Editorial summary
Pierman is listed in Muskogee, Oklahoma, at 1004 Gibson St, and the record points clearly toward crawl-space and basement moisture work. The service list includes crawl space encapsulation, crawl space waterproofing, and drainage systems. That combination fits the kinds of problems homeowners often investigate when they are dealing with standing water under a house or excess moisture in a crawl space. The public review profile is modest but positive: 4.8 stars from 8 Google reviews. The listing also shows a phone number, which is helpful because no website was provided. Other details are limited. There is no service-area text, no years in business, no financing note, and no free-inspection information in the source record. Because the directory category is construction company rather than a more specific waterproofing designation, the services matter here. Encapsulation, waterproofing, and drainage systems are the clearest signals of what this business handles. The record does not mention sump pumps directly, though the related search topics include that topic as related homeowner search behavior rather than a confirmed service.
