Housing & Infrastructure in Caldwell
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
When a home in Caldwell was built matters for lead because federal rules adopted in 1986 limited how much lead new plumbing could contain; the local median build year is 1997. A median sits in the middle of a range, so some homes are older and some newer, and past repairs may have changed the pipes in either group. A plumber can identify the materials inside a home, and a lab test measures what reaches the tap.
Most homes in Caldwell were built after 1986; lead exposure at a tap still depends on its service line and plumbing. Older homes should still be tested.

Cost Context: What Remediation Means for Caldwell Homeowners
Compared with typical property prices, the remediation estimate for Caldwell is small in percentage terms - at or under one percent.
Estimated remediation costs in Caldwell can be compared with local home values. The $450–$1,400 estimated range can be set against the median property value; actual costs vary by home. Home values are 13% below the Texas average.
Lead Exposure Risk for Children in Caldwell
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.

Historical NFIP Claim Context in Caldwell
Historical NFIP data for Caldwell contains 13 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $22,698. 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 $800 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.
