5 Steps to Fix a Sagging Exterior Door (The Ultimate Guide)

Sagging exterior doors can be a common problem in many homes. This issue not only affects the overall appearance of your home but can also lead to energy efficiency and security concerns. If you have noticed that your exterior door is sagging, there are several steps you can take to fix the problem.

In this guide, we will discuss how to fix a sagging exterior door with simple and easy-to-follow steps.

Causes of sagging exterior door

Before we go to the solutions, let’s first understand what causes an exterior door to sag. Here are some common reasons:

  • Age: Over time, the weight of the door and constant use can cause it to sag.
  • Loose hinges: Hinges that are not properly tightened or have become loose over time can cause a door to sag.
  • Foundation issues: If your home’s foundation is not stable, it can cause the door frame to shift and lead to sagging.
  • Extreme weather conditions: Exposure to extreme temperatures, moisture, and humidity can cause the door frame to expand or contract, leading to sagging.

Tools and Materials Needed:

Steps to fix a sagging exterior door

Step 1: Identify the problem area

The first step is to identify where exactly the door is sagging. This will help you determine the cause of the issue and the essential steps to fix it.

Step 2: Tighten the hinges

In most cases, sagging exterior doors are caused by loose hinges. Use a screwdriver to tighten all the screws on the door’s hinges. If you notice any stripped screws, replace them with longer ones for a more secure fit.

Step 3: Check the frame and foundation

If tightening the hinges doesn’t solve the problem, check the door frame and make sure it is properly aligned. Also, inspect your home’s foundation for any signs of shifting or settling that could be causing the door to sag.

Step 4: Use wooden shims

If your door is still sagging, you can use wooden shims to adjust its position. Place a shim between the door frame and the hinge that is closest to the sagging area. Use a carpenter’s level to ensure that the door is straight and adjust the shims as needed.

Step 5: Reinforce with wood glue

To further secure the shims, apply some wood glue before tightening the screws. This will provide extra support and help prevent future sagging.

Step 6: Replace the hinges

If your hinges are damaged or worn out, they may need to be replaced. Make sure to choose high-quality hinges that can support the weight of your door.

Step 7: Adjust the strike plate

In some cases, sagging exterior doors may be caused by a misaligned strike plate. Use a hammer and chisel to regulate the strike plate and make sure that it aligns properly with the door latch.

Step 8: Add additional support

For heavier doors, or if the sagging is severe, you may want to add additional support. This can be done by installing a metal door bracket or reinforcing the frame with wooden blocks.

Common problems and solutions 

  • Problem: The door still sags after following all the steps.

Solution: If the door is still sagging, it may be necessary to replace the entire frame or get professional help in realigning it.

  • Problem: The door doesn’t close properly after fixing the sagging issue.

Solution: Check if the strike plate is aligned correctly and adjust it as needed. If the strike plate is damaged, replace it with a new one.

  • Problem: The door becomes stuck or difficult to open and close after fixing the sagging issue.

Solution: This could be caused by excess friction between the door and the frame. Apply some lubricant or wax on the edges of the door to reduce friction and make it easier to open and close.
