Step-by-Step Guide to Common DIY Repairs

1. Repairing a Sagging or Dragging French Door

If the active or passive door is scraping against the floor, the fix is usually discovered at the hinges.

Inspect the Hinges: Open the door and check the top, middle, and bottom hinges. Search for loose screws. Often, the weight of the door pulls the top hinge screws out of the frame.
Tighten or Replace Screws: Tighten any loose screws. If the screw holes are stripped, get rid of the screws, insert wooden toothpicks covered in wood glue into the hole, cut them flush, and re-insert the screws for a tight grip.
Adjust the Hinges: Some contemporary adjustable hinges enable you to turn an Allen wrench to raise, lower, or shift the door laterally.

3. Troubleshooting Multi-Point Locks

Double French doors frequently utilize a multi-point locking system where the passive door utilizes leading and bottom flush bolts, and the active door locks into the passive door.

Lube the Mechanism: Spray a silicone-based lube into the lock holes and the locking channel. Prevent using petroleum-based lubes (like WD-40 for long-lasting lubrication), as they attract dust and grit.
Change the Strike Plates: If the deadbolt or latch misses out on the hole in the frame, loosen the screws on the strike plate a little. Tap the plate in the required instructions with a rubber mallet and retighten the screws.
