Drafty Windows: Common Causes and Fixes in Montgomery County, MD

What Usually Causes A Window To Feel Drafty

When a window feels cold, rattles in the frame, or lets in a steady ribbon of air, the problem is usually more specific than "old window."

Here in Montgomery County, MD, we see the same patterns again and again, weak weatherstripping, worn sash balance parts, dried-out caulk, and frames that are no longer perfectly square.

Not every draft comes through the glass. Quite often, the air is sneaking in around the perimeter, where the window was installed to begin with.

A quick check with your hand can tell you there is a problem, but it will not tell you whether you need new weatherstripping, a repair, or a full window replacement.

How To Match The Repair To The Problem

A good technician will check the seal, the hardware, the sash fit, and the condition of the frame before recommending any work.

With aging windows, it is common to find a loose sash, a worn seal, and a slightly out-of-plumb frame all at once.

Signs You Need Window Replacement

Energy savings matter most when the old units are leaking air and losing heat around the frame, not just through the glass.
