Drafty Windows in Mandeville? Affordable Fixes and Replacements

How to Detect Drafts in Mandeville

If you feel a breeze near a closed window, you are paying for cooled air to leak out and humid Gulf air to sneak in.

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.

Start by proving the actual leak path rather than guessing.

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