Wiring & Rewiring in New Orleans, Louisiana

Rewiring is one of the most consequential home electrical projects, and in New Orleans it is also one of the most common. The city's housing stock includes large numbers of pre-1940 homes still operating with original knob-and-tube wiring, mid-century homes with aluminum branch circuits, and a wide range of homes with electrical systems that have been modified, patched, and added to over many decades. Insurance companies are increasingly requiring remediation of these systems before issuing or renewing policies, which has made rewiring a frequent service request in Orleans Parish.

What rewiring costs in New Orleans

Whole-home rewiring in New Orleans runs $8,500 to $25,000+ for a typical 1,500-2,500 sq ft home, with significant variation based on home age, accessibility, and scope. Specific cost drivers: square footage, number of circuits added, panel upgrade requirements, plaster vs. drywall walls (plaster is more difficult to fish wires through), and the level of finish restoration required after the work.

Partial rewiring — for example, addressing only the kitchen and bathroom circuits, or only replacing aluminum branch wiring — runs $3,500 to $10,000 depending on scope. Whole-home rewiring with panel upgrade and modern AFCI/GFCI protection throughout will be at the higher end of the range.

Most New Orleans rewiring projects also require Orleans Parish permits and inspections. Historic district homes additionally require Vieux Carré Commission or Historic District Landmarks Commission review for any visible exterior electrical work.

When rewiring is necessary

Four conditions typically push a New Orleans home toward rewiring. First, knob-and-tube wiring throughout — most insurance companies now require remediation before issuing or renewing policies. Second, aluminum branch wiring (1960s-70s installations) — same insurance pressure applies. Third, undersized electrical service that cannot safely support modern HVAC, appliance, and electronics loads. Fourth, evidence of unsafe modifications, fire damage to wiring, or significant water damage to electrical components.

A partial rewire is sometimes the right answer, particularly for owners who are budget-constrained or planning to address electrical work in stages. But a partial rewire that leaves problematic systems in place may not satisfy insurance requirements, so coordination with your insurance carrier matters.

What the rewiring process looks like

A typical whole-home rewire in New Orleans takes 5-15 working days depending on home size and complexity. The work involves: opening walls and ceilings to access existing wiring (more invasive in plaster construction than drywall), running new wiring, installing modern outlets, switches, and protection devices, upgrading the service panel, removing old wiring where accessible, and finish work to restore opened surfaces.

Living in a home during rewiring is possible but disruptive. Power will be off in sections of the home during work, walls will be opened, and dust and debris are unavoidable. Many homeowners arrange to be elsewhere for at least the most invasive portion of the work.

Choosing a rewiring contractor

Look for master electricians with documented experience on historic homes if your home is pre-1940. Plaster walls and historic millwork require gentler work than drywall construction, and inexperienced crews can do thousands of dollars in unnecessary finish damage. Ask for references on similar-vintage homes specifically. Check the electrician's current Louisiana license yourself before rewiring work begins — electricians that complete our verification process carry a Verified badge.
