Hardwired • Interconnected • Combination Units • Code Compliant
A working smoke detector is one of the few things in a home that pays for itself the first time it actually has to do its job. That's the lens we work through at Union Electrical Service. Not "another box on the ceiling" — a code-compliant, properly placed, properly wired early-warning system that homeowners and property managers across Stewartstown can rely on without thinking about it.
Most installations we handle in Stewartstown, PA fall into two camps: people upgrading older battery units to hardwired interconnected systems, and landlords or buyers needing detectors brought up to current code before a sale, inspection, or lease. Both deserve more attention than the average handyman gives them.
