How to Find Door Drafts and What Causes Them?

It’s pretty easy to identify your exterior entries needing solutions for drafty doors and fixing drafty doors, as you just feel the cold air.

There are two tests to perform in finding door drafts:

  1. Flame test. A match or lighter is all that is required. Create a flame first, then advance it down the door frame's crease. Additionally, look at the spot where the door slab and frame connect. A draught and the exact location of the vulnerable position are both directly indicated when the flame starts to flicker.
  2. Paper test. Works similarly to the flame test by using a piece of paper instead. By moving it, the paper starts waving, indicating that air is entering from the particular spot.

Main Causes of drafty doors:

  • Old or worn weatherstripping is the most frequent cause of drafty doors.
  • Door hinges and screws are loosened or not installed properly.
  • The door sweep is missing or is not aligned properly.
  • Sill is set too tight, being too low.
  • An old worn door that needs to be replaced. Wood doors are significantly more likely to be drafty because they are not foam insulated. Steel and fiberglass doors from Vinyl Light are insulated and significantly better at blocking draughts.
  • Rotten door frame. It happens with older homes and wooden doors in most the cases. Door replacement is strongly recommended. Otherwise, to keep outside air out, you must devise strategies by sealing drafty doors to close gaps between the slab and the frame.

The negative effect of drafty doors:

  • Increase costs on energy bills.
  • Uncomfortable living.
  • Risk of moisture leading to mold.
  • Bigger gaps allow insects and parasites into your home.
