Why do my French doors keep sagging?

French doors are heavy due to the big glass panes. Requirement ¾-inch hinge screws frequently take out of the framing over time because they only anchor into the door jamb, not the structural framing stud behind it.

Examine your door sweep first; if it is used, change it. Additionally, ensure a bead of exterior-grade silicone sealant is applied underneath the threshold.
