When Great Aunt Reba dies and leaves some money to the Heffley family, they get the chance to make some much needed home improvements. After unsuccessfully attempting to do some of the maintenance and repairs themselves, Greg’s parents realize it’s time to bring in the professionals. The problems continue to multiply, however, as rotten wood, toxic mold, and unwelcome critters are uncovered. When permitting issues threaten to put a hold on the renovations, moving may be the best option for the Heffleys. When the dust finally settles, will Greg and his best friend Rowley be separated for good?
