Diagnose before you buy anything
The patch you can see is rarely the whole job -- a real plan also traces the water entry point, checks humidity, evaluates material condition, sets up containment, and verifies the fix afterward.
What the written scope should cover
- Existing conditions and likely cause
- Preparation and protection
- Materials, compatibility, and installation details
- Permits, testing, cleanup, and restoration
- Exclusions, warranty terms, and change-order process
Sterling Heights context
Finished basements are common in Sterling Heights' postwar housing stock, which means contained mold removal often has to work around drywall, flooring, and mechanical runs installed well after the original 1950s-70s construction.
