Precision Basement Waterproofing, LLC

Precision Basement Waterproofing is a Leominster-based basement waterproofing and foundation repair contractor — interior waterproofing, crawl space encapsulation, sump pumps, drain systems, dehumidifiers, and foundation crack repair — owner-operated by Nathan (Nate) Cerce across Worcester County and Central Massachusetts. Its Massachusetts home improvement contractor registration is active. French drains and sump pumps are the clearest specialty across three straight years of reviews. A June 2024 review describes french drains, a new sump pump with battery backup, and a vapor barrier installed for a basement that had needed a dehumidifier running 24/7, leaving it dry for the first time. A March 2026 review describes a drainage system and sump pump installed the same day a homeowner called about an urgent water issue, and an August 2024 review describes the crew working straight through two days to resolve a basement emergency. Reviewers consistently mention Nathan personally — showing up within 24 hours for an estimate, explaining the process clearly, and following through on the timeline he gives. Pricing comes up often and favorably: a March 2026 review describes getting the most reasonable quote after shopping around, and a 2025 review describes the company as the lowest bidder among several, with no attempt to upsell additional products. The office side gets praise too, with Kristal repeatedly named for managing scheduling and communication. All 36 reviews across Google and Thumbtack, from 2024 through 2026, are five stars, and recent activity is especially strong — seven reviews in the past six months, none negative. Thumbtack also lists Top Pro status for both 2024 and 2025 and a completed background check for Nathan. For basement waterproofing or a sump pump/drain system in Central Massachusetts, this is about as consistent a young company's record gets.
