Review by in Milpitas, CA
Prompt service and good work. The drilled holes in the stucco and the patch work was excellent, can't easily see the patch, if at all in some cases. The only negative is that since they finished after dark, the cleanup wasn't as good as I would have liked.
Response by Bay Valley Insulation, Inc.: If anything in a cleanup is missed, just let us know and we'll come back and take care of it.

Friendly, upbeat and the bottom line it really works! Tony and Henry are amazing! They know what they are doing. They would point out things I would have no idea about. Great value! The warmth is so much appreciated!

We did attic and wall insulation with these guys. Estimate was very reasonable. They came on-time and did a good job for the walls. But they were very late in finishing the job for attic(completed by 9:30pm). Not really sure how well they have done on the attic (due to the attic, i have reduced half a star).

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.
