Hanover Park sits in two counties at once. Homeowners get confused about which authority handles their chimney permit, so here is the short answer.
Hanover Park incorporated in 1958 and straddles the Cook and DuPage county line, with Lake Street, Irving Park Road, and Barrington Road as the main corridors. The village was built out as planned postwar housing through the 1960s and 1970s, with later sections continuing into the 1990s.
The county split causes real confusion. Your property tax bill and your county records come from either Cook or DuPage depending on which side of the line you sit, but your building permit does not. The Village of Hanover Park issues chimney permits for every address in the village regardless of county.
The housing itself is consistent with the era. Exterior side-wall chimneys on ranches and split-levels dominate the older sections, and the newer areas moved toward framed chases with metal flues.
Each architectural period in Hanover Park has predictable chimney failure modes after enough decades of weather. Here is what to look for.
The original Hanover Park subdivisions have exterior masonry chimneys now approaching 60 years old. Joint erosion on the weather-facing elevations is the norm, and the brick underneath is usually still sound. This is standard repointing work, not structural rebuilding, as long as it is caught before the joints open enough to let water reach the flue.
Stepped rooflines mean more flashing seams per chimney. In Hanover Park the most frequent cause of a fireplace-area ceiling stain is failed step flashing, not a cracked crown. The two look identical from inside the house and are very different repairs.
Later sections used metal flues in framed chases. Chase covers from this period are typically 30 plus years old now and rusting. Replacement is straightforward and cheap relative to the framing repair that follows if it is left.
Structurally sound, but the wear items are aging. Caps lose screens, covers begin to pond, and the flues need an annual Level 1 inspection to stay ahead of it.
Hanover Park chimneys are repairable in the large majority of cases. Sixty-year-old mortar on sound brick is maintenance. The decision tips toward replacement only when water has been getting past the joints for years.
