Why Keego Harbor homes face basement risk

Basement risk in Keego Harbor comes down to two things: how old its houses are and the clay beneath them. With some of its homes, 31%, built before 1960 and the biggest share going up in the nineteen-seventies, many sit on original clay drain tile, and southeast Michigan's dense clay holds water against those foundations rather than letting it drain.

How Keego Harbor compares

Keego Harbor's Index of 35 ranks #64 of 116 communities region-wide and sits below the metro Detroit median of 37. It runs higher than its nearby neighbor West Bloomfield Township.

Does insurance cover it?

Often not. Standard Michigan homeowners policies commonly exclude sewer backup and groundwater unless you carry a specific endorsement. Before the next storm, it is worth reading our guide on whether insurance covers sewer backup in Michigan and checking your declarations page.

What to do about it

  1. Compare your block on the metro map to see how your specific area compares within the community.
  2. Walk the basement after the next hard rain for dampness, white mineral lines, or a musty smell.
  3. Extend downspouts and check grading so water flows away from the foundation. More on keeping a basement dry.
