10 Easy Ways How to Fix a Sagging Door: Make Your Door Aesthetic and Functional

One of the problems with doors is that they sag. When your door is sagging, you should expect it to become more than inconvenient. This is because sagging can prevent the door from closing properly or cause it to drag the floor. So, when the door is sagging, it leads to aesthetic and functionality problems.

The good news is that a sagging door can be fixed! Fixing a sagging door is often simple, using a few steps and basic tools. Whether you’re fixing various doors from different manufacturers, the ways on how to fix a sagging door are the same. To know more about these ways, we have listed the steps below.

Causes of a Sagging Door

There are various reasons why a sagging door will occur. Here are the most common causes you should know:

Old or New Door

One of the reasons is due to these doors being old or new. When the door is old or new, the screw on the top hinge can lose, deteriorate, or start to pull out completely. For instance, an old door follows a 2-hinge rule, one at the bottom and one at the top. However, the top hinge might carry a heavier weight, making the distribution not balanced.

Overloaded or Heavy Door

If the doors are too heavy—like those made of metal, aluminum, or wood—the weight can cause the hinge to bend or lose, this is why doors that do not have enough of a hinge can cause the door to sag because the weight is not evenly distributed.

Paint or Stain Under Hinges

A sagging door is probably caused by the paint or stain under the hinges. Paints or stains are common for old homes as they are in constant need of remodeling and renovation. So, those paints and stains can cause the hinge to be pushed upward, causing the door’s misalignment.

Improper Installation

You can also trace the cause of the sagging door to improper installation. The door might start to sag sooner if the door is not aligned or has the wrong number/type of hinge.

Environmental Factors

There are also other external factors that cause doors to sag. One of these factors is the weather, particularly, humidity, temperature fluctuations, or the house’s natural settling. These factors can lead to doors contracting or expanding, causing a change in their alignment.

10 Ways You Can Do To Fix a Sagging Door

Sagging is a problem in the aesthetic and functionality of the door. However, they can be easy to fix. The following ways can be used to fix a sagging door.

1. Tighten the Hinge Screws

A sagging door can happen if there are loose screws. The doors can have loose screws when it is used all the time. This means that the door is exposed to wear and tear. One of the ways to fix this issue is tightening the screw hinge. When you tighten the screw hinge, the door will not cause any friction. So, what you can do is to tighten the screws, even those that are attached to the frame.

2. Change the Hinge Screws

If you tighten the hinge screws yet sagging still occurs, maybe it’s time to change it. There are times when the screws are too small to fit the hinge. When the hinge screws are small, it does not dig deep into the frame and stub. Since it’s not attached to the door, it doesn’t properly hold and support its weight. This is why you need to change the hinge screws to something larger and add more screws if needed.

3. Fill the Hinge Holes That Were Removed

There are times when too much weight on the door can cause pressure on the hinge. This pressure may lead the screws on the hinge to loosen and get damaged. When this happens, you must fill them in using a wood filler. The first thing to do in this way is to check the screws. If the screws are not attached to the jamb or door, you must remove the screws. You must also clean any debris or dirt from the screw holes.

If the holes are not too damaged, you must fill the hole using a wood filler. Smoothen the hole after using sandpaper so that it’s flush with the surrounding wood. If the holes are too big, you can use wood dowels. Cut this dowel into an appropriate length, add the glue, and slide it into the hole. After the glue dries, trim off any extra dowels and sand the surface. Once the filler is dried and smooth, you should drill new pilot holes for the screws to fit.

4. Insert Shims Behind Hinges

Another way to employ when fixing a sagging door is to adjust the door. Shims is a small, wedge-shaped material that can be used to move the door to its proper alignment. What you need to do is to first examine which hinge is causing the door to drop. If the top door is sagging, you need to add the shims to the top hinge. You need to do the same thing if the bottom door is sagging by adding shims at the bottom hinge.

When the hinge is damaged, the best thing to do is remove it. When doing this, remove the hinge pins and then remove the door. When it’s done, cut the right size and place them into the hinge gap. This step will raise the door to its proper level. Place the shims one layer at a time until the door is in the correct position. Once done, re-hang the door by aligning the hinge with the frame and reinserting the hinge pins.

5. Remove Shims Behind Hinges

Sometimes, shims are added to fix a sagging door. However, when the door is still sagging despite adding shims, maybe it’s time to remove the shims and replace them with a new hinge. So, take off the hinge to reveal the shims, remove it, and add a new hinge.

6. Remove Paint from Hinges

The paint on your door can build up on hinges, which causes it to sag. This is why you need to remove the paint from the door by removing both the door and the frame. Then use a drill or screws to remove the hinge that secures the door and frame. When the hinge is removed, scrape away accumulated paint from the jamb or mortises using a chisel or sharp blade.

If the paint is hard to remove, apply a paint remover or thinner. Ensure that once the remover works, use the scraper or putty knife to remove the loose paint. Also, ensure that you remove the paint to reveal its bare surface.

7. Replace Hinges

When your hinges are old or worn out, you must replace them. Replacing hinges can help the weight of the door to be balanced on the surface. If all the ways are not working, you need to remove the old hinges. When doing this process, you must remove screws from the door and frame.

In addition, take your new hinge and compare the size and style to your old hinge.  After doing so, measure and mark the location of the new hinge on the door and frame. Using your tape measure, ensure that you place your new hinge in the same location as your old hinge. Position the new hinge to the mark location and carefully replace it using a screwdriver or drills.

8. Sand the Door Jamb

One of the ways to fix a sagging door is through sanding. The process of sanding the door jamb will enhance the fit of the door. When the door is fitted, it can prevent friction and misalignment. Sanding the door can also help smoothen out the rough edges, preventing the door’s smooth movement.

When sading the door jamb, use medium-grit sandpaper. This sandpaper is around 120 to 150 grit. You must also sand the door in a gentle manner and frequently check if the door can now properly fit the jamb. You can also paint or stain the door to ensure a uniform appearance.

9. Tighten the Jamb

When you replace the hinge, but it does not work, maybe the problem is on the jamb. So, another option is to pull the jamb on the latch side to the framing. In doing this step, you must drill a pilot hole where the door is sagging. After drilling the screw holes, you need to apply a wood filler.

10. Inspect the Strike Plate

What you need to do first is check the strike plate. When the strike plate does not fit the door latch, you can expect that the door will sag. If you want to prevent that, you must adjust the plate by loosening the screws. And when the door latch and strike plates align, you need to tighten the screws.

The Tips That Keeps The Door From Sagging

A sagging door is a problem both for you and your space. To prevent this, some of the tips and solutions you can find are the following:

Avoid Overloading the Door

Excess weight caused by many factors like hinges, door handles, or locks can put pressure on the door. This pressure can lead to the door’s sagging over time. To prevent such an issue, you should be mindful of what you’re putting in the door. You should limit the amount of attachments or use lighter materials. This is also a must if you have older doors because they are more vulnerable and susceptible to sagging.

Use Quality Hinges

Another tip you can follow is to use high-quality hinges. Hinges can sustain the door’s weight and keep its correct alignment. This is why you must choose a high-quality hinge made of sturdy material and ensure the right size for your door.

Maintain the Door Frame Condition

Uneven or misaligned door frames can also cause your door to sag. This is why you must frequently check and maintain your door frame, as any signs of damage or shifting can cause sagging. When this happens, you can repair or re-shim the door frame to adjust the alignment. Over time, a properly aligned frame can support and stop doors from sagging.

You must also ensure that the doors are high-quality because when the door is not high quality, it can create friction with the door. There are many high-quality door options in the market; some even include affordable doors.

Regularly Lubricate Hinges

The door’s movement can cause friction that leads to them changing. To prevent this from happening, you must lubricate the hinges using oil products. Apply these directly to the hinge pins and other moving components. This lessens tension and keeps the hinges operating smoothly.
