How Old Is De Forest's Housing Stock?

Median Build Year
45%
Built Before 1986

Likely Pipe Material

With 45% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.

Housing Age Profile

Some cities skew heavily toward one construction era; De Forest does not. The median build year of 1981 reflects a housing stock where older and newer homes share the market in meaningful proportions. That mixed profile means the city carries moderate aggregate plumbing-era risk - with older homes, particularly those built before 1986, representing the portion of the stock where lead-soldered joints may still be present.

14%
Pre-1970 (Lead Pipes Risk)
Pre-1970 (14%) 1970–1986 (31%) Post-1986 (55%)

Most homes in De Forest were built after 1986, reducing the risk of lead contamination from plumbing. Older homes should still be tested.

De Forest: Remediation Cost in Perspective

Setting De Forest 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.

Median Home Value
$355,700
Est. Remediation
$3,000
Remediation as % of home value 0.8%

Remediation costs in De Forest are relatively low compared to home values. The $2,000–$4,000 estimated range is a small fraction of median property value. Home values are 54% above the Wisconsin average.

Protecting Children from Lead in De Forest

45%
Homes Built Before 1986
0.006
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.

If 45% of the De Forest 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.

Historical Flood-Claim Evidence for De Forest

14
Total FEMA Flood Claims

Avg Reported Sum With Payment Data
0%
A/V Share of Claim-Record ZIPs

Historical NFIP data for De Forest contains 14 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $43,298. Among ZIP codes with claim records, 0% 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.

What You Can Do in De Forest
