Exterior paint costs in Boise

Boise summer nights cool off fast, and that's worth knowing before you paint. The gap between the afternoon high and the overnight low averages only about 14 degrees in a Boise January, but more than 30 degrees from July through September. A wall that's warm all afternoon can drop toward the dew point soon after sunset. Benjamin Moore says the painted surface should stay more than 5 degrees above the dew point, so in late summer painters here try to finish early enough for the last coat to dry before evening.

Most of the housing is young: nearly half of it dates from 2000 on. Inside the city limits it's older, with about four in ten homes from before 1980, and on a pre-1978 house in the North End or East End a paid painter has to use lead-safe methods when scraping. A Purdue extension bulletin says one top coat of good acrylic paint should last four to five years and two coats up to ten. So a house from the early 2000s has probably been repainted once already, or is overdue.
