It seems that after 7 years, a new house will need work. Ours is 7.5 years old in June. As I write this, sheets of plastic hang from the ceiling and doorways to keep in the white dust and scrapings as we are having some ceiling work done where the mastic? tape has separated, leaving cracks in the paint on top of it..
It also seems that 7 years in the attic turns a sealed ceiling paint can into a brick. Happily, the label was still legible and I visited Sherwin Williams to get a replacement.
Can you imagine what a little 13 week old puppy would do if he saw that hanging plastic? I can. He won't.
