Is it worth house rewiring an old house?

Rewiring an old house is usually worth it for safety, reliability, and bringing the electrical system up to current code. Most older homes still have legacy wiring (like knob‑and‑tube or cloth-insulated cable) that wasn’t built for today’s appliance loads or grounded protection. A full rewire also lets you add capacity for kitchens, home offices, EV chargers, and smart tech, often alongside a panel upgrade with proper permits and inspections handled. Our team has deep experience preserving finishes while updating historic New England homes, and you receive final testing and written documentation when the work is complete. For affordability, every rewiring job includes a $0 written estimate before work begins.

Consider a full rewire when you notice:

• Knob-and-tube, BX, or cloth-insulated wiring in walls or attics
• Plans for EV charging, kitchen remodels, or other dedicated circuits
• Panel capacity that can’t support added appliances or smart devices
• Need for documented, code-compliant wiring for a sale or renovation

Have a licensed electrician perform a full inspection and load test before adding or replacing circuits.
