Our house was built in 1954 and the insulation installed then is still there. About 25 years ago my husband added some additional insulation but I beleive it now has lost its effectiveness. In addition, the insulation is dirty, there is mice up there, and a lot of stink bugs. I would like to replace all the insulation but my husband dismisses the idea. Kindly let me know what you think.
