Stop the Mold Before it Grows
Breathing a strong, earthy, musty smell might be appealing when hiking through the forest, but that odor in a living room is another story.
Mold has grown on earth since the proper conditions allowed it to spawn, and homes have sometimes become hosts for its breeding grounds.
Moisture, warmth and food is all mold needs to grow. Spores can take hold in temperatures between 40 to 100 degrees Fahrenheit and will usually multiply within 48 hours.
“Mold can thrive at about 10% relative humidity,” said Maggie Michel, President of Air Fresh Environmental (AFE). “On a dry day in Tucson we will still be at about 22% relative humidity.”
AFE specializes in helping people clean the air in their homes by offering testing services and air purifiers. Michel also provides preventative measures for builders and homeowners.
“Be proactive,” said Michel, a SAHBA member. “Look under sinks and even pictures on the walls. Most of all don't cover up a musty smell with a plug-in or spray.”
Detecting mold can be tricky because some people experience little or no reaction from high levels of exposure. Mold hides and often times never appears in plain view. Even the cleanest homes may have mold in the walls, said Michel.
Mold spores are all around, but growth of these microscopic particles inside the home can be prevented. Using area rugs instead of wall-to-wall carpeting allows homeowners to clean under floor coverings.
Ventilation is important to take away the moisture mold needs to thrive. Use an exhaust fan or window in areas where moisture is produced. Michel stresses that while circulation will help stop a build up of moisture, purification is needed to prevent mold.
Also, keep gutters and downspouts free of debris to prevent water from being stored on the roof. Water can be moved away from the base of the home by extending downspouts or adjusting landscaping.
Early detection makes controlling mold easier and potentially cheaper. Take action if a musty smell pops up after any water-related problems.
If mold continues to grow on a surface after it has been cleaned, there is probably a colony of mold multiplying below. Because some mold can give off deadly neurotoxins, consult a professional about clean up.
