Precision Basement Waterproofing, LLC

Precision Basement Waterproofing is a small, owner-operated crew out of Leominster built around one name: Nathan Cerce, called "Nate" by nearly every customer who writes about him. The company handles interior waterproofing, sump pumps, French drains, crawl space encapsulation, dehumidifiers and foundation crack repair across Worcester County and Central Massachusetts, from Fitchburg to Lowell. Across 36 reviews on Google and Thumbtack, every one is 5 stars, with eight more added in just the last six months and none of them negative. Customers describe specific work, not just praise: in a 2024 review, one homeowner detailed a full French drain system with clean-out ports, a new sump pump and vapor barriers that finally kept a basement dry after years of running a dehumidifier around the clock. Another 2024 review described a two-day push through an active flooding emergency, and a March 2026 review recounted a same-day arrival to size up an urgent sump-pump job. On Thumbtack, Nathan Cerce holds a completed background check and the platform's Top Pro badge for both 2024 and 2025. Its Massachusetts home improvement contractor license is active. Several reviewers specifically call out transparent, no-upsell pricing — in a 2025 review, one customer who shopped several companies said Precision came in as the lowest bidder and didn't push extra add-ons. For anyone in Central Massachusetts dealing with water in the basement or garage, this is a small shop with an unusually consistent multi-platform record on Google and Thumbtack alike — worth calling early, since a crew this size can book up.
