Wet basements and crawlspaces are mold’s playground. If you’re experiencing allergy symptoms, you should probably investigate your basement and crawlspaces–or have it done for you–to see if hidden moisture has provided a breeding ground for mold. Mycotoxin exposure is not good for your health.
Standing water and moisture must be eradicated if you want to live in a healthy environment. Consider a variety of solutions if you find water–remediation should include removal of all water-damaged building materials, repair and prevention of leakage, a vapor barrier that prevents condensation and construction of top of the line materials that exceed state and local standards.
