What Orangeburg SC Homeowners Should Know About Window Air Leakage

What Air Leakage Looks Like In Everyday Use

Air leakage is not always dramatic. That matters in Orangeburg SC because heat, humidity, and long cooling seasons put constant pressure on window seals and frames.

You may also hear a whistle on windy days, feel movement around the sash, or notice that curtains shift even when the window is closed. In older houses, especially around downtown Orangeburg, this can come from settled framing, worn weatherstripping, or original windows that have simply aged out.

An experienced window replacement company can confirm the cause with a quick inspection.

Why Window Drafts Happen In This Climate

The cause is not always the glass itself. Most air leakage happens where materials move, shrink, or wear down over time.

• Caulk that has cracked or weatherstripping that has flattened
• A sash that no longer closes tightly
• Separations between the frame and the surrounding opening
• Rot, swelling, or termite damage around the frame
• Install errors, old sealant, or both

2. Utility bills rise as the cooling system runs longer to keep up.
3. Humidity finds weak points, and that can show up as condensation or softening materials around the frame.

What To Ask Before You Hire Someone To Fix The Problem
