Preparing Your Garage Door for a Connecticut Winter

Connecticut gets its worst weather in two forms: nor'easters that push wind and wet snow off the Sound for a day at a time, and the remains of tropical systems that still reach New England in late summer. The garage door is the largest opening in the building for both of them.

Know what your door is rated for

The Connecticut State Building Code sets a design wind speed for every address, and it is not the same everywhere. Towns along Long Island Sound carry higher design pressures than the inland hills, and stretches of the shoreline sit in a wind-borne debris region where the requirements are stricter again. Doors fitted before those requirements tightened are common here, and plenty of them are not rated for the wind speed their address now assumes.

Look for a label inside the door, usually on a section or the track, stating the design pressure. If there is no label, assume it is unrated until proven otherwise.

If you do one thing before the storm season, find out whether your door is rated. Everything else on the list is maintenance — that one is structural.

Before the weather turns

Bracing kits

If your door is structurally sound but under-rated, a retrofit bracing kit is a legitimate option and far cheaper than replacement. It must be a kit designed and approved for your door — timber propped against the inside is not bracing and does not work.

After the storm

Even if the door still opens, look along the top edge of each section for buckling, check the track for kinks and the cables for slack. Clear drifted snow and ice away from the base before you cycle it at all — lifting against a frozen seal is how a storm that did no damage ends up costing you an opener. Wind damage is often invisible until the door is next cycled, and that first cycle is where hidden damage becomes real damage.

Why the garage door is the one that matters

Ask a structural engineer which opening fails first in a storm and the garage door comes up immediately. It is the largest single opening in most houses and the least reinforced.

The failure mode is what makes it serious. Once the door goes, wind is inside the building, and pressure starts working against the roof structure from underneath rather than pressing down on it. A door problem becomes a roof problem quickly, which is why the rating on the door is worth knowing before the weather arrives.

Finding out what yours is rated for

There should be a label inside the door, usually on one of the sections or on the track. It states a design pressure: how much positive and negative pressure the assembly is built to take.

Positive is wind pushing the door inwards. Negative is suction pulling it outwards, and suction is what usually takes a door — which is why bracing that only resists inward push is not enough on its own. If there is no label anywhere on the door, treat it as unrated until somebody demonstrates otherwise.

Our pre-season checklist

Worth doing before the cold rather than during it:

• Tighten every track bracket, hinge and lag bolt. A year of vibration loosens them and winter finds the loose ones.
• Lubricate with a light lithium or silicone spray — heavy grease stiffens in the cold and makes the door drag.
• Check the bottom seal is soft and sitting flat, so it is less likely to freeze to the slab.
• Clean both photo-eye lenses and check alignment before snow starts getting shovelled near them.
• Confirm the opener has a battery backup, or work out now how you will open the door without power.

The two visits a year that matter

We suggest servicing twice here rather than annually, and the timing is the point. Once before the cold so the door is not fighting stiff grease and a tight track through the worst of it. Once after, to get the winter's road salt off the bottom section before it sits there through the summer quietly eating the steel. Miss the second one and you pay for it in about three years.

Where rust starts, and why it matters

Always the bottom. The lowest section, the bottom brackets, the base of the track and the bottom rollers — because that is where road salt, meltwater and grit all end up sitting together.

Rinsing the bottom two feet of the door on a mild day in March is a genuinely worthwhile ten minutes. It is the cheapest maintenance there is, and almost nobody does it.

The DIY job that goes wrong most

Anything involving springs or cables. They hold the entire weight of the door under tension, and they are the two parts most likely to fail. Lubrication, cleaning the sensors and tightening bolts are all perfectly reasonable to do yourself. The parts carrying the load are not.

A last thought

Garage doors are unusual in that almost every failure announces itself first. Very little about them is genuinely sudden; it only looks that way because the warnings are easy to live with.

Paying attention to the small changes is what keeps a door out of the emergency queue.
