On 2018-11-08 by Steve - exterior brick veneer wall - porch light damaged during a storm

I have a porch light that was damaged during a storm. Fortunately the light was undamaged, but the junction box that's in the brick broke in half where the screw holes are.

To me, it looks as if I need to replace the junction box. My question is, "How"? The box has mortar all around it and obviously won't just pull out. Just not sure how to go about doing this myself. Any input would be appreciated.

In the U.K. an inventor has produced MBM - Metal Box Mender - about which we have written at METAL ELECTRICAL BOX SCREW REPAIR

A PVC electrical box may be amenable to a similar repair - for now - until our article appears - see

Often you can drill out the existing screw opening and use a sheet metal screw PROVIDED you clip off and file smooth the screw and make sure that in addition it's no longer than necessary.

Watch out: You don't want to pierce an electrical wire in the box or you'll be sorry.

See ELECTRICAL PANEL COVER SCREWS for an example of what can go wrong.

An electrician or other expert looking at your hookup might see other safety hazards that need attention.

If there were no problem other than a stripped receptacle securing screw the electrician would more likely install an oversized screw (watch out for / don't use pointed sheet metal crews that cut into wiring) rather than face the cost and trouble of replacing the whole electrical box.

I'm switching out a dryer cord from four-prong to three, and it looks like the screw holding the black wire was stripped out by whoever installed the first cord. I'm not experienced with electrical work, but I don't want to leave this loose.

I can screw it in, but the slightest amount of pressure pops it free again. Any advice on how to secure it? Longer screw? Should I just head for the hardware store? Any help will be appreciated. Dryer's out of warranty.

Thanks for the tips Mike.

If the stripped outlet box is made of metal, you can try using a tap tool. If the existing screw is broken off in the metal box, you can drive the screw through using an awl and hammer (the screw is softer metal than the box).
If the outlet box is made of plastic, you can use a "G-Clip" to make the repair.

The clip pushes onto the damaged box and accepts the 6-32 screw. check out g-clip us on line.
