  • Sealing ductwork in an attic

    Often furnace heating and air conditioning duct work is run though an attic and then back down into the house. Personally I think that this is a really bad idea unless there is absolutely no alternative route. Why? First, most duct work is not sealed where it goes through the ceiling, so a lot...
  • WHICH CAULKING SHOULD I USE?

    -- Oil base, resin base and polyvinyl acetate caulking do not hold up.
