A lot of the older farmhouses here sit on pier-and-beam or vented crawlspace foundations that were never sealed against the humidity. Cold floors in winter and musty smells in summer are the usual complaints. On the custom-build side, we get called for spray foam in conditioned attics and exterior walls, since these homes tend to get more attention to detail than a standard spec house.
We also do a fair amount of work on outbuildings and detached garages: workshops, barns turned into living or storage space, and other buildings that need insulation just like the main house.
Main house, outbuilding, or new build, we'll tell you exactly what it needs.
