"hands down the best in northwest NJ! Seidel electric was referred to me by a coworker with raving reviews when I was looking to put a generator into my newly purchased home. The owner (Steven) sat down in my kitchen for a long and thought out conversation and ended up doing a wonderful job for way less than the competition. Most recently my transfer switch was blown out by a power surge during a brown out. Steven and one of his electricians came out on their off time to make sure his customer was taken care of. They do great work, for great prices, and have even better customer service."
