Kalispell carries the most varied inventory in the valley. Older homes near the core, many built well before attic air sealing was standard practice, sit alongside mid-century ranches, 1970s and 1980s subdivisions, and a substantial volume of newer construction driven by regional growth.
That variety drives what we get called for. On the older end, we are usually addressing attics that carry a fraction of current recommendations, uninsulated rim joists, and vented crawl spaces making the floors above them cold.
On the newer end, we are working with builders at the specification stage on whole-envelope packages. Both are common here and neither is unusual.
