Fast, Reliable Home Remodeling Across Montclair
Home remodeling in Montclair usually costs between $14,000 and $45,000 for a full kitchen, $9,000 to $28,000 for a bathroom, and $45,000 to $130,000 for a home addition. Those are realistic numbers for this specific market, and they’re the ranges we quote from when we walk your property. Gold Star Contractors has remodeled homes throughout the 91763 ZIP code long enough to know that Montclair’s 1950s and 60s tract houses present challenges newer neighborhoods just don’t — experience that makes us a trusted PGT in Montclair choice. If you’re planning any kind of remodel here, call (833) 382-8544 and we’ll give you an honest, line-item estimate based on what’s actually behind your walls.
Why Gold Star Contractors Is Montclair’s Preferred Home Remodeling Company
Montclair homeowners keep calling us back because we handle the full scope under one roof. Most remodelers want to do your kitchen, then hand you off to someone else for the structural work. We don’t. Our Home Remodeling team handles carpentry, plumbing, electrical, cabinetry, countertops, flooring, and the structural side of the job without handoff gaps. When you’re working on a 60-year-old ranch near Central Ave, that coordination is the difference between a project that passes inspection the first time and one that stalls for weeks.
Noel Carranza has built Gold Star Contractors around one principle: the person who scopes the job should be accountable for the finished product. That accountability matters more in Montclair than in newer Inland Empire cities because the housing stock here hides real surprises. We know to check for original wood shake roofs under shingle layers, we understand how expansive clay soil moves under a slab foundation, and we plan for both before we hand you a number. Our Montclair customers regularly tell us that our bids are the only ones that accounted for what the inspector actually flagged.

Full Home Remodel in Montclair
A Full Home Remodel in Montclair means gutting and rebuilding the major living spaces of a post-war tract home while keeping the existing foundation and roofline in place. Here, that almost always means working around slab-on-grade foundations, original 1950s plumbing, and plaster walls that have been patched for six decades. We’ve completed full remodels on homes near Montclair Plaza where the kitchen, both bathrooms, and flooring all needed to work around structural repairs first.
On a ranch-style home near Montclair Plaza, we opened up a kitchen wall and found the original 1950s wood shake roof under three layers of shingles. That forced a change order for tear-off and disposal before any cabinetry could go in. We also addressed the expansive clay soil by reinforcing the slab-on-grade foundation before installing new KraftMaid cabinets. The project passed inspection with a detailed punch list, and the homeowner appreciated the transparent draw schedule that accounted for the unforeseen structural work.
Full remodels in Montclair typically run $45,000 to $130,000 depending on square footage, material grades, and what we find once the drywall comes down. We quote that range by line item so you can see exactly where the money goes. Call (833) 382-8544 to have us walk your property first.
Structural Work Before Finish Work
On Montclair’s slab-on-grade homes, you don’t install $14,000 in kitchen cabinetry on a slab that’s moving. We evaluate the foundation for expansive clay soil damage before a single finish trade shows up. If the slab needs reinforcement, that gets scoped and priced before you ever choose a countertop.
Material Selection With No Change Orders
Because we work with more than 50 manufacturer brands – KraftMaid and Wellborn for cabinetry, Cambria and Silestone for counters, Kohler and Grohe for fixtures – you pick what you actually want, not what one supplier has in stock. We price every selection in the original quote so the number you sign stays the number you pay.
Home Remodeling Contractor in Montclair
A Home Remodeling Contractor in Montclair needs to be more than a project manager with a truck. The best ones here understand that a 1958 stucco ranch on Holt Blvd is not the same as a 1990s build in Ontario. You need someone who knows where the original galvanized plumbing runs, why the wiring might need replacement, and how to pull the right permits without wasting three extra weeks.
Gold Star Contractors is a licensed general contractor with full scope across interior and exterior systems. That means we handle the kitchen remodel and the roof work, the bathroom and the fencing, the flooring and the structural repair – all on one contract, one schedule, and one point of accountability. Noel Carranza reviews every Montclair scope personally before we quote it, because this city’s older housing stock doesn’t respond well to generic bids.
Window replacement in Montclair runs $4,500 to $15,000. A tub-to-shower conversion runs $3,500 to $10,000. We know these numbers because we’ve done them here, repeatedly, on the same floor plans you live in. Call (833) 382-8544 for a free estimate that reflects actual Montclair conditions, not a national average.
Permit Coordination Done Right
Montclair permitting is straightforward for interior work, but anything structural, electrical, or plumbing-related needs sign-off. We pull the permits, schedule the inspections, and walk the inspector through the work ourselves. You don’t stand in line at City Hall unless you want to.
One Team, Every Trade
Instead of juggling a separate plumber, electrician, framer, and finish carpenter, you get one project team that has already worked together on dozens of Montclair homes. The tile setter knows the cabinet installer. The electrician knows the plumber. The schedule holds because the team holds.
Trusted Brands We Service in Montclair
Montclair customers don’t want a contractor who pushes one cabinet brand because that’s the only rep who returns his calls. You want actual choice. We’re set up that way. Our brand partnerships include KraftMaid and Wellborn for cabinetry, Cambria, Caesarstone, and Silestone for countertops, plus Kohler and Grohe for plumbing fixtures. We also work with prefab and modular manufacturers like Dvele and Mighty Buildings when you’re planning a detached ADU or outbuilding on a larger Montclair lot. Because we carry these relationships, we can typically get materials to Montclair job sites faster than a contractor placing one-off orders. Call (833) 382-8544 and we’ll show you material samples at your kitchen table, not a showroom across the county.

AfterCommon Home Remodeling Problems We See in Montclair Homes
- Hidden wood shake roofs under later shingle layers. Many original 1950s-60s tract homes along Holt Blvd and Central Ave still carry the original wood shake roof beneath two or three layers of shingles. That discovery adds tear-off and disposal cost, and sometimes triggers structural roof repairs before interior work can proceed.
- Expansive clay soil under slab foundations. Montclair’s soil expands and contracts with moisture, and that movement cracks tile, separates countertops from walls, and shifts door frames. We evaluate slab condition before installing any finish materials so a new kitchen floor doesn’t crack within a year.
- Original galvanized plumbing and aluminum wiring. Homes built between 1950 and 1970 in Montclair often still have original galvanized supply lines and older aluminum branch wiring. Both are functional until they’re not, and both should be scoped into any remodel that opens walls.
- Permit failures on detached structures. Acreage lots in Montclair sometimes have unpermitted outbuildings or older additions. When you want to build a detached ADU or shop, county setbacks for septic and well systems have to be verified before any structure is designed. We handle that before you spend a dollar on plans.

FAQs About Home Remodeling in Montclair
Montclair city permits cover most interior remodels, but a detached ADU or outbuilding on a larger lot often requires county-level clearance for zoning, septic, and well setbacks before the city will process your building permit. We handle both levels. The first step is a site evaluation to confirm where your existing septic and well lines sit, which drives the ADU footprint and the price. Call (833) 382-8544 and we’ll pull the right permits from the start.
Expansive clay soil in Montclair expands when wet and shrinks when dry, and that cycle moves slab-on-grade foundations over time. For a home addition, that means your foundation design has to account for soil movement – typically deeper footings and sometimes soil treatment before concrete is poured. For an interior remodel, it means we reinforce and level the existing slab before tile, cabinetry, or flooring goes down. Skipping this step is how new tile cracks within a year. Call (833) 382-8544 for a foundation evaluation as part of your free estimate.
Expect a change order for tear-off and disposal, plus possible structural roof repair before interior work resumes. We’ve found this on Montclair homes near the Plaza where multiple shingle layers hide the original 1950s wood shake roof. The added cost typically runs a few thousand dollars depending on square footage and whether the underlying sheathing needs replacement. We scope this as a contingency line in our Montclair bids so it doesn’t blindside you. Call (833) 382-8544 and ask us to check your roofline during the estimate.
Yes. Well and septic setbacks control where any detached structure can sit on your property, and we survey those lines before we design anything. This matters most for shops, outbuildings, and detached ADUs on larger Montclair lots where the county requires minimum distances between a structure and your septic tank, leach field, and wellhead. We build the structure around those constraints, not the other way around. Call (833) 382-8544 to have us map your setbacks as part of the scoping process.
We schedule material deliveries and equipment drops so they don’t tear up your driveway or landscaping, and we coordinate with the manufacturer delivery windows directly. On acreage lots where space isn’t the issue but distance is, we stage materials in phases so the job site stays organized. For tight access on older streets near Holt Blvd, we arrange smaller, more frequent deliveries rather than one massive drop. Call (833) 382-8544 and we’ll plan your delivery logistics before work starts.
