Basement risk where they work
Their stated service area, colored by the Basement Risk Index · 0–100
Highest-risk communities they serve
Their service area spans some of metro Detroit's oldest, highest-risk housing, Detroit (92), Wyandotte (79), and Allen Park (77), where interior drains and backwater valves matter most, alongside newer, lower-risk suburbs like Canton (3) and Rochester Hills (13). Detroit's score blends real City of Detroit 311 flood records; the suburbs are modeled from housing age and labeled as such. See methodology or the full 116-community ranking.
Questions to ask this contractor
Based on the open items in this record and the risk profile of the area they serve
- "What is your Michigan residential builder license number?"Their site states "fully licensed and insured," but we have not yet matched a license number in the public LARA record. Any legitimate contractor will give it, then verify it free at LARA's license search.
- "What legal business name will be on my contract?"Public listings show more than one name for this business. The name on the contract is the one your warranty lives with.
- "Is the warranty transferable if I sell, and what exactly does it cover?"In older, high-risk communities like Detroit, Wyandotte, and Allen Park, a transferable waterproofing warranty is a real selling point for the house.
- "Do you recommend a backwater valve for my block, and is it in the quote?"Much of their service area sits in combined-sewer territory, where city-main backups, not just seepage, are the flood path. See our combined-sewer overlay.
- "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.
