What we do here

Northeast Florida — Jacksonville, the Beaches, St. Augustine and the First Coast — has its own IAQ profile: more pronounced winter swings, more crawlspace and pier-and-beam construction, and a higher rate of mid-century housing stock with unique moisture and envelope challenges.

Local conditions

What we see in Northeast Florida

Crawlspaces and pier-and-beam

Unlike the rest of Florida, Jacksonville has a meaningful share of crawlspace and pier-and-beam construction. Untreated crawlspaces are humidity engines — we routinely measure 80+% RH below floors that occupants notice as cupping hardwood, cold floors and persistent musty odors.

Winter temperature swings

First Coast winters dip into the 30s and 40s overnight. Buildings sized only for cooling load condense on interior surfaces during those swings, leading to localized mold growth that does not appear until spring.

Mid-century housing stock

Riverside, Avondale, San Marco and other older Jacksonville neighborhoods present a mix of chronic-moisture failures typical of pre-1980 construction — settled framing, envelope penetrations, updated HVAC layered over original ductwork. Diagnostic work on this stock is a routine part of our Northeast Florida workload.
