Electrical fixes, with clear lines on what's DIY
Dead outlets, flickering lights, switches and smoke alarms. Some electrical work is simple and safe with the power off. Some isn't, and every guide here tells you plainly which side of that line you're on.
Where to start: When several outlets die at once, a tripped breaker or GFCI outlet is almost always the reason. Lights that flicker could be a loose bulb or a loose wire, and this guide helps you tell which. Replacing a light switch is a good first wiring job. And that 3 a.m. chirp? Here's how to stop it.

Common questions
What electrical work can a homeowner do?
Resetting breakers and GFCIs, changing bulbs, and swapping a like-for-like switch or outlet with the breaker off are common DIY jobs. New circuits, panel work and anything that smells hot or sparks are for a licensed electrician. Local rules vary, so check yours.
Why does my smoke alarm chirp even with a new battery?
It may need resetting, the battery may be in wrong, or the alarm may be past its 10-year life. The date is printed on the back.
