Smoke migration through shared walls and common areas
Why it happens here
Calle Aragon condos share walls, attics, and HVAC chases. Smoke travels through these paths and deposits soot residue in units that never saw flames. The problem is worse in older buildings with unsealed penetrations.
Our approach
We inspect every adjacent unit with thermal imaging cameras before we start. We seal shared penetrations, run air scrubbers in each affected space, and verify odor clearance in every unit, not just the one that burned.
