Signs of Mold After Water Damage

Mold can begin growing within 24–48 hours after a leak or flood. Spotting the warning signs early helps protect your family’s health and prevents major remediation costs.

1. Musty, Earthy Odors

A persistent damp smell—especially in basements, bathrooms, or closets—often points to hidden mold growth.

2. Discolored Walls or Ceilings

Black, green, or brown spotting on drywall, wood, or grout is a red flag, particularly in areas that were recently wet.

3. Increased Allergy or Respiratory Symptoms

Indoor sneezing, coughing, scratchy throat, or headaches that improve when you leave the house can indicate mold exposure.

4. Peeling or Bubbling Paint

Moisture trapped behind walls weakens paint adhesion, causing bubbling, cracking, or peeling.

5. Warped, Soft, or Damp Surfaces

Spongy drywall and warped trim suggest ongoing moisture—ideal conditions for mold to thrive.

Act Quickly to Protect Your Health

The sooner you investigate and dry affected areas, the easier it is to stop mold from spreading.
