Removing and Replacing Thresholds

Removing and Replacing Thresholds

If your threshold is damaged, you could be wasting valuable energy.

Thresholds cover floorboard edges that end at a door, and serve as a transition element to other flooring materials such as carpet, vinyl and ceramic tile. Most thresholds are wood, although you also can buy plastic solid-surface versions, similar to solid-surface counter tops.

No matter what the material is, thresholds serve a decorative as well as a functional purpose in smoothing the way from room to room. Here's how to replace one.


  •  There are 4 steps to completing this project:
    Step 1  Remove Nails
    Step 2  Saw Threshold
    Step 3  Undercut Doorstops
    Step 4  Position the Threshold

  • Flooring nails

  • Hand Saw

Removing and Replacing Thresholds

1  Remove Nails

If the door stops (but not the jambs) are undercut, use a hammer and pry bar to remove the nails from the threshold and hammer it out from under the stops.

Saw Threshold

2  Saw Threshold

If the doorjambs were undercut to accommodate the threshold, saw it into two pieces and remove each piece separately.

Undercut Doorstops

3  Undercut Doorstops

Before installing a new wood threshold, undercut the doorstops then measure carefully and cut the threshold to length.

Position the Threshold

4  Position the Threshold

Predrill pilot holes and nail the threshold to the floor with flooring, or counterbore the threshold and fasten it with countersunk wood screws
