Question: Frost forms on the metal striker plates of the doorframe when it’s extremely cold outside. Does this mean the door is leaking?
Answer: Not necessarily. Frost forming on metal striker plates in very cold conditions is often due to the metal conducting cold from the outside. When this cold surface comes into contact with the warm, moist indoor air, condensation forms and may freeze, creating frost. This is a normal occurrence and doesn’t necessarily indicate that the door is leaking. However, it’s always a good idea to check for drafts around the door to ensure it’s properly sealed.
