I recently purchased a home and have begun to do renovations on the basement. I am starting to look at insulation and so I have been researching what the best way would be to do that. The problem I am having is that the house was built in the 70s and has no moisture barrier between the cement wall and the studs. What are my options for insulating? Is there a way to install moisture barrier with the wall frame still up? I’m dreading the work and money it will cost if I have to remove the framing to redo this insulation.
As a note, the house has been around 50 years without a moisture barrier, what are the benefits of putting one in now if there have been no moisture issues for close to 50 years?
