A customer called last Tuesday asking why her garage felt like a walk-in freezer despite the heater running. After a quick inspection, I found the culprit: a worn bottom seal letting cold air pour in from underneath the door. Weather stripping and seals are one of the easiest.and most overlooked.ways to keep your garage comfortable and your energy bills reasonable.
New Hampshire winters are no joke. Temperatures in Springfield regularly dip below zero, and that's when a failing seal becomes impossible to ignore. Weather stripping creates an airtight barrier around your garage door, blocking drafts that let heat escape and cold creep in.
Here's what most homeowners don't realize: a compromised seal doesn't just affect comfort. It drives up heating costs, can damage stored items, and sometimes signals larger structural issues with the door itself. The bottom seal takes the most punishment.it's constantly flexing, cracking, and compressing from years of temperature swings and daily use.
Look for these red flags around your garage door:
- Visible cracks or tears in the rubber seal material - Light streaming under the door or around its edges - Cold drafts you can feel when standing nearby - Water pooling inside after rain or snow melt - Daylight visible through gaps at the threshold
If you've noticed any of these, don't wait. A deteriorating seal only gets worse, and the cost to replace weather stripping now is a fraction of the heating bill you'll pay if you delay.
The bottom seal is the workhorse. It bears weight, flexes constantly, and endures direct contact with pavement, snow, and road salt. We typically recommend a heavy-duty rubber threshold seal that lasts 5,7 years with proper maintenance.
Side and top seals are equally important. These prevent air leakage around the door frame and keep pests out. Many Springfield homeowners don't realize they have gaps here until their first winter utility bill arrives.

Some homeowners attempt to replace seals themselves. It's possible, but there's a catch: improper installation creates new problems. If the seal isn't compressed evenly, drafts persist. If you over-tighten, the door won't close smoothly.
We've had customers from nearby towns like Lebanon come to us after a DIY attempt went sideways. Professional installation takes about an hour and guarantees the seal is fitted correctly the first time. We also handle the disposal of old materials properly.
Seals work best as part of a broader maintenance routine. If your springs are failing or your door is misaligned, a new seal won't solve everything. During our inspections, we check the whole system.tracks, hinges, springs, and seals.to identify any issues.
Similarly, if you're preparing for storm season, seals are essential but just one piece of the puzzle. We've written a detailed guide on preparing your garage door for storm season that covers seals alongside other critical protections.

Don't let another winter pass with a drafty garage. A few hundred dollars in seals now saves you hundreds on heating costs and protects your stored items from temperature swings.

How long do garage door seals last? Heavy-duty rubber seals typically last 5,7 years in New Hampshire's climate. Extreme temperature swings and road salt accelerate wear, so inspect annually and replace when you see cracks or gaps.
Can I replace just the bottom seal, or do I need all three sides done? You can replace seals individually, but we recommend replacing all three if any are compromised. A weak side or top seal lets drafts in regardless of the bottom condition, and the labor cost is nearly the same.
Will new seals alone lower my heating bill? If drafts are your primary issue, yes.noticeably. Most homeowners see a 10,15% reduction in winter heating costs after seal replacement, though results depend on your door's overall condition and your home's insulation.
