How To Fix A Prehung Exterior Door’S Shattered Plastic Threshold?

To replace a damaged exterior door threshold, follow these steps:

1. Remove the damaged threshold and pry it out, being careful not to cut or pry against your finish flooring.
2. Mark and cut the replacement threshold to fit.
3. Brush or sweep the area where the threshold will go.
4. Set the new threshold into position and test it for fit.

Replace an exterior door threshold plate in most cases, such as aluminum front door threshold plates. If you want to repair a rehung door threshold, use a template to transfer the jamb’s contours to the ends of the threshold, where matching contours must be cut.

To get an exact fit on a new threshold, use a template made from 1/4-in.-thick wood glue, screws, and a new threshold. The first step is to gather the necessary tools, including a pry bar, a saw, a measuring tape, wood glue, screws, and a new threshold.

Tresholds come in wood and metal, with a rubber gasket to seal out the cold. Door threshold replacement should be done for safety and aesthetics.

Steps include knowing the parts that make up the exterior door threshold, preparing with the replacement at the ready, removing the old threshold, and prying out the old one.
