Why Polaris Contractors Is Montclair’s Preferred General Contractor Team

Montclair homeowners appreciate that we show up knowing the difference between a 1956 tract home on the west side and a mid-century apartment conversion near the 10 freeway. That matters when you’re pricing a remodel, because those two job sites come with completely different staging and permitting realities. Rick Sondermann leads our Montclair CWS service crew, and he’s spent years navigating the small-city permit process in communities exactly like Montclair, where every square foot of lot counts. We’re licensed and insured, and we write allowances into contracts so surprises get priced in writing, not sprung on you after demo. The reviews we get from Montclair customers most often mention the same thing: we explain what a change order means before it happens, and we don’t disappear when the building inspector has notes.

One team handles it all. Our General Contractor crew manages structural framing, roofing, windows, kitchens, baths, fencing, and hardscaping under a single agreement. That eliminates the finger-pointing you get when a plumber blames the electrician and nobody owns the schedule. When you work with us in Montclair, you’re hiring accountability, not a rotating cast of subcontractors.

Remodeling Contractor in Montclair

A remodeling contractor in Montclair does more than swap finishes. On most of these 1950s and 60s tract homes, a remodel means opening walls and confronting whatever the original builder left behind: galvanized plumbing, ungrounded wiring, undersized headers, and framing that was never meant to span an open-concept kitchen. A kitchen remodel in Montclair typically runs $14,000 – $45,000, and much of that range depends on what the inspection uncovers once the drywall is down. We inspect first, write allowances into the contract, and get written approval before any extra work starts.

Kitchen and Bath Rehabs on Older Homes

Most Montclair remodels start with the kitchen or bathroom because those spaces show age first. We specify materials that hold up to the dry inland heat and daily use, from Schluter waterproofing systems in showers to Grohe fixtures that don’t corrode like the original 1960s hardware. You get a line-item quote before work starts, not a vague number that drifts upward.

Structural Changes Hidden by a Cosmetic Remodel

Removing a wall between a Montclair kitchen and living room often triggers a load-bearing correction. We handle the engineering review, pull the permit, and schedule the inspection sign-off. Our team coordinates framing, electrical, plumbing, and finish work so the project advances without you having to chase down trades.

Licensed General Contractor in Montclair

A licensed general contractor in Montclair carries the liability and the permit responsibility, not you. When your project requires structural changes, a new roofline, or a garage conversion, the city wants a licensed operator on file. We hold that license and we’ve been through Montclair’s plan-check process enough to know which details need attention before submission. A home addition in Montclair typically runs $45,000 – $130,000, and an ADU construction project lands between $90,000 – $220,000. Those numbers assume completed work with permits pulled and inspections passed.

Permit-Triggered Code Upgrades

Opening a wall in a 1950s home triggers code requirements the original build never met. We plan for GFCI outlets, hardwired smoke detectors, and upgraded circuit capacity from the first walkthrough. That way the inspector’s notes don’t become a panic at rough-in.

Garage Conversions and ADUs on Tight Lots

Montclair’s fully built-out blocks leave little room for equipment access. A garage conversion in Montclair runs $30,000 – $80,000 and requires staging from the street or alley, hand-carry deliveries, and careful sequencing. We plan that logistics chain before demo day, which keeps neighbors happy and the project moving.

Trusted Brands We Service in Montclair

We stock and install materials from brands that hold up in Montclair’s dry heat and occasional Santa Ana winds. For roofing, we work extensively with GAF systems, specifying warranty tiers that make sense for inland sun exposure. In bathrooms and kitchens, we install Schluter waterproofing and Grohe fixtures, brands our Montclair clients ask for specifically because they know they’ll last. If you want Sterling tubs or fixtures as a solid mid-market option, we can spec those too. We don’t push one brand; we guide you to what fits your home and budget.

Common General Contractor Problems We See in Montclair Homes

  • Tight-lot staging delays: Builders in the 1950s didn’t leave room for a dumpster and a delivery truck. We plan for hand-carry or crane deliveries from the street or alley before work starts, so your remodel doesn’t stall waiting for access.
  • Original galvanized plumbing and outdated wiring: Most Montclair homes still have the original supply lines and ungrounded circuits. We write plumbing and electrical allowances into the contract so those upgrades don’t become surprise change orders mid-project.
  • Undersized framing in load-bearing walls: Powder-actuated framing and lead headers fail current code once a wall is opened. We inspect before quoting so the structural correction is in the budget, not added later.
  • Failed waterproofing and exterior seal failures: Years of 100-degree summers and wind-driven rain degrade shower pans and window flashing. We address waterproofing at the source, not with a cosmetic patch.

What Montclair Customers Say

Trusted by homeowners across Montclair and surrounding areas.

★★★★★

"He was upfront about a soil issue that added cost early rather than absorbing it and surprising us at the end."

Brandon Lin · Verified customer

Cedric Dawson · Verified customer
★★★★★

"Ground up build. Permits, foundation, framing, all of it, and he ran the schedule tightly enough that the subs were never tripping over each other. Finished within a month of a fourteen month estimate."
