Veteran-Owned. Owner-Operated. On Every Job.

Veteran-owned and owner-operated out of Glendive, Montana — one crew for spray foam insulation, foam roofing, protective coatings, and concrete lifting across MT, WY, ND, and SD.

Who you're calling

Cliff Behner, Owner

A USMC combat veteran who runs the crew the way he was trained: show up on time, do the job to spec, and give people the truth about what their building needs.

We started this company to do insulation and roofing the right way: quality work, straight answers, and pricing you can actually understand. We handle residential and commercial, new construction and existing buildings — from sealing a drafty farmhouse to coating a commercial roof to lifting a sunken driveway. Because we do insulation, roofing, coatings, and concrete lifting in-house, we see the whole building envelope and fix the real problem, not just the symptom. Our diagnostic testing finds where your building is losing air — and whether it's sealed too tight — so you get the right fix, not an upsell.

Serving: Montana, Wyoming, North Dakota & South Dakota

04 / LOCAL

Built for this region

Based in Glendive and working the four-state region — we know cold-weather buildings, metal roofs, and ag structures.

What we do

Our work

INSULATION

Spray Foam Insulation

Open and closed-cell foam that air-seals and insulates in one pass — homes, shops, metal buildings and crawlspaces.

ROOFING

SPF Roofing & Coatings

Seamless spray-foam roofing plus a protective coating for metal and flat roofs — often for less than a tear-off.

COATINGS

Protective & Roof Coatings

Silicone and acrylic coatings that seal seams, reflect the sun, and renew a roof instead of replacing it.

CONCRETE

Concrete Lifting

Sunken slabs, driveways and garage floors lifted back to level with polyurethane foam — no tear-out.
