Spotting worn caulk around a tub or sink
Caulk seals small joints around many tubs and sinks. Cracks, separation or persistent dampness are signs it needs attention.
What you can check
- 01
Inspect the joint in good light for gaps, cracks or caulk pulling away from the surface.
- 02
Keep the area as dry as practical and look for soft trim, staining or water on the other side of the wall.
- 03
Take a photo of the affected joint and note whether it is getting worse.
Safety first
Do not cover an active leak or persistent dampness with fresh caulk. Suspected mold or damaged backing may require specialist assessment.
When to ask for help
Ask for help replacing deteriorated caulk or investigating water that appears beyond the joint.
