Did you know... The silicone in the corner of your showers only last 3 to 5 years depending on use and a couple other factors. This needs to be replaced periodically to ensure there's no leaks and no buildup of mold or mildew in the crevices of your shower.
Signs it is time to replace your silicone: homeowners should periodically check the corners for these warning signs:
Separation: The silicone bead is visibly pulling away or lifting from the composite panel.
Texture Changes: The sealant feels brittle, crumbly, or overly hard to the touch.
Persistent Discoloration: Black or dark green mold spots are spreading underneath or through the clear/colored silicone bead.
When replacing the bead, always completely scrape away the old material and clean the seam thoroughly before applying a fresh line of high-quality, mold-resistant 100% kitchen and bath silicone.
Key Factors Affecting Lifespan of silicone
Ventilation: Bathrooms that remain damp for extended periods place extra stress on the sealant. Proper airflow extends the life of the corner joints.
Usage Frequency: A primary family shower will experience faster silicone degradation than a rarely used guest bathroom.
Cleaning Habits: Harsh abrasive chemicals or bleach can break down the integrity and mold-resistant properties of the silicone prematurely.
Structural Movement: The natural expansion and contraction of your home's walls put mechanical stress on the inner corner seams.
