How to Verify a Licensed Window Installer in Louisiana

Why Licensing Matters Before Any Window Project

If the company stalls, changes the subject, or says the paperwork is "somewhere in the office," that is your cue to move on. Good installers are used to these questions because informed homeowners ask them all the time.
