Nobody in Lumberton needs to be told that flooding is a real threat. Hurricane Matthew in 2016 dumped 20 inches of rain and pushed the Lumber River 11 feet above flood stage, sending water through thousands of homes across west and south Lumberton. Two years later, Hurricane Florence arrived and did it again. worse. Over 500 structures were damaged in Robeson County during Florence alone, and entire streets were left abandoned in the aftermath. The city has since invested heavily in flood mitigation infrastructure, but the reality for homeowners is that flooding can still happen, and the damage it leaves behind on homes. including garage doors. is often discovered slowly, long after the water is gone.
If your garage took on water at any point, whether from a named storm or a severe local rain event, here's what you need to inspect before small problems become expensive ones.
A garage door system has more components than most people realize. springs, cables, rollers, tracks, hinges, the bottom seal, the opener motor, and the door panels themselves. Floodwater doesn't just wet these components; it leaves behind sediment, bacteria, and mineral deposits as it recedes. In Lumberton, where the Lumber River carries clay-heavy runoff, that residue can gum up moving parts, accelerate corrosion, and compromise the structural integrity of the door long after everything looks dry.
Steel components. springs, cables, and tracks. begin rusting from the inside out after being submerged. You may not see the rust for weeks or months, but by then the corrosion has already weakened the metal. This is particularly true for springs, which have tight coil-on-coil contact surfaces where moisture gets trapped.
The bottom seal (the rubber strip at the base of the door) is often the first component to fail after flooding. It absorbs water, loses its flexibility, and no longer forms an effective barrier. meaning the next time it rains heavily, water gets in more easily than it did before.
Wooden door panels or trim, which are still common on older homes in established Lumberton neighborhoods, can warp, swell, or delaminate after prolonged water exposure. Even composite and steel doors can develop compromised insulation layers inside the panels if water infiltrated the seams.
Work through this list after any significant water intrusion into your garage:
Run your hand along the entire bottom seal. It should feel consistently pliable and sit flush against the ground. If it's cracked, stiff, brittle, or no longer making full contact with the floor, replace it. This is one of the most affordable repairs on a garage door and one of the highest-impact ones for keeping future water out.
Look closely at your torsion or extension springs and the lift cables. Surface rust that appears reddish-orange and feels rough to the touch is a warning sign. Any visible pitting, flaking, or thin spots in the metal means the component needs replacing before it fails under load. Don't operate the door repeatedly if you suspect spring damage. the emergency release features on your opener exist for situations exactly like this.
Disconnect the opener by pulling the red emergency release cord, then manually lift the door to about waist height and let go. A properly balanced door should hold in place or drift very slowly. If it falls quickly or shoots upward, the springs have likely been compromised and the balance is off. This needs professional adjustment.
With the door closed, look along both vertical tracks for bends, dents, or separation from the wall mount. Floodwater can undermine the concrete or drywall anchors holding the tracks. Rollers caked with dried sediment should be cleaned and lubricated. or replaced if the bearing is seized. For a deeper look at roller conditions and lifespan, see our complete roller replacement guide.
If the motor unit was submerged or significantly splashed, do not plug it back in without inspection. Water intrusion into the motor housing or circuit board can cause immediate electrical failure or create a fire hazard over time. If the unit ran during or shortly after flooding, have a technician evaluate it before continuing to use it. Families who lost power during Matthew or Florence. over 75% of Robeson County customers lost power during Florence. and then resumed normal operations afterward may have restarted damaged equipment without realizing it.
The most overlooked post-flood issue is the garage floor-to-door threshold. If the concrete floor heaved, settled, or cracked from water saturation. which is common in Lumberton's low-lying areas along the river corridor. the door may no longer seal properly at the bottom even with a brand-new seal installed. Before investing in repairs, make sure the floor surface is level and intact where the door meets the ground.
Another frequently missed issue is panel insulation degradation. Insulated garage doors have foam or polystyrene cores that can absorb moisture if the door's edge seals were compromised by flooding. Wet insulation loses its thermal performance and can promote mold growth inside the panel. This is especially relevant given how often Lumberton summers trap heat. a door with compromised insulation will make your garage noticeably hotter. Our post on insulation R-value can help you understand when a door has lost enough thermal performance to warrant replacement.
For doors that experienced multiple flood events. and Lumberton has no shortage of homeowners in that situation, with some properties flooded by both Matthew and Florence. cumulative damage can make repair less cost-effective than replacement. If your door is more than 15 years old, showed corrosion before the flooding, and now has multiple compromised components, the honest answer is often that a new door makes more financial sense. A new insulated steel door also gives you better water resistance and peace of mind going forward.
Homeowners in Shannon, Rowland, and Bladenboro face similar flood exposure concerns and should apply the same post-storm inspection routine. If you're unsure what you're looking at or whether a component needs replacement, reach out to us. we'd rather help you make an informed decision than oversell a repair.

How soon after flooding should I inspect my garage door? As soon as it's safe to enter the garage. ideally within 48,72 hours of the water receding. The longer corroded components sit wet, the faster they degrade. Sediment that dries inside rollers and tracks is also much harder to clean out once it hardens.
My garage door looks fine after flooding. Do I still need to inspect it? Yes. Flood damage to springs, cables, and internal insulation is often invisible from the outside until the component fails. A door that appears undamaged can have significantly corroded springs or a compromised opener motor. A professional inspection takes 30,45 minutes and can catch problems before they become emergencies.
Can flood-damaged garage door components be cleaned and reused, or do they need replacing? It depends on the component and the extent of exposure. The bottom seal almost always needs replacing after significant flooding. Springs and cables that show any rust, pitting, or stiffness should be replaced. the cost of a failed spring is much higher than preventive replacement. Tracks can often be cleaned, dried, and relubricated if they're structurally sound and haven't bent or separated from their mounts.
