The Fix-It Playbook — Cracked or Moldy Caulk Flowchart | Free 1-Page PDF | 2026 Edition

Caulk at the tub cracked, peeling, or moldy? Check the wall before you reach for the tube.

Two questions sort it. Does the wall behind the tile feel solid — soft spots, loose tiles or an active leak mean a pro first. Then: is this the first recaulk on that joint, or has new caulk already failed there? First time means strip, prep and reseal; failed again means the sheet finds out why.

The sheet also carries caulk vs grout (flexible seal vs rigid filler), and a plain line on when to stop and call a pro.

One page. Print it or keep it on your phone. Free instant PDF download, yours to keep.

If the tree sends you deeper: How to Recaulk a Tub or Shower ($6) adds the complete 8-step walkthrough, the full troubleshooting table, and the habits that keep new caulk from failing. All five bathroom guides come together as the Bathroom Repair Kit ($14), and all 24 year-round guides are in the Core Library ($49).
