Houston floods. Harvey, Imelda, Allison and a long list of unnamed afternoons have put water into garages across this metro, and the garage door is usually the first thing the water reaches and the last thing anyone inspects.
The problem with flood damage to door hardware is that it is almost never immediate. The door works fine the week after. The failures arrive one to six months later, and by then nobody connects them to the water.
What to check, in order
- The bottom brackets. These sit at slab level, they are under full spring tension, and they rust from the inside out. A corroded bottom bracket failing under load is a genuinely dangerous failure. This is the first thing we look at on any flooded door.
- The lift cables. They terminate at those same bottom brackets and they sit in the water. Look for rust, fraying and stiffness where the cable meets the bracket.
- The sensor wiring. The photo-eyes mount six inches off the floor, so their wiring is always submerged. Corrosion at the terminals develops over months and produces intermittent faults that look like sensor failure and are not.
- The opener logic board. If water reached the ceiling unit you already know. But surge damage from the outage that accompanied the flood is just as common and far less obvious — it shows up as erratic behaviour, lost programming or a unit that will not learn a remote.
- The bottom section. Steel doors wick water upward through the section. Rust starts inside the panel and pushes the paint off from behind — by the time you see bubbling, the steel underneath is well gone.
- The track and rollers. Silt in the track and grit in the roller bearings will grind both away much faster than normal wear.
What to do in the first week
- Photograph everything before cleaning anything — insurers want to see it as it was.
- Rinse silt out of the tracks with fresh water and dry them.
- Lubricate everything generously once dry: hinges, rollers, bearings, spring coils, cables.
- Do not run the opener until you have looked at the cables and bottom brackets.
- Get the whole system inspected — this is the one case where we would push a homeowner toward a professional visit rather than a checklist.
What insurance usually covers
Flood damage sits under flood insurance, not standard homeowners. If you carry NFIP or private flood cover, garage door hardware and the door itself are generally within scope, and documented photographs plus a written technician assessment make the claim considerably easier. We provide both as a matter of course after a flood event, whether or not you use us for the repair.
Rebuilding smarter
If you are replacing a door after a flood, this is the moment to spend a little differently: galvanised hardware, a properly sealed bottom section, and — if you are in a windstorm county — a rated assembly, since you are already paying for the install labour.
