That faint, musty odor in your home could be more than just “old house smell.” It could be mold—growing behind walls, under flooring, or inside your HVAC system. If left untreated, mold can damage your property and negatively affect your health.
Here’s how to spot early warning signs and take smart action before the problem gets worse.

1. Musty or Earthy Odors
Mold often produces a distinct smell that intensifies in enclosed or humid spaces. If you notice a lingering odor in one area—especially bathrooms, basements, or laundry rooms—it’s time to investigate further.
2. Visible Discoloration
Mold may appear as black, green, or white patches on drywall, ceilings, or wood. Sometimes it looks powdery; other times, it appears slick or fuzzy. These stains may be small, but they indicate a larger hidden issue.
3. Recent Water Damage or High Humidity
If you’ve had a leak, flood, or excess condensation recently, you’re at higher risk. Mold thrives in damp environments, and it only takes 24 to 48 hours for colonies to form after water exposure.
4. Health Symptoms at Home
If you or your family members experience frequent coughing, sneezing, sinus irritation, or skin rashes indoors, mold could be a contributing factor—especially if symptoms improve when you leave the house.
5. Ineffective DIY Solutions
Over-the-counter sprays and bleach wipes may clean visible mold, but they don’t eliminate spores in the air or inside porous materials. In some cases, they can even make the problem worse by spreading the spores.
What to Do If You Suspect Mold
The smartest move is to schedule a professional mold inspection. Certified technicians use moisture meters, air sampling, and thermal imaging to identify mold growth accurately and recommend safe removal strategies.
