Advanced Basement Waterproofing is hired for wet basements: its Better Business Bureau profile lists basement waterproofing, foundation sealing and crack repair, French drain installation, hatchway repairs, mold remediation and restoration among the work it takes on. The BBB grades it A+ and lists it as an accredited business, accredited since April 2025. In a February 2023 Western Mass News segment on snowmelt flooding, sales manager Robert Giovanni spoke for the company's Chicopee operation.
The hiring record runs deep and is unusually consistent about who shows up. Seventy-three reviews spanning 2022 to 2026 sit behind a 4.8-star Google average from 77 ratings, and the same names recur across years — Konstantin (written by customers as Constantine or Kanstantin), Sergey or Sergei on the crews, and Brian on the sales side. What homeowners praise most often is the visit before the job: reviewers this spring and summer describe a thorough inspection, a plain explanation of where the water is actually coming from, and an estimate that came with education rather than pressure, including one who wrote that he was told exactly what needed doing with no attempt to upsell.
The larger jobs are described in detail too. Reviewers recount perimeter French drains feeding sump pumps, custom forms and six inches of poured concrete against bulging fieldstone walls in a 150-year-old basement (a 2025 review), and a full basement drain system plus two rebuilt rooms after storm damage (a 2024 review). Crews are repeatedly credited with protecting belongings from concrete dust and cleaning up daily, and in a 2025 account the team came back to reassess and redo about a third of a system that had leaked, under warranty.
What is worth pinning down before booking is the work that happens after the waterproofing. A June 2026 reviewer rated responsiveness excellent and price average but workmanship below average on the restoration, citing a missing wall penetration and recessed electrical sockets. A July 2025 one-star account describes paying over $13,000 for an interior system, then finding water past ankle depth in the basement and getting no reply to repeated attempts to reach the company. A December 2023 one-star says a $12,000 hatch-and-mold job left the hatch still leaking and the mold back, with an unresolved argument over appointment times, and a March 2023 one-star alleges masonry finished by hand rather than with proper tools and disputed billing for commute hours.
They are a reasonable call for diagnosing a wet basement and installing drains, sump pumps and mold remediation, especially if you want the problem explained before you commit. Get the restoration and carpentry scope written into the contract, confirm how warranty callbacks are handled, and verify the HIC registrations yourself with the state — the licence numbers on the BBB page are the directory's listing, not a verified credential.
