Housing & Infrastructure in Windsor
With 82% 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
Pre-1986 plumbing is not a rare legacy case in Windsor — it's the dominant profile. The median build year of 1966 indicates a housing stock where lead-soldered copper joints are a common structural feature of residences across the city.
Over half of homes in Windsor 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 Windsor Homeowners
Middle of the range — Windsor homeowners face a remediation share that calls for real financial attention without reaching crisis territory.
Remediation costs are moderate relative to home values in Windsor. The estimated $1,250–$2,900 range is manageable for most homeowners but still worth budgeting for. Home values are 31% below the Illinois average.
Lead Exposure Risk for Children in Windsor
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: 82% of Windsor 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.
