5.0 Jose C. San Jose, CA

5.0 Sarah B. San Jose, CA

So appreciated his focus on making the place more energy efficient! My insulation was so old and no longer served its purpose. My heater was running constantly and I could not keep any cool air in during the summer. Fernando was very professional. He helped me understand what my options were and gave solid recommendations throughout the process. I am so happy with his work and will absolutely keep his information handy in case I need work done in the future. I would highly recommend him!

5.0 Dennis H. Mountain View, CA

A pleasure to work with! Showed up on time, did explain well what they are planning to do, and did the work.

5.0 Charlene N. San Jose, CA

Fernando the quality control manger of Tempest Insulation was very professional. He made himself adaptable to our needs with our contactor. He worked very will with our schedule to complete the job. Our home is so much cooler in all rooms as a results of the foam spray . The cost was very reasonable to fit our budget . Thank you Fernando for all your help in caring for our home.

5.0 Himanshu M. San Bruno, CA

Amazing service! Not only did they do an awesome job at a competitive price, but when we called a few weeks later for an issue, they were quick to respond and came over to assess within a couple of hours. Would hire again for sure!

5.0 Tanvir A. Belmont, CA

Fernando is great. He was there through the work to address any concern.

5.0 Gary W. Union City, CA

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

5.0 Alex V. Walnut Creek, CA

All good but may somewhat improve on customer communication and post work area cleanup.

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.
