Mold is sneaky. It doesn’t always grow where you can see it, and by the time you smell that musty odor or see dark spots, it’s often already spread behind walls, under floors, or into your HVAC system. Whether it’s from past water damage, everyday humidity, or a hidden leak, mold can grow anywhere moisture lingers. Knowing the most common places mold likes to grow in your home can help you catch it early — or even better, prevent it entirely.

At A+ Restoration, we help homeowners in Covington, KY and surrounding areas identify and safely remove mold with our professional mold remediation services. Below are the top mold-prone areas you should keep an eye on.

1. Basements and Crawl Spaces: Mold’s Favorite Hiding Spot

Your basement or crawl space is dark, damp, and often poorly ventilated — basically the perfect environment for mold. Whether it’s from past flooding, leaky foundations, or condensation, moisture easily collects in these areas.

Common signs of mold in basements:

  • Musty or earthy smells
  • Dark or greenish-black spots on walls or floors
  • Crumbling drywall or peeling paint

What you can do:

  • Install a dehumidifier
  • Seal any foundation cracks
  • Improve ventilation

PAA: Why does mold grow in basements?
Mold thrives in humid, low-light environments. Basements tend to hold moisture and often have poor airflow, creating the perfect storm for mold growth.

If you suspect basement mold, A+ Restoration provides mold testing and remediation to stop it at the source.

2. Bathrooms: Warm, Wet, and Mold-Friendly

Bathrooms are ground zero for daily moisture. Hot showers, steamy mirrors, and dripping faucets add up fast — and without proper ventilation, mold will find its way in.

Mold-prone bathroom spots:

  • Shower walls and caulking
  • Under sinks and behind toilets
  • Bathroom ceilings and corners
  • On tile grout

How to prevent it:

  • Always run your exhaust fan during and after showers
  • Wipe down wet surfaces
  • Fix leaky plumbing quickly

PAA: How do I get rid of mold in the bathroom permanently?
It starts with addressing the moisture problem. Mold removal combined with improved ventilation and routine cleaning is the best long-term solution.

3. Attics: Hidden Mold Above Your Head

Out of sight, out of mind — that’s why attic mold can go unnoticed for months or even years. Leaky roofs, poor insulation, and inadequate ventilation often lead to condensation, which feeds mold.

Watch for these attic warning signs:

  • Discolored insulation
  • Black spots on wood beams
  • Wet patches on the underside of the roof
  • Increased allergy symptoms indoors

Preventative steps:

  • Make sure your attic is properly ventilated
  • Repair roof leaks immediately
  • Check for mold at least twice a year

PAA: Can mold in attic make you sick?
Yes. Mold spores can circulate through your HVAC system and affect indoor air quality, leading to respiratory issues, fatigue, or allergic reactions.

4. Kitchens and Under Appliances: Mold’s Stealth Mode

Your kitchen may be clean on the surface, but mold can lurk underneath or behind appliances where small leaks go unnoticed for months.

Top mold spots in the kitchen:

  • Under the sink
  • Behind the refrigerator
  • Around the dishwasher
  • In pantry corners or dark storage cabinets

How to stay ahead of it:

  • Check for leaks regularly
  • Clean behind and under appliances at least every few months
  • Use exhaust fans to reduce humidity while cooking

PAA: What causes mold under kitchen sinks?
Usually it’s a slow drip from your plumbing or faucet that goes unnoticed. The enclosed space allows moisture to build up and mold to thrive.

A+ Restoration offers full water and mold damage cleanup for homes and kitchens affected by hidden leaks.

5. HVAC Systems and Air Ducts: Mold in Your Airflow

Mold in your heating and cooling system is a silent threat. It can spread spores throughout your home and trigger allergies, asthma, and other health problems.

Where mold hides in your HVAC:

  • Inside ducts and vents
  • Around the AC drip pan or coil
  • In the furnace or air handler
  • On air filters

Prevent mold in your HVAC by:

  • Changing air filters every 1–3 months
  • Cleaning drip pans and coils
  • Scheduling regular duct inspections

PAA: How do I know if there’s mold in my air ducts?
Signs include a persistent musty smell when the system runs, visible mold around vents, and increased allergy symptoms at home.

Don’t wait to breathe easy again. A+ Restoration can inspect your HVAC system and remove mold before it spreads.
