Buying or Selling a Home? Don’t Overlook Mold in Attics and Crawlspaces
When buying or selling a home, most of the attention goes to the spaces we see every day. But when mold becomes an issue during a real estate transaction, the problem is often discovered somewhere much less visible—the attic or crawlspace.
These areas can provide ideal conditions for microbial growth when moisture is present.
In an attic, roof leaks, inadequate ventilation, bathroom exhaust fans venting into the space, or condensation can introduce moisture to roof sheathing and framing.
In a crawlspace, plumbing leaks, groundwater, irrigation, poor drainage, or condensation can leave framing and subflooring exposed to elevated moisture for extended periods.
Because these areas aren't regularly occupied, mold may develop long before anyone realizes there's a problem. It may not be discovered until a home inspection, mold inspection, or other evaluation during the sale.
The good news is that finding mold doesn't necessarily have to derail a real estate transaction. Professional mold remediation can address affected materials, correct the conditions within the work area, and help move the property toward clearance when third-party testing is part of the process.
Whether you're preparing to sell a home or discovered mold while buying one, addressing the issue properly can help prevent a hidden moisture problem from becoming a much bigger obstacle.
