How to Identify Your Sliding Door Manufacturer in Florida

When customers call us about repair, the first question I ask is “what brand?” Because PGT, CGI, Andersen, and Pella all use different hardware geometry — and identifying the brand correctly is the difference between same-day repair (we have the right parts) and 2-week delay (we need to special-order). Here’s how to identify your manufacturer in 5 minutes.

Where to find sliding door manufacturer identification

1. NFRC certification sticker (most common)

The National Fenestration Rating Council label is mandatory on new windows and doors. Look for a clear adhesive label on the glass corner or on the frame. It shows brand, model, NFRC ratings, and certification info. Located on most doors installed after 2005.

2. HVHZ / Miami-Dade NOA label

Hurricane-rated doors in Florida HVHZ counties (Miami-Dade, Broward, Palm Beach, parts of Charlotte/Collier/Lee/Indian River/Brevard) have a separate Hurricane Velocity Hazard Zone certification label. Shows manufacturer, NOA number, and certification details.

3. Frame embossing or stamping

Look at the top of the frame or the inside edge of the door panel. Some manufacturers emboss their name directly into the aluminum. PGT, CGI, and Fleetwood often do this.

4. Handle or lock branding

Some handles or locks have brand identification. Often a small embossed brand name on the metal of the handle. Check carefully.

5. Original construction documents

If you have the home construction or warranty documents, manufacturer is documented there. Most homeowners don’t keep these but worth checking if available.

Step-by-step manufacturer identification

Take 5 minutes:

1. Look at all visible glass corners. Check each corner of each panel for a printed NFRC sticker. Sometimes covered by tinting film — look carefully.
2. Examine the frame extrusion. Look at the top of the frame and the inside edge for embossed text. Run your finger over the surface — embossed text feels raised.
3. Check handle and lock hardware. Some brands stamp the handle metal. Look on the inside of the handle assembly.
4. Open the door and look at the bottom edge. Some manufacturers stamp brand info on the bottom of the door panel where it’s hidden during normal viewing.
5. Photograph anything you find. Send photos to us — we can usually identify brand from clear photos of distinctive features even without explicit labels.

If you’ve checked all these and still can’t identify the brand, we can identify on-site by looking at distinctive geometry — roller mounting, latch design, track profile.

When manufacturer matters for repair

Brand identification is critical for:

• Roller replacement. Each brand uses different roller geometry. Wrong roller = doesn’t fit or causes premature failure.
• Lock or handle replacement. Brand-specific. Generic replacements often have alignment or finish issues.
• Glass replacement on impact-rated systems. Maintains HVHZ certification only with OEM-compatible glass.
• Warranty claims. Manufacturer-specific. Need to know who to contact.
• Sourcing replacement parts. Online ordering requires accurate brand identification.

Why manufacturer identification matters in Florida

Florida’s sliding door market has unique characteristics:

More brands in market. Florida has more sliding door brands sold than continental markets — PGT WinGuard (the dominant local brand), CGI (Miami-based hurricane specialist), Fleetwood (high-end), Western Window Systems (premium), plus national brands like Andersen, Pella, Marvin, Milgard, JELD-WEN, Simonton.

Hurricane certifications matter. Florida Building Code HVHZ certification means specific manufacturer testing. Replacement parts must match certified specifications to maintain code compliance. Generic parts may void hurricane rating.

Builder shortcuts in some Florida construction. Some homes have unbranded “builder special” sliding doors. We can usually identify the actual manufacturer by looking at distinctive features, but it takes professional eyes.
