Start with conditions, not a product
The part that matters most never shows: drain position, framing, how the waterproofing transitions are detailed, ventilation, wiring capacity, and access all decide the real scope of work.
Build a complete scope
- What the supply and waste lines turn out to be once a wall is opened
- Whether the service line material for the property has been established
- Waterproofing behind tile and the inspection before it is covered over
- Whether the layout change reaches structure in an older floor plan
- Which permits apply, when inspectors attend, and what workmanship cover says
Flint context
Flint blends historic auto-era neighborhoods like Civic Park and Carriage Town with mid-century subdivisions, homes along the Flint River corridor, and newer construction farther from downtown. Slow-draining Genesee County clay, plumbing and drain lines that often date to the city's early-20th-century industrial boom, humid summers, and long snowy winters reward careful diagnosis before scope.
