How much does it cost to replace a fuse box professionally?

A professional fuse box replacement (upgrading to a modern breaker panel) is priced after an on-site assessment because code updates, service size, and site conditions drive the total. Most costs come from bringing the system to current electrical code and, when needed, increasing amperage to support today’s loads. Our licensed team handles permits and inspections across the Denver metro and can provide a flat-rate quote after evaluation. If you still have fuses, replacement is usually the safer long-term choice versus repair, especially if you’re adding EV charging, solar, or new HVAC. We also offer free second opinions on large installation projects, and Bell Perks members receive an extended 2-year labor and parts warranty on installed parts.

When we price your project, we look at:

• Panel size and amperage upgrade (e.g., 100A to 200A)
• Required code corrections or relocation clearances
• Service equipment work (meter, mast) and utility coordination
• Options like SPAN smart panels or whole-home surge protection
