Remodeling Company in Montclair, CA
Home renovation in Montclair means working with homes built between the 1950s and 1970s, mostly single-story tract houses with original framing, aging plumbing, and tight lots near the 10 freeway. Timberline Contractors has served Montclair since 2018, handling full-scope remodels, additions, and ADUs where every job involves opening walls and finding something the last remodel covered up. Call (866) 253-5808 to talk through what your house actually needs.
Why Montclair Homes Are Different
Montclair is a small, fully built-out city in the Pomona Valley. There is no greenfield left. Nearly every construction job here is a remodel, an addition, or a tear-down-and-rebuild on a parcel that has already been built on once. Most of the housing stock is post-WWII tract homes and small stucco bungalows from the 1950s through the 1970s, which means original wood-framed walls, galvanized supply lines that are past their design life, and flat or low-pitch roofs that were never meant to hold up to seventy years of inland sun.
The lots themselves shape the work. Montclair’s postwar tracts were laid out narrow and deep, so rear-yard additions and ADUs become a game of inches. Contractors routinely hit property-line setbacks and existing block-wall fences exactly where the new foundation needs to go. Hot inland summers and Santa Ana wind events stress stucco, roofing, and exterior finishes, while the Pomona Valley’s expansive clay soil moves enough between dry spells and seasonal rain that additions need more foundation attention than they would in a coastal city. Homeowners here do not get clean-slate builds. We plan for retrofit work.
Styles & brands we work with







Our Main Montclair Services
Montclair homeowners call us most often for two things: full-project general contracting where one team carries every phase, and complete home remodeling that addresses the interior and exterior at the same time.
General Contractor in Montclair
We run Montclair projects the way a general contractor should: one contract, one schedule, one point of accountability from demolition through final inspection. On these older tract homes, that means coordinating structural retrofits, mechanical upgrades, and finish work without turning your house into a six-month construction site with five different crews pointing at each other. The narrow lots and setback constraints here make coordination the single most valuable thing a contractor provides. General Contractor in Montclair services cover the full scope.

Home Remodeling in Montclair
Most Montclair remodels start with a kitchen or bath and expand once the walls are open. That is not a problem; it is the project telling us what it needs. We plan for it from the first estimate, so you are not surprised when a 1962 wall reveals wiring that should have been replaced in the Reagan administration. The goal is a remodel that holds up to this climate: hot summers, Santa Anas, and soil that shifts. Home Remodeling in Montclair means remodeling for the house you actually have, not the one in a photo.

Home Renovation in Montclair

Home renovation in Montclair is different from renovation in newer cities because the houses here were built before modern building codes, before insulation standards, and before anyone imagined a family would still be living in them in 2026. In the Pomona Valley, renovation means opening a 1950s tract home and finding original galvanized plumbing, cloth-wrapped wiring, and framing that was adequate for 1960 but undersized by today’s standards. The climate makes it harder: hot inland summers bake low-pitch roofs, and the clay soil beneath Montclair expands and contracts enough that renovation plans have to account for slab movement before the first wall comes down. Timberline Contractors handles Home Renovation as a full-scope job, not a series of patchwork fixes.
Home Renovation Contractors
Signs you need it
If your Montclair home still has its original galvanized supply lines, ungrounded two-prong outlets, or a roof that predates modern underlayment, renovation is not optional; it is deferred maintenance that is about to come due.
What it costs in Montclair
A full interior home renovation in Montclair typically runs $14,000 to $45,000 depending on scope, with whole-home renovations on older tract homes often landing at the upper end once plumbing and electrical replacement are factored in.
How we do it
We start with a systems audit of the plumbing, electrical, and framing, then sequence the work so mechanical upgrades happen before any finish material goes in, and we pull permits on every phase.
Home Renovation Companies
Signs you need it
When you are comparing multiple contractors and every bid reads differently because nobody has looked inside your walls, you need a renovation company that charges for diagnosis, not guesswork.
What it costs in Montclair
Hiring a full-service renovation company in Montclair rather than trade-by-trade typically lands between $14,000 and $45,000 for a major interior renovation, with the value showing up in a single warranty and a single schedule.
How we do it
We assign a dedicated project lead to every Montclair renovation, bring the brand representatives directly to the project for material selection, and write change orders in plain English before any work changes.
What Home Renovation Costs in Montclair
| Item | Typical range in Montclair |
|---|---|
| Full interior renovation | $14,000 – $45,000 |
| Home addition | $45,000 – $130,000 |
| Garage conversion | $30,000 – $80,000 |
These figures move based on what is behind the drywall. A 1958 Montclair tract home with original systems will cost more to renovate than a house that was updated in the 1990s, because we have to bring the plumbing, electrical, and framing up to code before any new finish goes in.
How long does a full home renovation take in Montclair?
Most full renovations in Montclair run eight to fourteen weeks depending on scope and what the city’s permit desk is processing at the time. Plan on the longer end for jobs that involve foundation work or ADU construction. Call (866) 253-5808 for a realistic timeline on your specific house.
Will my renovation price change once walls are open?
On a 1950s Montclair home, we expect some findings. We build a contingency into the initial estimate and walk you through every discovery with photos and written change orders, so the final number is never a surprise. Call (866) 253-5808 to schedule your free estimate.
Brands We Service in Montclair
We install and service material from a curated list of manufacturers that stand behind their products in this climate: Owens Corning and CertainTeed roofing, Grohe plumbing fixtures, GAF shingles and underlayment, and more. Our brands are chosen for longevity in the Pomona Valley, not for what photographs well in a showroom.

We give you a written, line-item estimate before work starts and we do not change the price unless the scope changes in writing.

What Montclair Customers Say
"Every inspection passed first time. The building department clearly knows him and that made the whole process easier."
— Paul Ackerman"Quality construction and a professional operation. Communication was strongest at the site meetings, and slower by email in between."
— Heather Parker"Excellent build. Costs came in about six percent over the original contract, driven mostly by material price movement during the build, which he documented each time."
— Vivian Nguyen
