Montana Division · Head Office (Montana)

General Contractor in Billings, MT

Our Montana head office. Custom homes, additions, and full mechanical work built for the Yellowstone County climate.

What we build in Billings

  • New Construction

    Custom homes built for Yellowstone County weather — deeper frost footings, impact-rated roofing and tightly sealed, well-insulated envelopes, designed and engineered in-house.

  • Kitchen & Bathroom Remodels

    Bathroom remodels like our Billings marble tub-and-shower project are among the most-requested jobs here; our own crew does the plumbing, electrical, tile and cabinetry.

  • Basement Conversions

    Basement finishing is a staple in Billings, and we handle the egress, moisture and ceiling-height issues that come with it.

  • Additions & Renovations

    Additions tied into existing framing and brought up to current code, with foundation drainage and slab prep sized for the valley's expansive soils.

  • ADUs & Garages

    Detached garages and shops engineered for cold winters, wind off the Rimrocks and summer hail.

  • HVAC, Plumbing, Electrical

    Our crew self-performs plumbing, heating and electrical, which keeps one schedule and one accountable builder on a Billings job.

  • Roofing, Siding, Windows

    Impact-rated roofing and a tight envelope are how we spec every build here, because hail and wind are part of the climate.

  • Pavers & Concrete

    Driveways, walkways and patios placed for Montana freeze-thaw, with base prep and drainage that keep concrete from heaving.

Permits and codes in Billings

Billings permits go through the City of Billings Building Division, with Yellowstone County handling addresses outside the city limits. Our Montana head office is here, so we know both offices' submittal checklists and inspection scheduling and carry the plans through ourselves.

Weather drives the code details in Billings: deeper frost footings, roofing and envelopes specified for cold winters, wind off the Rimrocks and summer hail, and foundation drainage and slab prep that account for the expansive soils found in parts of the Yellowstone Valley. Our in-house engineering and permitting team produces the plans and the structural engineering so the package goes in complete.

Basement finishing, bathroom remodels, additions and detached garages and shops are the bulk of what we build here, and each follows the same path: a permit application with stamped drawings, inspections at foundation, framing, rough-in and final, and a crew that self-performs the plumbing, heating and electrical so there is one schedule to coordinate with the inspector.

Building in Billings: what to know

Billings is our Montana head office, and it's a market where weather drives the details. Cold winters, wind off the Rimrocks, and summer hail mean we spec impact-rated roofing, deeper frost footings, and well-insulated, tightly sealed envelopes on every build. Permits go through the City of Billings Building Division or Yellowstone County for addresses outside the city, and our Montana pricing runs about a third below our Puget Sound baseline because local labor and material costs are lower.

Basement finishing, bathroom remodels like our Billings marble tub-and-shower project, additions, and detached garages and shops are the bulk of what we build here. Soils in parts of the Yellowstone Valley can be expansive, so we pay close attention to foundation drainage and slab prep. Our crew self-performs plumbing, heating, and electrical along with the framing and finish, which keeps one schedule and one accountable builder on a Billings job.

Neighborhoods and nearby cities we serve

From our Montana head office we serve Billings, the Heights, Lockwood and Laurel, and the rest of Yellowstone County. We travel for Montana work farther afield as well — our Missoula bathroom remodel is one example — with crew travel from Billings built into the estimate.

Billings remodeling and building FAQ

Yes. Basement finishes add habitable space and involve egress, electrical and plumbing; detached garages and shops are structures with their own foundations; and bathroom remodels that move plumbing or electrical need a permit too. Permits come from the City of Billings Building Division or Yellowstone County, and we handle the submittal.

A simple remodel permit is usually quick; new homes, additions and detached structures take longer in plan review — generally several weeks to a few months depending on scope and the department's workload. We submit complete, engineered plan sets to keep correction cycles to a minimum.

In most cases, yes — additions and detached garages and shops are a large share of what we build here. Setbacks, lot coverage and soil conditions decide the details, and we check all three on the first visit before design.

Our Montana pricing runs about a third below our Puget Sound baseline because local labor and material costs are lower. The estimate calculator prices your ZIP in about 90 seconds, and the cost guides show typical ranges by state.
