Attic Mold Part II
I had made a previous thread about my mold discovery. This is a continuation of that story.
In February, I finally went into my attic after a year in the home and discovered two vent ducts had disconnected for the bathroom venting and were laying on top of the blown loose fill insulation. I also noticed some black mold on the interior roof sheathing. The mold was in spots and seemed to be concentrated near the areas where the ducts had spilled over. The builder had used duct tape and not the standard foil HVAC tape which is required. I re-attached the ducts which was a pain since the connector to the roof vents was short so I had to use zip ties to keep them in place.
I didn't see any other issues. I talked to my home inspector and he said that I shouldn't worry since the mold is only in a few spots and not spreading and that I connected the vents that there shouldn't be any more moisture problems in the attic. Also that since it was getting warm here, the dry hot air will kill any mold spores or at least prevent them from spreading.
Cut to Today, My task today was to install flooring for the attic.
I went into the attic and noticed that the mold was still where it was before but hadn't grown dark nor had spread. A good thing right? Well, I noticed that the vent duct to the furnace was disconnected and had been blowing hot air into the attic. I fixed this but I also noticed that under the first layer of cellulose fiber insulation, some kind of gold colored wood chip looking pellet stuff, it was all over. I moved some more insulation and noticed that some beams were dark colored and it didn't appear it was mold but rather that the beams had been "baked" a bit, I guess that the hot air baked the wood or perhaps maybe I was looking at mold growth. Anyway as I got maybe five feet from that area I noticed the beams were ok and looked new like they should.
However, I did not want to install attic dek flooring panels on these beams because I think they may not be structurally sound even though they are still dense and don't seem to warp or make noise when I put weight on them. Regardless, I want to remove all insulation from the area where the ducts fell over to about five-six feet to see the damage and to remove the gold looking wood chips or soot that I found to assess the damage to the beams and decide if I can clean and remediate myself or call a professional.
I'm thinking a shop vac would be the quickest way since i am the only one doing this.
Has anyone else had this problem or knows what I may be seeing here and what can be done about this? What are the gold looking wood pellet pieces that I am seeing? Also, is a shop-vac recommended for removing loose-fill insulation?
