Drafty Windows in Older Mandeville Homes: Causes and Fixes

Why Older Windows Start Letting Air In

When a house has been standing through decades of Gulf Coast weather, drafty windows are often the first place the wear shows up.

The biggest culprits are damaged weatherstripping, shrinking or cracked glazing putty, warped sashes, and frames that have shifted a little as the house settled.

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.

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

Clues That Point To Window Air Leakage

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.

The usual signs are pretty consistent: - a visible gap between the sash and frame - a light rattle during gusts - peeling caulk or failed sealant around the trim - condensation problems Mandeville LA homeowners notice on humid mornings - higher energy use without any major change in habits

A draft does not automatically mean the entire window is beyond repair. In some cases the air leak comes from the perimeter trim or caulk line. In others, the sash, balance hardware, or insulated glass seal is the weak point.

You can do a basic test on a windy day. Hold a lit incense stick, a thin tissue, or even your hand along the inside edge of the frame. If the smoke or tissue moves in one spot, that is often the leak path.

What Actually Fixes The Problem

The repair has to match the failure. Small leaks can often be sealed. Bigger problems, like warping or wood rot, usually need more than caulk and hope.

For smaller issues, common repairs include: - replacing worn weatherstripping - recaulk­ing the exterior perimeter - closing minor gaps around the casing - adjusting latches or locks so the sash pulls tight - patching small areas of damaged wood

If the sash no longer closes evenly, or the frame has swollen and shifted, the window may need more involved work. That can mean reframing part of the opening, replacing failed components, or moving to full window replacement.

Knowing When It Is Time To Upgrade

Replacement starts to make more sense when you see any of the following: - repeated drafts after prior repairs - visible rot, corrosion, or frame distortion - condensation between panes that cannot be wiped away - hardware that no longer secures the sash properly - the same rooms staying uncomfortable year after year
