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

How Remediation Costs Compare in Allison
Within the Allison property market, documented remediation claims a moderate slice of typical equity — real but budgetable.
Remediation costs are moderate relative to home values in Allison. The estimated $0–$800 range is manageable for most homeowners but still worth budgeting for. Home values are 84% below the Pennsylvania average.
Allison: Lead Risk & Vulnerable Populations
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.
Confirming what arrives at a specific faucet is something utility-side averages cannot do. With 95% of Allison stock built before the lead-solder ban and citywide monitoring at or beyond the regulatory mark, a tap-level kit fits the standard diligence picture.
