How much does whole house surge protector installation cost?

Kanon Electric Inc provides upfront, job-based pricing for whole-home surge protector installation, confirmed after an on-site evaluation. Total cost mainly depends on your electrical panel’s capacity and condition, the surge protector’s rating, grounding quality, and any permitting or paired panel upgrades. We regularly install these at main panels throughout the South Sound and often coordinate them with panel work in homes around Federal Way. Installations are supported by an industry leading 5 year workmanship warranty and up to 10 years on certain materials, and we’ll provide the registration paperwork. Kanon Advantage Plan members receive 15% off and priority scheduling.

Signals that can affect price:

• No open breaker spaces or a damaged panel
• Outdated or inadequate grounding that needs correction
• Desire to combine the install with a panel replacement for efficiency

Schedule a licensed electrician to inspect your panel and grounding so you get the right device size and an exact written price. <br/> Updated: 2026-05-14 <br/> Need help in Federal Way, WA? Call (253) 200-4670 or book online.
