I waited a month for service.the insulation did nothing to prevent sound from going through the wall.

5.0 Tom S. Bangor, ME

Jason spent an hour looking over my house with me, drilling several holes to see the existing situation (and neatly covering them after): He found my walls had been filled probably several decades ago with fiberglass blown-in insulation. It had settled and wasn't super tight, but his judgement was that it did 3/4 or more of the insulating that could be done and further insulating in walls wasn't necessary, effective, or cost efficient. Then he showed me in basement where I myself could easily foam-seal sill to lumber (ends of floor beams, resting on the sill, where outside air was getting in) using a home depot product, and several other such thorough useful suggestions. From this unusual angle, I very strongly recommend Northern Insulation as a very unusually reliable company to work with.

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

HomeAdvisor verifies state-level licensing where applicable - note: some states require local or county level licensing and you should verify whether or not your pro is properly licensed.

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.
