Are your house doors solid and secure enough? Beefing up exterior doors is a good and inexpensive way to improve home security. Start by removing the inside trim around the door. Doorframes are hung between rough framing and are rarely a snug fit. You'll find some filler or shims were initially used to secure the frame but adding more will only make it stronger. Add blocks or shims behind all hinges and around the latch and deadbolt strike plates. Make things snug, but don't move the doorframe. While in there, fill any open spaces with expanding foam to stop drafts. Reattach the casing using finish nails, and replace hinge- and strike-plate screws with new ones that are at least 1 inch longer. This will hold deeper into framing and strengthen the overall installation. When you're through, it might not look any different, but you'll have peace of mind. And that's the On The House tip for today.
