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.

You will find simple tests to pinpoint leaks, quick fixes that actually hold up in our humidity, and honest guidance on when replacement pencils out.

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.

Use a simple smoke pen or an incense stick along the sash edges and interior trim. If the smoke drifts, you just found a leak path.

Condensation around the interior glass tells a different story than fog trapped between panes.

Repairing Drafts in Mandeville

Fixes work when they address the precise weakness, not just cover it.

The Gulf climate punishes cheap foam that collapses in a season, so pick denser profiles that spring back.
