Do not let the whole family owned business since 1959; fool you. I had to have this company come back 3 times to do a job that should have been done correctly in the first place. They never covered all the open rodent accesses, so they had to call another 3rd party vendor. They left 25% of the vermiculite and had to come back for that. After fixing that problem, they never reinstalled the insulation that was moved in the back area of my attic. I contacted them back and the continuous response was "I will call you back and it turns out that Cynthia (Ofc Mgr) stated that the owner does not know what else he can do for me. WTF!!! They got paid for their horrendous service and now they are wiping their hands of any further obligations to make their work right. The people that gave good reviews may have not went into their attic to check out the work, like myself. IT IS HIGHLY RECOMMENDED THAT YOU FIND ANOTHER INSULATION COMPANY. DO NOT USE THIS COMPANY IF YOU WANT QUALITY WORK.

Response from Company:

This is Steve, the owner of Everguard Insulation. Normally I maintain a professional composure when responding to reviews but with this particular situation (my first time ever) I'm compelled to simply respond by explaining that this customer is simply all 31 flavors of crazy! We bent over backwards to make her happy, performed significant additional work that we did not charge her for, repeatedly returned to the jobsite to find no issues and had to entertain countless hostile messages and conversations along with wild accusations that she would later retract or we would demonstrate were unrelated to our work. She was verbally abusive to my crew and office staff and at one point threw a pair of scissors at one of my guys. Simply irrational and unreasonable; could NOT make happy no matter what! Please consider our many other great reviews and do notice all her other reviews: she uses Yelp as a weapon and leverages companies to do additional work under threat of reprisal.

5.0 Patrick S. Santa Ana, CA

Very straightforward and easy to work with. Understood what I was looking for and gave me a direct quote upfront. There were no attempts to upsell their products and services like other companies I received quotes from. Just honest business, which I appreciate.

5.0 Sandy G. Norwalk, CA

Amazing experience!! Upfront in the cost of the project and explained everything about how they go about the project. Price was very good, and work was done quickly and looked perfect. Plus they made sure I was happy with the end result. I would highly recommend this company to any and everyone.

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.
