I have a finished basement where the builder added a plastic vapor barrier between the fiberglass insulation and a suspended ceiling. It is stapled to the joists.
The problem is the vapor barrier gets in the way of maintenance and ends up torn (or filled with mouse debris). I recently installed a new circuit and needed to run the wire on the joists in the ceiling. I had to pull out a bunch of the vapor barrier.
Additionally - the suspended ceiling supports have to penetrate the vapor barrier. Does this mean it was leaky to begin with and likely didn't work anyway?
Since I have owned the house I don't think the vapor barrier has ever been 100% intact - and now it's even more so. Is this a problem?
