The short version
Florida issues Garage Door Installation as its own specialty contractor category, with its own trade exam and its own scope. Window and door installation is a different specialty. Doing garage door work does not qualify you under a window and door license, and the reverse is equally true.
Why people conflate them
Both are openings in the building envelope. Both are rated assemblies that must resist design pressure. Both use product approvals and Notices of Acceptance, both are permitted work, and both are inspected on anchoring. From a physics point of view they are close relatives.
But they diverge on everything mechanical. A garage door is a moving, counterbalanced assembly carrying its own weight through springs, cables, and drums, often driven by a powered operator. A window or an entry door is not. That mechanical half is precisely what the garage door trade exam concentrates on.
What the garage door specialty covers
What it does not cover: the 120-volt branch circuit feeding a powered operator, which must be subcontracted to a licensed electrical contractor. Structural alterations to the opening beyond the door work also belong to other trades.
Which one do you need?
| The work you sell | Which license |
|---|---|
| Residential and commercial garage doors | Garage door specialty |
| Garage door springs, cables, and counterbalance | Garage door specialty |
| Garage door operators | Garage door specialty |
| Replacement windows | Window & door specialty |
| Entry and patio doors | Window & door specialty |
| Both, as one business | Both, or a broader license |
If your business genuinely does both — common in storm-hardening and impact-window work — you need to be licensed for both, or hold a broader contractor license that encompasses them. Confirm the current category definitions with the DBPR before you commit to an exam.
Choosing a license by the name that sounds closest is an expensive mistake. Check the scope language for the category against the jobs you actually invoice.
What is different about the garage door exam
The Florida Garage Door Installation Specialty Contractor trade exam is 55 scored questions in 2.5 hours, 70% to pass, open book, at a Pearson VUE testing center. It covers seven content areas:
- Introduction & Regulations — scope, product approval, the subcontracting rules
- Tools, Equipment & Materials
- Technical Knowledge — the largest area at 27%: door types, counterbalance, cable drums, wind-load behavior
- Installation Procedures
- Repair & Maintenance
- Electrical Work & Safety
- Health & Safety
Notice how much of that is counterbalance and door mechanics — material a window and door exam has no reason to test. That asymmetry is the clearest signal that these are genuinely different trades rather than one trade with two names.
Both exams, one requirement in common
Whichever specialty you go for, Florida also expects the separate Business and Finance exam, which every contractor takes once, plus the experience, financial, insurance, and background requirements for the category.
License category definitions and scope language are set by the board and change over time. Verify the current scope with the DBPR before choosing an exam or bidding work.
