Smoke odor that keeps returning after cleaning
Why it happens here
Geismar's humidity pulls smoke residue back out of insulation, carpet padding and plywood subfloors. If the source cavity is not treated, the smell comes back every time the air gets heavy, which is most of the year here.
Our approach
We find the source with a thermal imaging camera before we clean anything, then treat the cavity with hydroxyl or thermal fogging. We do not call a job done until the smell stays gone through a humid stretch.
