I watched several you tube videos and read carpet installation specifications to learn how.

The one house I am thinking of right now is the one I completely rewired and took the spider web of old knob and tube OUT of the attic.Good access either by inside closet hatch on a 9 foot ceiling,,,ALL the rest of the house the ceilings were lowered to 8 foot with new framework and new drywall 20 years ago. 

. : )I did get someone on You Tube on the phone.

They had to remove the (moldy rotting) flooring & code required them to sono-tube the footings 48inches deep.

There are multiple You Tube videos that show you how to do it. 

Typically, this is done by taking the cardboard tube from a roll of toilet paper or paper towels (or an empty water bottle with the bottom cut out) and shoving a bunch of crumpled dryer sheets inside.

@Timothy Albright I think part of the issue with you tube is anyone can post anything they want...claim whatever they want without repercussion.

I didn't see any knob and tube present which was good but I didn't check the outlets.

To clarify- the house was built in 1920 so most of my extra cost was replacing knob and tube and insulating the walls and attic to code.
