Can mold grow behind drywall?

Mold can grow behind drywall, in your attic, in the basement, under floors — mold can grow anywhere. The key to controlling mold is controlling moisture and water. If your home has been exposed to excessive water due to flooding or heavy rains, if you have an old home with leaky pipes, or if you live in an area with high humidity, you need to be vigilant about mold. Mold is most easily identified by sight. You may see blooms of mold on furniture, on walls, or along the floor. If you can spot mold, you probably don’t need to test for it and can save on mold inspection costs and direct your energies towards mold remediation. But if you’re not certain, you may need a pro to help you determine whether you have hidden mold. Scent and illness are two potential signs of hidden mold. You may smell anything from a musty earth scent to a foul stench, and you may experience respiratory problems, nasal and sinus congestion, eye irritation, nose or throat irritation, skin irritation, problems with your nervous system, or aches and pains. The national average cost of mold inspection and testing is $250-$300.
