Once & Done Waterproofing Solutions LLC operates from Martinsburg, West Virginia, delivering basement and crawlspace waterproofing services to homeowners across the Eastern Panhandle region. The company holds a perfect 5.0-star rating assembled from 36 client reviews, reflecting consistent delivery of dry spaces and Structural Protection. Their service territory encompasses Martinsburg and Mercersburg in West Virginia alongside Allentown across state lines in Pennsylvania. The team specializes in sealing fieldstone, concrete block, and cement foundations that experience dampness or full flooding, addressing both residential basements and commercial rental properties.
The contractor distinguishes itself through a lifetime warranty on all interior waterproofing products, a guarantee that transfers with the structure rather than remaining tied to the original homeowner. Their technicians bring over 40 years of combined industry experience, applying specialized knowledge in French drain installation, sump pump systems, foundation drainage engineering, and complete crawlspace encapsulation. The company emphasizes honest assessment over aggressive upselling, presenting multiple solution options and explicitly identifying features a customer does not need something competitors routinely omit.
Reviewers document specific technicians delivering exceptional service. Shawn conducted a free foundation consultation and provided honest reassurance that a discovered crack posed no immediate concern, declining to manufacture expensive repairs. Another customer described Jeff offering several options without recommending unnecessary upgrades, then walking the job alongside his crew to ensure proper execution. A third client noted the team protected hard flooring surfaces during work and returned to verify everything met specifications. These accounts collectively emphasize the contractor's commitment to honest representation, careful property handling, and follow-through after the initial scope completes.
What Customers Say
All 36 reviews award five stars, with customers repeatedly citing honest assessment, no unnecessary upselling, and fair pricing as distinguishing qualities. Seven reviewers specifically name individual technicians, with Shawn receiving three mentions for consultation transparency and Jeff gaining two references for presenting options without pressure.
