    Great customer service! I was able to get a same day appointment and kohmar was very professional and explained everything that would be done. The total cleaning process only took about 30 mins. I plan on using them in the future.

    5.0 Emad J. Moseley, VA

    Update: After the initial hiccup in the service, I received a call from co-owner of the business who was apologetic and sent the crew to fix the dryer vent issue the same day. The crew was very friendly and clean the dryer vent very thoroughly. The job was quite difficult since the outside opening of the duct was quite up high, but they were able to clean it thoroughly this time. They refunded the initial service charges. Excelled customer service and i would highly recommend them. Not often do you see such good customer service.

    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.
