How much does house rewiring cost per square foot?

House rewiring cost per square foot varies widely and is only confirmed after an in‑home assessment. The biggest driver is labor access (how easily wiring can be fished through walls and ceilings), followed by scope and code upgrades needed. We provide upfront, flat‑rate written estimates rather than rough phone quotes. We regularly rewire older homes in Maplewood, NJ, and handle required New Jersey permits and inspections for code compliance.

Key factors that change price:

• Size of the home and number of circuits to replace
• Wall/ceiling access (plaster, lath, insulation, attics, crawlspaces)
• Panel or service upgrade needs to support modern loads
• Safety/code items like GFCI/AFCI protection, grounding, and surge protection

Final pricing is verified after a licensed electrician inspects the existing wiring, panel capacity, and access points.
