Window Replacement
in Post Falls, ID

Post Falls grew from about 7,300 people in 1990 to more than 38,000 in 2020, and most of the housing arrived during that run. That gives the city an unusual window problem for North Idaho. The issue here is rarely a drafty hundred-year-old sash. It is builder-grade vinyl from the 1990s and 2000s that has now reached 20 to 30 years old, where the seal has failed, the argon has escaped, and the glass fogs from the inside where no amount of cleaning will reach.

At 2,202 feet on the edge of the Rathdrum Prairie, Post Falls gets long cold snaps, real snow, and bright dry summers. That annual swing is exactly what finishes off a tired insulated glass unit. We match low-E coatings and gas fills to a continental climate rather than a coastal one, use warm-edge spacers so the edge of the glass is not the cold spot, and flash every opening so wind-driven snow stays out of the wall assembly.

Local considerations in Post Falls

Because so much of Post Falls went up after 1990, most homes here still have their original windows, and they tend to fail as a group rather than one at a time. Whole subdivisions off Highway 41, through Prairie Falls and along the river reached the same age together. The practical result is that a Post Falls project is usually a whole-house replacement rather than a single repair, and pricing a full house at once costs less per opening than replacing them piecemeal over several years. Post Falls also sits in Kootenai County, so permits and inspections run through the City of Post Falls Building Department rather than any Washington jurisdiction.

Learn About Our Window Installation Method

A window performs the way it was installed. Ours is sealed, shimmed square, and flashed so water that gets past the trim has a way back out rather than a way into the wall.

We also offer the patented Rain Jacket Flashing System, developed by 2FL, which passes the AAMA pressure tests for water and air penetration required on condominium work and holds against 120 MPH wind-driven rain.
