Think that was a good one? Try this one. Back in 04 I was sitting in den watching the tv and my neighbor looked up and noticed that my overhead fan looked funny. Huh? I noticed the cap that covers the part of the fan was a lot smaller than I remember when it was installed. Got a ladder to take a closer look thinking " is the fan moving UP into the sealing ?" As I was lightly pushing on the sealing ( bad move) all of a sudden 3/4 of the 15x15 sealing came crashing down around me and my neighbor! After the shock, I started to check out what was the cause,and what I found was that when the sealing was installed two layers of sheet rock were used and they measured ! inch thick,and each one had about a hundred 1 and a quarter inch nails holding the panel in place. Sooo..over time, the heat,cold,heat, of the years let the nails work loose and then the weight pulled them down. It took me about a day to clean the mess up,but what the longest time was removing the nails. Lucky for me I have a neighbor who is in the dry wall trade and he came in and redid the sealing to better than new for $500 start to finish. Oh yeah...called my insurance co., and guess what they told me? Yep,contact the builder!!! The same co. This answered my question as to why I had all these cracks in all the rooms in the house. Over the next year I had my drywall neighbor and I replaced all the sealings in the house in return for me maintaining his 3 work vehicles,(you know how construction workers treat trucks) for the next 3 years. Sooo, now I have a new bathroom and sealings and Im waiting for Murphy to strike again. And I am NOT going to ask myself "whats next"
