5.0 Wally C. Luther, OK

Good work, price and quality of materials.

5.0 Wesley M. Yukon, OK

I donâ t know anything about insulation, and I havenâ t had enough weather yet to tell you if it made a difference. But they seem like good honest people that know what theyâ re talking about, so, and they certainly did put in a bunch more insulation. So I think itâ s probably gonna be great. I liked working with them, seem like great people, they were on top of things, respectful of our property, and they seemed to try and give me good advice that was buying exactly what we needed as opposed to the most expensive thing they can sell me. Iâ d recommend them, they seem great. I donâ t have the expertise to actually evaluate their results. Just know that they were great while they were at our house and seemed very knowledgeable when they sold me stuff and thatâ s all I know.

5.0 Tina shepherd S. Oklahoma City, OK

I was very pleased from the beginning to the end. The lady that handles the calls was very knowledgeable and helpful. She had me sold even before the guy gave me an estimate. I had insulation but in my attic and outside walls. One outside wall had fiberglass in it. The owner told me about it and deducted it from my It's good when you find honest people.

Response from Company:

Thank you so much for your time and wonderful words of praise. You were a joy to work with and wish all customers were so nice. Thank you again.

5.0 Kathleen T. Guthrie, OK

I was taken aback by Harper's excellent communication! I understand that environmental factors play heavily on the difficulty of this project, but at every turn, Harper's were willing to work with us to meet our project needs! Don and Stacy worked very hard to ensure that our insulation was installed properly and went above and beyond my expectations. I recommend them to anyone with an insulation project.

Response from Company:

Thank you so much for taking your time to write such nice & kind words. We appreciate you and your business - you were so nice to work with as well. Thank you again.

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.
