TL;DR
A door sweep is the flexible seal, vinyl fin, rubber blade, or brush strip in an aluminum carrier, fastened along the bottom of a door to close the gap above the threshold. That half-inch slot is the largest single air leak on many entries, and the same gap admits drafts, dust, light, water, and, at a quarter inch, mice.
What it means
A door sweep is the flexible seal, vinyl fin, rubber blade, or brush strip in an aluminum carrier, fastened along the bottom of a door to close the gap above the threshold. That half-inch slot is the largest single air leak on many entries, and the same gap admits drafts, dust, light, water, and, at a quarter inch, mice. Screw-on carriers allow height adjustment as the threshold wears, and replacement is a ten-minute job; pest-control inspectors flag daylight under exterior doors as routinely as energy auditors do.
