sagging doors are common In older homes. It’s practically a certainty that the doors, like the foundation and other structural features, will ultimately sag. Sagging doors can occur in newer homes as well if the door was not properly built or if too much weight was placed on it. The good news is that it’s simple, quick, and affordable to fix sagging doors. You can quickly realign the door so that it swings freely with the help of a few simple tools. Hence, in the next section, we’ll look at how to fix a sagging door that won’t latch.

What Causes a Sagging Door?

Over time, simple wear and tear can cause a sagging door, but other factors might also contribute. The door hinges may wear if your kids have been yanking or hanging on the doorknob. A previous resident might have placed a spacer into one of the hinges to make the door close tightly in the past. 

The door may sag more quickly as a result of this. If you’ve given the door multiple coats of paint over the years, this may have exacerbated the problem because painting it can also cause it to fit differently in the frame. A new doorknob installation, for example, can occasionally cause your door to become out of alignment.

How to Fix a Sagging Door That Won’t Latch

You’ve come to the right place if you need to know how to fix an uneven door, how to fix a door that is sticking, or how to fix a door in general. We’ll start with the simplest solution because there are other methods to fix a sagging door that won’t latch.

#1. Tighten Existing Hinge Screws

Tighten all of the screws in the top hinge with the cordless drill or manual screwdriver by twisting clockwise. Also, tighten the screws on the door and jamb sides. Often, this repair alone is enough to fix a sagging door that won’t latch.

#2. Remove Hinge Spacers

A prior owner may have installed a spacer on the top hinge. The spacer could be a thin strip of cardboard fitted under either hinge leaf and was most likely designed to make the door fit more firmly into the frame.
If a hinged spacer is visible, remove it by unscrewing the screws. Remove the spacer, toss it, and replace the hinge. Once more, try the door.

#3. Install New Hinge Screws

Classic hinge screws measure 1 inch in length. If you tighten the current screws and they keep turning, you will need to make the screws longer. Make use of a 1 1/2-inch screw. You might also try replacing the old screws with ones with a coarser thread.

#4. Use a 3-inch screw to replace the hinge screw.

Replacing one of the top-hinge screws with a 3-inch-long screw is a very effective approach to fix a sagging door that won’t latch. This brings the hinge closer to the door jamb, as well as the entire door frame closer to the stud.

  • Remove all three screws from the hinge on the side of the door jamb.
  • Insert a 3-inch screw into the hinge’s middle hole using the cordless drill.
  • Replace the other two screws in the top and bottom positions.

#5. Remove the Paint From From under the Hinge

Remove the hinge as you would spacers from under it, then use a wood chisel or the sharp blade of a five-in-one tool to scrape away accumulated paint in the mortises or from the door jamb.

The goal is to remove all paint and restore the door’s edge to bare wood while avoiding the removal of too much wood. Avoid using a utility knife or razor blade.

#6. Tighten the door jamb’s top.

Drive a 3-inch screw into the top of the door jamb on the latch side if you have tightened the door to the jamb and it is still sticking.

#7. Bend Back Top Hinge

Lift the door off its hinges by unscrewing the pins and sliding the door off the hinges. Using a hammer, gently tap the three knuckles (the barrel-shaped section that holds the pin). Place a scrap piece of wood between the hammer and the knuckles to cushion it.

#8. Sand Top Edge of Door

By hand or with an orbital sander, sand the top edge of the door. The sticking region is frequently identified by large scuff marks. Sand carefully. After lightly sanding the door, try closing it. Repetition is necessary until the door can open and close without touching the jamb.

#9. Sand Top Section of Door Jamb

The top of the door jamb, where the door sticks, should be sanded similarly to the top edge of the door. The door jamb adapts to the door’s tilt, which essentially remains unchanged.

#10. Replace the Hinge

As metal scrapes against metal and wears away, some very old hinges will naturally loosen over time. If a pin rattles or slides while in position, the hinge is probably not as tight as it may be.

You might be able to replace the pin with a new one. If you can’t find a single hinge that matches the door’s other hinges, replace the hinge fully. Perhaps you can replace all three hinges at once.

How to Fix a Sagging Door by Tightening Hinges

Loose hinges are a typical issue that can cause sagging doors. If this is the case, you must level the sagging door. We’ll also show you how to fix a stripped screw hole if you come across one.

Tool and Materials Needed:

  1. Screwdriver
  2. 3-inch screws
  3. Electric drill
  4. Toothpicks
  5. Wood glue
  6. Scissors

Step 1: Tighten the Screws

Look for any loose or missing screws when inspecting all door hinges. Tighten any loose screws and replace any that are missing. When tightening the screws, be sure to lift or raise the sagging door and support some of its weight while doing so. If the screws tighten and your hinges appear to be back on course, you can end here. The holes may be stripped if the screws are not tightened. In that case, proceed to Step 2.

Step 2: Replace with Longer Screw

If the screws spin and the hinge shows no indications of tightening, the screw holes may be stripped. To tighten the hinge, try replacing the original screw with a longer one (three inches would be fine). To get a greater bite, a longer screw simply penetrates the door jamb deeper.

Step 3: Fill in the Hole

Alternatively, you can tighten the screw hole. Remove the screw first. Insert a few wooden toothpicks into the screw hole after coating them with wood glue. Then, snap or cut off the toothpicks that protrude from the screw hole. Make sure your cut is flush with the door or jamb. Reinstall the hinge and screw it back into the hole.

How to Fix a Sagging Door with Shims

If tightening the hinge and addressing the stripped screw doesn’t work, you may need to proceed to the next step, which is shimming the door. By shimming the door, you essentially put something behind the hinge (in this example, thick paper rather than traditional wooden shims) to tighten the space and improve the hinge’s grip.

Tools and materials required:

  1. A screwdriver
  2. A thick sheet of paper (cardboard from a cereal box is great for this)
  • Examine Door: Inspect the door to discover which hinges require shimming. It’s most likely the top hinge if the door is sagging.
  • Remove the Hinge: Remove the hinge with a screwdriver.
  • Replace Hinge: Place a thick piece of paper between the hinge and the jamb.

How to Fix a Sagging Door by Drawing the Jamb In

If your door is sagging due to swelling or settling and neither of the previous two procedures works, try drawing the jamb in.

This has the same effect as tightening the hinges, but you’ll be working on the latch side of the door rather than the hinge side. While it may appear complex, this approach simply just pushing a long screw into the jamb to compress it into the door frame, resulting in more space between the jamb and the door.

Tools and materials required:

  1. Electric drill
  2. a three-inch screw
  • Inspect the Door: Determine where the door appears to be pressed against the jamb. The screw will go in there.
  • Drive Screw: Draw the jamb into the door frame by driving a three-inch screw into the jamb.

How to Fix a Sagging Door by Sanding

Your door may have expanded if loose hinges and crooked door jambs aren’t the problems. High humidity causes doors to do this. In that case, you can move on to the next possible fix—sanding or planing the door. Simply put, this means you are removing wood from the door’s edge. To do this correctly, scribe the door so you know how much to sand or plane off.

This method is more difficult and needs a little more know-how, but it’s the last thing homeowners should do before sounding the alarm and calling for expert assistance.

Tools and materials required:

  1. Carpenter’s compass
  2. Pencil or masking tape 
  3. Standard screwdriver
  4. Slotted screwdriver
  5. Hammer
  6. Coarse sandpaper
  7. Hand planer or belt sander
  8. 120-grit sandpaper
  9. Paint and painting tools
  • Mark the Door: With a carpenter’s compass, mark the door 18 inches from the door’s edge facing the jamb.
  • Remove Pins: Once you’ve determined where you’ll be sanding, remove the hook pins on the door and transfer them to an open location where you can work on a level surface.
  • Sand or Plane Edge: Sand or plane the edge you marked. You can use a hand planer for this step.  While sanding your door, go slowly; you don’t want to be too hasty and wind up with a whole new problem since you sanded off too much.
  • Smooth Wood: After sanding off the area of the door you indicated for removal, use 120-grit sandpaper to smooth off the wood.
  • Repaint: Once the edges have been smoothed, you can repaint them and replace the door.

When to Hire a Professional

All of the repairs suggested above are doable by homeowners and experienced DIYers. If none of these methods work, it could be a sign of a larger problem, such as settling or a problem with your foundation.

In some cases, the next step would be to repair the door frame itself.  Fixing a door frame frequently includes working with drywall, and if you’re not familiar with it, you run the risk of exacerbating the issue.
