A monthly charge, if it snows or not, Already made two monthly payments did not get the first snowfall until the Second week of January. They epically failed never cleaned. The approaches to the doorways called customer service said theyâ d send somebody right back out never showed call them again they said oh theyâ ve been there already. no, they have not Iâ m looking at the snow piled up in front of the door they where never here it makes me wonder why was I paying for the services if theyâ re not gonna clean the approach to the house and then they push the snow up in front of my stairway to made matters worse would not recommend them for anybody. Would like to see the owner of the company would appreciated the job done by their employees. Do they do that at their place!! Why would you Pay for Snow Removel, and not have it cleaned to the approaches to the house. Terrible service.

5.0 Kawana M. Milwaukee, WI

Demark's responded right to my request through Home Advisors with a quote. Lexi provided thorough information and was able to schedule me within a week of talking. The price was very reasonable for my garage and 2-story house (under $200). I paid for that for the house alone. I will continue to use and recommend Demark's to others. Thank you Demark's for making a good 1st impression.

5.0 Louis M. Dousman, WI

The team that came out were friendly, business like and were working all the time. The windows were all done by hand, not spraying a solution on them and letting them to drip dry. This experience was a welcome pleasant experience. I will speak well for them and use them again.

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.
