Greenville, SC · Garage Door Service
See why doors in older Greenville homes near Wade Hampton and Dunean lose seals faster, and what actually stops draughts through your garage in cold snaps.
Half of the houses standing in and around Greenville went up before 1981, the median year in our housing count, and the oldest stock on record dates back to 1938. A door that old has usually had its weatherstripping replaced once, maybe twice, by whoever owned the place before you - and not always with the right profile. What you feel as a draught along the bottom of the door, or a cold line across the concrete on a January morning, is almost always a seal that's shrunk, cracked, or was never sized for that jamb in the first place. This isn't a dramatic failure. It's slow, and most owners live with it for years before they call anyone. The fix is rarely the whole door. It's usually the strip of rubber or vinyl running along the bottom edge, the two side jambs, and sometimes the top header seal, all of which age at different rates depending on which way the door faces and how much sun it gets. On a house built in the early 1980s, which describes a lot of this area, that's forty-plus years of seasonal expansion and contraction on whatever seal is currently in there.
Start at the bottom. Kneel down with the door closed and look for daylight along the threshold - that's the single most common leak point, and on older slabs the concrete itself has often settled unevenly, leaving a gap on one side even when the seal looks fine. Next, run a hand along both side jambs where the door meets the frame; if the vinyl feels stiff or has pulled away from the track, it's not sealing anything, it's just decoration at this point. Check the top seal where the header meets the door - this one gets ignored because you can't see it without a ladder, but it's often the worst offender on doors that face west. Last, look at the panel joints themselves if you've got an older sectional door; on units from the 1980s and 90s a stretched or torn joint seal lets air through every seam, not just the edges. None of this requires tools, just a flashlight and ten minutes. If you find gaps at more than two of these points, you're not chasing one bad seal, you're looking at a full weatherstrip job.
Greenville sits in a moderate cold climate band - not the hard freeze-thaw cycling you'd get further into the mountains, but enough swing between humid summers and cold snaps in winter to work ordinary vinyl seals loose faster than you'd expect. That back-and-forth is what actually breaks a seal down: it's not one hard freeze, it's the seal expanding in July heat and contracting in a January cold snap, year after year, until it loses its memory and stops springing back against the jamb. Houses in the neighborhoods closer in - Wade Hampton, Dunean, Gantt, Sans Souci, all within four or five miles - carry stock mostly from the 1980s and 90s expansion, which means original seals installed during a building boom, not necessarily matched to the specific door or track that ended up on the house. Out toward Travelers Rest and Piedmont, ten and eleven miles out, some of the older housing still runs track spacing that predates today's standard seal kits, which changes what fits without shimming. That's a detail worth checking before you buy a seal off a shelf and find it's a half-inch short.
The biggest mistake is treating a draughty door as a reason to replace the whole unit. Most of the time it isn't - it's a seal job, and a seal job is a fraction of the cost of a new door. The second mistake is buying a universal seal kit without checking the jamb profile first. A door built anywhere between 1938 and 2013 in this area could be sitting on any of three different jamb designs, and a seal that doesn't match the channel width just sits there loose, which looks fixed but still leaks. Here's the honest limit: we don't carry every track and jamb profile on the truck for a same-day fix, so a door with an unusual or older profile sometimes means a short wait on the right part rather than a quick patch that won't hold. It's worth doing right the first time rather than replacing the same strip of vinyl every winter. If your door is genuinely at the end of its life - warped panels, rusted track, a frame that's pulled away from the house - a seal won't fix that, and we'll tell you so instead of selling you rubber.
Close the door and check for daylight or airflow at the bottom threshold, both side jambs, and the top header. If light or air comes through at those specific lines, it's almost always the seal. If the door itself is warped, sagging, or won't sit flush in the frame no matter what, that's a structural issue a new seal won't solve.
No. Track and jamb profiles vary, especially across housing built from the late 1930s through the 2010s in this area. A kit sized for one profile can leave a gap on another. It's worth checking the jamb shape before buying, rather than returning a kit that doesn't seat.
The moderate cold swings here - hot, humid summers into cold winter snaps - cause vinyl and rubber seals to expand and contract repeatedly. Over years that cycle breaks down the material's ability to spring back against the jamb, which is why seals on older homes in this area often need replacing well before the door itself does.
Possibly. A lot of housing across this area, including neighborhoods like Wade Hampton and Sans Souci, was built during the 1980s and 90s push. If nobody's mentioned replacing the weatherstripping since you've owned it, there's a real chance it's original, and original vinyl from that era is well past its useful life.
