|Smoke and soot damage to floor joists after|
a furnace fire in the crawlspace.
The fire occurred in a heating unit in the crawlspace, and other than the damage to the heating unit itself, the only damage to the house was the soot and smoke permeating the wood floor joists.
|The floor joists after dry ice blasting.|
And using dry ice is an ideal cleaning method.
Dry ice removes the physical appearance of smoke quickly and without damaging equipment, wiring, or other materials, and the odor disappears usually within a few days.
Yeah, there are other cleaning methods, but they can create their own problems.
Pressure washing leaves water in the crawlspace, and can wet electrical components, and saturate wood and insulation. Sand blasting leaves behind abrasive grit particles that can damage electrical equipment and contaminates the area with silica dust.
Dry ice blasting cleans the surfaces without the messy residues associated with other cleaning methods.
