The questions I am about to ask are general questions about pulling in new cable (whether it be electrical, coax, or data) through existing walls in a two-story home. The situation is I am attempting to run/pull some RG-6 cable (satellite dish hookup) from the attic to some second floor room connections and also down to the first floor living room area. The questions I have are these:

1)Are there any suggestions as to how to fish a pull line in existing drywall walls that have 2 x 4’s halfway up the wall (either used for either fire breaks or drywall nailing points, I’m not sure) all around the room? I would like to avoid any drywall work/repair, but if I have to go that route, I guess I’ll have to.

2)Are there any electrical wiring “gotchas” that I should be aware of?

3)A TV antenna was installed in the attic (city ordinance or building code requirements) when the house was first built 25 years ago. It has a coax cable (RG-56) that runs down to the first floor inside the walls. Are these cables usually tacked to studs like electrical wiring usually is or are they strung unsecured within the walls? I am thinking of using this as a pull line, if possible, to get down to the first floor.

As with any DIY project, good common sense is always something to go by, however, anyone out there who possesses more common sense and experience on the subject than I, and who may have some suggestions is someone I am eager to hear from.

Thankx!!!

I don't have any detailed answers.

But you can drill through the blocking using either long bits or bits with extensions.

Look the articles at this link for some ideas.

Most low voltage cables are not secured to the framing. Of course, it would just be bad luck that you have the one in a thousand installation where someone actually did staple it to the studs.

If you do opt to try to drill down, drill two 1 1/2" or larger holes in the top plate of an interior wall so you can look down into the stud cavity. One hole is for the flashlight, one for your eyeball. This will allow you to get started square to the first cross piece of 2x4. I've got to tell you though, drilling two floorplates & two fireblocks without damaging the wall is going to call for some serious good luck.

You might try looking at the plumbing vent stack which is usuall a 3 or 4 " pipe that will go from the basement all the way up through the roof. Sometimes the wood at each floor penetration is cut sloppy enough for you to drop a chain all the way from the attic to the basement or crawlspace.

If you're really lucky, you have a closet on the first floor that lines up with one on the second floor & could run the lines through the closets.

Good luck with this project.
