Why is an open garage door a problem when a storm is coming?
Wind that pours into an open garage builds pressure inside it and pushes outward on everything around it, from the ceiling and the roof over the garage to the door into the house. A door that will not shut or will not stay down is an emergency garage door repair call to make while the sky is still quiet, not the morning after.
Picture the garage as a box with one wall missing. As the wind keeps pouring into the opening, the pressure inside climbs and presses up on the roof from underneath at the same time the wind passing over the top is pulling on it. The house door into the garage takes the same push from the garage side.
Closed, the door makes the garage an enclosed room again, and the wind is back to pushing on the outside of the house.
Once a warning is issued for your area, the door stops being the job, and getting everyone to shelter is.
Will the door come down on its own power, by hand, or not at all?
One of the three, and you can usually tell which from the garage floor in a minute without touching anything that carries tension. A door that still moves under power or by hand gets closed now. A door that will not move gets left where it is.
- On its own power. The opener refuses, but the door hangs square in both tracks and nothing dangles. That is usually the opener protecting itself, and the sensor and wall-button checks for a door that won’t close get most of these down in minutes.
- By hand. The opener is dead from an outage or a failed part, but the door is square and the springs are whole. It comes down under your hands, the way the hand-operation steps for a power outage describe.
- Not at all. The door sits crooked, one side hangs lower than the other on a single cable, or a spring has let go with the door up. This one does not come down before the storm.
The third case is the one people try to talk their way out of. A door stuck up on a broken spring is carrying weight that nothing is balancing, and bringing it down by hand means catching all of it. With weather coming, an open garage is the smaller of the two risks. Leave it, keep everyone and every car out from under it, and spend the time on anything loose the wind could throw around the garage, like bins and ladders, as long as nobody has to walk under the door to reach them.
What if the door only comes partway or hangs crooked in the opening?
Stop pressing the button. A door that came down partway and stopped, or came down crooked, has usually lost a roller from the track or a cable from its drum, and every run after that pulls it further out. With wind on the way, the gusts finish whatever the last press started.
The order that damage arrives in is laid out in the guide to what each extra cycle does to a door hanging on one cable. For this afternoon, the door stays in whatever position it stopped in.
Then clear the floor beneath it. Pull out anything the door could land on, and if the car is already outside, park it well away from the opening rather than back inside. A door that is half on its hardware can drop or swing without warning, and nobody should be walking through the gap under it to reach the house.
Caught at this stage, a crooked door is usually an off-track correction, which the price list puts at $125 to $250, more if panels are creased or a track must be replaced. A gust catching a half-hung door is how the job picks up a creased section.
How do you hold a closed door down when the opener is disconnected?
With the opener disconnected, the door is held shut by its own weight and nothing else, and a door with healthy springs is balanced to lift easily. That is the trouble in a strong gust. Slide the manual lock if the door has one, then clamp each vertical track above a roller so the door cannot rise.
Normally the opener holds the door down, since the trolley on the rail is locked to the top of the door. Pull the release cord for an outage or a dead opener and that hold goes away, leaving a door that a hard push from underneath, or wind working at the bottom seal, can lift a few inches at a time.
The manual lock, where there is one, is a slide bar on the inside of a lower section that shoots into a slot in the track. Plenty of newer doors were built without one. If yours has it, slide it on both sides.
Each vertical track gets a clamp of its own, a C-clamp off the workbench or locking pliers from the toolbox, set on the track an inch or so above one of the middle rollers, at a height you can reach standing on the floor. The roller cannot climb past it, so the door cannot rise. The clamp touches the track and nothing else. Keep hands off the cable running beside the track, the springs and drums over the door, and the brackets at the bottom corners.
The clamps come off before anyone runs the opener or presses the wall button again. An opener driving a door against a clamped track bends the track or strips its own gear, and a piece of tape across the wall button with the word “clamped” on it covers the day the power comes back while you’re at work.
What happens when a gust catches a door that is moving?
A door in the middle of its travel is a broad flat panel riding on small rollers, held at the edges by two thin tracks. A gust hitting it then pushes it sideways or bows it inward, a roller jumps out of the track, and the door ends up cocked in the opening. Run a door in a lull between gusts, in one pass, or leave it where it is.
Wind catching a door partway up is one of the two usual ways a door here ends up crooked in its tracks. A bumper at parking speed is the other.
If the gusts are coming in sets, wait for the quiet stretch, stand where you can see the whole door, and keep a hand near the button so you can stop it if one side starts to lag. If the wind is already steady and hard, a door that is closed stays closed until it passes.
There is a slow version of the same damage. Over years, the wind off Keystone works track bolts and bracket lags loose a little at a time, and a door with a loose track is the one most likely to jump in a gust. The maintenance guide’s section on Keystone wind covers how that happens and what gets checked after a blow.
Why does a storm day stretch the wait for a repair?
Every exposed door on the west side and around the lake meets the same wind in the same few hours, so the calls arrive together. Doors that will not secure go to the front of the line. A door that will not shut is worth calling about before the storm, while the schedule still has room in it.
After the weather passes, a door hanging open or crooked still goes ahead of a dented panel on a door that closes.
Urgent scheduling moves a stuck door up the day, and it does not add a surcharge to the work. The prices are the ones posted for any other day, and what storm repairs cost is on the pricing page. If the wind did the damage, photograph the door from inside and out before anything is moved, since those photos are what a claim starts from.
