A Houston Garage Door Maintenance Calendar

A garage door maintenance schedule written for a national audience tells you to service the door in spring and autumn. That is not wrong, and it is not useful here either. Houston does not have a spring and an autumn in the sense that advice assumes — it has a humid season, a storm season, and a short, mild window in between when it is genuinely pleasant to work in a garage.

So this calendar is built on what actually changes in this climate: the humidity that keeps metal wet for most of the day, the storm season that puts real pressure on the largest opening in the house, and the periods when neither is happening and the work is easy. Hurricane season garage door preparation is the one item on it with a deadline, which is why it sits in May rather than in the week a storm gets a name.

One honest note before the calendar itself. You will find Houston maintenance articles that claim springs fail most in a particular month, with a chart. We are not publishing one. We do not have a call dataset that would support a monthly failure curve, no manufacturer or standards body publishes one, and a chart invented to fill the space would be worse than no chart.

The garage door maintenance schedule, season by season

Hurricane season garage door preparation: the May list

Atlantic hurricane season runs from 1 June to 30 November. The preparation is done before it opens, because the things worth checking cannot be checked in a hurry and the parts cannot be bought once a storm is in the Gulf.

Why the door specifically: it is the largest opening in a house, and FEMA's assessment team after Hurricane Harvey found that "many sectional garage doors that were not rated for high winds … failed during Hurricane Harvey," while "very few hurricane-rated sectional doors were observed to have failed" (FEMA P-2054). IBHS describes the mechanism in the same terms the field evidence does — weak tracks buckle, debris pierces a panel, and inadequate attachment lets the door detach and fail inward (IBHS).

The May list, in order:

1. Read the label on the door. A door tested to the current standard carries a permanent label giving the manufacturer, the model or series, the positive and negative design pressure rating, the installation drawing reference and the test standard (2021 IRC R609.4 and R609.4.1). If there is no label, or it was painted over, you do not know what the door is rated for — and an unlabelled door is the one that fails first in the field data.
2. Look at how the track is fixed to the building. Not the track itself — the attachment. IBHS names inadequate attachment as a failure mode, and DASMA publishes the connection guidance for jamb-to-framing in TDS 161. Loose jamb brackets and missing bolts are a May problem, not an August one.
3. Check the hardware that carries the wind load. A door's rating is achieved by the whole assembly, and the installer has to quote the correct track, the correct number of rollers and the correct struts to reach the design pressure (IBHS FORTIFIED bulletin 2015-03). Missing struts or substituted rollers quietly remove that rating.
4. Check the bottom seal and the panel edges. A torn seal lets driven rain in under the door, and the bottom section is where water sits afterwards.
5. Test the opener's reversal and the photo-eye. In a storm you may be closing the door with the power flickering, and this is not the day to discover the sensors are intermittent.
6. Decide the procedure. If a storm is coming, the door's job is to stay shut and stay whole. DASMA's guidance for doors in saline coastal and extreme-heat climates is to keep them closed where possible (DASMA TDS 190), and closing it also keeps the wind out of the building in the hours before landfall.

The humid months: what Houston air does to the hardware

This is the part of the calendar most national advice gets wrong, usually by overstating it. Houston's 24-hour mean relative humidity is around 65%, not the 75–90% you will read almost everywhere — the overnight and early-morning figure in July and August is close to 89% on the 1991–2020 NOAA hourly normals, and the daily mean is roughly two-thirds of that headline range. The honest version is still bad for metal: the day does not dry out much before the next night begins, and the Port of Houston Authority's corrosion manual notes that year-round relative humidity above 70% means surfaces dry slowly (Port Houston corrosion manual).

The corrosion case rests on that dwell time, not on the daily average. Chloride salts pull moisture out of the air, the surface stays wet, and the drying that would stop the reaction is slow. For a spring, the consequence is documented by the industry's own standards body: rust reduces the effective area of the wire, and corrosion pits become the places where fatigue cracks start (DASMA TDS 190).

What to do about it in June, July and August:

• Look for rust where it starts: orange staining or red-brown dust under the spring, discolouration at hinge pins and roller stems, cable ends, and the bottom bracket. Surface rust on a painted panel is cosmetic; pitting on a spring is not.
• Lubricate per the owner's manual, not more often. ANSI/DASMA 102-2018 §8.6 states that lubrication "shall not be done more frequently than once every 1500 cycles." More oil is not better — it collects grit.
• Keep the door closed where you can, which is the standards body's advice for humid, saline and extreme-heat climates and also keeps the garage cooler.
• Do not hose down the springs. Rinsing road salt and dust off the panels is fine; the spring guidance is that springs should be kept dry.

After a storm: what to check before you touch anything

The first action after any high wind or flood event is nothing. Do not press the button to see whether the door still works. A door that has been loaded by wind may be intact at rest and fail the moment it moves, and a door that has taken water has a different problem underneath it.

Then, from the ground, without putting a hand near a spring or a cable:

• Panels: dents, punctures, cracks at the section interfaces, or a bottom section that has taken on water.
• Track: bent sections, joints out of line, jamb brackets pulled away from the framing, or bolts that have sheared.
• Rollers: any roller out of the track, or a track that has spread enough to let one out.
• Cables: slack, kinked, off the drum, or frayed. None of these are do-it-yourself items.
• Bottom seal and the slab: standing water, debris, or a seal that has lifted.
• The opener: a case that has taken water, or a light that behaves oddly.

If the door took in floodwater, expect the damage to be concentrated at the bottom of the door. A published NFIP appeal decision on exactly this shows the insurer paying to replace "the lower panel of the garage door, weather stop, insulation kit, and labor for the repair" after four inches of water inside an attached garage (FEMA/NFIP decision). Photograph everything before it is cleaned up, because that is what a claim is decided on.

DASMA's post-event guidance for rolling doors is the standard to borrow here: "an event such as high wind, seismic, or flooding should require an immediate evaluation of all door systems in the facility regardless of when the last periodic inspection was performed" (DASMA TDS 270). That sentence is written for commercial rolling doors. The logic transfers to a house, and it is why the inspection below happens after every named storm rather than only at the next scheduled visit.

What genuinely waits for a professional

Some of this list is a habit. Some of it is not yours to do at all, and it is worth separating the two before anyone picks up a wrench.

That last row matters. There is no Houston ordinance and no Texas statute that makes an annual residential garage door inspection mandatory, and any company that tells you otherwise is selling with a false premise. The obligation you do have is to follow the door's own documentation, and to leave the torsion spring, the winding cones, the cables and the bottom bracket to a technician — those parts store enough energy to injure or kill someone who loses control of them. If a part on that list is what your inspection turns up, stop and book it rather than reading further.
