When a simple washer and dryer installation goes horribly wrong, Dawn and Glenn, are left with pipes that back up and leak all over their first floor living space. Not only did the contractor do a number on the plumbing system, he also left a flue pipe unattached to the wall, causing a Carbon Monoxide leak. As work begins, more problems start to surface, literally. John DiSilvia discovers a major ant infestation living behind their walls and in their ceiling and a roof that can't drain properly. JD and his team get to work, sealing the carbon monoxide leak, fixing the downstairs living space that has flooded so many times and creating a new utility room and private space for Dawn and Glenn to do their laundry, the issue that started the mess in the first place.
