Q: Why should I have my crawl space and attic cleaned?
A: Even if you don’t use your crawl space or attic for storage or other uses, having a dirty or contaminated attic or crawl space can still cause problems in your home. That’s because contaminated air can flow into your home, aggravating allergies or sensitivities, negatively impacting your energy bill, and creating poor air quality. Local attic and crawl space cleaning companies are able to remove dirt, debris, rubbish, rodent droppings, mold, and other contaminants and repair or install vapor barriers and insulation.

Q: How often should I have my crawl space and attic cleaned?
A: Many experts recommend having your home’s attic and crawl space cleaned and inspected annually. This includes inspecting the insulation, looking for the presence of pests or rodents, damage to the roof or attic/crawl space structure, and clearing away debris and rodent/pest waste products. Many local crawl space inspectors and attic cleaning services will provide annual inspections and cleaning for reasonable rates that offer peace of mind and a cleaner home.
Q: What is attic decontamination or crawl space decontamination?
A: When pests including rodents like mice, rats, squirrels and raccoons take up residence in your attic or crawl space, they leave behind waste. This can spread disease, allergens, and toxic particles, and can signal to other rodents that the space is livable. Attic decontamination and crawl space decontamination services remove the visible waste and debris, and the best ones will use a sterilization solution to eliminate bacteria and diseases.
Q: Can I stay in my home while the attic cleaning or crawl space cleaning is underway?
A: In most cases homeowners can stay in their homes during crawl space and attic cleaning. Most cleaning and decontamination services only take a few hours, and even repairs and replacement of damaged or faulty materials can be done without disrupting the household. Only in rare cases will you need to make other living arrangements during the services. Talk with your attic cleaning company and crawl space cleaning service to ensure that you can be in your home during the work.
Q: Can local attic and crawl space cleaning services rodent-proof my home?
A: Many good crawl space and attic cleaning companies also offer rodentproofing and rodent prevention. This often includes an inspection to look for areas of access, chewing or nesting damage to the structure, access holes, cracks, structural damage, or other areas where pests such as rodents and insects are gaining access or living. Then the company will create and implement a plan including blocking holes and cracks, repairing damage or replacing damaged items, and otherwise rodentproofing and pestproofing the space. Talk with your local attic cleaning service or crawl space decontamination company to learn what they can offer in terms of preventing future rodent and pest access.
Q: What is attic insulation removal?
A: Attic insulation ages and can become brittle and disintegrate, creating a mess in your attic and even pose a health risk if insulation particles are transferred around your home via your ventilation system. The same goes for attic insulation removal. If you or your attic cleaning company don’t remove old attic insulation in the right way, it can create an even bigger mess and a health hazard. Removal must be done correctly, as must bagging and disposal.
