How to Verify a Contractor's Florida Window Installation License

What A Valid License Tells You About A Window Installer

In practical terms, that often means a certified or registered contractor in a category such as building, residential, or specialty work, depending on the project scope and local requirements.

For a homeowner, the important part is not the marketing name on the company van. It is whether the license fits the scope of the project and is currently active.

• The license type fits window installation work.

The Records And Documents Worth Checking Beyond The License
