Drafty Windows: Causes and Fixes for Montgomery County, MD Homes

Why Drafts Show Up In The First Place

When a window feels cold or leaks air, the problem is often more specific than "old window."

In Montgomery County, MD homes, the usual culprits are wear, movement, and gaps that were never sealed as well as they should have been.

The Most Common Causes Of Drafty Windows

Most draft complaints trace back to one of a few recurring issues.

When the compression seal wears out, the window may still latch normally, but it no longer blocks air the way it should.

• Deteriorated sealant on the exterior trim
