The company states over 18,000 satisfied customers and that 85% of its business comes from referrals.
Not every basement problem is a waterproofing job. A strong sewage smell at a floor drain is usually a plumbing issue, call a licensed plumber. A bowing, cracked, or visibly shifting foundation wall is a structural issue, get a structural engineer before any water fix. A waterproofing contractor treats water intrusion, not the pipe or the wall itself.

Questions to ask this contractor

Based on the open items in this record and the risk profile of the area they serve
  1. "Who owns or manages the company day to day?"No owner or founder name is publicly confirmable despite the company's “family-owned” framing. Ask directly rather than rely on an unconfirmed name.
  2. "What is your Michigan license number?"We matched two Issued Michigan licenses: one held individually by Thomas Beauchemin since 1996, and a Maintenance & Alteration license registered under the DBA “Toms Basement Waterproofing.” Ask for the numbers and confirm them yourself at LARA's license search.
  3. "Which location and crew would handle my job, Chesterfield or St. Clair Shores?"This is a multi-location operation; confirm which team and which contract entity applies to your address.
  4. "What exactly does the written waterproofing guarantee cover?"They advertise a written, 100% satisfaction guarantee. Get the specific coverage and exclusions in writing. See our guide to choosing a contractor.
  5. "Do you recommend a backwater valve for my block, and is it in the quote?"Much of their Macomb-county service area sits in or near combined-sewer territory. See our combined-sewer overlay.
