People switch on lights and plug in/unplug lots of appliances each week. Electrical outlets and switches cause the most wear and tear on electrical systems. In fact, each time a device gets plugged in or unplugged, outlet connections in homes get increasingly weaker. This is problematic because loose electrical connections are not only a nuisance when a device stops working, but they are also a fire hazard. To address this, Mister Sparky’s electricians receive continual training on current codes and safety, making them the perfect electricians to update devices around the home.
