    These guys are real pros. Very competent and friendly. Did a great job cleaning out our dryer vent?

    Cornerstone was prompt and pleasant to work with while cleaning my ducts. They made quick work of fifteen years of dirt, pet hair and miscellaneous objects, they didn't mind my pets and the price was reasonable versus other bids for the same project.

    Solid guys, know their trade, and willing to go a bit above and beyond to get the job done. Could not ask for more.

    Great guys and great service. They came out and gave me an estimate, told me exactly what they were going to do and how they were going to do it. They do a thorough job, not just vacuuming the vents - they get in there and man you'd be amazed what comes out of your duct work! They are professional, courteous and neat. Highly recommend, great price for my one unit house.

    Michael and Jason are courtious, knowledgeable and respectful. They answered all my questions and went above and beyond in teaching me how to prevent dangerous situations. I fully recommend them!

    The vendor was very professional, on time, and explained all work. They even took their shoes off while in our home. We highly recommend Cornerstone IAQ Services for your duct cleaning services!

    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.
