Frequently Asked Questions

Crawl Space Ninja was founded with the philosophy of offering you a "Worry Free" crawl space, basement or attic. Since 2005, we have helped many homeowners just like you fix the ultimate problem we face in most cases, poor indoor air quality.

Moldy damp basements and crawl spaces wreak havoc on your indoor air quality. Knoxville is usually one of the worst allergy cities in the United States. Poorly sealed duct-work and improperly insulated attics add to the indoor air quality equation.

Since Crawl Space Ninja comes from an indoor air quality background. We want to fix the problem, not just throw a band-aid on it and hope for the best. Our easy to understand package pricing for duct sealing, basement waterproofing, attic insulation and crawl space encapsulation makes it easy for you to decide the best course of action for your family.
