How to Keep Rain From Seeping Into the Living Room Under the Front Door

Tighten any loose hinges with a screwdriver to ensure the door is resting properly within the door frame.

Measure each side of the door frame and record the measurements. Cut the spring-metal strips to the proper sizes. Trim pieces to accommodate hinges and locks using utility scissors or metal snips.

Hold one of the spring-metal strips in the door frame so that the flared side almost touches the doorstop. Tap a nail into a prepunched hole near the top with a hammer. Use light pressure so you don't bend or dent the metal strip. Tap the next nail in toward the bottom, then fill in all the prepunched holes with nails until the metal strip is flush with the door frame.

Repeat the process with the other three sides of the door frame. When you finish, the door frame should be completely ringed with the spring-metal stripping, except where cut away for hinges and locks.

Pry open the flared end of each spring-metal strip with the screwdriver. Use light pressure to open up the metal strips to approximately a 45-degree angle from the door frame. Open and close the door a few times to test for a snug fit.
