Programs that clean and restore property that has been the scene of a violent crime, accident or unattended death, or used as a methamphetamine lab. Crime scene and trauma cleaning services have specialized training and equipment to deal with homes and businesses that have been contaminated by blood, body fluids and other biohazards, fingerprint powder and other evidence-gathering chemicals, tear gas and pepper spray residues, fire extinguisher residue and other conditions that render a space unusable.

Programs that clean and restore living spaces that have become uninhabitable as a result of gross neglect or hoarding of material goods or pets to the extent that the need to acquire things interferes with daily routines, causes a safety or fire hazard or creates an unsanitary environment. Most commonly hoarded items are newspapers, magazines, food containers, cups and sometimes animals; but mold, human and animal waste, old food, rodent droppings and insect infestations are often also found. Cleaning services take care of bulk debris removal, structural cleaning, disinfection and cleaning of all remaining contents; and are trained to look for and preserve photographs, cash, stock certificates, life insurance policies, collectibles and other items of value.

Programs that provide for the safe removal of mold spores and mold or mildew that is growing on surfaces in homes, business establishments, public buildings and other structures.

A pattern of behavior that is characterized by the excessive collection of possessions (often items of little value to others such as old newspapers, containers and clothing that may someday be "useful") coupled with the inability to discard and/or properly organize them creating a messy, sometimes unsanitary environment that, in extreme cases, no longer functions as a viable living space. When these behaviors are combined with severe self-neglect and hostility to the outside world, Diogenes syndrome (also known as senile squalor syndrome) may be the proper diagnosis.

The parents, children, spouses, partners, friends or other relatives or significant others of people with a compulsion to acquire possessions which clutter the living space, whose own patterns of personal, social and familial coping have been significantly affected by concern about the individual and his or her compulsions. When these behaviors are combined with severe self-neglect and hostility to the outside world, Diogenes syndrome (also known as senile squalor syndrome) may be the proper diagnosis.
