Quick and reasonably priced. A little difficult to pay since it was electronic but other than that I'm pleased with the results.

Guardian Insulation is a class act! Jesse was very professional and sincere when listening to what I wanted to accomplish. He helped me acquire rebates and financing and stood well within my budget to complete the project. Mark was excellent with the install and took the time to answer any questions I had. Clean and efficient so much so that after the project was completed you couldn't even tell they had been there. Glad to see that there are still honest contractors out there! I would gladly recommend this company and will be doing business with them again soon.

They were responsive, quick, and best priced of all the companies I contacted. Although they didn't have the equipment required to complete this particular job, they subcontracted with another company, kept the price the same, and did a good job. I would definitely use them again.

Brian, the salesman, was knowledgeable, efficient, and seemed to be experienced. The price of the installation was reasonable. The technician Eric arrived on time, set up equipment with care, and worked fast. He was courteous and very pleasant. The clean up was super. I am considering hiring Guardian for a future project.

Jesse Cota, the salesman, was excellent and so professional. He knows his product well. He helped me to realize what I needed done and what I didn't need. I really appreciated him helping me with my rebate as well. Mark, the tech, was punctual. He was very thorough on his explanations of what he was doing. He even fixed little things that weren't on the list to be done at not charge. I really appreciated that. Mark is such a hard worker and very meticulous of his work. That is No. 1 in my book. I would definitely recommend "Guardian Insulation" to my family and friends! Thank you for a great job!!

The old insulation removable was OK, but they did not have the equipment necessary to do the work and was rather rough with the area. They damaged several sprinkler heads which I fixed. The installation of the new was a bit messy. I requested that the openings through the ceiling be closed so the dust from blown in insulation would not come into the living area (the old did come in badly) and it was a struggle to accomplish. I kept telling them about problem areas. After my wife and I cleaned up the excess dust and waited for any leaks of dust, it seems to be OK now.

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.
