River city
The Saginaw River divides the city into east and west sides just upriver from Saginaw Bay. The first log cabin was built in 1831, the town was established in 1837 and became a city in 1865. Lumber, milling and shipbuilding drove the boom of the late 1800s, and the Center Avenue Historic District has more than 250 buildings on the National Register, many of them lumber-era houses.
What old Bay City houses need
Walls with nothing in them, attics with a few inches of old fill and open wall tops, and rim joists on fieldstone or early block foundations. We seal and insulate the attic first, dense-pack the walls, then foam the rim and sill.
West Side history
West Bay City was formed in 1877 from the villages of Banks, Salzburg and Wenona. Many of the older homes on the west side date from those settlements and share the same construction.
