Common warning signs

If leakage or odor is present, remove the toilet and inspect the flange and seal.

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

A rocking toilet can break the seal even when no water is visible yet.

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.
