Hello everyone, I have a question about vapor barrier. We are in Northern Canada and own a house that currently does not have vapor barrier in the walls, just insulation. I know that back in the day it was not required to have a vapor barrier...is there anything that we can do to this house to actually make a good vapor barrier in the house without having to tear out all the drywall? Thank you.
You can't. If the insulation has the Kraft paper on it, you are already good to go. Only way to do it properly if needing to update wiring, and replace old plaster walls if still, is to tear down to the bones and start from scratch.

17,000 dryer fires a year, when did you last clean the inside of the dryer near motor or the exhaust ducting?
