How much does it cost to rewire a house per square foot?

House rewiring is not priced by a reliable per‑square‑foot number; reputable electricians quote it by scope after an on‑site assessment. Most variation comes from the home’s existing wiring condition and how easily new cable can be fished through walls. A technician often bases pricing on circuits, device counts, protection upgrades, and panel capacity—not raw square footage. Focused circuit upgrades can be more cost‑effective when hazards are limited; if active knob‑and‑tube, aluminum branch circuits, or overheating are found, a full rewire becomes priority. In the Littleton area, many projects also include panel capacity improvements to support EVs, appliances, and smart gear. We handle permits and final inspections, and most standard full‑home rewires finish in about 5 to 10 business days.

Key factors that set the final price:

• Wiring type being replaced (knob‑and‑tube, cloth, aluminum)
• Access method: fishing vs opening walls and existing wall materials
• Required AFCI/GFCI and surge protection updates
• Panel upgrade or new dedicated circuits for large loads
