Mold isn’t always visible, but it can quietly damage your home and impact your health if left unchecked. At Pro Mold Check, we often find that homeowners don’t realize how early mold growth can go unnoticed. Here are five common warning signs that mold may be present in your home — and what steps you should take next.
1. A Persistent Musty Odor
If your home has a lingering earthy or “musty” smell, especially in basements, bathrooms, or crawlspaces, mold could be the culprit. Mold releases microbial volatile organic compounds (MVOCs), which create that signature smell.
What to do: Don’t ignore odors — schedule an inspection or air quality test to confirm the source.
2. Visible Spots or Stains
Mold can appear as black, green, or even pink patches on walls, ceilings, or around windows. Sometimes, it looks like dirt or smudges, but it spreads quickly.
What to do: Clean small areas with proper protection, but widespread or recurring growth requires professional testing and remediation.
3. Allergies That Worsen Indoors
Sneezing, itchy eyes, coughing, or worsening asthma symptoms when you’re at home can be a red flag. Common molds like Cladosporium and Aspergillus are known allergens.
What to do: Track when symptoms flare up. If they improve when you’re away from home, it’s time to get your air quality checked.
4. Water Damage or Moisture Issues
Leaking roofs, plumbing problems, or condensation around windows create the perfect environment for mold. Even after repairs, leftover moisture can lead to hidden growth inside walls or under flooring.
What to do: Address leaks quickly and consider a professional moisture assessment to catch hidden mold.
5. Peeling Paint or Bubbling Walls
When paint starts to crack, peel, or bubble, it’s often a sign of trapped moisture — and mold may be growing behind the surface.
What to do: Don’t just repaint. Investigate the underlying cause to prevent ongoing mold growth.
Why Acting Quickly Matters
Mold doesn’t just threaten your property — it can impact your health. Exposure to certain mold types, like Stachybotrys (often called “black mold”), has been linked to respiratory problems, headaches, fatigue, and other health concerns.
The longer mold goes untreated, the more expensive and disruptive the cleanup becomes.
