Drafty Windows in Mandeville? Affordable Fixes and Replacements

Identifying Drafts in Your Home

Drafts in a Mandeville home are more than a nuisance, they are a steady drain on comfort and AC dollars.

Let’s walk through practical ways to diagnose the problem, cost-effective repairs you can do or hire out, and clear signs that it is time to replace the unit in Mandeville LA.

Before you spend on glass or frames, confirm where the air is getting in.

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

On a still morning, close the HVAC vents in the room, light an incense stick, and move it slowly around the sash corners, meeting rails, and trim. Watch the smoke get pulled into any gap.

Press temporary tape over the joint. If the tape buzzes or lifts in the wind, that spot is leaking.

Moisture on the room side of the glass usually means indoor humidity or a cold surface, while haze between panes points to a failed IGU seal.

When to Replace Windows
