Adhesive bonds threshold seals to the floor. Use weatherproof glue for strong holds. Follow product instructions carefully.

Replacement Screws or Nails
Screws or nails secure seals tightly. Choose rust-resistant ones for longevity. Match size to your door’s frame.

Cleaning Supplies (e.g., Soap, Water, Cloth)
Soap, water, and a cloth clean the door’s edges. Remove dirt for better seal adhesion. Dry thoroughly before installing.

Lubricant (Optional, for Smooth Installation)

Assessing the Garage Door

Checking for Existing Seal Condition
Look at current seals for damage. Check for cracks, tears, or loose fits. Replace worn seals to stop leaks.

Identifying Gaps or Damage
Examine door edges for openings. Spot rust, dents, or warped areas. Fix gaps to keep out weather and pests.

Measuring the Door Dimensions
Measure the door’s width and height. Use a tape measure for accuracy. Write down sizes to buy the right seal.

Matching Seal Type to Garage Door Material
Choose seals that fit your door. Rubber seals work for wood doors. Vinyl seals suit metal or aluminum doors.

Considering Climate and Weather Conditions
Select seals for your area’s weather. Use rubber for cold winters. Pick vinyl for hot, rainy climates.

Durability and Maintenance Requirements
Pick seals that last years. Check if they need frequent cleaning. Durable seals save time and money.

Wearing Gloves and Safety Glasses
Wear gloves to avoid cuts. Use safety glasses to protect eyes. Sharp tools or debris can cause injury.

Ensuring the Garage Door Is Secure
Lock the door in the open position. Use clamps to hold it steady. A moving door can be dangerous.

Disconnecting Automatic Opener (If Applicable)
Unplug the garage door opener. This prevents unexpected movement. Follow the manual to disconnect safely.

Cleaning the Garage Door

1. Removing Old Seals
   Pry off old seals with pliers. Check for stuck pieces in tracks. Clear all remnants to ensure a smooth surface.
2. Cleaning Debris and Dirt from Seal Area
   Wipe door edges with soap and water. Scrub dirt or grime with a cloth. Clean tracks for better seal adhesion.
3. Drying the Surface
   Dry the door with a clean towel. Ensure no moisture remains. A dry surface helps seals stick properly.

Measuring and Cutting the Seal

Start by measuring the garage door’s bottom, sides, and top with a measuring tape. Write down each length carefully and double-check for accuracy to avoid mistakes. Next, mark the seal with a pencil where it needs to be cut. Use a utility knife to make straight, clean cuts for a snug fit. Test the seal’s length against the door before finalizing. Trim any excess if needed and ensure no gaps remain for a tight, effective seal.

Installing Bottom Seals

Slide the bottom seal into the track under the garage door or snap it firmly into place. Check that it moves smoothly without resistance. If the seal requires adhesive, apply it evenly, or use screws for a stronger hold, tightening them with a screwdriver. Open and close the door slowly to test the fit. Look for dragging or gaps and adjust the seal if it sticks to ensure proper function.

Installing Threshold Seals

Place the threshold seal on the garage floor, aligning it with the door’s edge, and mark its position with chalk for accuracy. Spread adhesive under the seal and press it firmly to the floor, or use screws for extra strength if needed. Close the door to check alignment, ensuring the seal touches evenly with no gaps. Adjust the seal’s position if necessary to create a tight barrier against weather and pests.

Attach the weather stripping to the sides and top of the door frame, making sure it covers any gaps. Use nails, screws, or glue to hold it in place, depending on the instructions. Close the door to check for any gaps or air leaks. If needed, adjust the seal so it fits tightly and keeps out weather.

Open and close the door a few times to make sure it moves smoothly. Cut off any extra seal material for a neat finish. If the door sticks, use a little silicone spray on the moving parts. Adjust the seal if there are any gaps or if it drags, so everything works just right.

Fix gaps or leaks after installation by repositioning the seal or adding extra adhesive. If the seal won’t stay in place, use stronger screws or clean the surface again. For difficulty closing the door, check for overly tight seals and trim slightly. Tighten loose seals with nails or replace uneven ones for a proper fit.
