How To Replace A Garage Door Weatherstrip

Springs Pulleys Chains Power

Let’s be real—garage doors aren’t exactly the rockstars of home maintenance. But when that chilly Edmonton wind starts whistling through the gap under your door like it’s auditioning for a horror movie soundtrack, suddenly that humble weatherstrip becomes very important. Lucky for you, replacing it isn’t rocket science. We’ve tackled more weatherstrips than we can count (thanks, Alberta winters), and today, we’re sharing our pro tips so you can DIY this without turning it into a weekend saga.

Why Bother? The Magic of a Good Weatherstrip

Think of your weatherstrip as the bouncer of your garage. It keeps out drafts, pests, and that suspicious puddle of melted snow trying to sneak in every spring. But over time, it cracks, shrinks, or just gives up the ghost—especially after a few Sherwood Park winters. If your garage feels like a wind tunnel or you’ve spotted daylight under the door, it’s time for a replacement.

FYI: Ignoring this can lead to bigger headaches (and higher heating bills). And hey, if you’re not into DIY, our team at Overhead Door Pros is just a call away. We handle everything from garage door repair to automatic garage door opener installation—no judgment here.


Tools You’ll Need (No, You Don’t Need a PhD)

Grab these basics:

  • New weatherstrip (vinyl or rubber—we’ll debate this later)
  • Utility knife
  • Pliers
  • Screwdriver
  • Measuring tape
  • Soapy water (trust us)

Pro tip: Buy a weatherstrip that’s slightly longer than your door’s width. Better to trim excess than come up short and make a second trip to the hardware store.


Step 1: Remove the Old Weatherstrip—RIP, Buddy

First, lift the garage door halfway to relieve tension on the weatherstrip. Locate the metal retainer strip holding the old weatherstrip in place—it’s usually nailed or screwed along the bottom of the door.

  • If it’s nailed: Use pliers to yank those nails out. Channel your inner Hulk if needed.
  • If it’s screwed: Unscrew the retainer strip. Save the screws unless they’re rusted (Edmonton winters, amirite?).

Pull out the old weatherstrip. If it’s stubborn, a utility knife can slice through any adhesive.

Warning: If your door has broken springs or garage door cable repair needs, STOP. Those are jobs for pros like us. Seriously, springs are dangerous—don’t risk it.


Step 2: Measure Twice, Cut Once (Grandpa Was Right)

Measure the width of your garage door. Unroll the new weatherstrip and cut it to length with your utility knife. Leave an extra inch on each end for a snug fit.

Pro Debate: Vinyl vs. Rubber Weatherstrips

  • Vinyl: Affordable, stiff, and durable. Great for standard doors.
  • Rubber: Flexible and better for uneven surfaces. Costs a bit more.

IMO, rubber’s worth the splurge if your door isn’t perfectly aligned. Speaking of alignment, if your door is crooked, check out our guide on garage door track alignment—or let us handle it.


Step 3: Install the New Weatherstrip—Easy Peasy

  1. Soak it: Dip the weatherstrip in soapy water. This makes it slippery and easier to maneuver.
  2. Slide it: Insert the top edge of the weatherstrip into the retainer strip’s groove. Start at one end and work your way across.
  3. Secure it: Reattach the retainer strip with screws or nails. If using nails, space them 6-8 inches apart.

Bold Pro Tip: Ensure the weatherstrip touches the ground when the door is closed. Too high? Adjust the retainer strip or trim the weatherstrip.


Step 4: Test It Out (Cue the Confetti)

Close the door and check for gaps. If air’s still getting through, your door might need garage door spring adjustment or torsion spring replacement to sit properly.

Funny Story: One customer replaced their weatherstrip three times before realizing their door was misaligned. Don’t be that person. If things get weird, call us.


When to Call the Pros (We Won’t Tell)

Replacing a weatherstrip is DIY-friendly, but let’s face it—some jobs aren’t. If you spot any of these, hit pause:

  • Noisy garage door that sounds like a zombie moaning
  • Broken spring (unless you’re training for the Olympics)
  • Commercial garage door repair needs (bigger doors = bigger risks)

Overhead Door Pros handles automatic garage door installation, garage door opener repair, and even garage door replacement across Edmonton and Sherwood Park. Why stress when we can fix it in a snap?


Weatherstrip Cost Breakdown: What’s the Damage?

Item Price Range
Vinyl Weatherstrip $15–$30
Rubber Weatherstrip $25–$50
Professional Installation $100–$200

FYI: If your door needs other TLC—like garage door track repair—bundling services can save cash.


FAQs: Your Weatherstrip Questions, Answered

  1. How often should I replace my weatherstrip?
    Every 2–3 years, or sooner if you spot cracks. Edmonton’s moody weather accelerates wear.
  2. Can I reuse the old retainer strip?
    Only if it’s not rusted or bent. When in doubt, replace it—they’re cheap.
  3. Why is my new weatherstrip leaking air?
    Your door might be misaligned. Check our garage door track alignment tips or call us.
  4. Is professional installation worth the cost?
    IMO, yes—if you’re short on time or patience. We’ll even spot other issues (like a noisy garage door) while we’re there.
