Detect and fight mold in your home – Andy Bell of Handyman Matters introduces us to Pierre from Mold Dog Mold Detection in an effort to find the source of mold growing inside a Colorado home. Raleigh, the mold sniffing Australian Sheppard, is trained to sniff out 17 different species of mold. Once the mold is detected, a handyman or contractor can take steps to remove the mold and seal the area without inflicting major damage on the home. Hot spots for mold include the space under the sink in the kitchen and bathrooms, near the refrigerator, and near houseplants.
