Allen and Debbie Goldstein have a big house and an even bigger family: three kids, a dog and in-laws all under one roof. They're paying their contractor big bucks to build an extensive addition to the home, but when these homeowners discover the extra square footage means they'll need to upgrade their boiler and HVAC system, they need John's help to save some serious cash. Their contractor will build the shell and they'll do the rest -- adding siding, installing doors, framing and laying a deck and installing a whole lot of tile. If Allen and Debbie can do the work, they'll put over $10,000 in their pocket, gain tons of extra living space and get the "gateway to the backyard" they've always wanted. But with Allen's handyman skills lacking, this addition might need an intervention.
