How Often Should Shower Silicone Be Replaced?
Why shower silicone should be replaced according to its condition, not a fixed calendar.
Is there a fixed replacement interval?
No. There is no universal rule requiring shower silicone to be replaced every year. Its service life depends on the product, preparation, movement, use, cleaning and ventilation. Inspect it regularly and replace it when its condition warrants.
Signs to look for
Check for peeling, splits, gaps, loss of adhesion, persistent staining and water tracking outside the shower. Surface mould alone does not always mean the seal has failed.
What happens during replacement?
Where appropriate, the old silicone is cut out, the joint is cleaned and dried, and a compatible sanitary sealant is applied. Persistent leaks should be investigated rather than assumed to be a silicone issue.
