Editorial summary
Matrix Basements is listed in Grand Rapids at 400 Ann St NW as a basement waterproofing contractor. The source data shows crawl space waterproofing as the only explicitly named service, along with a free inspection and financing. It also shows a strong review profile: 4.9 stars from 71 Google reviews, plus 17 years in business. For directory readers, that makes this a straightforward local waterproofing record with solid trust signals and a clear crawl-space focus. The listing is best understood as a moisture-control and waterproofing profile rather than a broad home-improvement catalog. The Google category is Remodeler, while the directory category is Basement Waterproofing Contractor, so the record is being indexed for waterproofing even though the platform category is broader. That distinction matters for homeowners searching specifically for crawl-space help. The supplied website is present, and a phone number is also marked as present, but no service-area text was provided. Because of that, the safest reading is that the company is associated with Grand Rapids from the listing address, without assuming wider regional coverage. The source also does not provide details on methods, materials, warranties, or any specific drainage or mold-related services beyond crawl space waterproofing, so those should not be inferred. Overall, this is a useful local entry for people looking for crawl space waterproofing in Grand Rapids and wanting a provider with a long operating history, a high Google rating, and an inspection option before work begins.
