Richmond homes built between 1938 and 2001 lose heat fast through worn garage door seals. Here's what our cold-moderate climate does to that rubber and when to fix it.

What the Weather Here Does to It
Richmond sits in a cold-moderate climate band, which means the bottom seal on your garage door goes through real freeze-thaw cycling every winter without the deep-freeze extremes that would force everyone to switch to heavier gasket material. That in-between pattern is actually harder on standard vinyl seals than a steady cold would be. The rubber hardens, then softens, then hardens again as temperatures swing, and each cycle opens tiny cracks along the bottom edge. On a lot of the housing stock around here, built between 1938 and 2001 with a median build year of 1977, the original seal track was sized for whatever slab settling had happened by installation day. Fifty years on, in neighborhoods like Windsor Farms, Stratford Hills, and North Side where houses from that era are common, slabs have shifted a bit more, and the gap between the door and the floor isn't uniform anymore. A seal that looks fine standing up can still let a draught through at one corner. You'll notice it as a cold stripe of air near the bottom track, sometimes with a thin line of daylight visible if you're standing outside at dusk.
When to Get Help
Call when you see daylight under the door in more than one spot, when the seal has pulled loose from its track and won't sit flat, or when you feel cold air moving across the garage floor even with the door fully down. On older tracks, especially the ones you'll find on houses from the 1960s and 70s stock that makes up most of this area, the seal channel itself can be worn or bent, and a new seal won't seat right until that channel is straightened or replaced. If the door is original to a house from that era, it's worth having someone look at the whole bottom section, not just the rubber, since the aluminum retainer can be brittle by now.
What Changes with the Season
Fall is when the gap usually gets noticed, because that's when the heat comes on and a drafty garage door starts costing you something you can feel. Seals that stretched a little in summer heat contract again once temperatures drop, and a seal that was borderline in August can pull away from the track entirely by December. Homeowners across the area, whether close in near Church Hill and Manchester or further out toward Mechanicsville and Ashland, deal with the same swing, since it's driven by the regional climate band rather than by anything specific to one side of town. Spring brings the opposite problem: seals that hardened over winter don't spring back to shape right away, so a door can drag or bind on the track for a few weeks before the rubber loosens up again.
The Problem
Here's the honest limitation: a worn seal is a cheap, fast fix, but it doesn't fix a bent track, a settled slab, or a door that's racking slightly on its rollers. If you replace the seal and the draught comes back within a season, the seal was never the actual problem. On the older end of this area's housing stock, doors installed decades ago sometimes have both issues at once, a tired seal and a track that's shifted with the house. Replacing rubber on a track that's out of line is a temporary patch, and we'll tell you that instead of selling you a seal that won't hold.
Questions, answered
Why does my garage door let in a draught even though the seal looks new?
If the seal is new but the track underneath is bent or the slab has settled unevenly, the seal can't seat flat no matter how fresh it is. This shows up more often on houses from Richmond's older stock, where decades of minor slab movement have shifted the gap the seal has to cover.
Is a drafty garage door worse in winter here?
Richmond's cold-moderate climate means seals go through repeated freeze-thaw swings rather than one long deep freeze. That cycling cracks standard vinyl seals faster than steady cold would, which is why a lot of homeowners notice the draught getting worse as fall turns to winter.
Can I just replace the seal myself?
You can, and for a straightforward worn seal on a level track it's a reasonable weekend job. The catch is telling the difference between a seal problem and a track problem, and on older doors those two often show up together.
