They are the BEST!!! Cory & David were friendly but still professional. They wasted no time and got right to work. I needed hot water coming from shower and they new exactly what needed to be done. I needed the water heater wrapped...they jumped right on it. They also put in a new bathroom sink faucet for us. I won't use anyone else ever again. I highly recommend this company!!!

David and Cody from John's Waterproofing went straight to work; they quickly found the problem, showed me the problem, discussed what would have to be done to fix the problem, fixed the problem, then thoroughly cleaned up. Very nice people to work with, from the schedulers through the technicians.

Corey and David of John's Waterproofing Company took our project and had a commercial grade gas water heater installed and running in place of our old one the same day they received our call for service. Thank you John's Waterproofing.

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.
