Editorial summary
Streamline Waterproofing is listed in Londonderry at 114 Rockingham Rd as a basement waterproofing contractor. The directory fields show two crawl-space services: crawl space waterproofing and vapor barrier installation. That gives the listing clear relevance for moisture-control searches, but the record does not go beyond those two service items. The Google profile shows a 4-star rating from 3 reviews. That is a very small review sample, so it offers only limited insight into customer experience. The Google category is general contractor, while the directory category is basement waterproofing contractor, so the service fields are the most reliable part of the profile for homeowners comparing local crawl-space help. No website was provided, and there is no service area text, financing detail, free-inspection note, or years-in-business information in the supplied data. Because the listing is thin, it should be read as a straightforward local moisture-control entry rather than a fully documented company profile. The source data does not mention foundation drainage systems, sump pump installation, mold work, or broader crawl-space encapsulation, so those services should not be assumed from this record alone.
