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?"No license is on file under SAS Services, Inc. itself, though affiliated SAS entities hold active Residential Builder licenses. Ask which licensed entity will be on your contract and confirm it at LARA's license search.
  2. "Is basement waterproofing your core trade, and who does the drainage work?"SAS is multi-trade. Ask who on the crew specializes in waterproofing versus the masonry, concrete, or roofing lines, so the water diagnosis is done by someone who does it every day.
  3. "Is the warranty transferable if I sell, and what exactly does it cover?"In older, high-risk communities like the Grosse Pointes and Detroit, a transferable waterproofing warranty is a real selling point for the house.
  4. "Do you recommend a backwater valve for my block, and is it in the quote?"Much of their east-side service area sits in combined-sewer territory, where city-main backups, not just seepage, are the flood path. 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.
