Wiring without opening the walls?

get remodel or cut in boxes that is the only hole you need to cut in the wall. you cut the hole for the box then you drill a tiny hole in front of the wall with a long 1/8 drill bit , I sometimes use a piece of coat hanger. i find it in the basement to identify where to drill my hole for the wire, use a fish tape or a chain and telescoping magnet drop the chain down the wall and catch it in the basement with the magnet.

I also use a long flex bit its 4' long with a 1/2 inch drill on the end.

I don't think you can. You can try running the largest part of the cable run either in the basement/crawlspace or in the attic and then drill through either the top or bottoms of the walls and then poke the cables out wherever on that wall you need to.

If you want to run it across any interior or exterior wall you will have to deal with any vertical framing members like 2x4s which are spaced around 16inches on center though I have seen different spacing on interior walls and you cant do that without opening the walls.

If you are totally unwilling to make holes here and there you should probably consider wireless internet etc. Just make sure you read up on the security setup so that you can help prevent unauthorized access to your network.

Do like the electrician said, cut in the boxes after dropping the wire in through the top plate of the wall (access from the attic). Have someone yank the wire back an forth, thumping the wall while you listen or feel for it to make sure you have the right stud cavity.

this isn't expensive. I had an electrician rewire the complete kitchen in a job we are doing for around $400 bucks. The old wires were ran through the cabinet fur down or soffit and were in the way.

could be much less stressful and safer to easily purchase a quick potential strip with a outfitted in toggle swap and plug the unit into that for the period of a handy adjoining spot. In-line swap splicing on potential cords has extremely some capacity for issues and can be a code violation in some situations. i've got additionally chanced on the swap assemblies tend to placed on out quicker than i could like them to. Having a switched potential strip is definitely available. The toggle is frequently illuminated so which you will tell at a glance no remember if it is on or off and you will possibly be able to get one with a surge suppressor as properly to added take care of your shreader. I even have extremely some gadgets or maybe home equipment in my domicile plugged into potential strips.

Run the wire through duct work if you have forced air heating.

Otherwise, your only choices is to put holes in the walls, or run the wires on the outside of the walls (they make wire runner/covers for that)
