When Mold Hides in Plain Sight: Unexpected Places Mold Grows in Homes

When Sarah H., a homeowner in Charlotte, Greensboro, smelled a musty odor in her hallway, she figured it was from her kids’ soccer gear or residual dampness. The odor intensified over a period of three weeks, and her son was experiencing allergic symptoms, which concerned her and prompted her to call All Brothers Restoration for a mold inspection.

The issue: An innocuous water leak behind the washing machine, invisible to the naked eye, created an environment inside the drywall and along the baseboard that was perfect for mold settlement. There was no pooling of water on the floor, so Sarah had no visual clue for remediation, but the airborne spores were circulating throughout the home.

Mold can grow in more places than just basements and bathrooms. This blog will review unexpected places where mold hides in homes throughout Greensboro, how to identify them, what you should do if it is found, and why hire a professional mold remediation company in Greensboro.

Why Is Mold So Common in Greensboro Homes

Greensboro is a prime environment for mold to grow, first because of the humid climate, particularly in the spring and summer, and the abundant moisture found in most areas of the state. 

Whether you live on the coastal plain or further northwest toward the mountains, mold prefers warm temperatures and moisture. Even in winter, mold will grow indoors because it’s insulated and conditions are just right for mold spores to develop. It is most commonly found in:

Commercial HVAC Systems and Ductwork

Commercial heating and air systems regulate temperature. When operating, they also bring in moisture and dust into the home, making it a breeding ground for these microscopic organisms.

Red flags: A musty smell when the system runs, dust buildup near vents, or indoor allergy symptoms worsened in non-natural conditions.

Danger level: You can breathe mold spores that are distributed through the air from your HVAC system and absorbed into your lungs, affecting the overall air quality of the home.

Behind Wallpaper and Pictures on the Wall

Any moisture behind the wallpaper is bad. It can stink, and mold can develop quite rapidly in humid environments, older homes, or in bathrooms, kitchens, or laundry rooms. The risk is higher in areas of walls with wallpaper that are dimly illuminated and may even be hidden behind furniture or wall art.

Red flags: Wallpaper bubbles, peels, or has soft spots.

Under Carpets and Carpet Padding

It usually begins with spills, areas where pets have had accidents, or just tracking in water with shoes and boots from outside. Even if the carpet or carpet pad looks dry, moisture could still be trapped.

Red flags: Stains that keep coming back, odors that seem to get worse, or cold or damp spots under the carpet. Carpet padding can be made of porous material that is not mold-resistant.

Behind Cabinets and Appliances

Appliances like refrigerators, dishwashers, and washing machines can develop small leaks that escalate over time. Often, since appliances are not moved frequently, the leaks go unnoticed until it is too late.

Common mold-prone appliances include:

• Refrigerators (especially under the drip pan)
• Dishwashers
• Washing Machines
• Water Heaters
• Window Sills and Condensation-Prone Areas

Danger level: Older windows or those not properly insulated are more prone to condensation, especially during the winter season. The moisture is often absorbed by the window frame or drywall surrounding the window (either of which can encourage mold growth, especially wood or drywall) before it drips.

Attics and Crawl Spaces

Attics and crawl spaces typically lack ventilation. When warm indoor air moves up into the attic, it cools and creates condensation. Similarly, moisture from the ground is absorbed into the crawl space. Mold-promoting conditions in attics or crawl spaces include:

• Leaky roofs
• Poor insulation
• High outdoor humidity
• Inside Insulation

If your home has endured a roof leak, broken pipes, or flooding, there may be mold growth inside insulation (fiberglass insulation in particular). Once insulation is contaminated, it cannot be cleaned—only replaced.

Underneath Bathroom Tiles

Many believe that grout is waterproof, but it is not. Given enough time, cracked or worn grout can absorb water underneath bathroom tile, and any level of moisture provides sustenance for mold growth.

Red flags: If tiles feel spongy and do not have a smooth surface when stepped on, there is a good chance something is rotting and/or mold is growing.

How to Identify Hidden Mold- Common Signs To Look For

No matter how little or severe the mold damage in your property is, it will likely come with some indicators or signs, including:

• Lingering stale odor
• Prolonged respiratory illnesses
• Bubbling or peeling wallpaper
• Broken areas in the walls or floors
• Water spots or discoloration
• Allergy symptoms in your indoor space

If you experience any of these indicators, it’s time to call a professional mold removal company in Greensboro. 

At All Brothers Restoration, we utilize moisture meters, infrared imaging, and air quality testing to identify hidden mold without unnecessary demolition.

The Dangers of DIY Mold Removal- Why You Shouldn’t Attempt It?

Mold is unsightly, but it can also be toxic to one’s health. Many DIY cleaning methods (such as bleach) do not reach porous materials and can release spores into the air, worsening mold and mildew issues. Dangers of DIY mold remediation include:

• Incomplete removal of mold
• Exposure to harmful mycotoxins
• Cross-contaminating cleaned spaces
• Invalidating insurance claims

Professional remediation is a thorough process that tackles, resolves, and helps prevent any potential return of mold in the future.
