Is it safe to store valuable antique furniture in an attic?
I have a lot of furniture in very fine condition from the late 19th century. Is it safe to store it in my attic? To my knowledge, there are no animals up there, but would the cold/heat damage it? I am in NJ and an uninsulated attic will see a wide range of temperatures.
Ken above is correct. Papa stored some exquisite antiques in an uninsulated attic in the Cleveland area which suffered significant damage as a result. Wood cracked, finishes orange peeled, joinery swelled, drawers stuck and I had to have them restored at great expense.
