How much does it cost to rewire a whole house professionally?

Professional whole-house rewiring costs vary widely and are confirmed only after an on-site assessment by a licensed electrician. The biggest price driver is scope of work, followed by labor, equipment, and materials needed to bring your system up to code. Rewiring may also involve panel upgrades and adding modern safety features, which can change the total. In older homes, tight access behind walls or ceilings can add labor hours faster than most people expect. Our electricians regularly deliver code-compliant rewiring across the Denver area with a safety-first approach and transparent, flat-rate pricing.

Key factors that affect price:

• Home size and the number of circuits/outlets to replace
• Access conditions (attic, crawlspace) and any wall or ceiling restoration
• Panel capacity upgrades or added dedicated circuits for larger appliances
• Code-required safety devices like GFCI protection and new devices or fixtures
