How to Fix a Sagging Aluminum Storm Door: Step-by-Step Guide


A sagging aluminum storm door is one that has become loose or misaligned due to wear and tear over time. This can be caused by improper installation, lack of proper maintenance, or simply age. A sagging door can be an eyesore and cause safety issues if not addressed. Fortunately, fixing a sagging aluminum storm door is relatively easy and can be done in a few simple steps.

Replace the Hinges

The first step in fixing a sagging aluminum storm door is replacing the hinges. Over time, the hinges can become worn or bent, causing the door to become misaligned. Replacing the hinges is a simple process and only requires a few tools. You will need a screwdriver, a hammer, and a drill with the correct size bit for the screws.

To begin, remove all of the screws from the hinge and then carefully remove the hinge from the door frame. Once the hinge is removed, you can use a hammer to straighten any bent areas. Then, attach the new hinge to the door frame using the same screws and drill bit. Make sure the screws are tightened properly to ensure a secure fit. Finally, reattach the door to the frame and check to make sure it is level.

Adjust the Door Closer

The next step in fixing a sagging aluminum storm door is adjusting the tension of the door closer. The door closer helps keep the door closed when it is not being used and also helps to keep the door level. To adjust the tension, you will need to find the adjustment screw on the door closer. Turn the screw clockwise to increase the tension and counterclockwise to decrease the tension. Keep adjusting until the door is level and closes properly.

Tighten the Screws

Another common cause of a sagging aluminum storm door is loose screws. Over time, the screws that hold the hinges, handle, and frame together can become loose due to vibration or weathering. It is important to regularly check these screws and tighten them if necessary. To do this, you will need a screwdriver and the correct size bit for the screws.

Start by inspecting the screws on the hinges, handle, and frame. If any of them are loose, tighten them with the screwdriver. Make sure the screws are tight enough to hold the components securely but not too tight as this can damage the frame. Once all of the screws have been tightened, check to make sure the door is still level and closes properly.

Reinforce the Frame

If the door still sags after tightening the screws, it may be necessary to reinforce the frame. This can be done by adding additional screws to the frame or by installing support brackets. To add additional screws, use a drill and the correct size bit for the screws. Drill holes into the frame and then insert the screws. Make sure the screws are secured tightly.

If the frame is still not secure enough, you can install support brackets. These brackets come in various sizes and can be attached to the top and bottom of the door frame. Make sure the brackets are installed securely and then check to make sure the door is level.

Install a New Door

In some cases, the only way to fix a sagging aluminum storm door is to install a new one. This is typically necessary when the existing door is too damaged or worn to be repaired. Installing a new door is a more involved process than repairing the existing one, but it should still be relatively straightforward. You will need a few tools, including a tape measure, a drill, and a level.

Start by measuring the door opening to determine the size of the new door you will need. Then, use a drill and the correct size bit for the screws to attach the hinges to the door frame. Make sure the hinges are secure and level. Next, attach the door closer and the handle to the door and frame. Finally, check the door to make sure it is level and opens and closes properly.


Fixing a sagging aluminum storm door does not have to be a difficult task. By following these steps, you can easily repair or replace your door and restore its functionality. Start by replacing the hinges, adjusting the door closer, tightening the screws, reinforcing the frame, adding support brackets, and then installing a new door if necessary. Taking the time to properly address any issues with your door will help ensure it operates correctly and looks great.
