Fire Damage Restoration should begin as soon as it is safe to be in the structure. Since ash is so acidic and easily dispersed in the air when it is disturbed, something as simple as breathing on it can spread it through the air. From there, it can blanket an entire room and make it harder to remove.
When swept up into the air, the building’s climate control system will pick it up and blanket entire rooms, making it much more difficult to get rid of. Because it is acidic, it will eat away at a number of materials if it sits for long, especially glass, metal and drywall.
