How to Fix Sagging Doors: A Comprehensive Guide

Tips and Tricks – Doors that sag are not only frustrating, but they can also be a safety hazard. A sagging door can lead to misalignment, causing the door to not close properly and even create gaps that can compromise your home’s security. Fortunately, fixing a sagging door is a relatively simple task that you can accomplish yourself. 

In this article, we will discuss how to fix sagging doors and restore them to their proper function.

What Causes Doors to Sag?

Before we dive into the steps to fix a sagging door, it is essential to understand what causes doors to sag. Here are some common reasons why your door may be sagging:

Loose Hinges

Hinges that are not securely fastened to the door or frame can cause the door to sag. Over time, screws that hold the hinges in place can become loose, causing the hinge to pull away from the frame or door. This will make the door misaligned and sag.

Worn Hinges

Hinges can wear out over time, especially if they are used frequently. The hinge’s pin can become worn, causing the door to sag or even fall off the hinges entirely.

Settling of the House

As your home settles, the door frame can shift, causing the door to become misaligned and sag.

Steps to Fix Sagging Doors

Now that we have covered the common causes of a sagging door let’s look at the steps you can take to fix it.

Step 1: Inspect the Hinges

The first step in fixing a sagging door is to inspect the hinges. Check to see if the screws are loose or if the hinges are worn. If the screws are loose, tighten them. If the hinge is worn, replace it with a new one.

Step 2: Check the Strike Plate

Make sure that the strike plate is not loose or out of alignment. The strike plate is the metal plate attached to the door frame where the latch engages. 

If the strike plate is loose or misaligned, it can cause the door latch to not engage correctly, resulting in the door sagging.

Step 3: Check the Door Jamb

Check the door jamb, the part of the door frame that the door latches into. The jamb can become damaged over time, causing the door to become misaligned. 

If you notice any damage to the jamb, repair it before moving on to the next step.

Step 4: Shim the Hinges

If the hinges are still causing the door to sag, you can try shimming them. Shimming involves placing a small piece of material, such as cardboard or a wooden shim, between the hinge and the door frame. This will help to realign the door and prevent it from sagging.

Step 5: Replace the Door

If all else fails, you may need to replace the door entirely. A door that is severely damaged or warped may not be fixable, and it is more cost-effective to replace it.


Fixing a sagging door is a simple task that you can accomplish yourself. By following the steps outlined above, you can fix a sagging door and restore it to its proper function. 

It is important to address the issue of a sagging door promptly, as it can compromise your home’s security and safety. 

By inspecting the hinges, strike plate, and door jamb, and shimming the hinges if necessary, you can fix a sagging door and prevent future issues. 

If all else fails, replacing the door may be the best option.
