Housing & Infrastructure in Madisonville
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
For most of Madisonville's housing stock, construction occurred after 1986 - when lead solder in plumbing was federally prohibited. The median build year of 2003 broadly reflects that newer profile.
Most homes in Madisonville were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Madisonville Homeowners
Setting Madisonville remediation figures against its property market, the resulting ratio sits comfortably in the low tier - a classification that reflects the kind of household financial position where most homeowners can identify documented issues, schedule the work, and absorb the cost without it registering as a significant budget disruption.
Remediation costs in Madisonville are relatively low compared to home values. The $1,200–$2,500 estimated range is a small fraction of median property value. Home values are 129% above the Louisiana average.
Lead Exposure Risk for Children in Madisonville
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.
Generally, the structural picture for Madisonville runs in a quiet direction. Aggregate sampling rests under the federal action benchmark, and 10% of housing comes from the pre-rule era - a contained local footprint. That dual signal keeps lead in the background of local concerns, while a one-faucet measurement still answers a different question than any system average can: what is actually flowing from one specific tap on a given morning.

Historical NFIP Claim Context in Madisonville
Historical NFIP data for Madisonville contains 1,205 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $34,841. 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>$1,800</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.
