1960s-1980s
Mid-century split-level and contemporary
Multi-elevation roofs in Long Grove's mid-century stock create complex flashing geometry around chimney penetrations. Flashing failures are the most common source of interior water damage that homeowners trace to the chimney.
1980s-2000s
Custom estate
Long Grove estate homes typically feature substantial masonry chimneys, often with decorative caps and corbels. Annual NFPA 211 inspection is the right cadence.
1980s-2000s
Prefab metal flue and chase construction
Many newer Long Grove homes use prefabricated metal flues with manufactured chimney chases instead of structural masonry. These need annual NFPA 211 Level 1 inspection, chase cover replacement, and cap replacement, not the structural repair common in older stock.
1950s-1970s
Ranch and split-level
Side-of-house exterior chimneys take maximum freeze-thaw exposure. In Long Grove mortar joints and flashing fail before the brick itself. Repointing on a 30 to 40 year cadence is normal for this stock.
