Threshold Installation

1. Cut or break the old threshold in half.

2. Pull out the pieces of the old threshold from the jamb (which are the wooden frames around your door). There are usually 3 to 4 screws from the other side of the jamb into both ends of the threshold that were used to hold the threshold in place for transportation. You may need to pull fairly hard on the pieces near the jamb because you most likely will be pulling 3 to 4 screw heads through the softer jamb material. Usually, you should not have any touch up to do to your jambs after pulling out the screw heads since the new threshold will cover the holes.

3. Clean out the space thoroughly.

4. Apply high quality silicone caulk liberally to the bottom of the new threshold to block water, bugs, and air.

5. Slide the new threshold into place from  the  inside  of your  house  so  the thinner(outside) front edge  of the  aluminum  goes first,  then  tuck the  rest of the threshold  into  position. lf you  have  installed  new flooring  since your original  threshold  was  installed  and  are  unable  to  slide your  threshold  into  place from the  inside of your  house,  you  will  have  to  cut  away  enough  of your jambs on  either side to  install  the  threshold.  Then you will need to patch, caulk and touch up with paint any parts of your jambs that were cut.

6. Caulk where the threshold meets the jambs on either side.

7. Adjust the sill height by turning the screws in the adjustable strip to the right height for your door sweep.  If you place a single playing card under your door between your door sweep  and  your adjustable sill, you should be able to pull the card out with a  little tension,  but  it should not fall (too big a gap between the threshold and sweep) nor be  stuck (too  small a gap  between the door sweep and the threshold ).  If you need to correct the gap, you should be able to turn the threshold screws to adjust the height of the threshold to give you the right amount of tension.

8. Stain or Sealing is optional. The adjustable oak strip is treated wood, so you do not need to stain or seal it with polyurethane, but you can if you wish. If you have one of the composite strips, you do not need to seal it.
