What Exactly is a Garage Nail-On Bottom Seal? 

Nail-On Garage door bottom seals are similar to regular bottom seals, except that they are nailed onto the bottom of your garage door compared to being slid into a retainer. This design is slightly outdated, yet if you decide to get or replace a nail on seal, we will show you how.  

Preparing your installation site and ensuring you have the proper tools is key for an easy installation. 

Tools You Will Need 

• Measuring Tape 
• Wire Brush 
• Paper Towels/Wet Rag 
• Box Cutter 
• Hammer 
• Nails 
• Wood Sealer 
• Vise Grips 

How to Install Your Garage Nail-On Bottom Seal 

Follow these steps to install your seal easily and effectively: 

1. Raise the Garage Door 

Lift the garage door to a comfortable height for easy access. If your garage door is automatic, find a height that is suitable for you to remove the old bottom seal. If your door is not automatic, you can secure a pair of vise grips to the garage rail or place a large heavy object between the door and the ground (with assistance). 

2. Remove the Old Weather Seal

If there’s already an old weather strip, it’s time to take it off. Use a hammer or pry bar to carefully remove any nails or screws underneath the seal. If there are any stubborn nails left, hammer them flat to create a clean surface and then remove them. 

3. Clean the Bottom of the Door

Using a wire brush or something similar, scrub the bottom of your garage door to remove any debris or rough patches. You may want to wipe the bottom of the garage door with a damp rag or paper towel if there is any dirt or grime. Allow the wood to dry before moving on to the next step.

A smooth, clean surface will help the new seal stick properly. For added durability, consider sanding the bottom edge and sealing it with wood sealer. 

4. Measure and Trim the New Seal

Measure your garage door with the measuring tape to determine the exact length you’ll need. Cut the new weather seal to fit, trimming any extra length with the box cutter. 

5. Attach the Weather Seal

With the lip of the seal facing the inside of the garage, start nailing the seal onto the door. Use the provided nails (or your preferred fasteners) to secure it, spacing them evenly along the bottom to keep the seal secure. You should optimally aim to hammer each nail in the center of the weather seal. 

6. Test the Seal

Once it’s installed, double-check for any loose nails and clean away any leftover dust or debris. Then, close the garage door to check for any gaps. If you notice any, you may need to adjust your garage door motor to ensure a snug fit or trim any excess weather sealing. Should you decide to upgrade your garage to a more modern solution, consider retainer-based weather sealing options.
