What It Costs
We're not going to throw a number at you here, because we don't have pricing data to back one up for this page. What we can tell you is what drives the cost when a seal job turns into something bigger. A straight bottom-seal swap on a door from the 1980s or 90s stock that makes up most of this area is a small job. It gets bigger fast if the track has rusted out of square, if the threshold underneath has settled, or if the door panel itself has warped enough that no seal will sit flat against it anymore. Houses here built between 1968 and 2000 (median around 1989, per F1) are old enough now that the original hardware and the replacement seal don't always match up cleanly. That mismatch is where a simple swap becomes a track adjustment or a panel look-over. Ask for a number after someone's looked at your actual door, not before. A phone quote on a seal job is a guess, and we'd rather tell you that than make one up.
What the Weather Here Does to It
This area sits in a cold, moderate climate band, not the deep-freeze kind but enough seasonal temperature swing to work rubber seals loose over years, not months. Vinyl and rubber bottom seals shrink slightly every time the temperature drops, and they don't fully spring back each spring. On a door installed in the 1980s or 90s, which describes most of the garage doors in the 33 named communities that make up this service area, that seal has gone through three decades of that cycle. The result isn't usually a dramatic failure. It's a slow gap that opens at one corner first, then along the whole bottom edge, letting in a cold draught that shows up as a chilly spot near the garage-side door or a noticeably colder mudroom. Side seals and the top seal along the header go the same way, just slower, because they take less direct weather. None of this means the door is broken. It means the rubber has done what rubber does after 30-plus years of a Pacific Northwest cold season, and it's due for replacement, not repair.
What to Look at First
Start at the bottom. Kneel down and look at the rubber seal where it meets the concrete along the whole width of the door, not just the middle. On the older doors common to this area's 1980s-90s stock, the corners give out first because that's where the seal flexes the most every time the door cycles. If you can see daylight, or slide a finger under it without resistance, that seal is done. Next, check the vertical seals on both sides of the door where it meets the frame, they're often brush-style or foam strip rather than the rubber bulb type, and foam degrades faster in a cold-swing climate. Then look at the threshold, the raised strip on the floor if your door has one, for gaps at the ends. Last, check the track brackets for surface rust, since a house from this build era has often had one or two rounds of moisture sit in that corner over the years. If the seal looks fine but the draught is still there, the leak is probably at the frame, not the door.
The Situation
Most of the garage doors we look at around here trace back to the same building wave, houses put up between 1968 and 2000 with the bulk clustered in the 80s and 90s, spread across the string of communities from here out toward Machias, Lochsloy, Snohomish, and Granite Falls. That means a lot of doors are hitting the age where seals, not springs or openers, are the first thing to go. A worn seal is a cheap, boring problem compared to a broken spring, which is good news, but it's easy to ignore because it doesn't stop the door from opening. It just costs you heat and lets moisture creep in around the edges. If your door is from that same build era and you're feeling a draught, the seal is the first suspect, not the motor. We'd rather walk you through checking it yourself first than send a truck out for a five-dollar part.
Questions, answered
How do I know if it's the seal or the door itself letting in cold air?
Check the seal edges first: if the rubber is cracked, flat, or pulled away from the door, that's your draught. If the seal looks intact but you still feel air, the problem is more likely a warped panel or an out-of-square track, which is a different repair.
Do all garage doors in this area have the same seal problem?
Not all, but a lot of them share the same age. Most housing here went up between 1968 and 2000, with the bulk in the 1980s and 90s, so a large share of doors are hitting the point where original or first-replacement seals have shrunk from years of seasonal temperature swing.
Can I replace a bottom seal myself?
Often yes, if the track is straight and the panel isn't warped. It's a low-risk job on most standard doors. Where it gets tricky is matching the seal profile to older hardware from this build era, since some of it doesn't match what's sold in stores today.
Is a draughty garage door worth fixing or should I replace the whole door?
For a seal alone, fix it, it's cheap and doesn't justify a full replacement. Replacement makes more sense if the panel is warped, the track is rusted out, or you're already dealing with a second issue like a failing spring on the same door.
