Mold growth in basement and crawlspace ducts
Why it happens here
Humidity off the Housatonic River keeps ground-level duct surfaces damp for much of the year. Flexible duct insulation traps that moisture against the inner liner. Once mold starts, it spreads through the run.
Our approach
We inspect with a duct camera inspection system, remove affected sections, and treat the rest with antimicrobial spray. A sanitizing fogger reaches surfaces a brush cannot. We also recommend a dehumidifier for crawlspaces that stay damp.
