An entry door threshold can become damaged or worn over time. If the only problem is that the rubber seal no longer provides a tight seal on the door, you may be able to replace the rubber seal, rather than replacing the entire threshold.
Replacing an Entry Door Threshold
Remove Old Threshold: Remove the rubber strip on the existing entry door threshold, unscrew the screws holding the threshold in place, and remove the old threshold.
Cut New Threshold to Size: Remove the rubber seal from the top of the new threshold, and cut the threshold to fit with a hacksaw using the old threshold as a pattern.
Fit Threshold to Door: Trial fit the threshold to make sure it provides a snug fit against the bottom of the door. If it doesn’t, you may need to adjust the door or slightly shim the threshold.
Attach New Threshold to Floor: Screw the new threshold to the floor. If the floor is concrete, use a carbide tipped masonry bit to drill holes for either masonry screws or plastic anchors.
Install Rubber Seal: Cut the rubber seal to length with a utility knife, and insert it into the grooves in the threshold.
Check Threshold Fit: Close the door and check to make sure the threshold fits snugly against the bottom of the door.
