How to Remove an Aluminum Threshold

An aluminum threshold is the lower part of the door frame. This usually defines the transition of the different flooring types in a house. Before you consider hiring a professional to remove the threshold, it is actually a project that you can easily accomplish yourself. It can be done in an hour or so if you have the right materials.


  • Drill
  • Screw bits
  • Flat pry bar
  • Scraper
  • Putty knife
  • Filler epoxy

Step 1: Preparation

Locate the screws holding down the threshold. These are usually covered by a weather or carpet strip so remove the strip by peeling it off or removing the screws.

Step 2: Loosening the Aluminum Threshold

Remove the exposed screws using your drill fitted with the proper screw bit. Some of them may be a little more difficult to remove. You can use pliers to remove these if necessary.

Step 3: Separate the Threshold from the Floor

Now that the screws that fasten the aluminum threshold to the floor have been removed, use the putty knife to separate the edges from the floor buy cutting around them. There may be some existing caulk holding it to the floor so you have to slice through that, as well.

Step 4: Threshold Removal

Now that you have created a gap between the threshold and the floor, get the flat pry bar and slip it in the gap. Starting from a corner, pry the threshold away from the floor carefully moving along its length one inch at a time until the entire aluminum threshold is free from the existing caulk.
