Understand the job

Choose a fixture listed for the exposure level.

What to inspect first

Turn off and verify power.

Step-by-step approach

Inspect the electrical box and mounting block for rot, corrosion or looseness.

Common warning signs

Connect grounding, neutral and switched conductors according to verified wiring.

Final checks

Seal the top and sides where appropriate while leaving intended drainage paths open.

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 caulk the bottom edge unless the fixture instructions require it. Trapped water needs a place to drain.

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.
