We have an older house, which means there is always something to fix or upgrade.  We found out that our windows were leaking water into the basement when ever the sprinklers would turn on in the middle of the night.  One of the solutions to fixing this problem is to apply silicone caulk within all gaps and cracks of where the window meets the house. This will satisfy requirement 2b. of the Home Repairs Merit Badge. 

Take a look at the video to see how easy it is to apply and fix.
