Fast, Reliable General Contractor Across Montclair
If you’re planning a remodel, addition, or ADU in Montclair, you need a general contractor who understands what this city’s building stock actually demands. Square Deal Contractors manages every phase of the work, from the first engineering review to the final inspection sign-off, so you’re not coordinating a roofer, a framer, and a finish carpenter on your own. We work throughout ZIP 91763, and we’re familiar with the 1950s to 1970s ranch homes and the narrow-lot conditions that shape nearly every project here. Call (866) 623-7205 to schedule a free estimate.
Why Square Deal Contractors Is Montclair’s Preferred General Contractor Company
Montclair homeowners keep running into the same problem with Montclair CWS service: they get three different bids from three different specialists for one project, and nobody takes responsibility for what happens in between. That’s the gap we close. One contract, one point of accountability, every phase from roofline to backyard. Nolan Breckett built this company around a simple operating rule: we tell you exactly what you’re getting and why, and the estimate you approve is the scope we build.
Our General Contractor team has worked on homes from the north end near the 10 freeway down to the neighborhoods south of the 60, and on infill projects along Holt and Arrow corridors. The local work we do is almost entirely renovation, addition, and ADU construction on already-occupied parcels, which means we’re used to tight side yards, mature street trees, and older utility laterals that a tract builder never touches. When permits stall in Montclair, they usually stall on setback and drainage compliance, not on framing. We plan for that from the first site visit.
When a Montclair homeowner calls us, they’re speaking with someone who knows the difference between a 1960s wood-frame ranch that needs shear-wall hold-downs and a 1980s build that can accept a simpler retrofit. That local knowledge cuts plan-check delays and keeps the project moving.
Styles & brands we work with
Licensed General Contractor in Montclair
Licensed General Contractor work in Montclair means managing the structural, mechanical, electrical, plumbing, and finish phases of a residential build under a single contract, with permits pulled and inspections passed. A homeowner typically calls us when a project crosses trade lines: you’re adding a bathroom that requires new DWV lines, opening a load-bearing wall, or building an ADU that needs its own service panel. Kitchen remodels in Montclair run $14,000 to $45,000, bathroom remodels $9,000 to $28,000, and a full home addition starts at $45,000 and can reach $130,000 depending on square footage and structural scope.
Permit and Inspection Management
We pull the permits, schedule the inspections, and stand on-site with the inspector until the work is signed off. On Montclair projects that require wind-load engineering, we submit the engineering letter with the permit application rather than waiting for a plan-check correction, which keeps the schedule from stretching into extra months.
Fixed-Scope Contracts
The price we quote is the price we build, with line items for labor, materials, permits, and engineering. If the inspector requires a change, we document it and explain the delta before any new work begins. No runaround, no surprise invoices.
Residential General Contractor in Montclair
Residential General Contractor services in Montclair cover the full range of home construction, from a tub-to-shower conversion to a ground-up ADU in a rear yard. Because the city is nearly 100 percent built out, most of what we do is infill: second-story additions over existing ranch homes, garage conversions along the Holt corridor, and ADUs set tight to property lines behind existing block walls. A garage conversion typically runs $30,000 to $80,000, and ADU construction runs $90,000 to $220,000, with engineering, permit fees, and site work included in the scope.
Wind-Load Engineering for Additions
Almost every second-story addition or ADU in Montclair must be engineered for Santa Ana wind uplift. That means roof diaphragm design, shear-wall hold-downs, and a continuous load path from roof to foundation, all documented and inspected. A cheap quote that omits the engineering letter will sit in plan check for months, and the work cannot legally be occupied without the sign-off.
Site Work on Narrow Lots
On a 1950s ranch off Holt Boulevard, our crew built a rear-yard ADU tight to the block wall; we engineered the roof diaphragm and shear walls to resist Santa Ana wind uplift, pulled the permits, and walked the inspector through every hold-down before the drywall went up. The owner later used our stamped inspection sign-off to document compliance for an insurance discount.
Trusted Brands We Service in Montclair
The materials on a Montclair project matter, because they have to stand up to Pomona Valley heat, dry winds, and the occasional heavy winter rain. We source from a vetted portfolio of more than 50 manufacturers so we can match the material to the actual budget and the actual load requirements. For roofing on Montclair homes, we regularly install GAF and Owens Corning systems, including wind-rated shingle lines that meet the uplift requirements for Santa Ana wind zones. For kitchens and baths, Grohe fixtures carry the flow and finish quality that hold up over decades. The right material for your project and your budget, not whatever a single supplier happens to push.

AfterCommon General Contractor Problems We See in Montclair Homes
- Missing wind-load engineering on ADU or second-story roofs. The permit goes in, plan check flags it, and the project stalls for eight to twelve weeks while a letter gets drafted. We submit the engineering up front, as part of the permit package.
- Shear-wall hold-downs left out of the scope of work. The rough-in inspection fails because the continuous load path was never detailed. The homeowner then pays for retrofit engineering and re-framing. We spec every hold-down, strap, and anchor before demolition starts.
- Low bids that exclude permits and inspection sign-off. A homeowner approves a cheap quote for an ADU, then discovers mid-project that the building cannot legally be occupied until someone pulls permits and passes inspections. That work isn’t optional; it should be in the contract from day one.
- Cracked stucco and drywall movement in older wood-frame homes. Montclair’s 1950s and 1960s homes are prone to drying and shifting from inland heat cycles. When we open a wall, we check the loading, and if the framing needs shear reinforcement, we say so before covering it back up.

What moves a Montclair project from the bottom to the top of those ranges is structural scope and site conditions. A kitchen in a 1965 ranch that needs a beam where a wall comes out costs more than a cabinet-and-countertop refresh. An ADU on a narrow lot with poor drainage needs more engineering and grading than one on a level, open yard. Every estimate we write is line-itemed so you can see what the engineering, permits, materials, and labor actually cost. Call (866) 623-7205 for an exact quote, and we’ll put it in writing with no change orders unless you request a change.

FAQs About General Contractor in Montclair
A new ADU or second-story addition in Montclair typically must be engineered for Santa Ana wind uplift pressures that are specific to the inland valley exposure; the design wind speed and exposure category are determined by the structural engineer and submitted with the permit package, and the work must show a continuous load path from roof to foundation. That means hold-downs, straps, and shear walls, not just extra nails. Call (866) 623-7205 and we’ll review your lot and building department requirements before you commit to a set of plans.
Yes, a legitimate Montclair addition quote must include permit fees, engineering, and scheduled inspections through final sign-off, because a structure built without documented sign-off cannot legally be occupied and will not hold up against an insurance claim. If a bid leaves those out, you will pay for them later. Our estimates are line-itemed so you see exactly what compliance costs.
Documented wind-load compliance gives your insurer evidence that the structure was built or reinforced to current code, which can support lower premiums or faster claim approval after a wind event; the stamped engineering letter and passed inspection record are the documents that carry the weight. We provide those documents to every Montclair client at close-out. Call (866) 623-7205 to ask about your specific project.
The scope of work for an ADU on a narrow Montclair lot should include site grading and drainage, setback compliance, structural engineering for wind uplift, shear-wall hold-downs, utility connections, and inspection scheduling through final sign-off; if any of those line items are missing, the quote is incomplete. We write every narrow-lot ADU scope with those items as separate lines so you can see the real cost before you sign.
Montclair permits often take longer because the city is nearly fully built out, so plan check gets locked up on setback, drainage, and wind-load engineering for infill projects rather than on the framing itself; a complete engineering package submitted with the initial application reduces most of that delay. We submit complete packages the first time. Call (866) 623-7205 for a free estimate and we’ll walk you through the timeline for your specific project.
