Build your home from the ground up

When dealing with drafty windows or doors that no longer seal properly in Whitefish, the problem is rarely just old glass—it's frame deterioration, failed weatherstripping, compromised rough opening framing, and glazing systems that weren't rated for extended sub-zero exposure. Pronghorn Contracting LLC installs replacement windows and exterior doors across the Whitefish area, addressing the full rough opening, not just the visible unit. Every installation includes proper shimming, flashing tape integration, and air sealing at the rough opening perimeter before trim is applied.

Whitefish properties near Whitefish Lake and along US-93 experience sustained cold periods where thermal bridging through window frames accounts for a significant portion of a home's heat loss. Single-pane units and older double-pane windows with failed seals create visible condensation between panes, frost formation at sill corners, and consistent cold radiation that makes rooms uncomfortable regardless of heating output. Replacing those units with triple-pane or high-performance double-pane windows rated for cold climates reduces heating demand and eliminates condensation at the glass surface.

Whether you're replacing a single failing unit or upgrading all windows and exterior doors in a Whitefish home, the installation sequence and rough opening preparation determine how the replacement performs over the next 20 years.
