Once & Done Waterproofing Solutions

Once & Done Waterproofing Solutions describes crawl-space encapsulation and waterproofing and identifies Martinsburg, West Virginia as an office locality. Its company website publishes 888-589-9651. The company also lists Pennsylvania locations; those are treated as parts of the same business. The crawl-space description includes a vapor-barrier liner, vent sealing and drainage when needed to address standing water. It also mentions insulation installation. The company says recommendations depend on the crawl space, so ask for a property-specific proposal rather than assuming that every listed component is included. Clarify preparation, liner coverage, drainage discharge, any equipment, cleanup and future maintenance in the written estimate. Installation wording alone does not establish that removal of existing insulation is included. Ask how any existing materials or obstructions will be handled and whether those tasks are included in the price. Confirm how changes to the written proposal will be handled. A separate basement service page describes basement waterproofing. The service-area page lists Berkeley, Jefferson, Morgan and Hampshire counties in West Virginia. Those are company-reported coverage statements; confirm availability for the property's address and the requested work directly. A first-party street address, ZIP code and public business email were not established in the reviewed text. The Martinsburg office statement does not establish visitor access. Reviewed October 12, 2026 using company-published web extracts. The homepage extract reported a one-day crawl age, the crawl-space page two months, the coverage page four months and the basement page six months. These are retrieval qualifications, not verified page-update dates. Current availability, credentials and workmanship have not been independently verified.
