5.0 Philip W. Farmingville, NY

I was contacted by Danielle who gave me an estimate over the phone. She was very pleasant and explained everything in detail. John and Lucci came over to do the installation. They were super friendly and completed the job in 2 1/2 hours. It could not have gone more smoothly than it did. I would definitely highly recommend them.

5.0 Tom M. Northport, NY

John and his son did a great job! Showed up on time for both the estimate and installation and did our small job for a fair price. I have already recommended him to my neighbor and I would definitely hire him again

5.0 Lawrence S. Farmingdale, NY

Quality work , the new gutters and down spouts look great and do not leak. They also fixed damage LEAF FILTER did installing their gutter junk. The people did great work, and cleaned up very nicely. I recommend Water Management above the rest.

5.0 Joe I. Saint James, NY

John and his assistant were both incredibly kind, honest and perfectionist! They installed new gutters and solved our problem with drainage and flooding! They went out of their way to not only complete the job in a timely fashion but were true professionals! We highly recommend them!!

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.
