What you need is a ceiling medallion. That's a fancy name for "a circular thing you stick on the ceiling to look nice and cover a hole". A lot of them are designed to actually have a lamp hang from them, but there are some with a big hole in the middle which is exactly what you need here. There are simple ones: and fancier ones: Some are white or metallic ...

You need a conduit. For that matter you would need a conduit if running them inside the ceiling space.

I'd be looking to cut around the perimeter of the box, isolating it from the ceiling and then. go to work on the steel once the vibrations from cutting it will not be transferred to the ceiling An angle grinder will make short work of steel, but does produce lots of red-hot sparks that travel quite a distance before cooling. A hack-saw is slower, and can ...

Individual wires of any kind require a conduit, raceway, gutter, etc. etc. Regardless, however you plan to mount those wires (draped from hooks?) would also be illegal if you were using cable instead of wire. There is no way to do this in the way you imagine. Homes need utility spaces. When people cashier those spaces to create additional finished/...

There are many approaches. One of the least labor-intensive (but folks who have not gone down the route of removing wallpaper, etc. almost never believe it) is to apply a new layer of drywall (thinnest you can source) over the walls & ceiling you don't like the paper/texture on. That spares you from hours of steaming wall paper and fighting with the ...

Do not cut the rebar in the concrete ceiling slab. Rebar is placed in concrete slabs (and beams) for tension. Cutting the rebar eliminates the resistance to tensile stress and could cause immediate failure (collapse of the slab).

What that needs is a good scrubbing with warm soapy water. If the paint comes off because it is old or because it is no longer durable enough to survive a good scrubbing... then it needed repainting anyway. Use a high quality gloss or semi-gloss paint if you do it.

is it new construction? Houses are going to settle and those drywall joints sometimes bulge out a little bit. Even if it's not new construction, houses will continue to shift as they age, especially with seasonal changes in temperature and humidity levels. The drywall contractor that hung those sheets should have left a small gap between them, which was ...

This is normal, they are just the seams between the drywall panels. Even the best drywall installers can't make a perfectly level joint. But, a skilled installer will feather them so they are not noticeable under most circumstances. Based on the shadow, your picture has oblique (low-angle) lighting, it will accentuate the seams. If you have a long wall, put ...

Green is indeed ground pretty much everywhere except old work in the Soviet Bloc. You need to attach the new light the same way the old light was attached. It is likely of the 4 wires from the wall, two of them were attached to each other and not to the lamp. Reconnect those same ones the same way. In wiring, colors don't mean a whole lot, becuase ...

The streaks are actually strips of "clean" or at least cleaner than the surroundings. Unless adjacent to a kitchen, or the room used by smokers the dirt is unlikely to have an oil component. Try the following: Hot water (as hot as you can stand with kitchen gloves on) and laundry detergent. This is generally good for the mix of dust and water that is ...

If you have to do this from below then you need to remove a large section of drywall such that you can secure the metal housing for the fan to supports. Once you need to cut a large section of drywall you might as well mark the joists and cut back to 1/2 the width of the closest joist and remove from one joist to the other, for the other dimension whatever ...

White distilled vinegar works great. Just put it in a spray bottle and spray on to the moldy surface. Wait an hour and then wipe down surface with water. I used to use bleach but it only really works on non porous surfaces. Does your bathroom vent well? Try to determine the cause of the mold and fix it. Also, don't let it build up until the next ...

If you don't think that a plain color medallion will look good, I would consider a thin (~1/8 - ~3/16) stainless steel disk about 7" inches in diameter (not too expensive on ebay). Cut three holes to match. Polish with brasso and/or use an appropriate grit sandpaper to match the finish on your canopy. Hopefully, the holes can be fairly small. If you need to ...
