Bathroom Mold Inspection Steps
Bathroom mold can result from several
different water intrusion problems, including: (1) leaky water supply and
water drain pipes both visible and hidden beneath a bathtub and in shower
walls and bathroom walls;
(2) elevated humidity (above 70%) from the combination of taking baths and
showers with inadequate room ventilation to get rid of the humidity, e.g.,
the lack of a strong bathroom exhaust fan that exhausts the humid bathroom
air directly to the outdoors.
Bathroom mold inspection is effective when you utilize these inspection
steps: (1) close visual inspection of all surfaces in the bathroom for water
problems and mold growth; (2) careful visual inspection inside all areas of
the sink cabinet; (3) using a professional quality moisture meter to scan
the floor, walls, and ceiling for elevated levels of hidden moisture;
(4) visual inspection for mold inside bathroom exhaust register, fan, and
duct; (5) fiber optics inspection inside shower and bathroom walls (because
of tiling of shower and walls, it is usually best to cut the fiber optics
cable entry holes into drywall on the back side of the walls); and
(6) surface sampling for deposited/landed mold in out of the way places such
as on the top of the inside bathroom door trim.
Check to make sure that the bathroom's exhaust fan is actually exhausting
the humid bathroom air directly to the outdoors and not to the inside of a
wall, ceiling, or attic, wherein the unfortunate result would be significant
hidden mold growth.
In addition, do
mold testing of the bathroom air,
and of the outward air flow from the bathroom heating and cooling duct
register to determine if there are elevated levels of airborne mold spores.
