junction box

Hello all I fear a dispute with waterproofing contractor so need some advice I have two new water heaters in a duplex (one in each respective basement) -Model: Rheem 50gal Heaters (Purchased at Home Depot) -Electric heaters -Expansion Tanks -Dehumidifiers running 24/7 Heaters were...

I have a switch inside that controls one light inside by the basement sliding door (like a security thing to make it seem like someone is home). I am planning on getting rid of it and wiring a switch to a junction box outside to control some outdoor lights that we would install in the future...

I have a junction box that is screwed into the outside of a brick wall, but the two screws going into the brick are loose. Is there a preferred way to tighten this thing up (replace screws with bigger screws? some kind of adhesive behind the box to hold it to the brick?)? Thanks, Mitch
