DifficultyBeginner to intermediate
Time30–90 minutes
DIY Cost$0–$30
Professional Range$125–$300
Safety first: Stop when you encounter energized equipment, structural damage, active water, burning, mold-like growth or conditions outside your experience.

Understand the job

Inspect the reveal and determine which corner is low.

What to inspect first

Tighten hinge screws without stripping them.

Step-by-step approach

Replace one jamb-side screw with a longer structural screw into framing when appropriate.

Common warning signs

Check hinge leaves for bending or wear.

Final checks

Reassess latch alignment only after the door hangs correctly.

Tools and materials to plan for

The exact list depends on the product and site, but plan for measuring tools, suitable personal protection, manufacturer-approved fasteners or fittings, cleanup supplies and a reliable way to verify the finished work.

Common mistakes to avoid

  • Replacing parts before identifying the cause
  • Skipping measurements and product instructions
  • Using materials not rated for the location
  • Closing the repair before checking hidden damage
  • Failing to test the completed work
Tony’s Pro Tip

Do not start by cutting the door. Hinge correction often restores the original alignment.

Should you DIY or hire help?

A careful homeowner can often handle straightforward maintenance and replacement work. Hire help when access is difficult, hidden damage appears, permits or licensing may apply, or the repair crosses into structural, electrical, roofing or plumbing systems that require specialized experience.
