    Company did power washing job 3 years ago, I was completely happy with their job, I requested the job this year 4/8/26. The company's reputation is solid. Shawn's work is thorough, meticulous, and reasonably priced. I plan to continue to stick with this company for future work on my house if and when needed.

    Shawn was quick to respond to my request for a quote to power wash my entire house and sidewalks. When he came to do the quote he carefully and simply explained the work he would be doing and how he would be doing it even going so far as to explain the science of power washing to me. After agreeing to the quoted work he began his work taking only a few hours. In the end the result was exactly as he promised and everything was much, much whiter and cleaner. I am very happy with the work done and I would recommend him to anyone else.

    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.
