Landscape contractor Roger Cook and host Kevin O'Connor bundle up and head outside for a few lessons on the different types of snow throwers and how to use them properly.

Then, Tom makes a HOUSE call to help a homeowner replace an old, drafty exterior door with a new pre-hung, energy-efficient unit.
