A client recently asked me if I had any ideas why his house was so dusty. I stopped by to take a look and figured out the problem right away. The air vent boots in the ceiling weren’t sealed at the drywall, so when the heat or air conditioning turned on, air was being pulled in from the attic along with dust. The dust around the vent cover was a clue this was the case. When I pulled the cover off, sure enough, I could see right into the attic.
This is an easy do-it-yourself project. Here’s what you need to do to caulk your vent boots:
- Run a razor knife between the vent cover and the drywall to make sure they aren’t stuck together
- Remove the vent cover
- Apply caulk to fill the gap between the drywall and the vent
- If the gap is too big for caulk, use spray foam insulation
- Wash the vent cover
- Install the vent cover
