Jose called me back the morning after I left him a voicemail and was able to schedule us for the same weekend. Showed up on time and completed the job within a few hours. Very professional and did not try to sell me anything that I was not shopping for. Excellent pricing and true professional service.

Jose connected with me immediately when I requested a bid. He provided me with different options to meet my budget. And he was incredible affordable compared to the other bids I got.

I called JCJ Insulation after I called two other company's to get a good price, 1st one was $1,250.00 could only come in two weeks. The 2nd one was 1,100.00 and didn't know when he could get to me. I called # 3 JCJ Insulation Jose answered and was vary polite and priced the job at $700.00 and could get to me the next day. He showed up on time and Ready to Work. He did the job cleaned up Everything I expected. I will refer he to anyone both friends and family. ;- )

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
