How To Trim Metal And Hardwood Exterior Inswing Thresholds?

To replace a damaged door threshold sill, measure the doorway, cut the new threshold to size using a hacksaw, and clean the area of debris or remaining caulk. Test the fit, apply flooring adhesive, place the threshold, drill pilot holes, and secure it with nails. Fill any nail holes with exterior wood putty.

There are two methods for replacing the threshold: one for metal or aluminum door sill and another for a wooden door sill. For the metal threshold replacement, measure the length and width of your current sill so you can purchase a new one at your local home improvement store. Securing the new threshold involves ensuring it is level and securely in place. Follow these steps: Place the threshold, align the threshold in the doorway, insert shims, and use wood shims to level and secure it.

To repair a damaged exterior door threshold, follow these steps: make and fine-tune the template, then measure, cut, and replace the threshold like a pro. Door threshold adjustments are usually made before the final flooring is installed, not after. To cut a metal threshold, use tin snips and a saw equipped with a metal-cutting blade. Cut the threshold flush with the wood floor, taper it slightly to be just a bit higher than the tile, and notch it so a lip covers the edge of the tile.

Best practice is to splash a bit of primer on the raw wood you’ve exposed. Depending on the configuration of your door, a new threshold may be necessary.
