How Old Is Wilmer's Housing Stock?
Housing age data helps assess potential lead pipe and infrastructure risks. Newer housing stock generally means lower plumbing-related contamination risk.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Two regulatory milestones define plumbing-era risk in residential housing: 1970, when lead pipes were still commonly installed for service lines, and 1986, when lead solder was banned from new copper plumbing. A median build year of 1993 places Wilmer in the middle zone between those thresholds — with a meaningful share of housing predating both cutoffs. The distribution shown above breaks out those eras explicitly, clarifying where concentrated risk sits across the residential inventory.
Most homes in Wilmer were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Wilmer: Remediation Cost in Perspective
Cost-to-value data for Wilmer produces a high remediation-share classification — the equity impact here is elevated, placing this market in the tier where financial preparation is a meaningful factor in how homeowners approach documented issues.
At 2.2% of home value, remediation costs in Wilmer represent a significant financial burden. For homes valued near the median, fixing water and safety issues could cost $1,500–$3,300. Home values here are 54% below the Texas average.
Protecting Children from Lead in Wilmer
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.
If 32% of the Wilmer inventory comes from before the federal ban on lead-bearing solder — and if utility samples sit at or near 0.015 mg/L — the gap between citywide averages and one specific faucet becomes a practical concern rather than a theoretical one. That is why one-home reads exist as a separate measurement. A certified filter through retailer networks addresses confirmed exposure where it appears in a household.

Climate-Related Water Risk for Wilmer
FEMA data shows 100% of Wilmer's ZIP codes mapped into designated flood zones, paired with an NFIP record of 1 claim. That footprint places local flood exposure in the range where it warrants attention without rising to high-severity planning territory.
Wilmer has a moderate flood history with 1 FEMA claims. 100% of ZIP codes fall within FEMA flood zones. Flood events can contaminate drinking water and overwhelm treatment systems.
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. Flood damage can add significantly to the estimated <strong>$2,300</strong> remediation cost per household.
Residents in flood-prone areas should consider flood insurance even outside FEMA zones — over 25% of flood claims come from low-to-moderate risk areas. After any flood event, test your water before drinking.
