Few solutions are as effective in protecting your garage from the elements as adequately installed weather stripping. Many homeowners face the question of how to install garage door weather stripping when dealing with drafty garages, water leakage, or pest infiltration issues. Quality weather stripping creates a crucial seal that not only improves your garage’s energy efficiency but also extends the life of your door by preventing moisture damage and reducing strain on your opener system.
CCM Garage Doors specializes in helping homeowners tackle this critical maintenance task, whether you want to do it yourself or prefer professional installation. With the right approach and materials, you can transform your garage into a better-protected, more comfortable space, regardless of what Mother Nature throws your way.
What Is Garage Door Weather Stripping?
Garage door weather stripping serves as a protective barrier between your garage’s interior and the outside world. This versatile material creates seals around the perimeter of your garage door to block unwanted elements from entering.
Weatherstripping is designed to prevent various intrusions, including rain and moisture that can damage belongings and create mold issues, cold air that increases heating costs and creates uncomfortable working conditions, dust and debris that make keeping your garage clean nearly impossible, insects and tiny pests looking for shelter, and hot air during summer months that can make your garage unusable.
Different types of weather stripping are designed for specific areas of your garage door. Bottom seals attach to the door’s lower edge and compress against the floor when closed. Threshold seals adhere to the garage floor, creating a tight seal with the door’s bottom. Side seals mount to the vertical door jambs to eliminate gaps when the door is closed. Top seals attach to the horizontal header where the door meets the wall above.
Each type serves a specific purpose in creating a complete weather barrier around your entire garage door.
Tools and Materials Needed
Before beginning your installation, gather all necessary supplies to ensure a smooth process. Having everything prepared will save time and prevent interruptions.

Pro Tip: Many hardware stores sell weather stripping in bulk, but purchasing a weather stripping kit for garage doors will ensure you have the correct sizes and types for your specific door model.
Step-by-Step Installation Guide
Here is a step-by-step guide on how to install garage door weather stripping properly and effectively.
A. Bottom Seal Installation
The bottom seal (a door sweep) prevents water, pests, and debris while creating a smooth transition between your door and floor.
- Preparation. Begin by fully raising and securing your garage door. Examine the bottom retainer track to identify how the old seal is attached, then remove it by sliding it out or removing fasteners.
- Cleaning. Thoroughly cleans the retainer track, removing all dirt, old sealant, and debris. Allow the track to completely dry before proceeding to ensure proper adhesion.
- Installation For T-style seals, slide the T-shaped edge into the track along the door’s bottom. U-style seals require inserting the U-shaped portion around the door edge, while screw-on types need positioning before securing with the provided hardware.
- Finishing: Trim any excess material with a utility knife, leaving approximately 1/4 inch extending beyond each side. Lower the door slowly to test the seal’s contact with the floor and adjust if needed.
B. Threshold Seal Installation
The threshold seal adheres to your garage floor, creating a secondary barrier that works with your bottom seal for maximum protection.
- Proper positioning: Lower your garage door entirely and mark where it meets the floor using chalk or tape. Then, raise the door to provide adequate working space for installation.
- Surface Preparation Clean the floor area where the threshold will be installed, removing oil stains, dirt, and debris. Allow the surface to completely dry before proceeding with installation.
- Installation: If needed, apply adhesive to the threshold’s bottom surface, then position it precisely along your marked line. Press firmly to ensure complete contact with the floor, and secure with concrete screws is recommended.
- Curing: Allow the adhesive to cure according to the manufacturer’s instructions, typically 24-48 hours. Keep the garage door open during this entire period to prevent premature contact.
C. Side & Top Seal Installation
Side and top seals complete your weather barrier by addressing gaps around the perimeter of your garage door.
- Measuring and Cutting: Measure the height of your garage door sides and the width of the top, adding 1-2 inches to ensure complete coverage. Cut the weather stripping to these lengths with a utility knife or heavy-duty scissors.
- Preparation: Clean the door jambs and header where strips will be attached. Remove old weather stripping, nails, staples, or adhesive residue to ensure a clean mounting surface.
- Installation: Position the seals along the jambs and header where the door meets the frame, with the flexible portion facing the door. Attach with screws or nails every 8-12 inches, starting from the bottom and working upward.
- Adjustment: Close the door thoroughly to check for proper compression of the seals. Make any necessary adjustments to ensure optimal contact around the entire perimeter.
Common Mistakes to Avoid
Even experienced DIYers can make errors when installing weather stripping. Being aware of common pitfalls will help ensure a successful installation.
| Mistake | Explanation | How to Avoid |
| Incorrect Sizing | Using weather stripping that’s too narrow or thin won’t create an effective seal. | Measure carefully and purchase materials that adequately cover your specific door model. |
| Skipping Surface Preparation | Failing to clean mounting surfaces leads to poor adhesion and premature failure. | Before installation, thoroughly remove all dirt, old adhesives, and oils. |
| Improper Corner Joining | Poor connections at corners create vulnerability points in your weather barrier. | Ensure top and side seals overlap slightly, and consider mitering corners at 45-degree angles for a professional finish. |
| Ignoring Small Gaps | Even tiny openings can allow surprising amounts of air, water, or pests to enter. | Address all openings during your installation and final inspection, no matter how small. |
| Cold Weather Installation | Many adhesives and flexible materials become difficult to work with in low temperatures. | Plan your installation when temperatures are between 50-75°F for optimal material flexibility and adhesive performance. |
| Overtightening Hardware | Excessive tightening can compress and damage weather stripping. | Secure fasteners firmly but allow flexible portions to maintain their natural shape and compression abilities. |
| Misalignment | Improper alignment leads to ineffective sealing and premature wear. | Take extra time to ensure precise positioning, especially with threshold seals against the door’s closed position. |
Maintenance Tips for Weather Stripping
Proper maintenance extends the life of your weather stripping and ensures continued protection for your garage.
| Maintenance Task | Frequency | Why It’s Important |
| Inspect for cracks or gaps | Every 3–6 mos | Prevents energy loss and pest entry |
| Clean seals with mild soap | Quarterly | Keeps seals flexible and mold-free |
| Reapply adhesive if loose | As needed | Ensures lasting hold |
| Replace worn-out seals | Every 2–5 yrs | Maintain optimal insulation & sealing |
| Clear debris from the threshold | Monthly | Prevents damage and improves seal |
| Apply silicone lubricant | Annually | Preserves flexibility and prevents cracking |
Bonus Tip: Schedule seasonal inspections after extreme weather events to catch any damage early. Prevention is always easier than dealing with water damage or pest infestations.
FAQs
How often should I replace my garage door weather stripping?
You should typically replace your garage door weather stripping every 3 to 5 years or sooner if you notice signs of damage, such as cracking or tearing, or if it’s no longer creating a tight seal. Regular inspection will help you determine when replacement is necessary for optimal performance.
Can I install weather stripping myself, or should I hire a professional?
Installing garage door weather stripping can be a DIY project for those comfortable with basic tools and home repairs, as most types are relatively straightforward to install with adhesive or fasteners. However, hiring a professional can save time and guarantee a proper fit if you’re unsure about the process, have a large or complex door, or want to ensure a perfect seal.
What’s the cost of weather stripping installation?
The cost range for garage door weather-stripping materials typically ranges between $20 and $60, depending on the type (bottom, threshold, side/top), material quality, and door size. Premium kits with heavy-duty rubber or vinyl seals may cost slightly more but offer better durability and insulation.
Does weather stripping help with pest control?
Yes, garage door weather stripping can effectively aid pest control by sealing gaps that insects, rodents, and other small creatures might use to enter your garage. A tight seal along the bottom and sides helps create a physical barrier.
Are there weather-stripping options for uneven garage floors?
Yes, there are weather-stripping options specifically designed for uneven garage floors. Look for thicker rubber or flexible vinyl bottom seals that can compress and conform to irregularities in the floor surface, ensuring a better seal even on uneven concrete.
