Door Sweep Installation
Close the gap at the bottom of your door and stop cold air at the threshold.

The gap under an exterior door is one of the most common places for cold air to get in. A door sweep is the strip along the bottom of the door that closes that gap when the door is shut. Over time, sweeps wear down, tear or go missing altogether.
If there's a rolled-up towel at the bottom of your door right now, that's a sign you need a new sweep. We remove worn sweeps and install new ones that seal the bottom of your exterior doors, so you can put the towel away.

Worn, flattened or torn weatherstripping lets drafts slip around the edges of closed doors and windows. We replace it so everything closes snug and tight.
