Crystal Lake Elementary District 47 is taking a thoughtful, phased approach to one of the most pressing challenges facing many school systems today: deferred maintenance. With a significant backlog of facility needs across the district, leaders have prioritized improvements that strengthen building performance, address safety concerns, and support the long-term stewardship of existing schools.
Over five years, that work included a series of targeted projects focused on aging infrastructure, interior finishes, and Health/Life Safety needs. Early improvements addressed miscellaneous door and window replacements and ADA upgrades across multiple schools. In 2022, the district advanced major HVAC work, including full heating and cooling system replacements at Husmann Elementary School and Lundahl Middle School, as well as central heating and cooling plant replacements at Woods Creek Elementary School.
More recent projects have continued that momentum while expanding the focus to security and occupant comfort. Secure entry improvements completed in 2024 at South Elementary School and Lundahl Middle School renovated main office areas to create safer visitor entry sequences while modernizing associated office spaces. In 2025, the district completed another round of health and life safety and cooling improvements across multiple buildings, including independent cooling equipment for individual rooms, door replacements, wall reconstruction to improve fire ratings, ventilation added to repurposed spaces, masonry repairs, and additional ADA upgrades.
That long-range effort is set to continue in 2026 with a full heating and cooling system replacement at Bernotas Middle School and additional health and life safety improvements at North and West elementary schools. Together, these projects reflect a clear commitment to maintaining and improving the district’s existing facilities through strategic, phased investment.
