After a fire, one of the most challenging parts of the cleanup is removing the smell of smoke. Smoke odor can settle deep inside walls, insulation, furniture, flooring, and even structural framing. It lingers long after the flames are out, and homeowners often search for the best way to eliminate it. Two common methods you may come across are thermal fogging and ozone treatment. While both are widely known, they work very differently and come with very different safety requirements. At Lightning Restoration, we use methods that protect homeowners, preserve property safety, and follow approved standards. This guide explains how thermal fogging and ozone treatment work, how they compare, and which option is genuinely safe for your home.
