I've got a light on either side of the front door. I noticed the other day that they seemed a little crooked. Went to adjust them, and noticed that they've both detached the box from whatever it was attached to and are now hanging with the box inside the hole in the brick.
I don't see any screws or anything in the back of the box, so assume they were just set in the brick with mortar and have pulled out over the years from wind, rain, kids etc.
What's the best way to fix these boxes so that they're secure and attached to the house?
If it were me, and there is no obvious way to secure them with screws to structure, I would use some form of adhesive to re-attach to the brick. Epoxy is my first thought. My only hesitancy is whether this meets code with regards to fire protection.
