I found mold in the shower/bathtub caulking – what should I do?

If mold is visible on the caulking in the shower or bath tub, then that immediately tells us that the wrong type of caulking was used.

Caulking is for baseboards and interior doors – not for bathrooms or kitchens where moisture is present.

Bathrooms and showers will always have moisture due to their nature, and therefore require 100% silicone to be used instead of caulking. Silicone is not organic and therefore is not a food source for mold. Caulking on the other hand is a food source for mold.

Silicone is mold and mildew proof and most manufacturers guarantee it. Here is one product we recommend.

So what is the solution?

We recommend removing the caulking and replacing it with silicone. This is a relatively simple process and we do not recommend hiring a mold removal company to do this. In fact, here is a simple step-by-step guide that will show you how to do this:

What you should not do

• Paint over it- giving more moisture and food for mold to grow
• Bleach it- does not kill embedded mold just discolours the surface of it
• Use vinegar- does not kill just discolour it
• Not do anything- this is the worst option of them all! Mold will continue to grow and possibly spread to other areas of the bathroom.
