Neither predominantly new nor predominantly old, the stock presents a moderate aggregate risk environment - with individual risk varying sharply depending on when and where a specific home was built.
Most homes in Grosse Tete were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

The <strong>$1,500</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.
