Watch for Signs
What are the warning signs that tell you there may be a problem with your wiring and you should bring in a pro? Flickering lights. Breakers that always trip. Fuses that always blow. A burning smell coming from appliances or in rooms. Discoloured wall outlets. Outlets that spark. Outlets and switches that are hot to the touch. They're all signs that tell you something is wrong with the electrical in your home.
