Editorial summary
A J Waterproofing is a Collegeville basement waterproofing contractor located at 3774 Kratz Rd. The business is listed as a waterproofing service and supports a broader set of moisture and structural repairs, including crawl space repair, crawl space waterproofing, foundation repair, mold remediation, drainage systems, and sump pump services. Its profile also notes a free inspection option and financing, which can matter to homeowners comparing repair timelines and budgeting before work begins. The company shows 30 years in business, along with a strong Google rating of 4.8 from 168 reviews. That combination gives the listing a substantial amount of public proof compared with thinner local records. The company website is available, and the profile includes 24/7 availability in its service-area text, though the exact scope of service coverage is not otherwise detailed here. For homeowners dealing with issues such as standing water under a house, sagging floors, or crawl space moisture, the service mix suggests a contractor with both water-control and structural-repair experience. Because the record does not provide a license number, warranty language, or a full service-area breakdown, those details should not be assumed. Still, this is one of the more complete listings in the set, with enough evidence to support a solid directory summary and search presence for Collegeville and nearby basement waterproofing searches.
