I assume your home is stick framing.
Putting a hole through the wall, between the studs will get you into the wall cavity. You will still have a bottom plate and sub floor you will need to get through. You can drill up through the sub floor and plate from the basement.
The trick is to find the exact area in the basement to drill the hole.
* Pick the wall space area where you would like to make the wall penetration.
* Next step you will need a drill and a 1/16 to 1/8 inch bit.
* Measure out from the Sheetrock wall, say 2 inches, and drill a small hole all the way through the floor. ( Word of caution here! If you have radiant heat in the floor do not drill.)
* Next insert a piece of wire through the hole about 12 inches. Go to the basement and look for the wire.
* Measure back from the wire 2 inches, (drilled hole to sheet rock) + thickness of rock + about 1 1/2 inches ( approx 4 total inches). Look for nails/s sticking through sub floor sheathing. Drill a 3/4 to 1 inch up through floor and plate.
* If the wall you are wanting to use is an outside wall it can be a little tricky depending on the drill you will be using. An Angle drill works the best. Because of the foundation wall and seal plate you may have to angle the drill bit to drill the hole with a regular drill. In this instance you will have to be careful and not drill out through the outside of the house..... LOL, seeing daylight is a bad sign..... Because you will be drilling at an angle shorten up the distance back from the locator wire. Only measure back about 2 1/2 to 3 inches. Carefully drill hole with a 1 inch bit.
