How much does it cost to rewire a house in Connecticut?

Whole-house rewiring in CT typically runs $8,000 to $25,000 or more, roughly $4 to $9 per square foot. A small 1,000 to 1,500 sq ft home runs $8,000 to $15,000; an average 2,000 sq ft home $12,000 to $22,000; large or hard-access homes $20,000 to $35,000+. Most quotes include a new 200-amp panel, the permit, and inspection; plaster and drywall patching may be separate.

What drives the price of a rewire?

Square footage and number of circuits, access (open framing during a renovation is far cheaper than fishing wire through finished plaster walls), whether knob-and-tube or aluminum has to be removed, whether a panel upgrade is included, how much plaster/drywall repair is needed, and whether the home is occupied or vacant during the work.

Does rewiring include a new electrical panel?

Usually yes. A full rewire is almost always paired with a new 200-amp panel because the old service cannot safely carry modern circuits, and doing both on one permit and one Eversource visit is cheaper than separate jobs. We quote the panel as part of the rewire so the all-in number is clear.

How long does a whole-house rewire take?

A typical 2,000 sq ft home takes about 1 to 2 weeks depending on access and whether it is occupied. We stage the work room by room so the home keeps power overnight, swap the panel mid-project, and schedule the inspection at the end.

Whole-House Rewiring Cost in Connecticut (2026)

Q: Can you rewire a house without tearing up the walls?

Largely, yes. Experienced electricians fish new wire through existing wall cavities, attics, basements, and stud bays to minimize cuts. Some access holes are unavoidable, but a careful rewire on an occupied home preserves most finishes; we plan the routing to keep plaster and millwork intact.

Rewiring a house in Connecticut runs $8,000–$25,000+ — roughly $4–$9 per square foot — depending on size, access, and whether old knob-and-tube has to come out. Most rewires include a new 200-amp panel, permit, and inspection. Here’s the honest breakdown, written by Tyler Faye, a CT-licensed master electrician who rewires older homes across Tolland and Hartford counties.

Rewiring Cost at a Glance

Small home (1,000–1,500 sq ft)

$8,000 – $15,000

Cape, ranch, or small colonial. Lower circuit count; cost driven mostly by access and whether knob-and-tube is involved.

Average home (1,500–2,500 sq ft)

$12,000 – $22,000

The most common CT rewire. Includes a new 200-amp panel, modern circuits, grounded outlets, and code-required AFCI/GFCI.

Large / complex (2,500+ sq ft)

$20,000 – $35,000+

More circuits, multiple floors, plaster walls, and hard access push both labor and patching higher.

Partial / targeted rewire

$3,000 – $8,000

Replacing just the knob-and-tube or one problem area rather than the whole home — common for insurance compliance.

Installed prices in Connecticut, typically including a new 200-amp panel, permit, and inspection. Plaster and drywall patching may be quoted separately depending on access.

What Drives the Price

Square footage & circuits: More floor area means more circuits, devices, and wire — the single biggest cost driver.
Access: Open framing during a renovation is far cheaper than fishing wire through finished plaster. Occupied homes with finished walls cost more than gutted or vacant ones.
Knob-and-tube or aluminum: Removing old knob-and-tube or addressing aluminum branch wiring adds scope and care.
Panel upgrade included: Most rewires pair with a new 200-amp panel; bundling it on one permit is cheaper than two jobs.
Plaster/drywall repair: Patching access holes in plaster walls and historic finishes adds labor — sometimes a separate line.
Occupied vs. vacant: Working around a family living in the home (staging room by room, keeping power overnight) takes longer than an empty house.

CT-Specific Considerations

Older housing stock

Eastern CT has a lot of pre-1940 housing — mill-era multi-families, farmhouses, and lake cottages — where knob-and-tube, fuse boxes, and ungrounded outlets are common. A rewire is the moment all of that comes up to current NEC code. See our whole-home rewiring and knob-and-tube replacement services.

Insurance & permits

Many rewires are driven by an insurance carrier flagging knob-and-tube at renewal. We pull the town permit, pass inspection, and provide the documentation carriers require. A rewire almost always includes a panel upgrade — see the panel upgrade cost guide for that portion.

Rewiring Cost FAQ

How much does it cost to rewire a 2,000 sq ft house in CT?+

Most 2,000 sq ft CT homes run $12,000–$22,000 to rewire, including a new 200-amp panel, permit, and inspection. Access and knob-and-tube removal are the main swing factors.

Does a rewire include a new panel?+

Usually yes — the old service cannot safely carry modern circuits, so we bundle a 200-amp panel upgrade on the same permit and Eversource visit.

Can you rewire without gutting the house?+

Largely, yes. We fish new wire through wall cavities, attics, and basements to minimize cuts. Some access holes are unavoidable, but a careful rewire keeps most plaster and millwork intact.

My insurance company flagged knob-and-tube. What now?+

That is one of the most common reasons we rewire. We remove the knob-and-tube, bring everything to code, and give you the documentation the carrier needs. See knob-and-tube replacement.

How long does it take?+

About 1–2 weeks for a typical 2,000 sq ft home, staged room by room so the house keeps power overnight, with the inspection at the end.
