Spoke with our PM on Friday. He was in the hallway of our house looking for the creaking floor, which was occurring prior to the hardwood being installed. Over the phone, I tried to explain where the noise was coming from and he couldn't find it. I went up Saturday, found the noise, made a video from my cell of the noise. I also taped a small piece of paper to the area the noise comes from.
I stole this idea from another blogger. There is an 350 degree panaramic app for my phone, let's you take pictures of multiple areas and it combines them. Sometime it works, sometimes it puts things in the wrong place. Click on them to see them better.
