Why Garage Doors in The Colony Let the Draught In

Local detail

Where People Go Wrong

The usual mistake is treating a draught at the bottom of the door as a caulking problem. It isn't, most of the time. Housing in this area went up between 1973 and 2014, with the median build landing around 2002, so a huge share of the doors we look at still carry the original factory bottom seal that came with the opener and track package the builder spec'd twenty-plus years ago. That PVC strip was never meant to last the life of the house. Owners caulk the slab edge, add a door sweep, even stuff a towel under the gap during a cold snap, and the draught comes right back because the seal itself has shrunk and pulled away from the track, not because the slab moved. Another pattern: people replace the seal once and assume that's the end of it. On a 2000s-era aluminum track, a seal that's been baking and cooling for two decades usually means the retainer channel has also widened slightly, so a stock replacement strip sits loose and still lets air through at the corners. You have to check the channel, not just swap the rubber.

The area

How Local Conditions Play In

The Colony sits in a climate band federal sources classify as moderate heat, not the harshest in the state, but still enough summer expansion and winter contraction to work PVC and rubber seals harder than a mild climate would. That cycling is the main reason seals on homes from this build era - most of the stock across the area's named neighborhoods dates to the early 2000s - tend to crack and stiffen on the sun-facing side of a garage before anywhere else. A west-facing door bakes through the afternoon and then cools overnight, and the seal flexes through that swing every single day for years. On slab-on-grade construction, which is standard for the 1973-2014 housing stock here, there's also less give at the slab edge than a raised foundation gives you, so even a slightly shrunk seal shows up as a visible gap rather than a hidden one. None of this is dramatic weather - no named storm needed. It's just steady thermal cycling doing its job on a strip of rubber that was installed once and never looked at again.

What we find

Doing Nothing For Now

Here's the honest part: a draught alone doesn't mean you need a new door, and it often doesn't even mean you need a new opener or track. If the seal is just dried and cracked but the track alignment is still true, a replacement bottom seal is a straightforward fix and not something we'd pad into a bigger job. Where it stops being a DIY afternoon is when the retainer channel itself has widened or warped - common enough on doors from the 1973-2014 building era once they hit the twenty-year mark - because then a stock seal won't seat right no matter how many times you reinstall it, and you're looking at a channel or full bottom panel replacement instead. We also won't tell you to replace a door that's structurally fine just because the seal failed; that's spray-foam-level overkill for a $20 part, most of the time. The limitation worth knowing: seal profiles vary by track manufacturer, and matching the exact retainer shape from an early-2000s build sometimes takes an extra order rather than something off the shelf same-day.

How we work

The Situation

Across this service area there are roughly 82,997 households and 55,113 owner-occupied houses, the bulk of them built in that same 1973-2014 window with the center of gravity around 2002. That's a lot of garages built the same decade, with the same seal material, hitting the same failure point around now. Median household income here runs about $153,263, which means most owners we talk to aren't looking to nurse a cracked seal along with tape - they'd rather fix it right once, including the retainer channel if that's what's actually worn. The practical upshot for The Colony specifically: if your house falls into that common build era, a draught at the bottom of the door is less a mystery and more a predictable maintenance item that a lot of your neighbors are dealing with at the same time. We work within this area and don't claim reach beyond it.
