How much does it cost to upgrade a fuse box to a breaker panel?

Costs vary by home and are confirmed after an on-site inspection. Price depends on panel size (for example, upgrading 100A to 150A/200A), wiring condition, grounding, surge protection, and permit/inspection needs. Most upgrades take 4–8 hours. In Carrollton and across DFW, we perform load calculations, handle permits and inspections, and coordinate with Oncor when needed. Select equipment may qualify for our lifetime parts & labor warranty with annual licensed maintenance. Financing is available with approved credit. <br/> Updated: 2025-12-31 00:00:00 <br/> Need help in Carrollton, TX? Call (214) 612-0133 or book online.
