Review by in Haverford, PA
Work Performed: Seal 8 foot crack in basement wall (that three prior handymen failed to fix). My wife and I are long time university faculty members, and have graded hundreds of assignments. The across the board 5-star rating for Main Line Waterproofing is anything but grade inflation. We were still getting water on the basement floor via this crack. Herb, the owner, personally and promptly visited us, inspected the wall, diagnosed the issue, and suggested a solution that the prior three handymen had not even considered. We learned that it pays to go to a specialist. We signed up on the spot and the repair men, Mark and John, arrived soon thereafter. We were so impressed with the care they gave to our home, so fastidious about being neat and clean – both in preparation and finishing up. I am not very skilled in the trades but I am very interested. When asked if I could observe, the men were very inviting, with Mark clearly explaining each step of the fascinating process. I wasn’t checking up on them, rather I was learning, and they were fine and welcoming teachers. Now it is a month later and we’ve had heavy rain storms. Result: Problem solved. Cost very reasonable. Experience very pleasant. (10 year warranty to boot). Grade: Out and out A+ Thank you Main Lime Waterproofing! John & Nancy, Haverford, PA

The owner was very responsive and was able to come to the house and give us an estimate within 2 days. After the work was completed, he came back to the house to review when we had questions. I would highly recommend this company.

Review by in Reading, PA
We could not be happier with the work Mainline waterproofing did. They diagnosed our problem, offered solutions, and completed the work with extraordinary professionalism and skill. We had a French drain installed, moldy wood removed, and our walls waterproofed. Nicole (office manager), herb (owner), and Peter (foreman) were in constant contact with my husband and I leading up to and throughout the job. They even worked with us to make a last minute change at our request. The phrase I heard from each of them was "our top priority is customer satisfaction". I would very highly recommend them for the quality and value of work!

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.
