Caulking in areas exposed to moisture—such as bathrooms, showers, and around windows—should typically be replaced every 1 to 3 years, depending on the level of humidity, water exposure, and overall wear.
If you notice cracking, discoloration, mold, or peeling, it’s a clear sign that the silicone is no longer providing a proper seal and should be replaced immediately. Regular caulking replacement helps prevent water leaks, mold growth, and structural damage, keeping your home protected and energy efficient.
