Daylight at the entry door: seals, sweeps, and self-closing

Stand inside a unit on a bright day, lights off, and look at the entry door frame. A ribbon of daylight tells you three things at once: the weather seal has failed, heated air is leaving all winter, and on a fire-labeled door the seal and self-closing action are part of what the label promises. Fire-labeled doors are one of the affirmative requirements that began deducting points on October 1, 2026, which makes the door check worth doing slowly: door closes and latches on its own from open, no daylight past the seals, hardware tight. Two minutes per door on a building sweep. What do you find more often — dead closers or crushed seals? — Otto Mergl, Admin
