Review by in Newburgh, NY
I am so glad I went with Gregg and his team! They were amazing. He came did a full quote explained everything in lamen terms, showed up on our agreed upon date and did everything and then some in one day. I am so grateful and satisfied with the job. Even after the work was done and I had questions he sent someone out to check it out and make sure everything was ok! Gregg and his team are invited to all of our family bbqs! Thank you so much Gregg!

Review by in Goshen, NY
I have to tell you that this contractor was extremely professional. I have hire may of contractors in the past and this gentleman and his crew exceeded ALL expectations. My basement had been flooding for years and we finally decided to hire someone. Let me tell you, they came in here and in ONE DAY they completed the job. He came to my house with a CREW, not with just a helper, a CREW and they bang this job out. Price was reasonable too. Before they left, they cleaned every single area that they may have gone through left my basement and the outside where they were dumping all the debris CLEAN.... They even washed it down my driveway and left everything immaculate. I’m telling you from experience there are very few contractors that will leave the job site clean. I told him I would wait to write a review because I wanted to be sure that is life time guarantee that my basement would never flood again actually worked. WELL so far so good, we have had multiple rain storms and my basement is bone dry. Even the slightest of rain would come pouring through down into my basement. And now NOTHING!! We now can actually start using our basement again as our family room. Thank you so much Waterproofing Corp. and Crew, you guys are amazing and I’m truly glad we chose you. God bless.

Review by in Poughkeepsie, NY
Gregg and his team were on time, extremely professional, neat, all of the above! The quality of the job done is 100% effective. I had Hydro-static pressure and water coming in through my basement floors every time it rained, Gregg analyzed everything in a matter of seconds, gave me an absolute fair price, best in the industry, gave me a commercial quality job at my residence and even took care of relative issues that I had in my basement concerning the garage area, the level of the floor, and an old sump pump. I would absolutely recommend Gregg Segnit and Contractor's Waterproofing, Corp. for anyone's water proofing needs. He has been in this profession for years and knows what he is doing. He stuck by his word to everything he said, and actually left my basement in better shape than it was before, outside of waterproofing. Since him and his team completed the job I have not seen one ounce of water in the basement. Not one drop. Before then, every time it rained outside I would get water coming into my basement from all angles, the wall and floor. He installed in my opinion the perfect interior drain system for my home, at a reasonable price, and with a lifetime guarantee, I cannot be happier as a homeowner. I will never go to anyone else for my waterproofing needs. Thanks again Gregg and team

Gregg was awesome and really knows his stuff. I want to finish my basement to add an apartment so a good drainage system was crucial and Gregg and his guys did a great job, it was very clean and took only two days. They went above and beyond. Highly recommend them!!

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)
