Windows in Idaho fail one way in a wet northern valley and another on a dry windy plain. Soft sills and ice on the glass are the timber report. Whistles, grit in the tracks, and a racked sash are the foothill report. West sun cooks the trim while the night goes cold. Count the bad elevation before the whole house becomes one order.
Log, brick, and thick older walls change the install, and a full-frame opening may not be square. Insert work is a mistake if the sill is soft. Feel the wood before you choose. Storm panels are an honest repair when the glass is intact and the sill is dry. A meeting rail that misses on a foothill night will not be cured by a bead of sealant.
Ask how the sill sheds water and what fills a deep gap. A new unit on a punky sill repeats the stain. South glass takes a hard sun and a hard night, and that swing fogs the panes and checks the trim. Ask for whole-unit specs, not a promise the house will use less of anything. You want the windward rooms usable and the stool dry.
Cabins closed for a stretch reveal the worst sills when they are opened. Full-time houses show the failure all winter as ice and a room the heat cannot catch. Inversions and seasonal smoke make people tape over drafts instead of fixing the sash, and the tape does not survive the next foothill gust. Say which life the building has. If a claim is open, photograph the bad elevation before anyone paints the trim.
Say how many openings, which rooms, and whether the sills are soft. Name the town and which way the bad wall faces the wind or the sun. Have the deductible only if the policy is already part of this. The next freeze will put water back on the glass, and a foothill gust will find the same rail. Call the number on this page.
