Review by in Milwaukee, WI
I contacted the owner, Maretes, requesting a full bathroom remodel on a very short time table. She offered a lot of suggestions, solved several structural problems, and kept me informed of the work to be performed. She did a lot of shopping for the products I needed as I was limited at the time by a medical condition. The entire project was completed in the time frame I needed and turned out better than I anticipated. I now have a beautiful, spa like shower/bathroom that I look forward to enjoying for years to come

Review by in Milwaukee, WI
The owner, Maretes, is absolutely wonderful. She maintained contact with me throughout the entire remodeling process and was very thorough in her explanations of the work that was being done. The price was also very reasonable. There are too may contractors out there that are scammers and they will take your money without completing the project properly, forcing you to pay more money to have it done right. With COR Improvements, I was provided with the peace of mind that the project was going to be completed properly the first time and I am beyond happy with the results!

Project: Hire a Handyman
We had a problematic situation with our custom fence. Not only did COR get the problem fixed but the gate works better than ever!! When everyone else said that they couldnt do anything Maretes and COR made sure that we could have the protected back yard we really wanted :)

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.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
