My kitchen fluorescent fixture has pulled lost from the ceiling and is dangling just by the electrical wires. It is an older home(25years) and the anchor bolts have pulled thru the drywall. I have tried to drill new holes but the drywall just keeps pulling out from the weight of the fixture. What type of repair person should I call because the drywall may need to be repaired also. Electrician, handyman, kitchen remodel shop??????
A handy man that knows how to patch drywall and some carpentry should be able to install blocking between the joists that the fixture can be screwed to but if you need someone that can match texture and finish you can get a drywall professional to do that part. You need to have an electrician evaluate the wire to make sure that the wire was not damaged by the fixture hanging by it he would also know how best to re hang the fixture.
Don't use plastic anchors. Instead, use "molly bolts" or expanding steel anchors that grip from BEHIND the drywall.
For Plan B, you could cut a short slot about 2" wide where it'd be hidden by the fixture, and slip a 3"-wide piece of plywood up through the slot. Turn it crosswise to the slot and screw through the drywall into it. Now you can screw your fixture to the plywood with drywall screws.
