HOUSTON GUIDE

Wind on the door and floodwater on the Houston slab

The door bows inward while the storm is still blowing, or you come back to a bay where the waterline is painted on the drywall and the opener was under it. Houston is on a hurricane-exposed Gulf coast, and garage floors have flooded in storms people still name, including Harvey. This page does not list rainfall totals or casualty figures. It covers two separate injuries: wind on the door, and floodwater in the equipment. A wet opener stays off and unplugged.

Wind and water are not one repair

Wind loads the door as a broad panel. It can bow the sections, rip a track bracket off the jamb, or drive debris through the skin. Floodwater loads the room from the floor up. It soaks the opener, the outlet, the wall button, the photo-eye wiring, and anything stored on the slab. A door can suffer either injury or both. A crew that only straightens the panels and then asks you to test a motor that was underwater has skipped the dangerous half. Refuse that test.

Look from outside before you wade in. If the door is off the track, leaning, or held by one cable, stay out from under it. If water is still standing, the electrical system is not a curiosity. Household storm guidance belongs with Ready.gov's hurricane pages and with the forecast from the National Weather Service, not with a guess about when the bay is safe to enter. The door is part of the house shell. It is not a shelter, and it is not a project to start while the warning is still active.

A flooded opener stays off

If floodwater reached the opener, the receptacle, or the wall control, leave them off and unplugged. Do not dry the housing with a fan and restore power to see if the light comes on. Water and line voltage in a garage are how people get hurt after the storm has already passed. The same rule applies if the unit was submerged in an earlier storm and someone dried it then. Say so. A motor with that history is not a reset-button problem.

Photo eyes and low-voltage wires can be wet while the motor hung higher and stayed dry. That split is worth describing, because the eyes might be the only electrical loss, or they might be the visible end of a wet circuit. You do not sort that with a plug. An electrician or a door technician who will not energize a wet box should make the call. Until then the wall button is not a test switch. The door, if it is still on its tracks and the spring is intact, may be moved by hand only with the rules below.

Moving the door by hand after the storm

Only with the door fully closed should you disconnect the opener, and only if you need to and the panels are still in the track. Lift carefully. If the door feels dead heavy or crooked, stop. A torsion spring that took a shock, or a cable that jumped the drum when the door flexed, will not hold a manual lift. Do not wind anything. Do not grab a loose cable. The page on a broken torsion spring is the ban on that work, and it applies even more when the shaft may have been sprayed with dirty water.

If the door is open and crooked, leave the emergency release alone. A weak spring can drop the door once the trolley lets go. The page on an off-track door is the stance: no prying, no walking underneath. Wind damage and a cable failure look similar from the driveway. The technician needs to know which side sags and whether debris hit the outside face. You do not need to drag the panel back into line to show them.

Cables, tracks, and a door that flexed

A door that bowed and sprang back can still have a cable that unwound, a roller out of the curve, or a hinge with pulled screws. Those parts fail on the next powered cycle, which is why the next cycle should wait. The notes on cables and rollers name what to point at from the side. Rust that was already on the hardware before the storm is part of the story. Flood silt in the track is the new part. Do not hose the opener while you rinse the rails.

Rinse the slab and the track only after the power to that bay is off, including the opener. Grit left in the vertical rail will grind rollers if you run the door anyway. Wipe photo eyes if they were splashed and the opener itself stayed above the water. Then stop. A clean lens does not certify a wet motor. If you smell gas near a water heater or a garage heater that was flooded or shifted, leave the building, do not flip switches, and from outside call the emergency number on the CenterPoint Energy bill. CenterPoint supplies natural gas for many Houston addresses. Use the number printed on that bill.

Wind ratings and the offices that review them

A replacement door may be sold as wind-rated. Do not take a verbal mile-per-hour claim as the rule for your block. Any wind-rated door still has to be compared with what the Houston Permitting Center currently asks inside the city, or what Harris County asks in unincorporated areas. This page does not print a number for them. Rules change, and an address just outside the city is a different counter. Ask the company to put the comparison in the proposal before the old door comes down.

Katy, Pearland, Sugar Land, and Pasadena handle their own building questions as separate cities. The Woodlands is a nearby community with its own rules. If the storm repair is a new door, the hiring questions matter more than the catalog. The list of questions before hiring covers a written scope, insurance, and who pulls the permit. A spring and cable repair on a door that stayed in the opening may be a smaller question. Ask rather than assuming the storm made every job a permitted replacement.

What to write down once the bay is safe to enter

Photograph the waterline, the opener, and the outside face of the door from a dry place. Note whether the power was on when water entered, if you know. Note a bowed panel, a gap at the jamb, and a track bracket that pulled screws out of the wall. Those pictures help an insurer and a technician, and they keep you from standing under the door to explain it. They are not a repair.

When you call, lead with water and wind as separate sentences. The opener was under water, or it was not. The door left the track, or it did not. Someone smelled gas, or they did not. A company that can stock a spring is not always the company that should re-energize a wet circuit. You are allowed to hire those as two conversations. The bay can wait with the door down and the breaker off. It should not wait with a plugged-in motor and a crooked panel.
