AvatarByMahlon Boehs General Wood Topics

Mold can be a persistent and unwelcome guest in our homes, often appearing in the most unexpected places. Among its favorite hiding spots is wood, which can absorb moisture and create the perfect environment for mold to thrive. Whether it’s an antique piece of furniture, wooden beams in your basement, or even outdoor decking, the presence of mold can not only compromise the beauty of the wood but also pose health risks to those living in the space.
