How to Repair Common Door Problems: A Homeowner’s Guide
Doors are essential features in every home, providing privacy, security, and style. Over time, interior and exterior doors can experience a wide range of issues—from sticking, squeaks, and loose hinges to damaged locks and misaligned latches. Fortunately, most door problems are easy to diagnose and fix with a few basic tools and some know-how. This comprehensive guide offers step-by-step advice on repairing the most common door problems so you can restore function and improve comfort without costly replacements.
What You’ll Need for Door Repairs
- Screwdrivers: Both flathead and Phillips
- Wood filler or epoxy
- Hammer and rubber mallet
- Sandpaper (medium and fine grit)
- Utility knife
- Chisel
- Drill with bits
- Level
- Lubricant (white lithium grease or silicone spray)
- Replacement screws and hardware (hinges, locks, latch plates)
- Paint or stain (if needed)
Diagnosing Common Door Problems
Before starting any repairs, identify the exact problem with your door. Ask yourself:
- Does the door stick, scrape, or not close properly?
- Are there loose or squeaky hinges?
- Is the door lock or latch not functioning?
- Does the door sag, swing open, or not stay latched?
- Are there visible cracks, splits, or surface damage?
Once you’ve identified the issue, refer to the specific repair instructions below.
How to Fix a Sticking or Binding Door
Doors that stick or don’t close smoothly often result from humidity, house settling, or misaligned hardware. Follow these steps:
- Identify where the door sticks: Close the door slowly and observe where it rubs against the frame.
- Tighten all hinge screws: Often, loose hinges cause the door to drop and bind. With a screwdriver, tighten all hinge screws on the door and frame.
- Replace stripped screws: If a screw turns but does not tighten, remove it and insert a longer screw or fill the hole with wood glue and matchsticks, then reinsert the screw.
- Adjust the hinges: Moving the top hinge slightly inward can pull the door away from the frame’s top (reduce sticking at the top); moving the bottom hinge can address sticking near the bottom.
- Sand the sticking edge: If tightening hardware doesn’t solve the issue, lightly sand the sticking edge with medium-grit sandpaper. Test frequently and remove only as much wood as needed. Repaint or refinish sanded edges.
Tip: For painted doors, scrape away paint buildup at the sticking points before sanding.
How to Fix Squeaking Doors
Squeaky doors can be annoying but are easy to fix:
- Lubricate hinges: Apply a small amount of white lithium grease or silicone spray directly to the hinge pin and joints.
- Move the door: Open and close the door several times to work the lubricant into the hinge.
- Remove and clean hinge pins (if squeak persists): Tap out hinge pins with a hammer and small nail. Clean them with steel wool, then apply lubricant before reinserting.
Repairing Loose Hinges or Door Hardware
Loose hinges cause sagging, sticking, and improper latching. Here’s how to repair them:
- Tighten screws with a screwdriver or drill.
- If the screw holes are stripped, remove the screws and fill the holes with wood glue and wooden golf tees or matchsticks; break them off flush, let dry, and reinsert screws.
- For extra strength, use longer screws that reach into the door frame studs.
- If hinge leaves are bent, replace the hinge with an identical new one.
How to Fix a Door That Won’t Close or Latch
If your door won’t latch, check these possible causes:
- Misaligned strike plate: If the latch does not align with the hole in the strike plate, move the plate up, down, or sideways as needed. Fill old holes with wood filler and drill new pilot holes for screws.
- Sticking latch: Lubricate the latch mechanism with a dry lubricant. If the latch is bent or broken, replace it.
- Door misalignment: Adjust hinges or sand the door as described above.

Repairing Cracked or Damaged Doors
Cracks or splits in doors are usually the result of impact damage or dryness. To repair:
- Clean out any loose or splintered material from the crack with a utility knife.
- Apply wood glue into the crack, then clamp the area until dry (typically 24 hours).
- For deep cracks or missing wood, fill the area with wood filler or two-part epoxy. Let dry, sand smooth, and refinish as needed.
If there is major structural damage, such as large splits or rot in exterior doors, consider replacement for safety and security.
How to Fix Holes or Gouges in Doors
- For solid wood doors, fill small holes or gouges with wood filler. Let dry, sand, and touch up with matching stain or paint.
- For hollow core doors, fill larger holes using a piece of rigid foam or wood as backing. Insert behind the hole, then fill with lightweight spackling or filler. Sand and repaint.
Repairing Sliding or Pocket Doors
Sliding and pocket doors, often used for closets or space-saving room dividers, can also develop issues over time:
- Sticking or hard to open: Clean the track and rollers. Remove debris, lubricate the track with silicone spray, and check for bent rails.
- Derailment or wobbling: Realign the rollers by tightening adjustment screws (usually located at the base of the door).
- Cracked or damaged tracks: Replace damaged sections according to the manufacturer’s instructions.
Repairing Exterior Door Problems
Exterior doors are exposed to the weather and can experience these specific issues:
- Drafts or air leaks: Replace or reposition weatherstripping along the doorstop and threshold. Inspect and adjust the door sweep (the rubber strip at the bottom).
- Swollen doors: Use a dehumidifier or air conditioner to manage moisture indoors. Sand sticking edges sparingly, as over-removal may worsen drafts.
- Rusty hinges: Remove rust with a wire brush, then lubricate or replace hardware as needed.
- Rot or water damage: Scrape away soft, wet wood, fill the area with wood hardener and filler, then repaint to seal out future moisture.
Fixing Door Locks and Latches
Locks and latches can fail for several reasons, making doors difficult or impossible to secure:
- Key won’t turn: Apply graphite powder or lubricant to the lock cylinder. If unsuccessful, remove the lock and inspect for worn or broken parts.
- Loose lockset: Tighten mounting screws on the knob, lever, or deadbolt inside and outside the door.
- Sticky lock: Clean out the lock with compressed air; lubricate lightly.
- Broken latch or lock: Replace the lockset with a new model; follow package instructions for installation.
Tips for Regular Door Maintenance
- Check hinges and hardware annually; tighten loose screws and lubricate moving parts.
- Touch up paint or varnish on exterior doors to prevent rot or warping from moisture.
- Inspect weatherstripping and replace when worn to save on energy bills and increase comfort.
- Clean door surfaces regularly with mild detergent; avoid abrasive cleaners that may wear finishes.
- Use a level to periodically check that doors remain square in the frame, especially after flooding or foundation shifts.
Table: Common Door Problems and Solutions
| Problem | Possible Cause | DIY Solution |
|---|---|---|
| Sticking door | Humidity, misaligned hinges, paint buildup | Tighten hinges, sand sticking edge, remove excess paint |
| Squeaky hinges | Lack of lubrication, dirt buildup | Clean and lubricate hinges, remove pins for deep cleaning |
| Won’t latch | Misaligned latch plate/strike, warped door | Adjust strike plate, tighten/replace hardware, sand edge |
| Drafts | Poor weatherstripping, warped door | Replace weatherstripping, adjust threshold, repair sweep |
| Loose lock | Stripped screws, worn parts | Tighten/reinsert longer screws, replace lockset if needed |
When to Call a Professional
- The door is badly cracked, split, or rotten and may compromise security.
- Major structural problems exist, such as doors no longer fitting their frames due to shifting foundations.
- Repair requires specialized tools or knowledge (e.g., mortise lock installation, realignment of heavy exterior doors).
- You feel uncomfortable or unsafe handling the repair yourself.
Frequently Asked Questions (FAQs)
Q: What causes a door to stick suddenly?
Seasonal humidity often causes wood to swell, resulting in sudden sticking—especially with older wood doors. Settling of the house, loose hinges, or paint buildup can also contribute.
Q: How do I know if my door needs to be replaced instead of repaired?
Replace your door if it is severely warped, cracked, weather-damaged, or if repairs would cost more than half the price of a new door.
Q: What’s the best lubricant for door hinges?
Use a silicone spray or white lithium grease for long-lasting, mess-free lubrication. Avoid oil-based lubricants, which attract more dust and dirt.
Q: How can I stop drafts from coming under my exterior door?
Install or replace the door sweep at the bottom and add new weatherstripping along the sides and top as needed.
Q: Is it possible to repair a hollow core door with a large hole?
Yes. Reinforce large holes with foam or wood backing, then use lightweight filler, sand smooth, and repaint for a seamless finish.
