Know When to Call a Pro
The skill isn't only knowing what you can fix — it's knowing what you shouldn't. Some jobs are dangerous, illegal without a permit, or both.
Confidence with a screwdriver is good right up until it walks you into a job that can burn down a house or flood a floor.
Electrician-only: anything inside the panel, new circuits, aluminum or scorched wiring. Gas of any kind — lines, appliances, a rotten-egg smell — is a stop-and-leave, then call from outside. Plumber: water heaters, soldering pipes, main lines. Roof, structural, and dangerous height are their own no.
Permits exist for these reasons, and codes vary by where you live. None of this shrinks what you can do — it sharpens it.
Stop and dial the pro
Treat the hard boundaries as absolute
Some work is off-limits no matter how confident you feel. Make these an automatic hand-off to a licensed pro.
- The breaker panel, service, or any new circuit
- Anything gas, and any gas smell — leave, then call
- Water heaters, soldered pipes, main lines
Read the warning signs mid-job
Even on an allowed task, back out the moment you meet aluminum wiring, scorch marks, cloth insulation, a smell of burning, or hidden damage. Discovering you're out of your depth is a reason to stop, not push on.
Respect permits and local code
If a job legally needs a permit or inspection where you live, it's regulated for a reason. When in any doubt about scope, safety, or code, call a licensed pro before you start.
The most expensive repair is the one you should have handed off. Knowing your limit is a skill.
