I'm sorry to say, and hate to criticize other's work, but those screws are not driven properly. The screws need to be driven with a sheetrock screw gun or a dimpler bit in a regular screw gun. The screws need to be slightly counter sunk with an indented dimple around the screw head into the sheetrock to hold some joint compound. The screws should not break ...

The white marks are joint compound (aka "drywall mud") - kind of like plaster. The stripes are where separate sheets of drywall are joined with tape and mud and the little splotches are where screw holes have been covered over with mud. Those actually are good places to install your storage rack because they indicate the locations of the lumber framing that ...

Usually at least one of the "claws" is spring-loaded, and can be pulled straight out to release the glass.

Ideally this should be screwed/anchored into a joist for maximum support. However, if you really want to use a drywall anchor, you should use a toggle bolt or a ceiling anchor. Instead of just screwing into the wall, these expand to several times their size which gives you a good hold, especially when the force is pulling directly down. 10lbs might be ...

Terminology-wise those look like bolts. Removing-wise, look in the attic above the room for bolt-heads, first. If they are not though the joist, they are probably a "lag/machine combination", and you put two nuts on, tightened against each other, then use a wrench on the upper one to back them out. Putting them in is the same, but you put the wrench on the ...

There is no problem with installing junction boxes above a suspended ceiling, as long as the box is less than 100 in.³ and securely fastened. National Electrical Code has this to say... National Electrical Code 2014 Chapter 3 Wiring Methods and Materials Article 314 Outlet, Device, Pull, and Junction Boxes; Conduit Bodies; Fittings; and ...

It may not be termites but it looks likes some kind of insect infestation. I would contact either the building owner or a local pest exterminator. What ever the tunnels are made of is likely building material. I would recommend doing this quickly before there is structural damage to the building.

There's two principles to soundproofing that actually work: Isolation and Absorption. The trick is figuring out the right way to implement them. Be careful of anything that doesn't follow these two principles. The Absorption principle is how acoustic ceiling tiles and carpets work: They absorb the sounds as they pass through the material, or they keep the ...

Nail holes in a joist wouldn't concern me unless it affected a significant proportion of the joist. You can safely drill a hole 1/3 of the width of the joist in the middle for running wiring. Cracking or sagging that is allowing the home to go out of level/plumb is a concern. It's best to get a structural engineer to evaluate this problem. The standard ...

The cable with the white wire that's connected to the two black wires is a switch loop: Normally wires with white insulation are used only for neutrals, but code makes an exception to allow for use of the white wire in a cable used as a switch loop as a hot rather than a neutral. If you'll look closely in the drawing, the whites used as hots are wrapped ...

I assume you mean the roof is exposed to the sun...and that in turn is heating your ceiling? If so, options: make sure the roof is reflective (white/metallic) rather than a dark color (which absorbs heat) make sure the roof is insulated If the roof can support a green/planted roof, consider that. plant trees to shade the roof (obviously may take a few ...

Utility Knife Position a 2'- 4' level (or other straight edge) along the line you'd like to cut. With the straight edge in place, gently draw the utility knife along the line. You don't have to press too hard, just enough to cut through the paper on the face of the drywall. Draw the utility knife repeatedly through the groove you scored in the previous step....

I have the same one...the definitive answer is as Grant says. One of the clips pulls out enough to remove glass! No screws or screwdrivers needed.

From what I see in your pics, you have a plaster ceiling that is failed. Usually water is the culprit for delaminating the scratch from the finish coats. You have two options to repair this. First option is to remove all loose plaster down to the lathe and replace it with new plaster. This is not as easy as it may sound. Working with real plaster takes ...

The overkill direction (which is actually appropriate for some circumstances, such as a ceiling that needs to hold up a lot of insulation, as for an attic above) is to run 1x3 strapping opposite to the joists. An advantage in the application I mention is that this strapping can be on 12 inch spacing, so the drywall can be attached with a screw every foot, ...

I would assume it's because you have plaster ceilings that use metal lath.

Yes, you should install covers on the boxes. You should be able to pick up covers at the local hardware or big box, fairly cheap. Just make sure you measure all the boxes, and note their shape, before heading to the store. If the mounting screws are not in the boxes, you'll also have to pick up some of those. National Electrical Code 2014 Chapter 3 ...

The type of bolt that you show and the size comparison that you demonstrate in the second photo would indicate that these were installed for ceiling hooks of the type pictured below: Indeed if the ones in your ceiling seem solidly placed then the hook was installed using the ceiling joist type of bolt/screw as shown in the right part of the picture. The ...

A suspended ceiling may help a bit. They are not designed to be insulators, but it will keep the hot air lower. Right now in the room, you should be able to feel a gradient where it gets warmer. I suspect that more or less you'll have the same gradient, but moved down by roughly the same amount you move down the ceiling: eg if you put a drop ceiling at 8', ...

I find that it's best to attach 1x3 furring strips across the joists. It's worth the extra cost. The 1x3 will give you 1.25 inches of screwing space, so you don't have to be quite as accurate with your cuts. Glue is not needed, but will reduce screw pops by making the assembly more 'solid'. I always use adhesive when I can (when there is no vapor barrier ...

Here's my take on drywall vs skim vs full update. Skimcoat Skim coating over the plaster that is already cracking would not be a good idea. Even if you use a harder more durable mud or plaster, it will still most likely crack because of the age of your house, and the fact that your walls are already cracking (and will probably continue to do so). The ...

The easiest option would be to run a new cable directly from the switch, up to the ceiling fixture. You'll want to either install a larger box and a new switch, or a double switch, so the light can be controlled independently. If you're working in a home constructed of solid wood framing, you should be able to run the new cable fairly easily. Since you didn'...

Getting rid of this texture will be a lot of work. I would recommend that you leave it there unless you absolutely must get rid of it. The ceiling appears to be painted, which means that the texture cannot simply be sanded off. I actually have a similar texture applied to some of the walls in my home. The only way to eliminate it besides either tearing down ...

With option 2 you have twice as much seam length running down the center of ceiling joists. This can be a real pain to keep everything aligned, especially when you have roof braces, overhead door brackets, and other structures holding the truss members rigidly in place. Also, some brands of drywall aren't designed to resist sag parallel to the mounting ...

You don't have joists or rafters. You have engineered roof trusses. The bottom chords are 2x4 because that's all that's required for your scenario. They don't span the ceiling themselves. They're part of a rigid structure that's supported by both the top chords and the diagonal truss members. This is typical and has been standard practice since the 1970s ...

This is what an unpainted surface looks like. Those white marks are joint/drywall compound and under them are screws holding the drywall to the joists. The long white lines are the same thing except on a junction between two sheets of drywall. So there are screws and a seam under them. You can install a rack along the white marks but not directly in the ...

If you dont want to run a new pipe you will need specific insulation Notice that this insulation has a shiny outside layer. This acts as a reflection for heat, and usually has a black/dark side on the inside. The foam/glass wool used to wrap the pipe needs not be anything special, but I am sure there are special ones that locks out heat better.. instead of ...

Drywall is easy to patch without having to cut it back to expose a joist. Here's how: Cut a piece of thin wood to a length that is a couple inches longer than your hole. A paint paddle or the thick side of a wooden shim works well for this, but any scrap piece of wood will do. Drill a screw partially into the middle of your scrap piece of wood. ...

You can install a shallow 6" can made for 2x6 construction. Halo H27ICAT is the 6" you can use. Lots of manufacturers make these shallow cans. You can use regular incandescent, fluorescent and LED lamps and have a large selection of trims. The only drawback is you can't use taller lamps or they might stick out the bottom. The most common is the ...

Generally speaking, a room with a light-colored ceiling will appear taller than a room with a dark-colored ceiling. However, in a really small space painted in a darker color, painting the ceiling the same color will make the border between wall and ceiling disappear, making it more difficult to gauge the ceiling height by sight. A related technique for ...
