    5.0 Brendan D. Columbia, MD

    Would score them 120% for quality. Of work done in timely fashion

    5.0 William C. Cumberland, MD

    Extremely professional. Great work and finished job in the timeframe quoted. Would recommend.

    5.0 Stephen S. Hagerstown, MD

    Steven and his team were very professional, didn't use any high pressure sales tactics (like some of my other estimates tried), showed up on time, and completed the work in a very timely fashion. Given the opportunity, I would most definitely hire them again.

    5.0 Tammi J. Hagerstown, MD

    The job was completed ahead of schedule. The crew performing the work were very professional and hard working. I would definitely recommend this company

    5.0 Kathleen O. Gettysburg, PA

    They were professional and timely, but they were also my highest bid. I hired them for their guarantees on the work and their sales rep was very good in that I never felt pushed, he showed me exactly what they would be doing and spoke to me as an intelligent human, not condescending. The guys doing the installation were courteous and workers, they didn't dawdle about or goof off, and it was hard work ripping out my basement floor and digging through all the underlying rock to make their trench. And they did it all in 3 and half days.

    5.0 Dorothy B. Taneytown, MD

    The workers completed the job as explained by S. Younkers and we are pleased with the completed project. I would recommend this company.

    4.5 David P. Brunswick, MD

    Very courteous.

    5.0 Andrew B. Frederick, MD

    Mr. Younger identified my basement leak problem quickly. He communicated in a courteous manner. His crew was on time and completed the work as described. Personally I think the charge was excessive, but I really needed this problem fixed, and AA Waterproofing performed as expected. (Hopefully .... I 'll know for sure after the next huge extended rain storm !)

    5.0 Ann S. Knoxville, MD

    They scheduled the job and showed up on time, completed the work in one day and cleaned up well. Job well done.

    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.
