Housing & Infrastructure in Mayville
With 76% 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.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
Pre-1986 plumbing is not a rare legacy case in Mayville - it's the dominant profile. The median build year of 1965 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Mayville were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Cost Context: What Remediation Means for Mayville Homeowners
Property equity in Mayville sits at a moderate ratio to estimated remediation costs - a classification that reframes the household financial perspective from routine maintenance to deliberate budgeting, where most homeowners have a realistic path to addressing documented water and safety issues if they map the financial commitment against available resources before committing to scope.
Remediation costs are moderate relative to home values in Mayville. The estimated $1,900–$4,800 range is manageable for most homeowners but still worth budgeting for. Home values are 15% below the Wisconsin average.
Lead Exposure Risk for Children in Mayville
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.
Older interior plumbing shapes the local picture: 76% of Mayville homes predate the federal solder ban, and aggregate sampling either approaches or crosses the action benchmark. That mix makes a single-home draw a standard pre-purchase or pre-occupancy step.

Historical NFIP Claim Context in Mayville
Historical NFIP data for Mayville contains 14 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $5,176. 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>$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.
