Attics are often neglected, but they should be cleaned regularly. Dust, mold and allergens tend to collect in the space under the rafters. Often, rodents such as mice, rats and even raccoons make nests and leave droppings in these warm, unnoticed areas. Rodent feces and urine can contaminate insulation and cause moldy areas in the wood; left untreated, they can lead to unhealthy air conditions in the home. Dirty attics can also raise a home's heating and cooling bills because old, damaged insulation becomes less efficient at regulating the air temperature. The cost to clean an attic depends on how large the space is and whether there’s a rodent infestation.
Average attic cleaning and decontamination costs
The typical attic cleanup costs about $3,100, including decontamination services. Having both insulation and rodent feces removed costs about $1.50 per square foot, while installing new installation costs $1 per square foot. Deodorizing and disinfecting the attic usually costs about $200.
For example, Attic Stars in Humble, Texas, starts by removing dust from the attic space, then cleans up any animal droppings and decontaminates the attic. If necessary, they can remove old insulation and install new. Attic Crew in Palo Alto, California, offers rodent control and proofing as well as attic cleanup services, and can also remove and replace insulation.
Attic rodent waste removal
Rodent droppings are considered biowaste and can be dangerous to remove. Professionals use personal safety equipment, including biohazard suits and respirators, to avoid disease. Compared with the cost of acquiring this equipment, the average cost of $200 for a professional to handle the job is well worth it.
Attic junk removal
If your attic is also a storage space for old items and junk, you can hire a junk removal specialist to remove those items before cleaning. The average cost of junk removal is $169 nationally, but varies depending on the type of junk, the accessibility of the attic and other factors.
