Landlords, Tenants, & Employers

1. Airborne mold spores are everywhere both indoors and outdoors. Texas
residents and employees’ health is at serious risk if there are elevated
levels of mold spores indoors, as compared to an outdoor mold control test,
in Texas homes and workplaces.
2. The most dangerous indoor molds are
Alternaria, Aspergillus, Chaetomium, Cladosporium, Fusarium, Mucor,
Penicillium, and Stachybotrys. Mold testing and mold laboratory analysis are
required to identify specific mold species. See
mold pictures and detailed information on the most
dangerous mold species.
Molds spores can cause serious health problems even if the spores are dead
or dormant (inactive while waiting for more moisture to resume growth). Even
the smell of dead or dormant mold can make some mold-sensitive persons ill.
impossible to get rid of all mold spores indoors. Some mold spores will
always be present in house dust and floating in the air.
mold spores will not grow into mold colonies if there is insufficient
moisture. Indoor mold growth can and should be prevented or controlled by
controlling moisture indoors. If organic materials are wet for more than 24
hours, mold growth can begin.
Mold grows by eating and destroying organic building materials
and other cellulose-based materials such as carpeting, upholstery, and
clothing. The longer that mold grows, the more mold damage to the building.
Cellulose is the main substance in the cell walls of plants (and thus of
wood), and it is used in the manufacture of many organic building materials
such as drywall, plasterboard, plywood substitutes, and ceiling tiles.
Mold can grow hidden and undetected inside wall and ceiling cavities;
beneath wallpaper, paneling, and carpeting; and inside heating and cooling
equipment and ducts, attics, crawl spaces, and basements.
growth is often the result of a structural or construction defect, or of
maintenance neglect, that allows moisture to enter the building.
10. The owner or employer must first fix the water problem (roof leak,
plumbing leak, high indoor humidity) that enables the mold to grow.
mold remediation requires killing the mold with a
mold home remedy, removing it, and treating the cleaned area with an
mold home remedy.
