How much does it cost to rewire an old house completely?

The cost to completely rewire an old house is provided as an upfront, fixed price after an in‑home evaluation by Kanon Electric Inc. Pricing varies with the work required to bring your electrical system up to current safety standards. Our licensed, bonded, and insured electricians regularly complete full rewires around the Milton area. One thing we see often: planning a few clean access points before we start can streamline the project and minimize surprises. Financing options are available for larger projects.

What typically influences price:

• Total square footage and how many new circuits/devices are needed
• Existing wiring type and condition (for example, obsolete or damaged wiring)
• Access and finish level (open walls vs. fishing wires through finished spaces)
• Panel condition and related upgrades like sub‑panels, dedicated appliance circuits, or surge protection

"Grant and his crew did a great job rewiring our whole house. We have a 1951 rambler with a lot of old knob and tube wiring and Kanon Electric got our house up to code in just a couple weeks. Very impressed with their hard work, efficiency, and dedication!" — Amy W.
