Two couples, Stacy and Peter, and Donna and Bill, each own one half of a 100-year-old Victorian home. These two semis share the same leaking porch that's rotting and falling apart for the second time in five years, even though the porch had been entirely rebuilt and the eaves trough had been replaced three times. The issue with the two families has always been that the water comes from one house and ruins the other. Solving the issue means sharing in the costs, something the homeowners with the least of the rot issues have been reluctant to agree to. Mike steps in and mediates the issue, pointing out the benefits of having this done right for both families. After getting the green light from both parties, he and his crew attack the problem at the source, the roof, and work their way down to include new eavestroughs, downspouts and restore the brickwork to its former glory.
