First, diagnose
On Ann Arbor's sloped, glacial-till lots, water often enters well away from where it pools, so an assessment has to follow the grade, not just the stain on the wall.
The full scope
- Entry point relative to the property's slope
- Grading that channels water toward the house
- Hydrostatic pressure from the glacial till
- Wall cracks versus floor-joint failure
- A record of when and where it appears
Worth noting locally
Ann Arbor's Old West Side sits on fill and glacial till old enough that an assessment often needs to consider the house's full construction history.
