🧯 When to Call a Pro (Seriously)
There’s a line between handy and hazardous. Here’s where it’s safer—and legally smarter—to bring in a licensed electrician:
| Project | DIY? | Pro Required? | Why |
|---|---|---|---|
| Replacing old wiring | ❌ | ✅ | Risk of fire/code issues |
| Upgrading electrical panel | ❌ | ✅ | Requires permits and inspection |
| Adding new circuits or breakers | ❌ | ✅ | Must meet NEC standards |
| Knob-and-tube replacement | ❌ | ✅ | Outdated and unsafe |
| Electric vehicle charger install | ❌ | ✅ | Often requires 240v line and permit |
| Outdoor wiring (pools, sheds) | Maybe | ✅ | Moisture risks and local code |
⚠️ Reminder: Unpermitted or poorly installed electrical work can void insurance and reduce your home's resale value.
💸 Electrician Labor Rates in 2025
Depending on your region and scope, expect to pay:
- $85–$150/hour for licensed electricians
- $500–$1,500 for panel upgrades
- $1,000–$3,500 for full-home rewiring
- $300–$700 for 240v appliance or EV charger circuit

- Electrical for additions or renovations
Always check with your local permitting office. Estimero lets you tag items that require inspection or permits so nothing falls through the cracks.
