Leave it to good ole Mother Nature to lend a helping hand. After weeks and weeks of rain, we came to the conclusion that most all the leaks could be traced back to the windows and rotted caulk. The remedy? Removing each and every window, scraping and cleaning them and the metal window frame, and then reinstalling and caulking. How did we do it in persistent rain? Well, it's amazing what you can accomplish with a little ingenuity (and a few logs).
This was by far the most grueling and time consuming task yet, but Lou Dog didn't seem to mind.
