Issue 1: Sagging or Misaligned Doors

The most common grievance concerning French doors is that they begin to drag on the floor or stop working to latch effectively. This generally occurs since the weight of the glass triggers the hinges to slip or the frame to shift.

How to Fix a Sagging French Door:

  1. Check the Hinges: Open the door and check the hinge screws. Often, the screws protecting the leading hinge to the door frame have loosened under the weight of the door.
  2. Tighten Up or Replace Screws: Tighten any loose screws. If the screw holes are stripped, eliminate the screws, insert wooden toothwood dipped in wood glue into the holes, let it dry, and reinsert the screws for a tight grip. Additionally, change the short screws with longer 3-inch screws that anchor straight into the framing stud behind the door jamb.
  3. Change the Hinges: Many modern-day French doors feature adjustable hinges. Utilizing a hex wrench, turn the adjustment screws clockwise or counterclockwise to raise, lower, or move the door laterally until it aligns equally with its equivalent.

  3. Install New Weatherstripping: Cut the brand-new material to length and press it securely into the channel. Ensure there are no spaces at the corners.
  4. Inspect the Sweep: Inspect the bottom door sweep. If light shines underneath the door, adjust or change the sweep to block out air and moisture.

Concern 3: Sticking or Binding

If the doors bind against the frame midway through opening or closing, the concern may be seasonal humidity modifications causing the wood to broaden, or a distorted frame.

Quick Fixes for Binding Doors:

  • Sand the Edges: If minor swelling is the offender, remove the door, gently sand the binding edge with a belt sander, and use a fresh coat of paint or sealant to prevent future wetness absorption.
  • Re-shim the Jamb: If the frame itself runs out square, the housing may need to be popped off, and the shims behind the jamb changed utilizing a pry bar and wood shims.
