Weather Seals and Draughts in Boca Raton Garage Doors
Boca Raton homes built between 1968 and 2005 lose seal integrity differently than newer builds. Here's what to check first and what it actually costs to fix.

What Is Going On
Most of the garage doors we look at in Boca Raton sit in openings framed sometime between 1968 and 2005, with the bulk of that stock dating to the mid-1970s. That's a long run of construction standards, and it shows up as inconsistent bottom seal tracks and jamb weatherstrip channels from one block to the next. A door that draughts along the bottom edge isn't usually a sign the door itself has failed - it's more often the original seal material, now decades past its service life, sitting in a track that was never resized when the seal was last replaced.
On the older end of that build range, some openings were framed slightly out of square by today's standard, which means a stock replacement seal can look right and still leave a gap at one corner. We see this most on doors nobody has touched since they were hung. The seal degrades, the homeowner notices air movement or a strip of daylight at the threshold, and assumes the door needs replacing when it's the gasket doing the failing, not the panel or the track.
What to Look At First
Start at the bottom seal - the vinyl or rubber strip running the width of the door where it meets the slab. On a house from the 1970s-80s range typical of this area, that seal is usually the first thing to go brittle and crack, especially where it's held on with an aluminum retainer that's also aged out. Next, check the stop molding along both jambs and across the top; on older openings this is often original wood trim that's warped slightly over the years, which opens a draught line even with a new seal installed.
Run your hand along the door on a breezy day and feel for air movement at the corners specifically - that's where seal and framing tolerance problems show up together. If the door has a garage-to-house entry, check that seal too; it's frequently forgotten and just as often the actual source of drafts owners blame on the big door. We won't sell you a full weatherstrip kit if the bottom seal alone solves it - that's the honest fix in most of these cases.
How Local Conditions Play In
Boca Raton sits in a mild temperate band, so we're not dealing with the freeze-thaw cycling that cracks seals in northern climates. What we do get is steady humidity and repeated expansion-contraction from heat, which breaks down vinyl and rubber seals through UV and moisture exposure rather than cold. That means seal failure here tends to happen from the material drying out and shrinking rather than splitting from ice.
It also means a draught you notice isn't likely storm damage - it's more often just seal age catching up with a mild but relentless climate. Because the temperature swings are gentler than in much of the country, seals in this area can actually last longer than the manufacturer's stated life if the track and framing are sound, which is one more reason to check the seal itself before assuming the whole door assembly needs work.
What It Costs
We don't have a set price to quote here without seeing the door, the seal type, and how much of the track or stop molding needs replacing alongside it. What we can say: a straightforward bottom seal swap is a smaller job than most homeowners expect, and it's rarely worth replacing an entire door over a draught problem alone.
If the framing itself is out of square - more common on the older end of the 1968-2005 range - the fix takes longer because the stop molding needs adjusting to match, not just the seal. We'll tell you upfront if what you're describing sounds like a seal job versus something bigger, and we won't run a full weatherstrip replacement if the bottom seal alone closes the gap.

Why does my garage door let in a draught even though it looks fine?
The seal at the bottom edge is likely brittle or shrunk, which is common on doors that haven't had that strip replaced since the house was built. In Boca Raton's climate, seals degrade from heat and UV rather than cracking from cold, so the door can look undamaged while the seal itself has failed.
Is a draught a sign I need a new garage door?
Usually not. In most of the homes we see, built in the 1968-2005 range, the door and track are structurally fine and the draught traces to a worn bottom seal or aged stop molding. A full door replacement is rarely the right first move for an air leak alone.
Does Boca Raton's climate make weatherstripping wear out faster?
It wears differently, not necessarily faster. Mild temperate conditions mean less freeze-thaw stress, but steady heat and humidity still break down seal material over time through drying and UV exposure, which is the more common failure pattern we see here.
