What Causes a Door to Sag?

Before fixing a sagging door, it’s essential to understand what causes it. The most common reason is the weight of the door. Over time, the hinges may weaken, causing the door to sag.

How to Fix a Sagging Door?

There are several ways to fix a sagging door. Here are some of the most effective methods: 1. Tighten the Hinges: If the hinges are loose, it’s essential to tighten them. Use a screwdriver to tighten the screws on the hinges. This will help lift the door and fix the sagging. 2. Replace the Hinges: If the hinges are severely damaged, it’s best to replace them. Purchase new hinges from a hardware store and install them on the door. This will help distribute the weight of the door evenly and fix the sagging. 3. Add a Support Strut: Installing a support strut to the door frame can also help fix the sagging. This will provide additional support to the door and prevent it from sagging. 4. Adjust the Strike Plate: The strike plate is the metal plate on the door jamb where the latch engages. If it’s not aligned correctly, it can cause the door to sag.
