Fast, Reliable General Contractor Across Montclair
Most Montclair homeowners don’t need a handyman. They need a General Contractor who can take a 1950s ranch on an open lot and turn it into what the property should be. That’s what we do at Gold Star Contractors. We handle interior remodels, exterior systems, and detached structures under one accountable team, so you’re not coordinating a framer, a roofer, and a county inspector on your own. Call (833) 382-8544 and we’ll scope your Montclair project properly before a single quote is written.
Montclair’s housing stock is mostly post-WWII tract homes, single-story stucco ranches on slab-on-grade foundations. The lots are bigger than what you’ll find further west, and that changes everything about how a project gets planned. We know the difference between city permitting and San Bernardino County approvals here, because on acreage inside Montclair city limits, both can apply to the same structure.
Why Gold Star Contractors Is Montclair’s Preferred General Contractor Company
We’ve built a reputation in Montclair by quoting honestly and managing the full scope. Led by Noel Carranza, our team coordinates every trade, every brand, and every inspection from the first site walk to the final sign-off. Homeowners here keep calling us back because we understand what older Inland Empire homes actually require once you open the walls.
When a Montclair homeowner calls, we respond. We’re based nearby in Corona, so getting a crew to 91763 isn’t a scheduling problem. More importantly, we already know what we’re likely to find: galvanized plumbing, aluminum wiring, hidden shake layers under newer shingles, and expansive clay that moves slabs. That local knowledge means our quotes reflect the real scope, not a generic number that changes once demo starts.
Our work across Montclair’s neighborhoods, from the older residential streets near Montclair Plaza to the larger parcels east toward Pomona, has taught us which questions to ask before pricing. We don’t skip the soils report conversation on an outbuilding pad. We don’t assume the city owns all the approvals. And we don’t bury haul-distance costs in a lump sum that turns into a change order later.
Styles & brands we work with
Remodeling Contractor in Montclair
Hiring a Remodeling Contractor in Montclair means choosing someone who knows that a 1960s ranch kitchen isn’t a drywall-and-paint job. It’s a full systems replacement: wiring, plumbing, framing corrections, and finishes that meet current code. A kitchen remodel in Montclair typically runs $14,000 – $45,000, depending on whether you’re keeping the original footprint or reworking layout, and a small kitchen remodel lands between $9,000 and $20,000. Cabinet installation alone runs $4,000 – $13,000, and countertop installation $2,000 – $6,500.
We also see plenty of bathroom remodels here. A full bathroom remodel in Montclair runs $9,000 – $28,000, while a smaller bathroom runs $5,000 – $12,000. Walk-in shower installations run $4,500 – $12,000. The older tub surrounds in these tract homes tend to have water damage hiding behind the tile, so we quote with an allowance for substrate repair, not as an afterthought.
Full-Scope Interior Renovation
When the whole house needs work, we manage kitchens, baths, flooring, drywall, trim, and paint through one schedule and one point of accountability. Montclair ranches are straightforward to work in for our crews. We stage material access through the garage or side yard, keep the job site tight on smaller lots, and keep you informed on what we’re finding behind the walls.
Outbuilding and Detached Structure Planning
A detached shop, garage conversion, or ADU on a larger Montclair lot is not the same quote as a tract-home addition. Setbacks, septic placement, well distance, and drainage all move the number. We scope those before quoting so the contract you sign is the price you pay.
Licensed General Contractor in Montclair
A Licensed General Contractor in Montclair carries the full license scope for new construction, remodeling, and renovation. That matters when your project touches structure, not just finish work. Home additions in Montclair run $45,000 – $130,000. A garage conversion runs $30,000 – $80,000. ADU construction runs $90,000 – $220,000. Those are wide ranges because the site conditions drive as much of the cost as the square footage.
On a Montclair acreage property, the license isn’t just about the building itself. It’s about knowing that the septic approval comes from San Bernardino County while the building permit comes from the city. We manage both paths, pull the permits in the right order, and schedule inspections so your draw schedule doesn’t stall mid-rough-in.
Structural and Foundation Work
Expansive clay soils across Montclair mean slabs move. We see cracks, settled patios, and doors that bind. Before we price an addition or a detached structure, we look at the pad, the drainage, and whether a soils report is warranted. Skipping that step saves no one money on an open lot.
Permit and Inspection Management
We pull city permits and county approvals, schedule the inspections, and walk the results with you. When a Montclair project has two agencies involved, that coordination is the difference between a project that moves and one that sits.
Trusted Brands We Service in Montclair
Gold Star Contractors specifies and installs materials from more than 50 vetted manufacturer brands across cabinetry, countertops, roofing, windows, doors, fencing, hardscaping, plumbing fixtures, and prefab structures. For Montclair homeowners, that means you’re choosing from Cambria, Caesarstone, or Silestone countertops; GAF, CertainTeed, or Owens Corning roofing; and James Hardie siding. We also work directly with prefab structure manufacturers including Abodu, Dvele, and Mighty Buildings for ADUs and detached structures. These are real material choices with real installation standards, not generic contractor-grade substitutes. We specify the brand, manage the install, and stand behind the result.

AfterCommon General Contractor Problems We See in Montclair Homes
- Hidden shake layers under newer shingles. Many of the original 1950s-60s tract homes near Montclair Plaza and the older residential streets still have wood shake roofs buried under later shingle layers. Re-roofing uncovers it, and disposal adds days and cost to the haul schedule. We quote it as a line-item allowance, not a lump sum surprise.
- Expansive clay moving slabs and pads. Montclair sits on clay that swells when wet and contracts when dry. The summer heat, with temperatures regularly over 100°F, makes it worse. Any outbuilding pad, driveway, or addition needs a drainage plan before concrete is poured.
- Aluminum wiring and galvanized plumbing. Mid-century tract homes in Montclair were built with materials that are now at end of life. Any remodel that opens walls should expect to replace them, not hope they’re fine. Our quotes include the reality.
- Two approval tracks on acreage properties. In most cities, one permit office handles everything. In Montclair, a detached ADU or outbuilding can trigger city building review plus San Bernardino County septic, well, and grading approvals. Contractors who don’t know that miss it in the quote, and you find out at the first inspection.
Pricing for General Contractor in Montclair, CA
Pricing in Montclair is driven by property type more than square footage alone. A tract-home kitchen remodel runs one range. A detached shop with septic and well setbacks on an open lot runs another. Here’s what we see across the city for the projects that touch structure:
| Project | Typical Range |
|---|---|
| ADU Construction | $90,000 – $220,000 |
| Garage Conversion | $30,000 – $80,000 |
| Home Addition | $45,000 – $130,000 |
The range depends on whether the county signs off on your septic and well setbacks without additional engineering, what the soils report says about the pad, and how far material deliveries have to travel across the lot. We write a line-item quote so you see exactly what each permit path, each haul, and each allowance costs. Schedule your free estimate by calling (833) 382-8544.

FAQs About General Contractor in Montclair
Both can apply. Montclair is one of the few Inland Empire cities where an acreage property can sit inside city limits while the septic, well, and grading approvals run through San Bernardino County. So a detached shop or ADU here is a two-permit-agency job, not one. We manage the city building permit and the county approvals in the correct sequence, which keeps the project moving and the inspection schedule clear. Call (833) 382-8544 and we’ll tell you which approvals your specific property triggers.
Because a large share of the original 1950s-60s ranches near Montclair Plaza and along the older residential streets still have wood shake roofs hidden under subsequent shingle layers. When we tear off, we find the shake, and disposal costs and haul days go up. Our crew built a detached shop-and-ADU pad on an open lot near Montclair Plaza a few years back, and the discovery under the demo was three layers of shingle over original wood shake. Disposal alone added days to the haul schedule. We quote that as a line-item allowance so it doesn’t become a change order. Call (833) 382-8544 for a re-roof quote that accounts for what’s actually under your current roof.
They add engineering and drainage scope. Montclair’s clay soils swell and shrink with moisture, and the hot, dry summers with Santa Ana wind events make that movement worse. On an outbuilding pad or addition, we often recommend a soils report before concrete. We then engineer the drainage to move water off the pad, which changes the grading number but protects the structure. That’s line-itemed, not buried. Call (833) 382-8544 to walk through what your lot needs.
A line-item quote that names the unknowns before work starts. Hidden shake layers, expansive clay, old wiring, county setbacks, haul distance: we list each as an allowance with a stated number. Then, if the condition appears during demo, you already know what it costs. The change order is already priced. Noel Carranza’s team walks every Montclair project this way because it’s the only honest way to bid an older home. Call (833) 382-8544 for a quote written that way.
Yes. We pull the city building permit for the structure and the San Bernardino County approvals for septic, well, and grading when they apply. We schedule the inspections in the right order, meet the inspectors on site, and document the sign-offs. You get one point of contact for both approval tracks. Call (833) 382-8544 for a free estimate on any Montclair acreage project.
