Experts at Brother’s Garage Door Service have seen countless garages suffer from poor sealing. The consequences range from warped belongings due to humidity to significant increases in heating and cooling costs. Weather stripping creates an effective barrier against temperature extremes, moisture, dust, and unwanted critters, making it one of the most cost-effective improvements for any garage owner.
What Is Weather Stripping and Why Is It Important?
Weatherstripping refers to the material strips that seal the gaps between your garage door and its frame. These specialized materials create a barrier that blocks air, water, dust, and even tiny pests from entering through the inevitable gaps around your garage door. The importance of this simple upgrade becomes apparent during extreme weather conditions when properly sealed garages maintain more consistent temperatures, protecting both the garage structure and its contents.
Beyond temperature control, weather stripping offers several additional benefits: it reduces noise transmission, prevents water infiltration that could damage the door or garage floor, keeps out leaves and debris, and helps maintain garage cleanliness. Effective weather stripping is especially crucial for homeowners living in areas with seasonal weather changes as it adapts to different environmental conditions throughout the year.
Where Is Weather Stripping Installed on a Garage Door?
Weatherstripping is strategically placed around the entire perimeter of the garage door to create a complete seal. The primary locations include:
- Bottom Seal: Attached to the bottom edge of the door, this seal contacts the garage floor, preventing water, debris, and tiny pests from entering underneath.
- Side Seals: These vertical strips run along both sides of the door, sealing the gap between the door edges and the door jamb.
- Top Seal: Positioned along the top edge of the door, this seal prevents air leakage where the door meets the header.
- Panel Seals: These seals fit between the individual panels to prevent air infiltration through the hinged sections for sectional doors.
- Threshold Seal: This optional floor-mounted strip creates an additional ground-level barrier for maximum protection against water and drafts.
Types of Garage Door Weather Stripping
The effectiveness of your weather stripping largely depends on selecting the right type for each location around your garage door. Each material and design serves specific purposes and offers unique advantages.
| Weather Stripping Type | Best Uses | Material | Durability | Price Range |
| Bottom Seals (T-Style) | Floor contact, water barrier | EPDM rubber | 3-5 years | $$ |
| Bottom Seals (U-Style) | Uneven floors, maximum compression | Vinyl | 2-4 years | $$ |
| Threshold Seals | Water barrier, floor-mounted | PVC or rubber | 5-7 years | $$$ |
| Brush Seals | Sides, top, minimal friction | Nylon bristles | 5-8 years | $$ |
| V-Strip Seals | Sides, top, temperature control | Vinyl or rubber | 3-5 years | $ |
| Compression Weatherstrips | Sides, top, complete seal | EPDM foam | 4-6 years | $$ |
| Panel Seals | Between sections | Rubber | 3-5 years | $ |
When selecting weather stripping materials, consider your local climate conditions. Cold-weather areas benefit from flexible rubber that won’t crack in low temperatures, while hot, sunny regions require UV-resistant materials that won’t degrade quickly from sun exposure. The correct material choice ensures longer-lasting performance and better protection for your garage.

How to Install Garage Door Weather Stripping Efficiently
Step-by-Step Instructions
A systematic approach ensures proper installation and optimal garage door weather stripping performance. These straightforward steps will guide you through the entire process.
Step 1: Remove Old Seals
Begin by removing any existing damaged weather stripping using appropriate tools based on how it’s attached (nails, screws, or adhesive). Clean all surfaces thoroughly with mild detergent and allow them to dry completely before installing.
Step 2: Measure and Cut New Stripping
Measure each location where weather stripping will be installed: the bottom width of your garage door, the height of both side jambs, and the width of the top header. Using a utility knife or scissors, cut the weather stripping to size with a small allowance to ensure complete coverage.
Step 3: Install Bottom Seal
Identify your garage door’s bottom seal type (T-shape, U-shape, or O-shape) and slide the new seal into place, working from one side to the other to prevent stretching. Once fully installed, trim any excess material flush with the door edges for a clean finish.
Step 4: Attach Side and Top Seals
Position the weather stripping against the jambs and header where the door makes contact when closed, ensuring it will compress slightly without creating excessive resistance. Secure with appropriate fasteners (nails, screws, or adhesive) and test the door operation to verify proper clearance and seal compression.
Step 5: Apply Threshold Seal
Install a threshold seal directly beneath the closed garage door after thoroughly cleaning the floor surface for maximum protection. Secure according to the manufacturer’s instructions, apply silicone caulk at the junction with the floor, and allow adhesives to cure entirely before testing door operation.
Post-Installation Checks
After completing the installation, perform these essential checks to verify proper function and identify any adjustments needed:
- Inspect for light leaks or gaps.
- Test the door’s opening and closing function.
- Ensure the seals compress correctly without damage.
- Confirm there’s no interference with the garage floor.
- Verify that automatic safety reversing features.
- Check that water test by spraying water.
Maintenance Tips
Regular maintenance extends the life of your weather stripping and ensures continued protection for your garage.
- Clean the seals seasonally.
- Inspect the seals bi-annually.
- Apply a silicone-based lubricant.
- Replace any torn or brittle weather stripping.
- Keep the tracks and door threshold clear of debris.
- Adjust the garage door springs or opener sensitivity.
Common Challenges and Solutions
Even careful installation sometimes encounters challenges. Here are solutions to the most common issues:
| Challenge | Cause | Solution |
| Seal Doesn’t Compress Properly | Wrong seal type or poor alignment | Reinstall with the correct orientation or replace with the appropriate type |
| Adhesive Not Sticking | Dirty or wet surface | Clean thoroughly with alcohol, and ensure the surface is arid before reapplying |
| Bottom Seal Too Short | Incorrect measurements | Re-measure and replace with an appropriately sized seal; avoid stretching during installation |
| Door Dragging After Install | Seal too thick or misaligned | Choose a low-profile seal appropriate for your clearance or adjust the door track height slightly |
| Gaps Remain After Installation | Uneven surfaces or worn door edges | Use foam tape behind weather stripping to fill irregular spaces or consider door repair |
| Weather Stripping Cracking | Incorrect material for climate | Replace with climate-appropriate material (cold-flexible or UV-resistant as needed) |
| Side Seals Pull Away | Insufficient fasteners | Increase the number of fasteners or switch to screw-mounted types for better holding power |
| Pest Infiltration Despite New Seals | Overlooked entry points | Add corner seals where weather stripping sections meet or use pest-specific blockers |
