Not a firm that takes advantage of your ignorance and creates fear... doesn't sell what you don't need!

Tempest Insulation, Inc. is definitely NOT a 5 Star. It is more like a TEN (10) Star! Fernando Romero and his crew were very timely, professional, clean and finished the project at my house in less than a day. They exceeded my expectations. GREAT JOB! GREAT PRICES! I would very highly recommend Tempest Insulation, Inc. Thank you Fernando Romero and Crew.

Tempest insulation with Fernando are going to be my go to team for any future insulation needs. I used tempest for a R44 blown in insulation. Fernando was on time for the estimate, sent me a follow up with responses to all my questions and began the work at 8 am on the dot! He and his crew were timely, professional, clean and were in and out of my place in less than a day and cleaned up everything after themselves. I would highly recommend them!

The Tempest Insulation's crew that worked in my project managed by Fernando arrived right on time and worked diligently throughout the day until finished. They had all the necessary tools, and materials. When they finished, they cleaned up everything and showed me the finished project and photos. I would highly recommend this crew. 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.

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.
