Reston homes built from the 1940s through 2015 lose track alignment for reasons tied to age and our cold winters. Here's what actually causes it and what to expect.

What Is Going On
A door goes off track when the rollers stop riding true inside the vertical or horizontal rail. Sometimes it's one roller popped loose after a cable snapped or a spring let go unevenly. Sometimes the track itself has pulled away from the jamb because the mounting brackets worked loose over the years.
That second cause shows up a lot in this area. Housing here runs from 1940 through 2015, with most of it dating to the 1980s and 90s. Doors installed in that stretch typically used lighter steel brackets, fastened straight into wood jambs with lag screws rather than the heavier hardware and reinforced framing that's become standard since. After a few decades of the door opening and closing, those screws back out a little at a time. You don't notice until the track has enough play that a roller jumps the rail on a hard stop.
We also see it on doors where one side's track sits slightly out of plumb from the original build. It doesn't cause trouble for years, then a cold snap or a slammed door pushes it past the point where the rollers can compensate. At that point the door is off track, not just misaligned, and it needs to come back on the rail before anything else gets fixed.
What Changes with the Season
The mounting hardware in a house built in the 1980s or 90s wasn't designed with today's insulated, heavier doors in mind. Add a winter freeze-thaw cycle and those original lag screws see more stress than they were sized for. We get more off-track calls from late fall into early spring than any other stretch of the year, and it's almost always the same story: brackets that were already a little loose finally let go once the wood around the screws contracts in the cold.
Spring and summer bring a different pattern. Humidity swells the wood jamb slightly, which can actually mask a loose bracket for months until the wood dries back out in fall and the play returns. If your door has felt slightly off since last winter and seemed fine over summer, that's not a coincidence, it's the same loose hardware, temporarily hidden.
What the Weather Here Does to It
Reston sits in a cold, moderate climate band, not the deep-freeze conditions you'd get further north, but enough temperature swing through the winter to matter for a garage door. Steel track contracts in the cold and expands again once temperatures climb back above freezing during the day. Over a winter with several freeze-thaw cycles, that repeated movement is exactly what backs out fasteners in older mounting brackets.
Moisture is the other half of it. Rollers and hinges that sit near an unheated garage door pick up condensation on cold mornings, and rust starts on the roller stems long before it's visible on the track itself. A rusted roller doesn't roll true, and a roller that doesn't roll true is a roller that eventually walks off the rail. Neither of these is dramatic on its own. It's the accumulation over a house's lifetime, especially one built decades ago, that turns a minor issue into a door that's fully derailed.
What It Costs
We don't have a set number to hand you here, because what an off-track repair runs depends on whether it's just a bent track section, a full bracket replacement, or a door that's come off far enough to have damaged a panel on the way down. What we can tell you honestly: if the track and brackets are original to a house built well before 2015, we're often better off replacing that section rather than patching it, since matching decades-old hardware gets harder every year.
One limitation worth saying plainly, if the door has been forced back onto a bent track more than once, the metal has usually fatigued to the point where a straightened track won't hold alignment for long. In that case we'll tell you to replace it rather than take a repair fee for something that's going to come back off in a season or two.
Questions, answered
Why did my garage door come off track after the cold snap?
Cold makes steel track contract, and in houses built decades ago the mounting brackets were fastened with lighter hardware than what's used today. Years of that seasonal contraction back the screws out a little at a time. A hard freeze-thaw stretch is often what finally lets a loose bracket give way.
Can I push the door back onto the track myself?
We'd rather you didn't. A door under spring tension that's off track can drop suddenly, and forcing it back on without releasing that tension first is how fingers and panels get hurt. Call it in and leave the tension work to someone who does it daily.
Is an off-track door always a track problem?
No. Sometimes the track is fine and the real cause is a broken cable or an uneven spring that let one side of the door drop faster than the other, pulling a roller off the rail. We check the whole system, not just the track, before we say what actually failed.
My house is older, should I expect this again?
If your house dates to the main building years around here, the 1980s and 90s, and the track hardware is original, it's worth having it checked rather than waiting for a second off-track call. Replacing worn brackets once is usually cheaper than repeated repairs.
