Hospitals can’t shut down. A patient room, an ICU wing, an operating suite — these spaces must stay operational while the work above them happens. F.J. Dahill has been a roofing and envelope contractor for Connecticut healthcare facilities for decades, including work for Yale-New Haven Health and Hartford HealthCare. We bring the infection-control protocols, the ICRA-compliant containment, after-hours scheduling, and the documentation that hospital facility teams require, and the craftsmanship that protects patients from the work above them.
