Mold growth in air ducts from coastal humidity
Why it happens here
Homes within a few blocks of Bayview Beach and Milford Harbor stay damp longer through the year. Duct insulation absorbs that moisture, and mold establishes on the inner duct surface within a single season. It is the most common problem on our Bayview route.
Our approach
We locate the growth with a duct camera inspection system, remove it physically with a rotary brush system and HEPA vacuum, then treat the duct with antimicrobial spray. We also check the basement or crawlspace for the moisture source, because treating the duct without fixing the source means it returns.
