Pricing to replace a whole-house surge protector isn’t one-size-fits-all. It depends on the unit’s Joules rating, compatibility with your electrical panel, and any wiring or panel work needed. A Cardinal technician will assess your system on site and provide a firm quote. If your device shows an end-of-life light or you’re seeing frequent breaker trips, replacement is likely. First-time customers can get $25 off a new whole-house surge protector installation, and financing is available. We serve Madison, Sun Prairie, and nearby areas.

It’s not recommended. Whole-house surge protectors tie into your main electrical panel, and panel work is hazardous if you’re not a licensed electrician. Our licensed, background-checked technicians assess your system, recommend the right unit, and install it so it integrates correctly. We also replace worn devices and provide maintenance to check status lights and connections. Service is available in Madison and Sun Prairie.
