Podcast Episode 757: Window Condensation, Dark Matter on Siding, and What is Affordable?

This week's Fine Homebuilding podcast covers a mix of listener stories, including one with a useful fix for a common cold-weather problem: foggy windows. A listener in Sweden had serious condensation on his windows and water dripping from wall vents after a renovation that included triple-pane windows, added insulation, and air sealing (tightening up a house to cut drafts). The cause was poor airflow for a household of five. He fixed it by installing larger passive fresh-air wall vents, about $30 each, to let more outside air in, and by trimming the bottoms of bathroom and laundry room doors so stale air could flow out to the exhaust fans. The condensation disappeared the following winter. Anyone with a tightly sealed home and foggy windows in winter may be dealing with the same airflow imbalance.

Another listener wrote in about a new spec home for sale outside New Braunfels, Texas: 1,800 square feet, four bedrooms, 2.5 baths, priced at $368,000. He noted some corners cut on construction quality, including thin sheathing and an air conditioning system placed in a vented attic rather than a sealed one, which tends to waste energy. The point raised was that entry-level new homes vary a lot in build quality, and most buyers have little way to judge that before move-in, since inspections typically happen after the house is finished.

A third listener asked the hosts about a dark, oozing stain on his garage siding, suspecting something living in the wall or ceiling cavity. No cause was confirmed in what he shared, just a plan to open up the ceiling and investigate.
