How do I install a new threshold?

  • Remove your old threshold. You may need to use a chisel or a pry bar. Be careful to avoid damaging your floor or trim.
  • Vacuum or sweep the floor to remove any dust and debris.
  • Measure the width of your door opening, as well as the distance between the bottom of your door and the floor.
  • Cut your new threshold to fit the width of your door opening.
  • If necessary, notch your threshold so that it fits around any stops on the doorframe.
  • Caulk the doorway between the door frame. This will ensure that your threshold has an airtight seal.
  • Tap the new threshold into place with the sloped edge facing away from the house.
  • Drill holes in the threshold that are slightly narrower than the nails you plan on using to secure the threshold to the floor.
  • Nail the threshold into place.
  • Fill the holes with wood filler and sand when dry.
  • Apply stain and/or a varnish to seal the threshold against moisture.
