Situation snapshot

Start with safety and source control. Then work through what can dry, what needs removal, what should be documented, and where professional mitigation or remediation should take over.

Action order

Move through it in the right sequence.

  1. 01Check grout, transitions, baseboards, and rooms below.
  2. 02Do not assume tile blocks water from spreading.
  3. 03Dry the assembly based on what is beneath it.
  4. 04Repair failed seals only after moisture is controlled.

Risk check

What changes the seriousness.

Watch for

Loose tile, hollow sounds, odor, subfloor softness, or ceiling stains below.
