Last 6 months: 3 reviews, 0 negative. ## The honest read An April 2026 Angi reviewer had the basement waterproofed by Groundworks over a 3 day visit and wrote that foreman Doug kept them in the loop, found solutions to fit the basement layout and came with a financing option, a 5 year warranty and a yearly inspection plan. The New Hampshire company, formerly Rescon, does foundation repair, basement waterproofing, crawl space work and sump pump installation and service; its reviews also describe an egress window, crawl space insulation and lifting a pool deck. On Google it holds 4.9 stars from 49 ratings, with 4.8 from 94 ratings on Thumbtack, and BBB gives it an A+. A November 2025 Google reviewer said a crew with a jackhammer did the basement sump pump job in five hours. A March 2026 Angi reviewer complained that the crew smelled of weed, that holes were left in the yard with no follow-up after an offer to fill them, and that digging around the chimney appears to have broken it, which the company denies. A July 2024 Google reviewer said an installed sump pump failed and corroded in less than a year. On Reddit in May 2025, a commenter said Rescon put a sump pump outlet at the edge of their leech field. **Strengths:** - Waterproofing — an April 2026 reviewer said foreman Doug found solutions to fit the basement layout - Sump pumps — a November 2025 reviewer said a basement sump pump job took five hours - Emergency service — a December 2019 reviewer was called back within an hour on the emergency line **Concerns:** - Site damage — a March 2026 Angi reviewer reported unfilled holes and a chimney that appears broken after digging - Sump pump failure — a July 2024 Google reviewer said an installed pump failed and corroded within a year ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - An April 2026 reviewer described a 3 day basement waterproofing with a 5 year warranty and yearly inspection plan _(confidence: high)_ - [Angi](https://www.angi.com/companylist/us/nh/londonderry/rescon-basement-solutions-llc-reviews-1.htm) — “Just finished a visit with Foreman Doug and his crew, Devin, Sean, and Mason.
