Why does my ceiling fan wobble, and is it dangerous?
Short answer
Fan wobble is almost always caused by unbalanced blades, loose blade screws, or a warped blade — not a mounting problem. Tighten every blade screw, use the balancing kit that came with the fan, and check for a bent blade. A fan on a properly rated brace won't fall, but chronic wobble will kill the motor bearings in a few years.
Fix the easy stuff first
Kill power, remove the light bulbs, and torque every blade screw with a screwdriver — don't overtighten. Then check each blade at the same reference point (a piece of tape on the ceiling) to spot a warped or bent blade.
Use the balancing kit
Every quality fan ships with a balancing kit: adhesive weights and a plastic clip. Clip it to one blade at a time; find the blade where wobble decreases most; move a weight to that blade. Ten minutes and it's noticeably smoother.
When to just replace the fan
If the blades are warped from heat or humidity (common in bathrooms with a fan-light combo) or the motor whines at low speed, you're past a fix. A quality replacement is $150–$300; installation is another $175–$325.
What we see on Home Health Assessments
About 38% of homes built before 2005 are missing GFCI protection somewhere the current NEC requires it (kitchens, baths, garages, exterior).
Caught early on assessment: $85–$240 · Left until failure: $300–$1,500
