Pre-Hurricane Sliding Door Inspection: 12-Point Checklist for Florida Homes

Why does a pre-hurricane sliding door inspection matter in Florida?

A sliding door is one of the largest single openings in a typical Florida home. During a hurricane, that opening sees wind pressure, wind-driven rain, and potentially debris impact. A door that is structurally sound, properly sealed, and locked securely can withstand a significant storm. A door with worn rollers, a failed lock, deteriorated weatherstripping, or a clogged weep system can fail in ways that compromise the entire home, from water damage to roof uplift caused by internal pressurization.

The 12-point pre-season inspection catches the issues before they become emergencies. Alpha runs this inspection across all 13 service counties starting in May, and the same checklist works for a homeowner doing the visual portions themselves.

What are the 12 checkpoints?

Each checkpoint has a pass/fail criterion and a specific corrective action if it fails. Run them in order; later checkpoints sometimes confirm or refine the diagnosis from earlier ones.

1. Roller condition. Test slide effort, listen for grinding, and check for visible drop. Fail = replace rollers.
2. Track integrity. Inspect for corrosion, gouging, debris. Fail = clean, polish, or replace track.
3. Lock function. Throw the lock with the door closed. Fail = align panel or replace lock cartridge.
4. Lock pin engagement. Confirm that lock points actually enter strikes. Fail = align strikes or replace.
5. Frame structural integrity. Look for warping, cracks, separation from the wall. Fail = professional structural assessment.
6. Weatherstripping. Inspect for compression, tears, gaps. Fail = replace seal.
7. Weep hole function. Verify that drainage holes at the bottom rail are open. Fail = clear with thin wire.
8. Glazing bead and seal. Look at the glass-to-frame seal for cracks or shrinkage. Fail = re-bed glass or replace seal.
9. Florida Product Approval label. Confirm the FPA number is present and matches the wind zone. Fail = consult original install paperwork or upgrade.
10. Screen frame and roller. Check screen door operation and integrity. Fail = repair or replace screen.
11. Handle security. Operate the handle and check for play or loose mounting. Fail = tighten or replace handle.
12. Panel-to-frame alignment. Look for even gaps at top and side, vertical plumb of the closed panel. Fail = adjust rollers or reseat panel.

How do I check rollers and tracks myself?

For rollers, the test is slide effort. Stand at the open position and slowly slide the door closed using only your fingertips. The door should glide without resistance, grinding, or binding. Any catch or rough spot means rollers should be inspected by a technician. For the track, vacuum the bottom channel with a brush attachment to clear debris, then visually inspect for corrosion (white aluminum oxide bloom or rust streaks) and for gouging (polished grooves where rollers ride). Surface corrosion is treatable; through-corrosion or deep gouging is professional repair territory.

What about locks and weatherstripping?

For locks, close the door and operate the lock to its fully-thrown position. Then with the door locked, gently apply pressure to the panel toward the open position. A properly engaged lock will hold the panel firm with no movement. If the lock throws but the panel still has play, the lock points are not fully engaging the strikes, which is an alignment issue rather than a hardware failure.

For weatherstripping, run a finger along the seal where the panel meets the jamb. The seal should be soft, intact, and consistently in contact when the door is closed. Tears, gaps, or visible compression set (the seal looks flat and stays compressed when the door opens) are fail conditions. Weatherstripping is one of the most overlooked maintenance items and one of the most consequential during a storm; a failed seal lets driven rain into the home.

What is a weep hole and why does it matter for hurricanes?

A weep hole is a small drainage opening at the bottom of the door frame, typically two to four per opening, that lets water that gets past the outer seal drain back outside instead of pooling inside the frame or seeping into the home. During heavy rain or hurricane wind-driven rain, the weep system is the primary defense against interior water damage.

Weep holes clog with debris over time, especially in coastal homes where sand accumulates, and in homes near landscaping where mulch and leaf fragments work their way in. To check, locate the weep holes on the exterior side of the bottom rail. They should be open. To clear, use a thin stiff wire or a small Allen key to gently dislodge debris; do not enlarge the hole.

What does Florida Product Approval mean for hurricane prep?

Florida Product Approval is the certification that confirms a door assembly has been tested to current Florida Building Code impact and design pressure requirements. The Approval is identified by a sticker on the door, typically on the bottom rail or inside the frame, with a unique number that can be looked up in the state database.

If your home is in a wind-borne debris region (most coastal Florida and significant inland portions), an impact-rated assembly with current Approval is your protection against debris and your qualification for insurance wind-mitigation credits. A non-impact door in a wind-borne debris region is a code non-compliance risk and an insurance disadvantage. The pre-hurricane inspection is a good time to verify the Approval is intact and the doors are appropriate for your zone.

What if my inspection finds problems?

Address them before the next named storm. The hurricane season runs June 1 through November 30, and Florida service availability tightens significantly during active storm periods. The roller, lock, weatherstripping, and weep hole repairs are routine work that Alpha completes within a few days when scheduled in advance. Frame structural issues and Florida Product Approval upgrades are larger projects that may take longer; start the conversation early in the season.

Across the 13 counties Alpha covers, the pre-season inspection is offered as a standalone service. The cost is modest, the time is well spent, and any failures identified can usually be addressed before they become emergencies.
