How to Repair a Door That Won’t Close Properly (Step-by-Step Guide)

A door that won’t close properly is more than just annoying—it can compromise security, energy efficiency, and peace of mind. Whether your door sticks, sags, or won’t latch, this guide covers quick DIY fixes and when to call a pro.

🔧 Common Reasons a Door Won’t Close (And How to Fix Them)

1. Hinge Problems (Most Common Fix)

Symptoms: Door sags, rubs at the top/bottom, or won’t stay closed.

How to Fix:

✔ Tighten loose screws (Use a screwdriver)
✔ Replace stripped screws (Fill holes with toothpicks + wood glue)
✔ Adjust hinge position (Loosen screws slightly and shift the door)

Pro Tip: If the door still sags, try swapping the top and bottom hinges for better alignment.

2. Swollen or Warped Door (Humidity Damage)

Symptoms: Door sticks in summer but works in winter.

How to Fix:

✔ Sand the edges (Use 80-grit sandpaper where it sticks)
✔ Seal with paint or varnish (Prevents future swelling)

For Severe Warping:

Replace the door (Cost: $150-$500)

3. Misaligned Strike Plate (Door Won’t Latch)

Symptoms: Latch doesn’t catch, or you must slam the door shut.

How to Fix:

✔ Loosen strike plate screws and adjust position slightly.
✔ File the latch hole if it’s too tight.
✔ Use a strike plate extender ($5 at hardware stores).

4. Loose or Broken Door Frame

Symptoms: Door moves when pushed, gaps around the frame.

How to Fix:

✔ Tighten frame screws (Check for stripped holes).
✔ Reinforce with wood shims (For minor shifts).
✔ Replace damaged frame sections (For rot or major cracks).

5. Floor or Threshold Obstruction

Symptoms: Door drags on the floor or carpet.

How to Fix:

✔ Trim the bottom of the door (Use a circular saw or hand plane).
✔ Adjust the threshold height (If it’s too high).
