That's an electrical junction box. Likely for a ceiling light, but could also be for a ceiling fan, smoke detector, or anything else mounted on the ceiling that needs power attached.

That is a 4" deep Octagon Box. It is a standard electrical junction box for mounting lights and other ceilingey things. (not a fan; that takes a reinforced box). Note the single Romex (NM-B) cable entering it. The person is applying a junction box extension ring. They're modestly expensive, especially since, as an obscure item, the big-box stores will ...

If you have wires/cables that run across the top of the attic floor joists, you could build up the joist with ripped 2x4's that would provide another 1-1/2 inch clearance above the joists for the wires. You would have to provide a gap between the added sections of wood to provide a channel for the wires to lay in. Or lay 2x4's flat perpendicular to the ...

"Because we are installing the res' channel" is parenthetical, "by half an inch" is talking about the ceiling, not the channel. "We are going to be lowering the ceiling (because we are installing the res' channel) by half an inch" "We are going to be lowering the ceiling by half an inch"

Go for the easiest option. It isn't worth trying to maximize material usage or trying to get a few less seams. Even 1/2" drywall sheets are heavy. I'd opt for 4x8 especially if you aren't renting a drywall lift. Even if you are using a lift you still have to move the sheets around. A couple more tape seems just isn't a big deal.

Personally, I'd stop the crown molding at each end of the fireplace with some compound miter end caps unless you're really good with a coping saw. If you run it a couple inches off the ceiling , your recessed lights will leave a shadow at the top of the fireplace. Just my humble opinion.

I live in the Pacific Northwest where ceiling cable heat used to be very popular. When I have found heating problems with not getting hot enough where it did heat properly in the past it has always been the thermostat with 1 exception. The 1 exception was a parallel cable set in a large room where a swagger lamp toggle bolt was drilled through 1 of the ...

Many ceiling textures are created by putting some mud on the ceiling with a perpendicular motion, then swiping sideways with a trowel ("knock down"). I see some parts of your texture that look like this might be what happened. Other parts of the texture have wide valleys with sharp narrow ridges. Those look to me like they were done very wet or runny. Maybe ...

The video narrator misused the term, it has no proper english meaning the way he used it. You are correct in that the depth of the channel itself is only determined by the choice of channel, but an installer could shim a channel to make it drop lower than the manufactured dimension (depth). It would have been more appropriate had the narrator said ...

That light fixture was too close to the wall anyway. Patch the old hole with a self-sticking drywall patch, then mount a new box to the joist about 8" further away from the wall. There are boxes that can be screwed right into the joist from below the ceiling (look for Madison Electric Products Fan and Fixture 1-Gang Gray Polycarbonate New Work/Old Work ...
