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

A fan that vents into the attic moves moisture—it does not remove it from the home.

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.
