What Detroit homeowners should know
Detroit has a large stock of homes built from the 1910s through the 1950s, many with full basements, brick construction and aging plumbing. Cold winters with freeze-thaw cycles, heavy summer storms and an aging combined sewer system make basement flooding one of the most common and costly problems.
Storms in summer 2021 flooded thousands of Detroit-area basements, and many homeowners have since added backwater valves, battery-backup sump pumps and sewer-backup coverage.
