If you’re selling or buying a home in New Hampshire, discovering mold in your attic during the home inspection can be concerning—but it should not be a deal-breaker. In this blog, we’ll break down why mold forms in attics, the potential risks it poses, and how to approach remediation, whether you’re negotiating a sale or managing homeownership.
The Importance of Professional Mold Remediation
The first step in addressing mold in your attic is consulting a professional mold remediation company. Depending on the extent of the issue, the cost of removal might need to be negotiated as part of the home sale contract. For expert advice, call PuroClean of Strafford County, New Hampshire’s highly rated mold remediation company, at (603) 664-3727. They’re always happy to help answer questions about your mold situation.

Why Attic Spaces Are Prone to Mold
Attics, when not properly ventilated, can become breeding grounds for mold. Ideally, attic spaces should have fresh air entering through the eave vents, cooling the space, and allowing heat and moisture to escape through the ridge vents.
However, mold problems often arise from improper ventilation, especially when bathroom fans or dryer vents are directed into the attic instead of outside the home. Other issues like insufficient airflow or too much insulation can also contribute to mold growth. Without proper ventilation, heat and moisture accumulate, creating the perfect conditions for mold.
In some cases, homeowners may even unintentionally trap moisture in attic spaces. As one expert puts it:
“When you have cold air traveling through an insulated flexible duct in a hot attic, specifically in parts of the country that are conducive to condensation, moisture problems can occur. In some scenarios, depending on how deeply the duct is buried and which part of the country you’re situated in, blown-in insulation can act as an entrapment for condensation around the flexible duct.” (Why More Insulation is Not Always the Answer, source)
For anyone considering burying insulated flexible ducts, it’s important to remember that your climate zone plays a big role in whether this is a safe solution or could lead to moisture issues.
Impact of Attic Mold on Your Home
While attic mold may have difficulty spreading to the lower parts of your home due to the Stack Effect (where warm air rises), it can still cause significant damage. Over time, untreated mold compromises building materials like drywall, wood beams, and insulation. This deterioration can lead to bigger problems, such as roof leaks and even structural collapse if not addressed.
What to Expect from the Mold Treatment Process
Here’s a quick breakdown of the mold remediation process:
- HEPA Vacuuming: Removes excess mold spores from the affected areas.
- Surface Treatment and Cleaning: Removes spores and kills any remaining mold roots.
- Air Scrubbing: Air scrubbers are used to filter mold spores from the air during and after the cleaning process.
