Is it okay to leave vapor barrier gaps in basement insulation?
I had a flood in my finished basement in January from a sump pump failure. The salvage company cut out 16 inches of drywall and insulation (fiberglass with vapor barrier attached) from the bottom. Unfortunately, when they cut the insulation they sometimes took larger pieces of the vapor barrier. There are a few spots where I can’t feel any vapor barrier (just the insulation) for as far up as I can reach my hand under the drywall. My question is basically is there anyway for me to deal with this without having to cut out more drywall? I’d like to limit the scope of this job as much as possible. The basement walls are poured concrete (7 year old house) and generally quite dry. I don’t get water seeping in from the walls, for example. How bad would it be if I just put in 16 inches of new insulation (or just skipped adding new insulation altogether) and fixed the drywall (or put panelling over it) leaving the vapor barrier gaps? This past winter after the flood, I didnt notice any problems
