- 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.

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.
 Larry E. Mears, "Support clips for supporting electrical fixtures in a junction box", Patent number: 4679882
Filing date: Sep 17, 1985
Issue date: Jul 14, 1987, Description: Support clips for supporting the mounting brackets of an electrical fixture in a junction box are disclosed. The clips are formed from a single piece of sheet material and are adapted at one end to be crimped between the junction box and the junction box cover, and at the other end to engage and support the mounting brackets disposed on the ends of the fixture. In the case where the electrical fixture is a duplex receptacle, the clips serve to prevent the pivoting of the receptacle about a single center mounting screw during insertion of a plug into one of the receptacle outlets, and thereby prevent the mounting screw from loosening after repeated usage of the receptacle. retrieved 3/4/2013
 Pimentel, Demetrio (Atlanta, GA), patent application No. 10/058762, filed 01/30/2002, is described as follows:
A cover for an electrical outlet box which includes a plurality of bendable mounting clips constructed unitarily with the cover. In use, the mounting clips are oriented perpendicular to the outlet box cover and extend outwardly through an opening in a wall structure with the outer ends of the mounting clips then being bent outwardly into overlying engagement with the exterior of the wall surface in opposed relation to the outlet box cover thereby mounting the outlet box, and cover on the wall structure in alignment with the opening in the wall structure. The outlet box cover is mounted on the outlet box in a conventional manner and the mounting clips on the outlet box cover extend from the periphery of an opening in the cover for mounting electrical sockets, switches or the like in the outlet box in a conventional manner.
