5.0 Dustin K. Seattle, WA

Very professional, responsive, and did great work. Highly recommend.

5.0 Evans C. Seattle, WA

Cube Insulation fully insulated our house from the crawl spaces to the attic, also the garage walls and ceiling. They were very professional and informative of the steps in the process and a pleasure to work with. They removed the old insulation, cleaned the site and rolled, sprayed and installed reflective insulation and vapor barriers where applicable. They also pointed out areas that needed attention even if it was not their job description and made some minor fixes and repairs because they saw that it could be better, If I ever need anything done around my home Cube Insulation will be my first call.

5.0 Daniel C. Seattle, WA

Very communicative company. Their work was very good and the value for the money felt good as well.

5.0 Don C. Conneaut, OH

Outstanding! The workers are consummate professionals. All of the old insulation was removed along with replacing all of our heat ducts. The attic was inspected for mold and each duct was sealed and wrapped before the new insulation was blown in. From employee to owner, this was a pro job. We are very pleased with InsulationCo/ Cube Insulation Thank you!

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
