FAQ

Frequently asked questions.

The questions we hear most often on consultation calls. Don't see yours? Call us at (406) 544-4492.

How long does a custom home build take in Western Montana?

Most custom home builds in Western Montana take 9–14 months from breaking ground to keys-in-hand. Foundation through dry-in (framing + roof + windows) typically runs 3–4 months. Interior work — drywall, trim, finishes — runs another 5–8 months. Weather and material lead times affect timing more than anything else. We give you a realistic schedule at the start and update you weekly.

Do you handle permitting and inspections?

Yes. We pull all permits, schedule inspections, and meet inspectors on site. You shouldn't have to learn the Missoula County or City permitting process to build your house — that's our job.

What's the average cost per square foot to build in Missoula?

Custom builds in the Missoula area generally run $250–$450 per square foot in 2026, depending on finishes, site conditions, and structural complexity. Production-style builds can come in lower; high-end custom with premium finishes runs higher. We give you a fixed-bid line-item quote so there are no mid-project surprises.

Do you work in winter?

Yes. Framing and exterior work slow down or pause when temperatures drop, but interior trim, tile, and finish work continue year-round. We sequence projects so the dry-in (roof and walls closed up) happens before deep winter, then we work inside through the cold months.

What's included in the free consultation?

A real conversation. On-site if you're nearby, video call if not. We listen to what you want, look at your site if you have one, and tell you honestly whether your project fits what we do, what realistic budget looks like, and what we'd recommend for next steps. No pressure, no contracts, no obligation.

How far do you travel for jobs?

We work throughout Western Montana — Missoula, the Bitterroot Valley (Hamilton, Stevensville, Florence), Seeley Lake, the Flathead area (Kalispell), Polson, and surrounding communities. If you're in the (406) and not on this list, ask. We may still be a fit depending on the project.

Are you licensed and insured?

Yes. We're a licensed Montana general contractor, fully insured, and bonded. Documentation available on request.

What's your warranty policy?

One-year workmanship warranty on everything we build. Manufacturer warranties on materials (roofing, siding, etc.) typically run longer — we register those for you. If something goes wrong, we answer the phone.
