5.0 Kelly H. Shelter Island, NY

Derek was great. He inspected both our crawl spaces and told me exactly what was needed. A week later, the space is garbage free, sealed, and de-humidified. The whole house smells better. He also quoted a price and did not exceed that amount. A good experience.

4.0 Bill S. East Marion, NY

Courteous and professional.

4.5 Lorraine B. Sag Harbor, NY

Ben of Mildew Busters is personable, thorough, uses eco-friendly materials, answers all questions, does great work, preps the area and cleans the area and around it nicely. My roof has been in good shape since the last time he cleaned and preserved it a few years ago.

4.0 Suzy F. Quogue, NY

Informative, helpful and prompt.

5.0 Curtisteen W. Shelter Island, NY

5.0 Kevin K. Sag Harbor, NY

Super Friendly and Helpful

5.0 Laura A. East Hampton, NY

They were prompt, neat and efficient. When one follow-up visit was needed to adjust wiring for a new dehumidifier, they returned without delay. Our basement is now free of mildew, drier and fresher than it has ever been.

5.0 Bridgehampton, NY

Showed up promptly and solved my problem!

2.0 Tullia L. Shelter Island, NY

Good at removing mildew on outside of house. No good at cleaning and painting floors after water removal. Price too high.

5.0 Southampton, NY

Very professional and easy to deal with. Great quality of work


Twin Fork Waterproofing, LLC

HomeAdvisor allows Service Professionals to post information about themselves and their business on their profile. HomeAdvisor does not review or verify the information representations set forth in those profiles as they are self-reported by the Service Professional.

HomeAdvisor verifies state-level licensing where applicable - note: some states require local or county level licensing and you should verify whether or not your pro is properly licensed.
To find more licensing information for your state, visit our Licensing Requirements page.

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.
