part of our contract. Call (866) 253-5808 to discuss your project.
Usually yes, but it’s a game of inches, not feet. Montclair’s postwar tracts have tight setbacks, and we routinely hit the property-line setback or an existing block-wall fence right where the new foundation is supposed to go. We work within those constraints with proper engineering and off-the-shelf prefab partners like Abodu and Boxabl when the site suits it. An ADU on a typical Montclair parcel runs $90,000 – $220,000. Call (866) 253-5808 and we’ll measure your lot before anyone draws a plan.
We don’t take the entire job value up front. Payments are staged against specific milestones, so you’re paying for completed work, not promises. On a whole house remodel, that usually means a contract deposit followed by draws tied to rough-in, inspection sign-offs, drywall, finishes, and final walkthrough. Any change order is priced and approved in writing before the additional work starts. Call (866) 253-5808 and we’ll walk you through a sample payment schedule for your scope.
A kitchen remodel in Montclair typically runs $14,000 – $45,000. A bathroom remodel runs $9,000 – $28,000. The spread depends on whether you’re replacing surfaces or opening walls, whether the electrical panel needs an upgrade, and which material tier you choose, from performance-grade to premium brands like Cambria, KraftMaid, and Toto. We’ll give you a line-item quote with those choices broken out, so you decide where the money goes. Call (866) 253-5808 for a free estimate.
