The appeal of a casement window is straightforward. Once the sash closes and locks, it compresses the weatherstripping along the entire perimeter, and that tight contact helps reduce drafts that older windows often leak through.

In Bethesda, that matters in more than one season. During humid summers, an air-leaky window does not just let conditioned air escape, it also invites warm, moist air inside, which can make rooms feel sticky and force the AC to work harder.

When A Better Seal Is Not The Only Issue

If the sash sticks, the frame is warped, the glass fogs between panes, or the room still feels drafty after repairs, the window may be near the end of its useful life.

When the fog is between the panes, the issue is almost always inside the insulated glass unit. At that point, the window is no longer insulating the way it should.
