This company was one of the first to respond after putting out my request for work on HomeAdvisor. Wil is a very personable business man, his client relations staff is wonderful and they were able to begin work on the project in a reasonable amount of time from first point of contact. I loved the fact that Wilâ s company took on my smaller kitchen project, as most companies had a threshold amount of $4k and didnâ t want to be bothered. Wil has excellent contractors and walked through project with me upon completion. Heâ s got got my future business!

His professionalism in detail in the work was amazing. We are always a little inhibited and pulling people into the house to do a job because the quality is not always up to par. This gentleman came back multiple times to make sure everything was exactly the way we needed it. He was friendly and very easy to work with.

Response from Company:

Thanks for the review! I very much appreciated the opportunity to have worked on your project. Wilhelm

I was extremely pleased with Wilhelm. Great personality, hard worker, knowledgeable and completed my project in the most efficient manner. I would not hesitate to hire him again. In fact, we are already discussing another project.....

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.
