Why Elmstead Remodeling Is Montclair’s Preferred General Contractor Company

We’ve worked on enough Montclair homes to know what waits behind the stucco of a 1960s ranch. The cloth-wrapped wiring, the chimneys with no seismic anchorage, the slabs that need engineered footings because the alluvial soils shift from gravel to silt mid-lot. Our General Contractor team doesn’t guess at what’s inside your walls. We inspect first, write allowances into the contract, and price any surprise in writing before we touch it.
Graham Stein leads our operations with a straightforward rule: the crew that walks through your door wears shoe covers, lays drop cloths before touching anything, and asks before moving furniture or pet bowls. Every technician is background-checked and uniformed. Phones are answered by a live person 24/7, not a voicemail box, not a bot. Our 365-Day Done Right Promise covers every completed project. If it’s not done right, we make it right. That’s the longest-standing post-project commitment in our service area.
Styles & brands we work with







Construction Company in Montclair
Construction Company work in Montclair means building on some of the most geologically complex residential ground in the Inland Empire. Because Montclair sits on deep alluvial fan deposits directly south of the Cucamonga Fault, virtually every ground-up build or significant addition triggers San Bernardino County seismic zone requirements. The alluvial material can shift from dense gravel to soft silt within the same lot. Standard prescriptive footing depths are routinely rejected without a licensed geotechnical engineer’s sign-off. This isn’t a bureaucratic hurdle. It’s a real condition that affects how we price and schedule your project from day one.
When a Montclair homeowner calls us for a room addition, home addition, or ADU construction, we build the soils report and engineered footings into the initial scope. No guesswork. A typical home addition in Montclair runs $45,000 – $130,000. ADU construction runs $90,000 – $220,000. Concrete driveway installation, a common companion project for homes with cracked or settled slabs, runs $4,500 – $12,000.
Engineered Foundations for Alluvial Soils
We don’t pour footings until a licensed geotechnical engineer has characterized your lot. The inspector signs off on the first pass because we did the homework. This adds time and cost upfront. It prevents permit kickbacks and foundation failures later.
Title 24 Compliance in High Heat Zones
Montclair’s inland valley position produces summer highs regularly exceeding 100°F. Title 24 energy compliance for new construction and permitted additions is notably demanding here. We calculate cooling loads precisely and specify insulation, window, and HVAC upgrades that pass inspection without rework.
Remodeling Contractor in Montclair

Remodeling Contractor work in Montclair is almost always renovation of 1950s – 1970s post-WWII tract housing: modest single-story stucco homes on slab-on-grade foundations that predate modern seismic, accessibility, and Title 24 energy codes. The bulk of these neighborhoods, from the streets near Montclair Plaza to the older tracts off Ramona Avenue, share the same underlying conditions. We regularly open walls and find cloth-wrapped wiring, unreinforced masonry chimneys, and underinsulated wall assemblies that must be brought into compliance with current California Building Code once a permit is pulled.
A kitchen remodel in Montclair typically runs $14,000 – $45,000. A small kitchen remodel runs $9,000 – $20,000. Bathroom remodels run $9,000 – $28,000, with small bathrooms at $5,000 – $12,000. These ranges include the code upgrades we almost always encounter. We don’t lowball the initial quote and surprise you later.
Written Allowances for What We Can’t See
We inspect behind stucco where accessible before writing your contract. Where we can’t see, we list specific dollar allowances for common Montclair conditions: framing repair, electrical upgrade, chimney seismic anchorage. If we don’t use them, you don’t pay. If we do, the price was already in your hands.
Quiet Tools and Pet-Safe Products
Families with children and pets are our typical Montclair customer. We run quiet tools during nap and school hours where possible. We choose pet-safe products where a choice exists. The crew photographs the clean-up before leaving. Shoe covers and drop cloths are on every visit, included, never charged extra.
Trusted Brands We Service in Montclair
We specify named-brand materials on every Montclair project so homeowners can research warranties independently and know exactly what they’re getting. Cabinetry comes from KraftMaid and Wellborn. Countertops from Cambria, Silestone, and Caesarstone. Fixtures from Kohler, Moen, and Grohe. Exterior cladding from James Hardie, roofing from GAF. For ADU and modular projects, we also work with Abodu, Cover, Dvele, and Mighty Buildings. These aren’t placeholder names. They’re the products we order, the warranties that travel with your finished project, and the brands our Montclair customers ask for by name when they’ve done their homework.

AfterCommon General Contractor Problems We See in Montclair Homes
- Cloth-wrapped wiring behind intact stucco. We opened a 1958 slab-on-grade ranch in the Monterrey Park tract near Holt Blvd to combine two rooms, and the moment the stucco came off we found cloth-wrapped wiring that had to be replaced before any framing could proceed. We stopped, wrote the electrical upgrade into a change order, and had it signed before touching a wire.
- Unreinforced masonry chimneys with zero seismic anchorage. Montclair’s position on the Cucamonga Fault means these chimneys are a genuine hazard. Bringing them to code during a remodel isn’t optional once walls are open and a permit is active. We build this allowance into contracts for homes of the right era.
- Subfloors sistered with non-load-bearing lumber. On that same Holt Blvd project, we found a subfloor that had been sistered twice with lumber that couldn’t carry the load. Our tech replaced it with engineered footings sized to the licensed geotech’s report, and the inspector signed off on the first pass.
- Failed waterproofing in original slab-on-grade construction. Montclair’s intense Santa Ana wind events and thermal cycling degrade exterior stucco and caulking faster than coastal cities. Once we open walls, we often find moisture damage that requires remediation before insulation and drywall can go back.
