Mold and mildew problems are common in areas with high moisture. When left unaddressed, the tell-tale black or gray splotches can rapidly spread out of control. Mold will damage your health and your home. When you see any of these warning signs, it's important to act quickly so the damage doesn't spread.

• Musty smells. A musty odor in your basement, attic, or crawl space is often the first sign of a mold or mildew problem, so let your nose be your guide.

• Water leaks. Damp spots on the walls or ceilings could be signs of water leaks, and if left unaddressed, they could lead to mold and mildew.

• Discolored paint. When mold and mildew start to take hold, you may notice discoloration and staining on your walls. Any discoloration should be cause for concern.

• Dark stains. The presence of dark stains in your bathroom, especially on the tiles, is a common early warning sign of mold and mildew.

• Mold-related health issues. Mold exposure symptoms include sudden wheezing, coughing, itchy or watery eyes, and unexplained rashes.

• Dampness. A damp basement can predispose your home to mold and mildew, which is especially likely if your basement has flooded in the past. Take steps to check for contamination before it spirals out of control.

• Standing water. The presence of standing water around your home can also predispose the property to mold and mildew. Look for ways to improve drainage, and check for puddles and other standing water after heavy rain.

The sooner you address a mold or mildew problem, the easier it will be to fix. If you suspect the problem is already beyond your control, your next phone call should be to a mold remediation expert.
