Our weatherstripping sets come with 3 pieces - one for each side and the top or head jamb of your door. If you ordered a magnetic weatherstripping set, it includes two magnetic strips and one compression strip. The magnetic pieces are for your lock jamb and head jamb, compression piece is for your hinge jamb.
1. Remove old weatherstripping and discard
2. Wipe the area clean
3. Starting at the bottom of the door, tightly seat weatherstripping against the threshold and work your way up. Since weatherstrip shrinks a little over time, push the weatherstrip down tight against the sill, as this is the point we don’t want to ever leak. Use a wood block or other smooth hard object to seat the weatherstrip as you work your way up the jamb.  
4. Trim excess, leaving some extra for shrinkage in cold weather. We recommend using a utility knife or scissors to cut the excess at the top. You can also trim the barbed part of the weatherstripping to allow the bulb part to reach higher / seat properly, as shown in video.
5. Repeat for the other vertical jamb and then the head jamb.
6. From outside, check contact and use a putty knife to adjust weatherstripping until there is a good seal all around the door. Any spots where you can slide the putty knife in between the face of the door and the weatherstrip should be adjusted by prying the weatherstripping barb partially out of the kerf until the bulb portion of the weatherstripping tightly seals against the face of the door.

Corner Seals

1. Check for daylight in corners

2. Peel adhesive sticker and install corner seals behind weatherstripping as needed

Door Sweep

1. Open the door and remove the old sweep. If the old sweep is screwed or otherwise tightly fastened to the bottom of your door, you may need to remove the door from hinges.

2. Slide the new sweep on, using a block of wood or a hammer as needed to tap the sweep into place.

3. Trim excess with scissors, shears, or a small hand-saw.

4. Adjust the sweep up/down as needed to tightly seal (overlap about 1/8") against the top of your sill.

5. Install screws on inside of home, drilling pilot holes as needed (especially if you have a steel door). We recommend flat head 1/2" long screws. For wood or fiberglass doors, use pan head wood screws, course thread. For steel doors, use sheet metal pan head screws.

Test Operation

A well sealed door should be slightly difficult to close. It can take 1-2 weeks for your seals to slightly compress and the door to settle into smooth, tightly insulated operation.
