Preventing water damage inside our bathrooms is as important as directing water away from the foundation. As part of your routine home-owners maintenance, you should inspect the caulking in tubs, showers and vanities for cracking.
If cracks are left unrepaired with the high humidity in your bathroom, it can become an open invitation for mould and mildew to grow, often out of sight. To prevent this, immediately remove any damaged caulking (showing signs of cracking or gaps) and replace it with new caulking.
Remember proper maintenance of the caulking is much less expensive than the costly repairs that may be necessary if you sustain water damage.
