Housing Age Profile
The character of Star Lake's housing stock is one of deep historical layering — a median build year of 1979 signals a city built largely before the plumbing era changes of 1986 and 1970. Lead-soldered copper joints and, in the oldest properties, lead service lines are commonly present in this inventory. That context shapes what individual water testing may reveal, particularly in neighborhoods where the oldest housing is concentrated.
Over half of homes in Star Lake 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 Star Lake Homeowners
Across Star Lake, the equity share taken up by estimated remediation is small — a favorable ratio for most property owners.
Remediation costs in Star Lake are relatively low compared to home values. The $0–$800 estimated range is a small fraction of median property value. Home values are 1% below the Wisconsin average.
Lead Exposure Risk for Children in Star Lake
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.
65% — that captures the slice of Star Lake 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.
