Drafty Windows in Older McLean Homes: Causes and Solutions

What Makes Older Windows Feel So Leaky

In older McLean homes, drafty windows are one of the most common comfort complaints, especially once the weather turns cold or windy.

The leak is often in the parts around the glass, where settling, worn seals, and aging materials create small gaps that only show up when temperatures drop or the wind picks up.
