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. "What is your Michigan license number?"We matched an Issued Residential Builder license registered as MI BASEMENTS LLC in the state's LARA record. Ask for the number and confirm it yourself at LARA's license search.
  2. "Will owner Chris Roumayah or a project manager be on my job?"Michigan Basements is a family-run company (owner Chris Roumayah, per its BBB profile). For a company this size, knowing who stands behind the warranty matters.
  3. "Is the lifetime warranty transferable if I sell, and what exactly does it cover?"Listings cite a lifetime transferable warranty. Get the coverage and transferability in writing, especially in older, higher-risk communities.
  4. "For my block walls, do you drill weep holes, and do you recommend a backwater valve?"Their system uses weep holes and interior drainage. In combined-sewer areas a backwater valve addresses city-main backups too. See our combined-sewer overlay.
  5. "Can I get the diagnosis and itemized scope in writing before signing?"Our guide to choosing a contractor covers how to compare quotes and the red flags to watch.
