A worn or damaged seal can lead to drafts, water leaks, and even increased energy bills.

When to Replace Garage Door Bottom Seal

Knowing when to replace your new garage door bottom seal is essential. Here are the key indicators that it’s time for a replacement:

• Visible Wear and Tear:
  
  • Cracks: Inspect the seal for any cracks that could let in air, water, or pests.
    
    
  • Gaps: Check for gaps where the seal no longer makes full contact with the garage floor.
    
    
  • Hardening: If the seal has become stiff or brittle, it’s less effective at creating a tight seal.
    
    
• Environmental Indicators:
  
  • Drafts: Feel for drafts around the bottom of the garage door, especially on windy days.
    
    
  • Water Leaks: Look for signs of water intrusion, such as damp spots or puddles inside the garage.
    
    
  • Pest Ingress: Notice any signs of pests like insects or rodents getting into the garage.
    
    
• Functional and Cost Indicators:
  
  • Increased Energy Bills: A faulty seal can lead to higher heating or cooling costs due to loss of temperature control.
    
    
  • Difficulty in Door Operation: If the garage door is harder to open or close, the seal might be interfering with its movement.

It’s always a big time-saver to prepare everything you might need to repair anything. Before proceeding with the following steps, gather the tools and materials specifically listed below:

Three Methods to Replace Garage Door Bottom Seal

There are several methods to repair or replace your garage door bottom seal, depending on the type of door and seal you have. This guide will cover three common ways: weather-sealing your garage door, replacing rotting garage door trim, and cleaning up a rusty door track. Each method includes detailed step-by-step instructions.

A. Weather-Seal Your Garage Door

Weather-sealing your garage door involves replacing the bottom seal to ensure a tight fit, which helps keep out the elements, pests, and debris. Here’s how to do it:

Step-by-Step Instructions:

1. Measure the Width of Your Garage Door:
   
   • Use a tape measure to determine the exact width of your garage door. This measurement will guide you in purchasing the correct length of the new seal.
     
     
2. Purchase the Appropriate Type and Length of Weather Seal:
   
   • Choose the correct type of seal for your door, such as T-style, U-style, or bulb-style. Make sure the length matches the width of your door.
     
     
3. Remove the Old Seal:
   
   • If the seal is attached with screws, use a screwdriver to remove them. If it is slotted into a track, pull it out gently. For glued seals, a utility knife might be needed to cut through the adhesive.
     
     
4. Clean the Track Thoroughly:
   
   • Use an all-purpose cleaner and a scrub brush to remove any debris, dirt, or old adhesive from the track. Wipe it down with a rag or paper towel to ensure it’s completely clean and dry.
     
     
5. Insert the New Seal into the Track:
   
   • Align the new seal with the track and gently push or slide it into place. For a tight fit, you might need to use pliers to help guide the seal into the track.
     
     
6. Secure the Seal According to the Manufacturer’s Instructions:
   
   • Follow the specific instructions provided with the new seal to secure it properly. This may involve screwing it in place or applying adhesive.
     

B. Replace the Rotting Garage Door Trim

Replacing rotting garage door trim not only improves the appearance of your door but also prevents further damage from moisture and pests.

Step-by-Step Instructions:

1. Inspect the Trim Around Your Garage Door for Signs of Rot or Damage:
   
   • Look for areas where the trim is discolored, soft, or visibly decayed.
     
     
2. Use a Pry Bar to Carefully Remove the Damaged Trim:
   
   • Insert the pry bar under the trim and gently lift it away from the door frame. Be cautious to avoid any damage to the frame.
     
     
3. Measure and Cut New Trim Pieces to Fit:
   
   • Use the old trim as a template or measure the door frame directly. Cut the new trim pieces to the correct length and width.
     
     
4. Apply a Coat of Primer and Paint to Protect the New Trim:
   
   • Before installing the new trim, apply a coat of primer and then paint it. This will help protect the wood from moisture and extend its lifespan.
     
     
5. Attach the New Trim Using Nails or Screws, Ensuring a Tight Fit:
   
   • Secure the new trim in place with nails or screws, making sure it fits snugly against the door frame.
     
     

C. Clean Up a Rusty Door Track

Cleaning up a rusty door track can improve the smooth operation of your garage door and extend the life of the track.

Step-by-Step Instructions:

1. Inspect the Garage Door Track for Rust or Debris:
   
   • Look along the entire length of the track for rust spots or accumulated debris.
     
     
2. Use a Wire Brush or Sandpaper to Remove Rust and Clean the Track:
   
   • Scrub the rusty areas with a wire brush or sandpaper until the rust is removed and the metal is smooth.
     
     
3. Wipe Down the Track with a Damp Cloth to Remove Any Remaining Particles:
   
   • Use a damp cloth to wipe away any dust or particles left behind after scrubbing.
     
     
4. Apply a Rust-Inhibiting Primer to Prevent Future Rust:
   
   • Once the track is clean and dry, apply a rust-inhibiting primer to the exposed metal to protect it from future rusting.
     
     
5. Lubricate the Track with a Suitable Garage Door Lubricant:
   
   • After the primer has dried, apply a silicone-based lubricant to the track to ensure smooth operation of the garage door.

What should I do if the new seal doesn’t fit?

If the new seal doesn’t fit, first double-check that you have purchased the correct type and size for your specific garage door model. If the size is incorrect, you may need to trim the seal to fit or exchange it for the right size. If the type of seal is incorrect, consult your garage door manufacturer’s specifications or seek advice from a professional. Proper fitting is crucial for the seal to work effectively, so take the time to ensure it fits snugly and securely.
