How To Seal A Garage Door

How to Seal a Garage Door: A No-Sweat Guide for the Practical Homeowner

Let’s face it: a drafty garage door is like that one friend who never quite closes the door behind them—annoying, wasteful, and cold. If your garage feels more like a wind tunnel or a sauna depending on the season, you’re not alone. We’ve all been there, shivering next to a gaping garage door while muttering, “Why didn’t I fix this sooner?” Well, grab a coffee (or a beer, no judgment here), and let’s tackle this together. At Silver Garage Doors in Mississauga, we’ve sealed more garage doors than we can count, and today, we’re sharing our pro tips to help you save energy, money, and sanity.

Why Bother Sealing Your Garage Door?

Before we dive into the how, let’s chat about the why. A poorly sealed garage door isn’t just a nuisance—it’s a money pit. Gaps and cracks let in:

• Drafts (hello, winter chill!),
• Pests (spiders love garages, apparently),
• Moisture (mold’s favorite party spot),
• Noise (because who doesn’t want to hear every garbage truck at 6 a.m.?).

And if you’re using your garage as a workshop, gym, or actual parking space, proper sealing keeps the space usable year-round. Plus, sealing your door can lower energy bills and extend the life of your garage door system. Win-win!

Tools & Materials You’ll Need

You don’t need a PhD in home improvement for this. Here’s the lowdown:

• Weatherstripping: The MVP of sealing. Choose vinyl or rubber—both are durable.
• Bottom seal kit: A.k.a. the “threshold seal.” This replaces the worn-out strip at the bottom of your door.
• Silicone caulk: For sealing stationary gaps around the door frame.
• A utility knife, screwdriver, and tape measure: Basic toolbox staples.
• Patience: Optional, but highly recommended.

FYI: If your garage door is older than your teenager’s TikTok account, consider a full garage door replacement. We’ve seen doors in Mississauga neighborhoods that were practically held together by hope and duct tape.

Step-by-Step: Sealing Like a Pro

1. Inspect Your Garage Door

Start by playing detective. Close the door and look for daylight peeking through gaps. Common trouble spots:

• The bottom of the door (where that sad, flattened seal lives),
• The sides and top of the door frame,
• Around windows (if your door has them).

Pro Tip: If your door sounds like a screeching owl when it moves (noisy garage door, anyone?), you might need garage door track repair or garage door spring repair. Those issues go beyond sealing—but we’ll get to that later.

2. Replace the Bottom Seal

This is where the magic happens.

• Step 1: Remove the old seal by pulling it out of the track or unscrewing it.
• Step 2: Measure the width of your door and cut the new seal to size.
• Step 3: Slide or screw the new seal into place.

Warning: If the bottom of your door is bent or damaged, even a new seal won’t help. You might need garage door cable repair or garage door capping to fix structural issues.

3. Install Side and Top Weatherstripping

• Vinyl weatherstripping sticks to the door frame and compresses when the door closes. Peel-and-stick for the win!
• For extra stubborn gaps, use silicone caulk along stationary parts of the frame.

Got a commercial space? Same rules apply, but scale up! Commercial garage door repair often involves heavier-duty materials—something we handle daily at Silver Garage Doors.

4. Check the Automatic Garage Door Opener

Wait, what does this have to do with sealing? If your door doesn’t close evenly, gaps will persist. Test your automatic garage door opener by closing the door and checking for alignment. If it’s crooked or jerky, you might need garage door opener repair or automatic garage door opener installation.

When to Call the Pros (Like Us!)

Look, we love a good DIY project. But some jobs scream “call Silver Garage Doors.” For example:

• Broken springs: These are under insane tension. One wrong move and… well, let’s just say it’s not pretty.
• Track misalignment: If your door looks drunk when it closes, the tracks need professional TLC.
• Automatic garage door installation: Wiring and motor setups? Leave it to the experts.

Not in Mississauga? No worries—we also serve Oakville and the GTA. Just Google “garage door service near me,” and we’ll pop up faster than a garage door sensor.

Maintenance: Keep That Seal Tight

Sealing isn’t a “one-and-done” deal. Twice a year, give your garage door some love:

• Clean debris from the bottom seal.
• Re-caulk cracks in the frame.
• Lubricate hinges and rollers to prevent noisy garage door symphonies.

Bonus: If your door starts sagging or struggling, it might be time for garage door spring repair or a garage door replacement.

Cost Breakdown: What to Expect

Worried about the price? Here’s a quick table to ease your mind:

IMO, investing in quality sealing now beats paying for energy leaks later. And hey, if you’re in Mississauga, give us a shout—we’ll make sure you get the best cost-to-quality ratio.

FAQs: Your Burning Questions, Answered

1. “Can I seal my garage door myself?”
Absolutely! Weatherstripping and caulk are DIY-friendly. But if you spot broken springs or cables, stop. Those require pro help.

2. “Why is my garage door so loud?”
Usually, it’s worn rollers, loose hardware, or lack of lubrication. We offer garage door service to silence the racket.

3. “How often should I replace the weatherstripping?”
Every 5–10 years, depending on wear. If it’s cracking or peeling, it’s time.

4. “Should I repair or replace my garage door?”
If repairs cost more than 50% of a new door, go for garage door replacement. Newer models are quieter and more efficient.
