Insulation removal is important in the event of an infestation. An example would be an attic that has become infested with raccoons. Raccoons leave behind droppings and urine which begin to grow into bacteria and diseases. These diseases can then become airborne and blow throughout the home inside the heating and cooling systems. Soiled insulation is also necessary to remove in order to eliminate unpleasant odors which can attract more pests to the area. When an infestation occurs in an insulated area, insulation removal is crucial to protect the health of the inhabitants in the building.

Insulation which is damaged by water can be a result of storm damage, roof leaks or condensation build up from drafts. Water damaged insulation is dangerous as black mold can begin to grow inside it, which is then distributed throughout the home when the HVAC circulates air, leading to respiratory illnesses. Another crucial reason to remove water damaged insulation is to prevent structural damages. Water can absorb into the surrounding boards and cause mildew and wood rot. Overall, insulation removal protects from pest infestations, diseases, mold, mildew, respiratory illnesses, wood rot and structural deterioration.
