Why older homes need rewiring

Homes built before 1970 often have knob-and-tube or early Romex wiring that can't handle modern electrical loads. Insurance companies may refuse coverage or charge higher premiums for outdated wiring.

What to expect during the project

The electrician maps all existing circuits, runs new wire through walls and attic/crawlspace, installs a new panel, and connects all outlets and switches. Expect some wall openings that will need patching.
