@TheEvilGreebo I've never seen a rigid duct installation that had all the long-seams taped... so while I agree that the elbow probably should be taped, it aint the end of the world.
I added a closet added to a room. There was no crown molding that matched at HD or Lowes. Is there anything I can do to try and find a match? I would like to complete the project. The home is a 1920's bungalow in MA.
At one time in history, the pun was considered the highest form of humor. This was sometime before plumbing was invented and people also thought crap in the city gutter was high class... ;)
