This was a very professional business with good communication and great workers . The manager Dan made a great observation that two other companies did not mention which saved a lot of work and tearing up of my backyard. The price was very fair. A great team.

Dan and his team were outstanding. They accomplished everything we discussed in just 2 days! AMAZING!! And my basement is as dry as a bone now. I could not be happier and I would recommend Conerstone Waterproofing in a heartbeat.Dan was very professional and took the time to explain the entire process and answered all of my questions as well. And after the job was done his crew took the time to clean up leaving everything in good order, awesome.

Review by in Brick, NJ
I just had the work done today, so it’s too soon to tell how the waterproofing system works- but I didn’t want to wait to write a review because my experience with Cornerstone was so positive. I spoke with several companies to get quotes to have a drainage system installed, and Cornerstone stood out from the rest. Dan is extremely honest and knowledgeable, and encouraged me to take the time to speak to as many companies that I wanted to to make an informed decision (and I had two different companies try to pressure me into signing a contract on the same day). He also took extra time to answer all of my questions, and I assure you that I asked him a lot! The crew that showed up today to do the work were all very nice, and did an outstanding job. They also worked very neatly, and cleaned up afterwords to the point that you can’t tell there was major work done in my basement today. I wouldn’t hesitate to recommend this company- from start to finish, they made what could have been an extremely stressful project completely seamless and stress-free.

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. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
