Why Garage Doors Across Atlanta Let In Draughts
Why weather seals and draughts show up on Atlanta garage doors built between 1951 and 2004, how cold-moderate winters wear the rubber, and what actually needs fixing first.
Local detail
Leaving It Alone
Not every draught needs a truck rolling out. If the gap under your door is thin and even, and you're not seeing daylight in more than one or two spots along the bottom, the seal is doing its job and just needs a look next season. A lot of the housing stock in this service area went up between 1951 and 2004, with most of it concentrated in the 1960s and '70s build boom, and doors from that era were built with enough tolerance that a small amount of draught at the threshold is normal, not a failure.
Spending money on a full seal replacement for a gap you can barely feel with your hand is money you didn't need to spend. Where it does matter: if the draught is strong enough to move a hanging cobweb, or you can see a line of light under the door at midday, that's worn material, not tolerance. That's the point where leaving it alone stops being the smart call and starts being the expensive one, because water and cold air behind a weak seal work on the door bottom and the track ends faster than people expect.
The area
What Local Conditions Do
This area sits in a cold-moderate climate band. That doesn't mean brutal winters, but it does mean the seal on your door goes through real freeze-thaw cycling every year rather than sitting at one steady temperature. Rubber compresses in the cold and softens when it warms back up, and that repeated flex is what breaks it down faster than sun exposure alone would. A door in a climate that just stays hot loses its seal to UV cracking; here, the seal loses its shape from the cycling first, and the cracking follows.
That matters for timing: if your door was resealed more than a few years back, the material has already been through several winters of that flex, whether or not it looks obviously worn from the driveway. It also means a seal that tests fine in July can be letting draughts through by January, because the gap changes with the temperature, not just with age. Anyone checking their door for winter should press a hand along the full bottom edge on a cold morning, not a warm afternoon, since that's when a marginal seal actually opens up.
What we find
What Is Going On
Most of the housing across this service area, from Grove Park two miles out to Stone Mountain fifteen miles away, sits on the same building-boom stock: put up between 1951 and 2004, with the heaviest concentration from the 1960s and '70s. That matters for seals because doors from that era were fitted with a bottom astragal and side seals sized to specs that have shifted since. When the original rubber finally gives out, a lot of homeowners find the replacement seal doesn't sit flush against the track the way the factory piece did, because the track itself has worn or shifted slightly over five or six decades.
That's not a defect in the new seal - it's the accumulated wear of an old track meeting new rubber. The draught you're feeling is often less about the seal itself and more about the gap between an aging track profile and a modern replacement part. Fixing it right usually means checking track alignment before you swap the seal, not just pressing a new strip into the same worn channel and hoping it seats.
How we work
The Common Mistake
The mistake we see most is caulking or foam-sealing the gap instead of replacing the worn rubber underneath it. It looks like a fix for a season, then the caulk cracks with the same freeze-thaw cycling that broke the original seal, and you're left scraping it off before the real repair. The other common one, on the opposite end, is replacing the whole door over a draught problem that a $30 to $50 seal would have solved.
With a median household income of $63,449 across this service area, that's a real difference in what a homeowner should spend, and it's worth being honest about: most draught complaints on a door from this housing stock are a seal and track alignment issue, not a structural one. We don't push full door replacement unless the panel itself is warped or the track is bent beyond adjustment - a seal job is a fraction of the cost and solves the actual problem most of the time.
Questions
Common questions
How often should I replace the weather seal on my garage door in Atlanta?
There's no fixed schedule that fits every door, but with the freeze-thaw cycling typical of this climate band, rubber bottom seals on older doors from the 1960s-70s building stock often need replacing every few years rather than every decade. Check it on a cold morning by hand - if you feel air moving along the bottom edge, it's due.
Why does my new seal still let in a draught?
On older houses in this area, the track the seal sits against has often worn or shifted slightly over the decades. A new seal pressed into a worn track won't seat flush even if it's the right size. The fix is usually adjusting or shimming the track before the seal, not buying a thicker strip.
Is a draughty garage door worth fixing or should I replace the whole door?
For most homes on this area's housing stock, the draught is a seal and track issue, not a reason to replace the door. A full replacement makes sense if the panel is warped or the track is bent beyond adjustment - otherwise a seal job costs a fraction of a new door and solves it.
