How much does it cost to rewire a full house safely?

A safe full-house rewiring is priced only after an on-site assessment because cost depends on home size, access conditions, code upgrades, and permit requirements. The biggest driver is how much new wiring and protection your system needs to meet current electrical code, sometimes alongside panel improvements. We provide upfront pricing once the evaluation is complete, and financing is available for larger electrical projects. Our electricians routinely complete code-compliant upgrades across the Denver metro, including homes near Centennial.

Key factors that move pricing up or down:

• Square footage and number of branch circuits to replace
• Need for panel upgrades, AFCI/GFCI protection, or surge protection
• Difficulty fishing new cable through finished walls, attics, or crawlspaces
• Remediation of aluminum or knob-and-tube wiring, plus any wall/ceiling patching

If you suspect unsafe wiring, turn off the affected breaker and schedule an in-home evaluation.
