    5.0 Jean T. Smithtown, NY

    Mike and his son, Mikey, just finished remodeling my bathroom. I am very satisfied with their excellent work. Mike loves what he does & it shows. He & Mikey take pride in their work, do a great job and pay attention to detail. They are fairly priced, kind, considerate, understanding, accessible and trustworthy. They go over and above. Mikeâ s wife, Sharrie, is all of the above as well. She was beyond helpful to me in choosing things when I asked for help and gave experienced feedback and information. She did indeed hold my hand the whole way through. She was extremely accessible to me and quickly answered any of my texts, questions or concerns. They are all really good people! It was such a pleasure having them do this job for me!

    When I called Gillespie properties for an estimate on a bathroom leak. And potential bathroom remodel afterwards. He called me back within 10 minutes of leaving a message. And came that evening to give me an estimate and look at the bathroom. I was very impressed on the way he had many creative ideas and how to utilize The space in my old bathroom to make it a new and amazing and bigger and improved bathroom. When Gillespie properties came back with my estimate I was very impressed that it came under from other contractors I had come and look at the same job. I hired Mike right away to do the job. Yes he did the job he came across other issues in my bathroom. He approached me about them in ways that I could repair them and why they needed to be repaired. Overall I am so happy with the job Mike did in my bathroom. I love bringing people into my home and showing them my brand new gorgeous bathroom

    Mike Gillespie is a hard worker and a wonderful person. I had a small job that turned into a big job unexpectedly, and he was supportive and understanding all the way through. He does excellent work and he is a pleasure to have in my home. I can t recommend him enough, especially since I got him from this website. It is nice to have an honest and hard working contractor who I know that I can trust in my house. I can t say enough great things about him!!!

    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.
