How Old Is Sheldon's Housing Stock?
With 71% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Heavily weighted toward older construction, Sheldon's housing stock carries a median build year of 1977. That profile puts a majority of homes in the era when lead-soldered copper plumbing was standard practice.
Over half of homes in Sheldon were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Sheldon: Remediation Cost in Perspective
While no remediation project is entirely without cost, the relationship between estimated remediation and property values in Sheldon is notably favorable — the equity share is small enough that the household financial perspective is one of proportionality rather than pressure, and most homeowners can treat it as routine planning rather than a significant financial event.
Remediation costs in Sheldon are relatively low compared to home values. The $300–$2,300 estimated range is a small fraction of median property value. Home values are 41% below the Wisconsin average.
Protecting Children from Lead in Sheldon
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Routinely in Sheldon, where 71% of housing predates the solder ban and aggregate utility readings hover near the federal threshold, a faucet-level draw functions as a standard household step for families with small kids.
