First time I used there services (window cleaning). They did a great job and were very polite and efficient. I will certainly be using them again in the future for some of the other many services they perform/offer. Thank you again for a great job. I can see clearly again!

Many of our plants suffered greatly: blossoms dried up, leaves turned color snd fell off. They said would pre-wash first and then spray a neutralizer afterward. Am unsure if that was done because so many plants suffered. We didnâ t wish to follow him around but maybe should have to be sure the plant spraying was done. Wonderful worker who was friendly and knowledgeable about the process. Redid some areas that were showing spots.

From first contact to last, this company was a pleasure. The friendly and efficient crew of Kaelan, Anthony, James and Brandon cleaned our windows expertly and carefully on an old 1910 house, even the third floor windows on ladders. Wonderful job.

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

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.
