Housing Age Profile

The median home in Kenilworth was built in 1956 - 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.

Cost Context: What Remediation Means for Kenilworth Homeowners

Remediation as % of home value 0.6%

Remediation costs in Kenilworth are relatively low compared to home values. The $2,000–$4,100 estimated range is a small fraction of median property value. Home values are 8% above the New Jersey average.

Lead Exposure Risk for Children in Kenilworth

90%
Homes Built Before 1986
0.002
mg/L Avg Lead (Limit: 0.015)

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.

Despite citywide averages serving as the standard public reference point, those aggregates cannot resolve what is happening at one specific faucet - and where 90% of Kenilworth homes come from before the solder rule or where utility samples sit at or above the action mark, the gap between system data and faucet reality matters more than it does in lower-exposure communities. An in-home draw closes that gap, with certified filtration through retailer networks available where confirmed faucet results warrant additional measures.

A/V Share of Claim-Record ZIPs

Historical NFIP data for Kenilworth contains 194 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $14,580. Among ZIP codes with claim records, 100% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.

How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. The <strong>$3,000</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.

Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
