What Does It Cost to Rewire an Old House?

1. Replace or Clean Your Air Filters

If you own an older home, especially one built before the 1960s, there's a good chance the wiring behind your walls wasn't built for how homes are actually used today. Rewiring is one of those projects homeowners often put off until something forces the issue, a failed inspection, a flickering light that won't go away, or an insurance company that won't renew coverage without an update. Here's what actually goes into the cost.

Why Older Homes Often Need a Full Rewire

Many older homes still have knob-and-tube wiring or early aluminum wiring, neither of which was designed to handle the electrical load of a modern household with air conditioning, computers, and a kitchen full of appliances. In most cases, this isn't something that can be partially upgraded, it requires a full rewire to bring the home up to current code and safely support today's electrical demand. 

What Drives the Cost of a Rewire

A few factors matter more than square footage alone when it comes to pricing a rewiring project.

Home Size and Layout

Larger homes, and homes with more complex layouts, simply require more wire, more outlets, and more labor hours to complete.

Wall and Ceiling Access

Rewiring is significantly less invasive, and less expensive, in a home with an accessible attic and basement than in a home where walls need to be opened up to run new lines.

Contact MS Contracting & Electric for an assessment of how accessible your home's wiring actually is.

Panel Age and Capacity

If your electrical panel is also outdated or undersized, a full rewire is often paired with a panel upgrade, which adds to the project but is usually necessary regardless, since old wiring is rarely paired with a modern panel. Schedule an electrical evaluation today.

Number of Outlets and Fixtures

Older homes were often built with far fewer outlets than we rely on now. Adding outlets and updating fixtures during a rewire is common, and each addition adds incrementally to the scope.

What a Rewire Actually Involves

A full home rewire typically includes:

• Removing old wiring, including any knob-and-tube or aluminum wiring

• Running new, code-compliant wiring throughout the home

• Installing or updating outlets, switches, and fixtures

• Coordinating with a panel upgrade if needed

• Permitting and inspection to confirm the work meets code

Each of these steps requires a licensed electrician, both for safety and because most towns require permits and inspections for this scope of work.

Why Rewiring Costs More Than Homeowners Expect

Rewiring is often more expensive than homeowners anticipate because the wiring itself is only part of the job. Walls, ceilings, and sometimes flooring need to be opened up and patched back afterward, and that finish work, drywall repair, paint touch-ups, adds real cost beyond the electrical labor itself. 

Can You Rewire in Phases?

In some cases, yes. Homeowners sometimes rewire room by room or floor by floor to spread out cost over time, particularly if the home isn't in active renovation. This isn't always the most cost-efficient approach long-term, since opening walls twice is more expensive than once, but it can make the project more manageable for some budgets.

Signs Your Home May Need Rewiring

A few signs it's worth having your wiring evaluated:

• Frequent tripped breakers or flickering lights

• Warm or discolored outlet covers

• A fuse box instead of a modern breaker panel

• Difficulty getting homeowners insurance due to old wiring

Any of these are worth a professional look rather than waiting for a bigger problem to develop. Schedule an electrical evaluation today.
