Homeowners unable to safely upgrade old doorbells lacking proper grounding

Homeowners with older properties face a dangerous electrical safety problem when trying to install modern doorbells—their existing wiring lacks grounding wires, creating shock hazards and code violations. DIY enthusiasts and homeowners lack clear guidance on whether to attempt the upgrade themselves or hire expensive electricians, and existing solutions either require costly rewiring or leave safety gaps. Current resources are fragmented across forums with conflicting advice, leaving people uncertain about safe, code-compliant solutions.
