In Seattle, our damp weather can turn our homes into veritable petri dishes for mold. In this post, I will explain some common-sense precautions you can take to prevent this potentially toxic organism from proliferating in your home and some possible solutions if you do find black spots on your walls.
The first step in preventing and eradicating mold is to know what you're dealing with. Mold is not a plant. Rather, mold is a non-scientific term describing various fungi. Mold doesn't care for sunlight and can only reproduce in damp conditions.
Mold spores are everywhere around us, and mold provides many useful functions, like breaking down fallen leaves. Most mold doesn't pose a risk to healthy people, but the Washington Department of Health cautions:
People who have allergies or asthma may be more sensitive to molds. Sensitive people may experience skin rash, running nose, eye irritation, cough, nasal congestion, aggravation of asthma or difficulty breathing. People with an immune suppression or underlying lung disease, may be at increased risk for infections from molds. A small number of molds produce toxins called mycotoxins. When people are exposed to high levels of mold mycotoxins they may suffer toxic effects, including fatigue, nausea, headaches, and irritation to the lungs and eyes.
If you suspect you might be experiencing adverse health effects from mold, you should see your doctor.

In most cases, you don't need to sample for mold because you can smell it and see it. If you see white or black spots on your walls, you know you have a mold issue. But even if you don't see it, it may still be lurking in your home. A musty smell indicates that you might have mold growing behind the walls or wallpaper, under your carpet, or on the back of ceiling tiles. Here are some common places mold grows in homes:
Because mold spores are everywhere, the only effective prevention is to eliminate the conditions in which mold thrives. That means tackling moisture problems before they start growing mold.
If you do find mold in your home, don't panic. It's a common problem affecting more than 70% of homes nationwide. In many cases you can clean up the mold yourself. The EPA states that if the area affected is less than 10 square feet, you can probably handle the cleanup yourself. If your problem is bigger, you may want to consider enlisting the services of a mold remediation company that has the equipment and the expertise to effectively and safely remove and clean mold-damaged materials. Remediation generally follows these steps:

Estimates vary widely, and actual cleanup costs depend on the size of the affected area, the level of contamination, the extent of the damage. However, Moldblogger estimates the cost to be anywhere from $500 for a small crawl space to $30,000 or more for a home that has been in a major flood. Fixr estimates the average to be $2,000 - $6,000.
