Need Wall fishing Suggestions
Posted 28 April 2005 - 04:44 PM
An electrician pre-wired coax in a 2.4 million dollar home. Only. he didn't put a phone line or more than a single coax in the wall.
The customer wants TIVO, meaning, we need two wires and a phone line. (Wireless modems aren't recommended with TIVO).
After the electrician did his part, someone came an sprayed foam insulation in the holes beween floors. Then the insulation folks came in and put in interior insulation, and then the wall was drywalled. We suspect, but can't be sure, they may have tacked the coax in the walls.
So --- how would you get a new wire straight down through from the attic, through the second floor, to the first floor, WITHOUT going through the now-finished wall coverings on the drywall? Keep in mind, the original coax doesn't seem to want to move so you can't use it to pull back a new wire.
Thoughts and ideas welcome.

For good reason, I never criticize someone until I've walked a mile in their shoes. If they don't like what I say, what're they gonna' do? I'm a mile away. And they have no shoes!

First, I will describe the interior wall drop to the first floor.
First, remove the entire electrical box into which the original cable is threaded.
I'd drill a very small 1/4" pilot hole some 1-1/2 inches to the side of the current cable entrance hole. If you hit thin air, this is the side int which that you want to proceed. Then, using a 2-9/16 inch self feeding plumber/electrician's bit to cut a hole into the 2x4 top plate into the wall cavity. I'd use a very bright xenon flashlight like a Scorpion and look down into the cavity. If you see a firestop, you'd need to use a 6 foot long 3/4" flex bit like a Greenlee (Home Depot) to drill through it into the next cavity. Be sure it is spaced midway between the walls. If the cavity is empty to the floor, used the same bit with a five foot extension, drill through the floor plate 2x4 into the cavity between the floor and the ceiling and into the first floor wall cavity. Withdraw the bit back through the attic. Using 1/4" Greenlee extension rods (Home Depot). run the rods into the cavity until you reach the floor plate of the first floor. If you measured correctly, you will see the fiberglass rod in the wall cavity, through the electrical box hole.
Exterior walls can be handled easily, if you are working with vinyl siding. If this is so, please indicate that you want a discussion on that.

Customer will have to pay a bunch of money to have this done, so ...
No matter what, he's gonna be pissed at someone - make sure it's not you.

It's hard to know what the future developments are and what future cabling need are.
