Housing Age Profile
The median home in Claytonville was built in 1903 — a figure that places most of the city's residential stock in the era when lead solder was still standard in copper plumbing. Homes built before 1986 may have lead-soldered joints; those built before 1970 face the additional possibility of lead pipes in the service line itself.
Over half of homes in Claytonville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Claytonville Homeowners
The Claytonville remediation share exceeds what lower-tier markets face — the cost-to-value ratio here is elevated, and the household financial perspective reflects a commitment that most homeowners need to plan for explicitly.
At 2.6% of home value, remediation costs in Claytonville represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $800–$1,500. Home values here are 75% below the Illinois average.
Lead Exposure Risk for Children in Claytonville
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.
95% — that captures the slice of Claytonville housing dating from before the federal ban on solder containing lead. It pairs with aggregate utility readings that either approach or cross 0.015 mg/L, the benchmark set under the EPA Lead and Copper Rule. Together, the two figures shift one-home reads into a standard household-level confirmation, particularly for families with kids. A certified lead-removal filter is available through retailer-verified channels if a kit returns results that warrant additional measures.
