Is 24/7 emergency service available for 21821?
Emergency requests are taken around the clock. Eastern time applies locally, and after-hours availability depends on the contractor on duty — genuine emergencies such as burning smells, smoke, sparks or water contacting live wiring are prioritised over routine work.
