How much does house rewiring cost per square foot?

Fix-it 24/7 Plumbing, Heating, Air & Electric does not price whole-home rewiring by the square foot; we provide a total project quote after an in-home evaluation. The biggest cost driver is the home’s existing electrical condition and how accessible the wiring is, not just square footage.

A full rewire often includes safety and code updates, new circuits for modern loads, and panel work when capacity is limited, so scope changes can shift price significantly. Our electricians focus on meeting or exceeding current Denver-area electrical codes, and we commonly bundle outlets, switches, lighting, and dedicated circuits as part of a complete upgrade. For homeowners in Littleton, our licensed team evaluates capacity and code needs first so the quote reflects the actual work. A practical insight: in older plaster homes, careful wire fishing to limit wall repair adds labor but preserves finishes.

If you’re comparing bids, look for these clear inclusions:

• Panel upgrade or replacement if needed
• Replacement of outdated wiring (e.g., knob-and-tube or aluminum)
• GFCI placements and any new dedicated circuits
• Lighting, outlet, and switch counts tied to the plan
