Shower Drain is developing lots of embedded mold around drain seal. Whats needed to prevent a leak from developing?
My Shower drain appears to be developing mold around the seal. house is about 12 years old
Can i cut away / clean the mold and re apply an external bead of silicone? or do i need to replace the drain seal?
I do not have access to the underside of my shower, so not sure how easily it would be to replace the shower drain seal
thanks
