Are Mail Slots Drafty?

Yes, mail slots are drafty. The reason for this is that the slot is designed to allow air to pass through it in order to prevent the door from slamming shut. This air flow can cause a draft in the home, especially if the slot is located near an exterior door. There are a few things you can do to help reduce the drafts coming through your mail slot. First, make sure the slot is properly sealed around the edges.

You can use weatherstripping or caulking to help seal any gaps. Second, you can install a cover over the mail slot to help keep out drafts. These covers are available at most hardware stores. Finally, you can keep your interior doors closed as much as possible to help limit the amount of drafts coming into your home.
