Bathroom Mould Growth & Problems

[June 25, 2003]

Q. I have a bath with black all around the tub and underneath the caulking.  I have removed and cleaned twice and it keeps coming back. Now that I have read all the side effects to mould, I think I might have an allergy to it. Is there someone in the St. Louis area that is in the "mould business"? Also does your do it yourself test kits include the dangerous black mould test?

A. You may have a water leak INSIDE your bathroom wall or floor that enables the mould to grow and to keep re-appearing. Alternatively or in addition to a water intrusion problem, you may also have too high a humidity in the bathroom [above 60% humidity level enables mould to grow], thus enabling mould to grow.. During and after tub baths and showers, you should be running an exhaust fan that exhausts the humid bathroom air directly to the outside. Be sure your bathroom and kitchen exhaust fans exhaust air directly to the outside and NOT [as is frequently found] into wall cavities, floor cavities,  the attic, the basement, or into a crawl space. Exhaust fans can put large amounts of moisture-laden air into such areas, and thus cause serious mould growth and problems. You may mould growth INSIDE or BEHIND your bathroom walls, ceilings, and walls, in which you will need to locate and to remove such bathroom moldy building materials, treat the cleaned out areas with antimicrobial coating.  Our do it yourself mould test kits with our expert mould laboratory analysis can collect mould samples for accurate mould identification of all types of mould species, including black mould (Stachybotrys mould).
