Cooper City homes built mostly in the 1960s-70s face specific weather seal wear from mild, humid conditions. Here's what actually goes wrong and when to call.

The Problem
Most houses in this part of Cooper City went up between the 1960s and 1970s, with the broader housing stock here spanning 1953 to 2005 and a median build year around 1972. That means a lot of garages still run the original bottom seal track or a replacement seal that's been baked and softened by decades of sun. The mild temperate climate here doesn't crack seals with freeze-thaw the way a northern town does, but it does something just as damaging over time: constant humidity and steady UV exposure turn PVC and rubber brittle from the inside out, long before the door itself shows any wear. You get a seal that looks intact but has lost its flex, so it stops closing the gap at the corners. Homeowners notice it as a draft along the slab, or as water creeping in during a hard afternoon rain. It's rarely the door failing. It's the strip you can't see going bad while everything else looks fine.
What Most People Get Wrong
The common mistake is treating a draft like an insulation problem when it's usually a seal or threshold problem. People add foam board to the inside of panels or weatherstrip the sides of the frame and skip the bottom seal entirely, which is the part doing the actual work against ground-level moisture and wind-driven rain. On a house from the 1960s-70s stock that's common around here, the slab itself has usually settled a little over fifty-plus years, so the seal that fit when the house was built no longer sits flush against the concrete. Swapping in a same-size replacement seal doesn't fix a gap that's grown; it needs a thicker bulb seal or a track adjustment. Another mistake: assuming a mild climate means seals last indefinitely. They don't age from cold here, they age from sun and humidity, which is a slower failure and easier to miss until the draft is already noticeable indoors.
When to Get Help
Call when you can see daylight at the bottom corners with the door closed, when the seal has hardened enough that it doesn't spring back after you press it, or when water shows up on the garage floor after rain that isn't coming from anywhere else in the space. If the door is original to a house from the 1953-2005 build range and has never had the seal replaced, it's worth having someone check the track and threshold together rather than just the strip, since settling on older slabs changes the fit. One honest limit: if the bottom of the door itself has rusted or warped from years of sitting in a bad seal, no amount of new weatherstripping fixes that, and replacing the panel or the door is the better call at that point.
What Local Conditions Do
The mild temperate band this area sits in means the seals aren't fighting ice, but they are fighting near-constant humidity and regular sun exposure across most of the year, which breaks down rubber and PVC differently than a cold climate does. On the mostly 1960s-70s housing stock common in the area, that steady wear shows up as a seal that's shrunk slightly and pulled away from the frame, not one that's cracked or split the way a freeze cycle would cause. It's a slower kind of failure, which is exactly why it goes unnoticed until someone's standing in the garage during a storm wondering where the water's coming from.
Questions, answered
Why does my garage door let in a draft even though it looks fine?
On homes from the 1960s-70s stock common in Cooper City, the seal often looks intact but has hardened from years of sun and humidity, losing its flex. It stops sealing tight at the corners even though there's no visible crack, which is why it's easy to miss until you actually feel or see the gap.
Does Cooper City's climate cause seal problems the same way cold weather does?
No. The mild temperate climate here doesn't put seals through freeze-thaw cycling, so they don't crack the way they would up north. Instead they break down slower, from steady heat and humidity, which shrinks and stiffens the rubber over years rather than splitting it in one season.
My house was built in the 1960s or 70s. Should I worry about the original seal?
After fifty-plus years, yes, especially if it's never been replaced. Beyond the seal itself, the slab has usually settled a little over that time, so a same-size replacement seal may not close the gap. It's worth having the fit checked, not just the material.
