7 Surprising Insights on Moldy Windows

7 Surprising Insights on Moldy Windows

By Dr. Rodney Russell


The discovery of a "mold-free" house actually being a breeding ground for mold can be quite alarming. This situation sheds light on the subtle ways in which mold can infiltrate windows, often going unnoticed. Here are some key insights:

  1. Beyond Humidity and Temperature: Often, window mold is attributed to indoor humidity or cold exterior temperatures. However, issues like poor sealing during installation, failed window seals, or improperly installed weather strips are frequently the real problems. A newly sealed home should not translate to inadequately sealed windows.
  2. Vinyl Windows' Hidden Issue: Vinyl windows might appear durable, but they're prone to stretching and shrinking with temperature fluctuations. Over time, this leads to air leaks, creating ideal conditions for mold growth.
  3. Mold Accumulation in Windows: In houses with existing mold issues, spores can gather around window elements such as glue and framing, hastening mold proliferation in these spots.
  4. Installation Quality Matters: The installation of new windows doesn't necessarily mean they're well-installed. Some installers, driven by bonuses for quick installations, may compromise on quality, resulting in subpar work.
  5. Economizing in New Constructions: Builders sometimes outsource window installations in new constructions, often choosing less expensive options to increase their profits. Consequently, new buildings might not always feature well-installed windows.
  6. Concealed Mold Risks: Mold can be present around window frames without being visible, and it can develop without typical indications like condensation or seal failure.
  7. Dangers of External Mold: The health implications of mold predominantly outside the home, or confined to window framing and interior walls, should not be underestimated.

This experience highlights the importance of vigilance and an understanding of home construction nuances in preventing mold issues, particularly around windows. It serves as a reminder that unseen factors can significantly impact both our living spaces and our health.
