Great service, professional, knowledgeable, affordable and fast and tidy. A crew came out on a holiday and took care of my issue post haste. Would definitely hire again.

Water / dampness in basement - 1st appt with AJ was a walk thru and he shared recommendations on options he could or i can try to remediate. AJ checked in with us a week later to see how we made out. Our attempts minimally helped, but did not fix. AJ was aware of time constraints, team came in, hustled and completed in one day. super impressed with quality of work, professionalism and cleanup.

AJ didn't try to oversell me on unnecessary work proposed by other contractors. He removed a truckload of stuff from the basement room with the water problem at no extra cost. When they finished installing the interior & exterior drains and cleaned the floor the room was cleaner than when they started. After one rain there was some water on the floor but it dried before AJ could come out. We haven't had a heavy rainfall since to really test the system, but I'll increase the rating to 5 stars when it's had more of a test.

Review by in Downingtown, PA
AJ provided me with a thorough and very professional assessment of our basement water issues and I chose him over several other contractors based on his obvious knowledge, no-nonsense straight talk and strong references. He and his crew did a top notch job installing the interior perimeter drain system and two sump pumps in our large basement, as well as exterior regrading and foundation waterproofing at a very reasonable price. He's a great contractor and am glad I chose him. He's customer-focused, an expert in his craft, delivers a quality solution with integrity and attention to detail, works hard and cleans up fast. He started promptly Wednesday morning and was gone before I got home from work Thursday. He doesn't forget you after the project completes - he's quick to follow up with answers to any questions and backs up his work. If you have a water problem around your foundation - use AJ Waterproofing to fix it!

AJ was honest. I expected someone to try to sell me more of a remedy than I needed. AJ told me only what I needed to have done. He was neat, and clean up was beautiful. I would recommend this company.

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.
