Drafty Windows in Older Mandeville Homes: Causes and Fixes

Why Older Windows Start Letting Air In

Drafty windows in older Mandeville homes usually are not a mystery. They are the result of years of movement, wear, and weather exposure that slowly open small paths for air to sneak through.

Most drafts trace back to one of a few familiar problems, worn seals, gaps around the frame, sticking sashes, or wood that has swollen, dried, and moved over time.

In Mandeville, humidity makes the problem worse. Wood components absorb moisture, then dry out and contract. That cycle opens tiny gaps that are easy to miss until you stand near the window on a breezy day and feel the air moving.

If the home still has original windows, the draft may simply reflect the limits of the window design itself, not just a repairable defect.

How To Tell The Draft Is Coming From The Window

Drafty windows usually announce themselves in subtle ways first. A room may feel uncomfortable around the window, even if the thermostat says the house should be fine.

When Replacement Makes More Sense Than Another Repair
