Hey seasoned's Searching out some recommendation right here. 2d floor of Cape Cod is all knee walls. Now not simplest has the region in no way been air sealed, but the blown in insulation is genuinely poorly done, no rigid or poly-iso at the attic facets of the knee walls; basically nothing insulating knee partitions from unconditioned attic area. My gut says do away with all present insulation and do it proper, however I do not want to create more paintings for myself. There are such a lot of insulation scammers accessible i'm nearly afraid to have a person look at the state of affairs. Tear all of it out and begin from scratch? Depart it in and try and paintings round it? Discover a way to suck out the unfastened fill and re-use? Hard to recognize what to do.
