    Their foreman Marvin did an excellent and high quality job with the drain system and full encapsulation. Affordable and professional. Excellent customer service and remedied/answered all questions I had. Very good value compared to peers in the area. I would recommend to anybody.

    5.0 Nathan B. Powhatan, VA

    My wife and I have used kefficient before when we were having issues with our basement. They did an awesome job for us before, so when we decided to encapsulate our crawl space we knew exactly who to use. They came out and once again were fast, professional, and did an amazing job encapsulating. Our house and air quality feel so much better now. Thank you again! Hopefully we wont need any more services for a while but if we do, we know who to call!

    Response from Company:

    Thank you for choosing Kefficient.

    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.
