Weatherstripping in St. Louis, MO: The Cheap Fix for Drafty Doors

Weatherstripping in St. Louis, MO is the cheapest fix for the most common winter complaint — the drafty door. A worn weatherstrip at the threshold, a gap at the door sweep, a cracked seal at a window — these let cold air in and heated air out, and the fix is a fraction of what the lost heat costs over a season. Here's what we seal and when.

Where drafts come from

• Door sweeps worn or missing at the threshold
• Weatherstripping at the door jamb that's flattened or torn
• Window sash weatherstrip that's cracked with age
• Gaps at the door frame where caulk has failed
• Loose thresholds that have lifted

We handle these under our doors, windows and locks and interior painting and caulking services.

The door sweep

The door sweep at the bottom of an exterior door takes the most abuse — it drags, it wears, it tears. A new sweep, sized to the door and the threshold gap, stops the draft at the source. We pair it with a check of the threshold itself, which can lift and create a gap even with a good sweep.

Weatherstrip replacement

Door jamb weatherstripping compresses over years until it doesn't seal. We replace it with the right profile for the door — foam, vinyl bulb, or magnetic for steel doors — and adjust the door so it compresses the strip evenly. A door that's slightly out of alignment can miss the weatherstrip on one side even when the strip is new.

Window weatherstrip and caulk

Windows draft at the sash weatherstrip and at the frame where the exterior caulk has cracked. We replace the sash weatherstrip and re-caulk the exterior frame — a full air-seal that pairs naturally with window repair for sash cord or balance work.
