Weather Stripping & Seals in Saint Paul: Why Gaps Let In Cold and How to Fix Them
7 min read A2Z Garage Doors
In our years serving Saint Paul, we've seen this problem again and again: homeowners ignore small gaps around their garage door, then winter arrives and they're heating the outdoors. Weather stripping and seals fail silently. Drafts creep in. Your heating bill climbs. Mice find their way inside. The fix is straightforward, but delay turns a $200 repair into much bigger headaches.
What Weather Stripping and Seals Actually Do
Your garage door sits in a frame, and that frame needs protection where the door meets the opening. Weather stripping runs along the sides and top. The bottom seal (sometimes called a threshold seal or weatherseal) sits at the base where your door closes against the ground.
These aren't luxury upgrades. They're barriers. They stop cold air, rain, insects, and rodents from entering your garage and the attached spaces beyond. In Saint Paul's climate, where winters drop below freezing and rain is frequent, a damaged seal isn't just uncomfortable. It can lead to water damage inside your garage, frozen pipes in adjoining spaces, or a full pest infestation.
Most weather stripping lasts 3 to 5 years before it becomes brittle or separates from the frame. The bottom seal wears faster, sometimes needing replacement every 2 to 3 years, especially if your driveway sees heavy use.
Signs Your Weather Stripping Needs Replacement
Look for these red flags right now. Light visible around the edges of a closed door means the seal isn't tight. Cold air flowing in on a still day signals a gap. Water pooling inside after rain, or frost building up on the bottom threshold, tells you the bottom seal has failed.
You might also notice drafts coming from your garage into your home, or find cobwebs, dead insects, or droppings near the door frame. Rodents take advantage of even tiny openings. If you've had one mouse in your garage, a failing bottom seal likely invited it.
Some homeowners also report higher utility bills or rooms next to the garage that stay colder than others. That's your heating escaping through gaps you can't see until you look closely.
The Real Cost of Waiting
Replacing weather stripping and seals is inexpensive. A bottom seal replacement typically runs $150 to $400 depending on your door size and material. Side and top seals might add another $100 to $250. These numbers assume you catch the problem early.
Wait too long, and water seeps through. We've seen water damage inside garages that cost thousands to remediate. We've also fielded calls from homeowners who discovered they had a rodent family living in their garage walls because the bottom seal had completely separated.

How We Replace Weather Stripping and Seals
The process isn't complex, but it demands precision. We start by removing the old seal carefully, scraping away old adhesive and debris so the surface is clean. A loose old seal hanging off the frame pulls new material away from the gap.
Next, we inspect the frame itself. If wood is rotted or metal is bent, we address that first. A new seal can't seal against a damaged frame. Then we measure twice and cut the new weather stripping or seal to length. Installation requires snug fitting to the frame without crimping or folding.
For bottom seals, we ensure the threshold sits flush against the floor so no light passes under. For side and top seals, we verify alignment so the door closes smoothly without binding.
The work takes 1 to 2 hours for most residential doors. You'll notice the difference immediately: less noise, no visible light, and a tighter feel when the door closes.
Why Nearby Areas Like Keizer Benefit From Regular Seal Checks
Homeowners in Keizer and across the greater Salem metro area experience the same weather patterns as Saint Paul. Wet winters and dry summers create expansion and contraction cycles that crack seals faster than many realize.
We recommend checking your seals twice yearly: once before winter and once after spring thaw. It's a five-minute inspection that can save you hundreds in heating costs and water damage repair.

Frequently Asked Questions
How do I know if my bottom seal is failing? Light visible under the closed door, water pooling inside after rain, cold air blowing in, or visible cracks and separation from the frame all indicate failure. A failing bottom seal typically needs replacement within days, not weeks.
Can I replace weather stripping myself? Removing old material is straightforward, but proper installation requires precision to ensure airtightness. Misaligned seals cause the door to bind or leave gaps. Professional installation guarantees the job is done right and lasts as long as intended.
How often should I replace seals? Most side and top weather stripping lasts 3 to 5 years. Bottom seals wear faster and typically need replacement every 2 to 3 years in high-use garages or harsh climates like ours here in Saint Paul.
Will new weather stripping stop rodents? A properly installed bottom seal closes the main entry point, but rodents can find other gaps. We recommend sealing any visible cracks in the frame or foundation as well to fully protect your garage.
What's the difference between rubber and vinyl seals? Rubber seals are durable and flexible in cold temperatures but can degrade faster in sunlight. Vinyl lasts longer and resists UV damage but can become brittle in extreme cold. We'll recommend the best material for your specific door and climate exposure.
