If you notice a wet stain or dark spots on walls, ceilings, roofs, or pipes, especially in an area that’s suffered water damage, it could be mold. Mold is particularly fond of dark, cool, and humid areas such as basements and is generally first identified by its musty scent. Another indicator of mold presence is an increase in allergic reactions, cold symptoms, or respiratory issues among your employees. If you suspect there is mold in your building, contact the professionals at Cotton GDS for mold removal.
