1. Determine Lead Safe Work

• Review work orders to determine if Lead Safe RRP is required. When required, follow RRP guidance in section Lead Safe Work section.

2. Determine correct door for location

• Exterior doors shall be exterior-grade and insulated.

• 20 minute fire rated doors shall be installed if between dwelling and garage (IRC R302.5.1)

3. Check fitment

• Before removing the old door check that the new door is the proper size.

4. Remove old door

• Remove existing door and frame to expose the rough framing in a way that doesn't damage finished surfaces or doorbell wiring.

5. Level sill

• If Sill is 1/4" or more out of level, secure a tapered pressure treated board to span the width of the threshold to make it level and add stability.

6. Protect sill

• Install some sill plate gasket or flashing tape and caulk under the threshold before inserting the pre-hung door.

7. Insert new door

• Insert pre-hung door with the brick mold still attached if possible, plumb the hinge side, and fasten with 3 or more 3" grabber screws either behind the kerf or in screw hole in the hinge.

8. Shim, adjust, and fasten new door in place

• Shim the adjacent side up (won't need if step 2 was performed) until the reveal at the top of the frame is even with the top of the slab and fasten with 3" grabber screws at the top 3 inches, middle, and bottom 3 inches.

• May need to install shims under the threshold in multiple areas for rigidness.

• Make sure shims are installed between the frame and jack stud so the frame will not bow away from the slab creating a poor seal.

• You may need to move the upper or lower corners in or out, so there is even contact with the kerf.

9. Air seal new door

• Once the frame is hung, insulate with either backer rod or foam.

• Foam is preferred due to its continuous seal, adhesion to the materials, and it's ability to expand to the width of the door jam.

• Be sure to use a low-expanding foam, so it does not bow the door frame making it difficult to close.

10. Install door hardware

• Install the door hardware and make sure it all aligns and closes in a way that it creates a full seal.

• Adjust the threshold so there is no daylight seen through the bottom of the door, and door opens and closes smoothly.

11. Install interior trim & caulk

• Install the interior trim and caulk the edges.

• Caulk the brick mold and threshold with an exterior grade caulking.

12. Worst Case Draft Test

• Conduct a Worst Case draft test to verify any Category I, II, or III appliances are venting safely before leaving home for the day.

• Testing shall recorded using the Utah WAP Worst Case Draft form.
