Housing & Infrastructure in Redmon
With 81% 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
Two dates define the high-risk tiers of residential plumbing from a lead standpoint: 1970, before which lead pipes were commonly installed for service connections, and 1986, before which lead solder was standard in copper plumbing. A median build year of 1959 places Redmon's housing distribution well within that older risk zone. The bar chart above breaks down how much of the stock falls into each era — and the pre-1986 share alone represents more than half the residential inventory, making plumbing-era risk a defining characteristic of the local water safety picture.
Over half of homes in Redmon 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 Redmon Homeowners
The Redmon equity share sits above the low tier but short of the range where remediation becomes a heavy financial burden — the cost-to-value ratio is moderate, and deliberate planning is the key practical lever for most homeowners.
Remediation costs are moderate relative to home values in Redmon. The estimated $800–$1,500 range is manageable for most homeowners but still worth budgeting for. Home values are 58% below the Illinois average.
Lead Exposure Risk for Children in Redmon
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.
Wherever 81% of local housing was built before solder rules changed — as is the case in Redmon — a faucet-level sample closes the gap that aggregate utility data cannot.

What You Can Do in Redmon
