Housing Age Profile
The median home in Stockport was built in 1901 — 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 Stockport were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Stockport: Remediation Cost in Perspective
When the numbers for Stockport are taken together, the remediation share is clearly in the elevated category — most homeowners here are weighing a commitment that extends beyond routine property upkeep, and the practical value of documenting scope early, prioritizing by urgency, and mapping costs against the household budget is proportionally higher at this tier.
At 2.2% of home value, remediation costs in Stockport represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,100–$2,300. Home values here are 53% below the Iowa average.
Protecting Children from Lead in Stockport
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.
Older interior plumbing shapes the local picture: 82% of Stockport homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.
