Matt, Patrick, and special guest former FHB editor Andy Engel take listener questions on how to become a good remodeling contractor, the strength of spray foam, and adding to an existing deck.

This week the regular podcast crew hears from listeners about insulating brick row houses and the limitations of the Bonfiglioli wall system. Then they take questions about heating a whole house with a pellet stove, the limited options for affordable shower valves, and how to strengthen the foundation of a rustic cabin. The crew also discusses how to keep the height of an auxiliary dwelling unit to a minimum.

This week’s installment revisits Tony’s planned grade-level deck and we hear from a listener who’s married to a carpenter bee researcher. The crew explores the best way to remove ceiling stalactites and how to convince a carpenter to take on a small rot-repair job. Then they hear from a home-performance contractor irritated by the lack of airtightness testing in Northern New York and discuss how to keep a brick walkway looking good.

The gang hear from listeners about insulating brick buildings and how to be a good apprentice before tackling questions about about missing ductwork, construction details for a watertight deck, and a 15-point plan for improving a heating and AC system.
