How to Fix a Door That Won't Close

A door that will not close properly is one of the most common household annoyances, and in Los Angeles it is especially prevalent. Between the seasonal humidity swings, the hot Santa Ana winds that dry out wood, and the gradual settling of older homes built on clay-rich soil, doors in LA homes take a beating. The good news is that most door problems are straightforward to fix yourself with basic tools and less than an hour of your time. If your door also squeaks when you move it, check out our guide on how to fix a squeaky door while you are at it.

In this guide, we will cover the most common reasons a door won't close and walk you through each fix step by step. Whether your door is sticking, won't latch, or swings open on its own, you will find the solution here.

Why Your Door Won't Close: Common Causes

Before you grab any tools, take a close look at how the door is failing. The way it misbehaves tells you exactly what is wrong:

• The door sticks or rubs against the frame — This usually means the door or frame has shifted. In older LA homes, foundation settling is a frequent cause. Humidity changes can also swell wood doors, especially in neighborhoods closer to the coast like Santa Monica, Venice, or Marina del Rey.
• The door closes but the latch does not catch — The strike plate and latch bolt are misaligned. The door has likely sagged due to worn hinges or the frame has shifted slightly.
• The door swings open on its own — The hinges are not plumb, meaning the door is not hanging straight. This is common in homes where the foundation has settled unevenly.
• The door won't shut at all and the gap is uneven — The door may be warped, or the hinge screws have pulled out of the wood, causing the door to sag dramatically.

Fix 1: Tighten or Replace Loose Hinge Screws

This is the single most common reason a door won't close, and it is the easiest to fix. Over time, the screws holding the top hinge work loose from the repeated stress of opening and closing. When the top hinge loosens, the door sags and the opposite corner drags against the frame or floor.

What you need:

• A screwdriver or drill
• 3-inch wood screws (if the original screws are stripped)
• Wooden toothpicks or golf tees and wood glue (for stripped holes)

Steps:

1. Open the door and check each hinge screw by trying to tighten it. Pay special attention to the top hinge, which bears the most weight.
2. If a screw turns freely and will not tighten, the hole is stripped. Remove the screw, dip two or three wooden toothpicks in wood glue, and push them into the hole. Break them off flush and let the glue dry for at least 30 minutes.
3. Drive the screw back in. For a more permanent fix, replace the short factory screw with a 3-inch screw that reaches into the wall stud behind the jamb.
4. Test the door. In most cases, this alone solves the problem.

Fix 2: Realign the Strike Plate

If your door closes but the latch does not catch in the strike plate, the two are no longer aligned. You can confirm this by rubbing lipstick, chalk, or a dry-erase marker on the latch bolt, then slowly closing the door. The mark on the strike plate shows you exactly where the latch is hitting.

If the latch is slightly off (less than 1/8 inch):

• Remove the strike plate and file the opening with a metal file to enlarge it in the direction of the latch mark.
• Reinstall the strike plate and test.

If the latch is more than 1/8 inch off:

1. Remove the strike plate.
2. Fill the old screw holes with toothpicks and wood glue.
3. Mark the new position based on where the latch actually hits.
4. Chisel the mortise (the recessed area in the jamb) to the new position.
5. Drill new pilot holes and reinstall the strike plate.
6. Test the latch. It should click securely into place.

Fix 3: Plane or Sand a Swollen Door

Wood doors absorb moisture and expand. This is particularly common in Los Angeles during the late spring and early summer when coastal fog and marine layer humidity increase. If your door sticks seasonally, swelling is likely the cause.

What you need:

• A block plane or belt sander
• Sandpaper (80-grit and 120-grit)
• Primer and paint to reseal the exposed wood

Steps:

1. Close the door and identify where it rubs by looking for shiny or worn spots on the edge of the door or the frame.
2. If the sticking area is along the latch side, you can often sand it without removing the door. Use a sanding block and work the tight spots.
3. If the sticking is along the top or bottom, remove the door by tapping out the hinge pins with a nail and hammer.
4. Plane or sand the high spots, removing a small amount of material at a time. Check the fit frequently.
5. Once the door closes freely, seal the raw wood with primer and paint to prevent future moisture absorption.

Important: Do not overdo it. Remove only enough material for the door to close with a consistent gap of about 1/8 inch. If you remove too much, the door will have a visible gap when the wood contracts in drier months.

Fix 4: Address Foundation Settling

Many LA homes, especially those built before 1970 in areas like Silver Lake, Echo Park, Highland Park, and the hillside neighborhoods, experience ongoing foundation settling. When a foundation shifts, door frames go out of square, and doors that used to close perfectly start sticking or refusing to latch.

Signs that settling is the issue:

• Multiple doors in the house are sticking, not just one
• You see cracks in drywall near door frames or window corners
• The gap around the door is visibly uneven (wider at the top on one side, narrower at the bottom)

For minor settling, the fixes above (tightening hinges, moving the strike plate, planing the door) will get the door working again. For significant settling, you may need a professional to assess whether the foundation needs repair. A handyman can adjust doors and frames to work within the settled structure, which is often more practical than a full foundation repair.

DIY vs. Professional Cost Comparison

Most door repairs are well within DIY range. But if you have a warped door that needs replacement, multiple doors that need adjustment due to settling, or you would rather not risk damaging the door frame, a professional can get it done quickly.

When to Call a Professional

Some door problems go beyond simple DIY fixes:

• The door is severely warped — A door that is bowed or twisted more than a quarter inch needs to be replaced. No amount of planing will fix a warp that severe.
• The frame itself is damaged or rotted — If the jamb is splitting or the wood is soft from moisture damage, the frame needs repair or replacement before the door will work properly.
• Multiple doors are sticking throughout the house — This points to foundation settling and may require a professional assessment.
• You need a door hung from scratch — Hanging a new pre-hung or slab door requires precise measurements and shimming. Our door and window repair service handles this regularly for LA homeowners.
