Running wires through walls is fairly straightforward. This article provides the step-by-step method for you to follow.
1Decide where you want the wire to exit the wall (do not drill any holes yet)Ad
2Use a stud finder to make sure the wall has no cross beams between the exit location and the ceiling.
3Once you have determined the wall is clear from exit location to the ceiling, cut out a hole in the wall where the cable is to exit.
4Bring the wire into the wall. Either from the crawlspace or the attic. The crawlspace can be done with a flex bit (3-6ft drill bit sold at any hardware store or electrical supply house).
5Drill down through the hole in the wall and use the bit to pull the wire back up. Attic is a bit more difficult. You will need help locating the stud wall. Have someone tap lightly on the ceiling with a broom handle. You can feel the vibration with your hand to identify the exact stud wall location.
6Drill through the center of the 2x4 stud directly beside the tapping and drop the wire through the hole with a glow rod or some kind of weight to pull it down to the hole you cut in the wall.Ad
We could really use your help!
- You can use an insulation brace from the crawlspace to drill in the ceiling that will show you the location if you are working alone. Easily fixed (small hole)
- Try to identify markers such as light fixtures, ducts, electrical outlet lines, or anything you can use to locate your wall from the attic or crawlspace.
- Be careful when using a flex bit, once it breaks through, stop and tap the bit to see what you are going to hit next. Listen to the sound, may be brick piling, PVC water pipe, or an air conditioner. They each sound different.
- Always be sure of where you are drilling. If you are not sure it is the correct location, measure again.
