Yes it is cheaper but not better. Hiring an attic cleanup company may look costly but you will reap many benefits you can’t find if you do the cleanup yourself. Apart from dust and debris, the attic might be contaminated with bacteria and other pathogens that could make you sick. Professionals come ready with the right gear to protect themselves from such contamination and the right equipment to clean everything without contaminating the rest of the house. Professionals also have the right disposal measures for old and contaminated insulation and therefore their work is safer for everyone concerned.
