    I found the home energy audit to be well worth the investment.

    They were the only company that would complete the project start to finish, including paint. Very professional, kept us informed along the way of what was going on and did a stellar job of cleaning up as they went along to minimize dust.

    I have antenna TV and I think when they are in the Attic they moved my wire from my antenna. I have lost several channels on my TV. I do not have cable so I depend on these channels. Otherwise they did a great job. Thank you

    There was a little confusion in scheduling because one of the workers got sick. However we quickly rescheduled, and a crew was freed up and they sent them by. Great work, very pleased.

    They took out my asbestos on Friday and made us spend the weekend without a/c during a hot spell. When I questioned the decision not to do the asbestos on Monday morning they said it could not get done on time given what else they had to do. But the asbestos got done in about an hour and on Monday they did not work a full day. So it could have been done. The work they did (Radiant Barrier, Attic Exhaust fan, Redo venting system - $6100) helped reduce the heat on the second floor, but the improvement was less than expected. It is better, but not $6100 better. I expected better results. Then one of their workers had a power steering oil leak and it stained my relatively new driveway. I tried to get it off but I failed. They sent the guys back to try but they failed too. It is a series of 3 or 4-inch stains. Not a deadly thing, but still not what you expect. On the positive side: They did do everything on schedule, without incident, and they did keep the place clean. The workers were congenial and not disruptive. Their work has improved things. If you are considering using them, I would exercise more control of what and how they work to get the best result.

    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.
