    5.0 Arthur C. Smithtown, NY

    Bill Mason of Mason Carpentry, tore down our wooden deck and replaced it with Trek flooring. He and his crew were extremely neat, polite and very hard working men and finished the job in one day at a very reasonable price. I highly recommend him and will definitely hire him again when needed. Artie- smithtown

    5.0 Maureen A. Nesconset, NY

    They were clean and took all the material that was replaced

    5.0 Larry L. Centereach, NY

    Very professional, courteous and reliable. I will definitely have him back for another job.

    5.0 Steve D. Lake Grove, NY

    I recently moved to a new home and needed help installing a mailbox. I reached out to Bill from Mason Carpentry and he was quick to respond and willing to assist. He came to my home only a couple of days later to install it. Bill was great, incredibly friendly and professional. As a new homeowner, I need all the help I can get and I will absolutely be using Bill again for other projects. I would definitely recommend Bill!

    5.0 Alexa M. Smithtown, NY

    Bill contacted me immediately and scheduled an appointment to trim kitchen cabinetry for a refrigerator delivery the next day. He and Travis were professional and their services were reasonably priced. I will definitely call upon Mason Carpentry for my handyman needs.

    5.0 Kathy P. Smithtown, NY

    Bill did an excellent job installing closet rods and shelving in my master bedroom walk-in closet. He communicated with me about when he would be at my house and was able to do the job quickly. His pricing was reasonable and I am very happy with the finished product.

    5.0 Sharon M. Stony Brook, NY

    My husband and I were very pleased with the work. Our shed was repaired, the floor tiles were installed along with new light fixtures. Bill was on time and was very reliable. We're going to use him for more projects!

    5.0 Mark W. Kings Park, NY

    They showed up on time, worked diligently until the job was done. Very Professional.

    5.0 Janet V. Kings Park, NY

    I feel like I hit the jackpot. I called Mason Carpentry On Thursday to replace my bathroom exhaust fan and to replace my bedroom ceiling fan. He was here early the next morning to give me an estimate. Did the job Monday. He and his helper are really nice guys. He price was very reasonable. And he did an amazing job. I am so happy to have found him and I won’t hesitate to use him again. If I could give him 10 stars I would.

    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.
