Homeowners, especially those living in climates with more extreme temperatures, often fail to realize how much they spend for heating and cooling because of a single door threshold that is worn, broken, or improperly installed. To save yourself the unnecessary cost of warm or cool air escaping from your home, check and replace all door thresholds through which this air can leak. Here are 4 simple steps that will help you quickly and easily manage these replacements.
Step 1 – Prepare before Buying Your New Threshold Strip
In purchasing new door threshold strips you'll need to know which sizes will best fit the doors where you plan to install new strips. Measure each door separately. All doors do not necessarily have the same dimensions. You'll need two measurements for each door: the width of the doorway—not the door, itself, and the gap between the floor and the bottom edge of the door. Take these measurements with you when you buy your new threshold strips. Examine the space between your door and the floor below it to determine what has created this space. Is the strip was not high enough? Is the strip the right size, but is now worn down or broken off?
Step 2 – Choose from Available Strip Types
You'll find a larger variety of weather strip types if you buy them at a store with a wider selection. Be prepared to chose from one of the following strip types:
Wood strip that will entirely replace your existing strip
Wood that will be attached to an existing strip
Metal strip that will be attached to an existing strip
Aluminum strip with a plastic or rubberized weather strip in the middle.
Be sure to check the measurement of the strips you purchase, to ensure that they match the strips you measured at home, and that they match the type you'll need to fill the gap between door bottom edge and the floor beneath it. If you are unable to find a strip long enough to match your old strip, buy one that is longer, one you will be able to cut and fit to your threshold.
Step 3 – Remove the Old Strip
Locate the screws that attach the strip to the floor. If no screws are visible, and if you see a rubber or plastic strip in the center of the old strip, use a flathead screwdriver to remove this strip. It's very likely that you'll find your screws in the channel the rubber strip occupied. Use your screwdriver to remove the screws that hold the old strip to the floor.
Step 4 – Attach Your New Threshold Strip
If you need to shorten your new strip, carefully measure and mark it. Then, cut it to length with a handsaw for a wood strip, or a hacksaw for a metal strip. Check to see if holes in the new strip are aligned with screw holes in the floor. If they're not, use your drill and bit to drill new holes that will line up with the new strip holes. Then, attach the strip with new screws. Use this same procedure for other strips you need to replace.
