TL;DR
A threshold adjustment is the raising or lowering of the adjustable cap on an exterior door sill, via the row of screws along its top, so the door bottom compresses the sweep just enough to seal without dragging. Done seasonally or after sweep replacement, it cures daylight visible under the door and water blowing in at the corners.
What it means
A threshold adjustment is the raising or lowering of the adjustable cap on an exterior door sill, via the row of screws along its top, so the door bottom compresses the sweep just enough to seal without dragging. Done seasonally or after sweep replacement, it cures daylight visible under the door and water blowing in at the corners. Turning the screws a quarter turn at a time and testing with a dollar bill drag is the standard field method.
