How to fix broken door threshold
Install door threshold with construction glue
Simple and Easy Replacement of Entry Door Threshold
HOW TO INSTALL FRONT DOOR THRESHOLD WITHOUT USING SCREWS
1. The most common size of threshold is 5-5/8 inches, but that was not wide enough for my door. I needed one that was at least 7 inches wide or 7 - 9/16 inches.
2. Door jambs normally come in 2 standard sizes: about 4.5 inches (4 - 9/16 inches) and about 6.5 inches (6 - 9/16 inches).
3. If using Endura Adaptive Inswing Sill System from BetterDoor, you will need to install ½ inch or thicker plywood underneath the threshold.
4. To nail in the plywood board, I used 2 ½ inch 16-gauge finish nails.
5. I used construction glue to attach the threshold to the plywood, and that worked beautifully! Best value glue is Loctite PL 3x Premium.
6. How I repaired the door jam and replaced the brick molding are shown in separate videos.
