Many homeowners are attracted to the lower upfront cost of blown-in cellulose insulation, but those early savings can lead to costly issues over time.

From moisture absorption and mold growth to settling and potential fire risks, understanding the dangers of blown-in insulation is essential—especially for homeowners in Albuquerque, NM where climate conditions can impact performance.
“If I wouldn’t put cellulose insulation in my home, I certainly won’t put it in yours.“
