Is it time to replace?

• Common Symptoms: Leaking seams, dried-out clear sealant, or flexible joints that need resealing after movement or moisture exposure.
• Visible/Sensory Cues: Cloudy or separated silicone, missing bead sections, water tracks, or gaps at the repair joint.

Pro Tip: Allow trapped moisture to dry out before resealing, or even a good silicone bead can fail early.
