How much does it cost to replace a whole-house surge protector?

The cost to replace a whole-house surge protector is confirmed after an on-site assessment because pricing varies by panel type, service size, and any code updates needed. Most replacements are simple panel-mounted devices, but access, main breaker rating, and grounding quality can change labor and materials. In our work across the Salem–Roanoke area, panel brand and existing grounding are often the biggest swing factors. We provide upfront, fixed pricing before work begins.

Key factors that influence replacement price:

• Service amperage (100/150/200A) and the surge protector’s required rating.
• Panel brand/model compatibility or need for a breaker-style SPD.
• Grounding and bonding corrections to meet current code.
• Permit and inspection requirements set by your locality.

If you notice scorch marks, a burning odor, or repeated SPD trips after storms, turn off the main breaker if safe and call a licensed electrician.
