A professional fuse box replacement (panel upgrade) typically costs $1,500 to $6,500, including permits and code compliance. Price varies with amperage increase (for example, moving from 100-amp to 200-amp), panel condition, relocation needs, and how much code updating is required. Most projects take 6–10 hours and are usually completed in one day. Our licensed electricians handle permits and inspections as part of the service, with up-front flat-rate pricing and no hidden fees. We regularly perform these upgrades across the Denver metro, including Lakewood. If your system needs more capacity or shows safety concerns, replacement is preferred over piecemeal repairs to meet code and reliability. Schedule an on-site evaluation to confirm the exact scope and final price.
