Caulk peeling or molding around the tub

Honest verdict: you can likely DIY this$0–$250Typical repair cost
Likely causes, most common first
- Old caulk reaching end of life (5–10 years is normal)
- Wrong caulk type used (painter's caulk in a wet zone)
- Movement between tub and tile breaking the seal repeatedly
Do this right now
- Remove all old caulk fully (razor + remover gel) — never caulk over caulk
- Fill the tub with water BEFORE caulking so the joint is caulked at its widest
- Use 100% silicone labeled kitchen & bath
DIY or call a pro?
A careful homeowner can do this well. Call a pro if the gap keeps reopening within months (movement issue), or if the tile behind feels loose — that's a wall problem wearing a caulk costume.
