Why Garage Door Weather Stripping Matters
If your garage feels drafty or you notice water or bugs sneaking in, worn-out weather stripping is likely to blame. Here’s why installing new stripping is important:
- Energy efficiency: Keeps warm air inside during winter and cool air during summer.
- Pest control: Blocks out rodents, insects, and snakes.
- Moisture prevention: Protects tools, walls, and storage from water damage.
- Noise reduction: Helps insulate from outdoor sounds.
- Improved security: Seals prevent prying eyes and objects from slipping inside.
Types of Garage Door Weather Stripping
Not all weather stripping is the same. Choose the right type for your garage door:
| Type | Best For | Notes |
| Bottom Seal | Cracks under the door | Comes in a U-shape, J-type, or bulb-shape |
| Threshold Seal | Severe water protection | Installed directly on the floor |
| Stop Molding | Gaps around the sides/top of the door frame | Great for wooden doors |
| Brush Seal | Commercial/rolling doors | Durable; great for heavy-duty use |
Pick based on your climate and how much protection you need.
Tools & Materials Needed
Before you start, make sure to gather the following items to ensure a smooth installation:
- New weather stripping (ensure it’s the correct type and length for your garage door)
- Utility knife or scissors (for cutting the weather stripping to size)
- Hammer and nails OR drill and screws (to secure the weather stripping in place)
- Screwdriver (for tightening screws)
- Measuring tape (to measure the correct length of the weather stripping)
- Pencil (for marking measurements on the weather stripping)
- Adhesive (if using a threshold seal for added sealing)
- Clean rag and mild cleaner (for cleaning the garage door frame before installation)
Pro Tip: Always double-check your measurements before cutting the weather stripping. Taking the time to measure twice will ensure a precise fit and avoid wasting materials.
Step-by-Step: How to Install Garage Door Weather Stripping
Step 1: Remove Old Weather Stripping
Gently pry off the old weather stripping using a flathead screwdriver. Carefully remove any nails or screws holding it in place. Discard the old materials and inspect the frame for mold, rust, or pest damage. Address any issues before proceeding with the new installation.
Step 2: Clean the Surface Thoroughly
Before installing new weather stripping, clean the door frame with a mild cleaner or rubbing alcohol. Remove any dirt, oil, or adhesive residue from the surface. A clean frame ensures better adhesion and a more durable seal. Take your time to ensure the surface is fully prepared.
Step 3: Measure and Cut New Stripping
Measure the width and height of your garage door carefully with a tape measure. Add a little extra to the length to allow for trimming. Lay the new weather stripping flat and use a utility knife to cut it to the exact size needed for a perfect fit.
Step 4: Install the Bottom Seal
For track-style bottom seals, simply slide it into the retainer. For nail-on or adhesive-backed seals, align and secure the strip along the bottom edge of the door frame. Start from one end and work your way across, ensuring not to stretch the material too tightly for proper sealing.
Step 5: Install Top and Side Weather Stripping
Use stop molding to secure the weather stripping along the top and sides of the garage door frame. Align the edge of the stripping with the point where the door contacts the frame. Secure it by nailing or screwing every 12–16 inches for a firm, lasting fit.
Step 6: Optional – Install Threshold Seal
If you experience significant water intrusion, consider installing a threshold seal on the garage floor. Clean the floor surface thoroughly, apply adhesive, and press the seal firmly in place. Let it cure according to the manufacturer’s instructions to ensure a watertight seal for your garage door.
Common Mistakes to Avoid
Here are some common mistakes to avoid when installing garage door weather stripping:
- Stretching the seal too tight: Pulling the seal too tightly can cause it to crack and wear out prematurely, leading to ineffective sealing and unnecessary replacements.
- Using indoor-grade material: Always use weather-resistant materials designed for outdoor use. Indoor-grade materials won’t withstand the harsh weather conditions, reducing the effectiveness of your seal.
- Not testing door movement: After installation, it’s crucial to test the door’s movement. If the seal is misaligned, it can cause the door to jam or not close properly, resulting in potential damage.
- Skipping surface cleaning: Proper surface cleaning before applying adhesive-backed seals is essential. Dirt, grease, and debris can prevent the adhesive from bonding effectively, shortening the lifespan of the seal and compromising its performance.
Avoiding these common mistakes will help ensure that your garage door weather stripping performs well for an extended period.
When to Replace vs. When to Repair
Wondering if your seal just needs a fix? Use this checklist:
| Condition | Repair or Replace? |
| Small gap or crack | Garage Door Repair (patch or seal) |
| Torn or missing sections | Replace |
| Flattened over time | Replace |
| Bugs/water still entering | Upgrade seal type |
Pro Tip: In extreme climates, inspect your seals seasonally.
Maintenance Tips for Long-Lasting Performance
Weatherstripping typically lasts 2-5 years, but regular maintenance can help extend its lifespan. Follow these tips to keep your garage door weather stripping in top condition:
- Inspect seals every 3 months: Regularly check for signs of wear or damage, such as cracks or gaps, and address them promptly.
- Clean with mild soap: After storms or heavy rains, gently clean the weather stripping with mild soap and water to remove dirt and debris, ensuring the seal remains effective.
- Reapply adhesive if necessary: If you notice that the corners of the weather stripping are starting to peel or lose their adhesion, reapply the adhesive to maintain a tight seal.
- Lubricate nearby moving parts: Apply lubricant to the hinges and other moving parts of the garage door to reduce friction and prevent undue stress on the weather stripping.
By following these simple steps, you can maximize the performance and lifespan of your garage door weather stripping.
