I had Carlos come do my shed/shop. The job looked horrible. When I asked him to fix it he said it would cost more money. Then he went and brought a kid over to shave the wall and he was there for 5 hours by himself. The kid did not know what he was doing and said this was the first time he had ever done anything like this. He did a Chop job. When Carlos returned late afternoon I told him I still was not happy, After some words with Carlos, he shave the walls down so I can cover up the poor job, However my ceiling look bad I feel like I am in a cave. I asked him to smooth it out and he said it would take away too much insulation. What ever product he used still does not cool my shed down much. I would not hire him back and would not suggest you let him insulate a dog house. I would post pictures but I do not see anywhere to upload so you could see the horrible work.

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)
