Mulberry doesn't sit on the coast, but that doesn't mean storm season passes this town by. Polk County sits squarely in the path of systems that roll across the peninsula from both the Gulf and Atlantic sides, and the afternoon thunderstorms that build over Central Florida from June through September can bring damaging wind gusts even without a named hurricane. For homeowners here, taking the garage door seriously before storm season starts is one of the smartest things you can do.
Your garage door is the largest opening in your home. When it fails during high winds, it doesn't just let rain in. it can cause a catastrophic pressure change inside the structure that blows out walls and damages the roof. This is well-established in Florida building science, and it's exactly why the state has some of the most specific garage door wind-load requirements in the country.
The Florida Building Code requires all garage doors to meet specific design pressure ratings based on your location, wind speed zone, and structure type. These ratings are expressed in PSF (pounds per square force) and must meet or exceed the requirements for your specific garage opening.
Mulberry falls in an inland wind zone, which means it doesn't face the same extreme requirements as coastal counties like Miami-Dade or Pinellas. However, that doesn't mean your door gets a pass. Tropical storms and severe squalls regularly push through Polk County with enough force to stress an older, undersized door. The Lakeland area, just north of Mulberry, has seen repeated storm damage to garage doors in residential neighborhoods in recent years.
If you're unsure whether your current door meets current Florida Building Code wind ratings, that's worth finding out. especially before hurricane season begins in June. Check the door's label or product documentation, or reach out to our team for a wind-load assessment.
Before you spend money on anything, do a straightforward visual inspection. Here's what to look for:
Doors installed before the early 2000s may predate Florida's updated wind-load code requirements and weren't built to the same standard. If your door is approaching 20 years old, it's worth a professional evaluation. Look for bowed panels, cracked sections, rust along the bottom rail, and any sections that flex noticeably when you push on them.
The hinges, rollers, and tracks that support your door are just as important as the door panels themselves. Worn rollers let the door shift in the tracks under wind pressure. Loose hinge bolts reduce the structural integrity of the entire system. During high winds, a door that's mechanically compromised is far more likely to fail even if the panels themselves are rated appropriately.
For a complete rundown of what to look for before calling in a professional, our post on warning signs your garage door needs repair covers these indicators in detail.
Storm prep isn't only about structural failure. it's also about water intrusion. Mulberry receives an average of over 36 inches of rain annually, with the heaviest rain concentrated in the summer storm season. A compromised bottom seal lets water sheet under the door and into your garage floor. Check that the seal is pliable and makes full contact with the ground across the entire width of the door.
For doors that are structurally sound but not wind-rated, horizontal bracing kits can be installed across the back of the door panels to add rigidity. These are a cost-effective middle-ground option for homeowners who don't need or want a full door replacement. They're not a substitute for a properly rated door, but they do meaningfully improve resistance to wind deflection.
If your door is old or underpowered for Polk County's wind environment, replacing it with a modern wind-rated door is the most reliable solution. Current steel and aluminum insulated doors come with clear wind-load ratings and are engineered to meet Florida's code. The investment pays off both in storm protection and in the lower insurance premiums some carriers offer for certified wind-resistant upgrades. Check with your homeowner's insurance agent. some Florida insurers do provide discounts for wind-rated garage doors.
Garage Door Mulberry can help you explore the right door for your home's specific opening size and wind zone without overselling you on features you don't need.
When a tropical storm or hurricane watch is issued for Polk County, there are a few immediate steps that make a difference:
1. Disconnect the automatic opener. This sounds counterintuitive, but if power is lost during the storm, an opener that hasn't been manually disengaged can jam the door in place and make emergency exit impossible. Pull the red emergency release cord. 2. Don't lock the door from the inside using the slide bolt alone. The slide bolt keeps the door from being manually lifted, but it does almost nothing against wind pressure pushing inward on the panels. Only a properly installed door with wind-rated hardware addresses that. 3. Remove items stored against or near the door inside the garage. If a door does fail under extreme pressure, anything stored near the opening becomes a projectile hazard. 4. After the storm, inspect before you operate. Debris, track shifts, and spring damage are common after high-wind events. Running the opener on a damaged system can cause further mechanical harm. If anything looks off, read through our spring replacement guide and call a technician before attempting to operate the door.
If you're thinking about upgrading your opener before storm season, look for models with battery backup. When a storm knocks out power. common in Mulberry during severe summer weather. a battery backup opener lets you get in and out of your garage without having to disengage the mechanism manually in the dark or rain. It's a practical feature that pays for itself the first time you need it.

Q: Does my Mulberry garage door need to be hurricane-rated? A: Not to the same standard as coastal counties, but it does need to meet Florida Building Code wind-load design pressures for Polk County's wind zone. Older doors may fall short of current requirements. If you're unsure, a labeled door should show its design pressure rating. if there's no label or the door predates 2002, it's worth having a professional check it.
Q: Can I use a regular garage door lock to secure my door during a storm? A: A manual slide lock prevents unauthorized lifting but provides minimal resistance against wind pressure pushing inward on the door panels. For real storm protection, the door itself. its panels, hardware, and tracks. needs to be wind-rated. Locking an undersized door doesn't make it storm-ready.
Q: How often should I have my garage door inspected in Mulberry? A: Once a year is the standard recommendation, and the best time is right before storm season begins in June. A pre-season inspection lets you address any hardware wear, weatherstripping issues, or structural concerns before conditions deteriorate. Book a seasonal checkup and you'll head into summer with one less thing to worry about.
