Weatherstripping creates a tight seal around your garage door, blocking gaps where air, rain, or insects can enter. Regular inspection and replacement are key to keeping it effective, especially in our humid Naples climate.

Here are the most common types of weatherstripping to consider:

• Vinyl or rubber seals: Flexible and durable, these are ideal for sealing the sides and top of the garage door.
• Brush weatherstripping: Made of dense bristles that contour to the surface of the door, these are great for irregular or uneven gaps.
• Garage door bottom seals: These attach to the lower edge of the door to block drafts, dust, and small pests.
• Threshold seals: Installed on the floor beneath the door, these add an extra layer of protection by sealing the gap between the door and the concrete.



By combining these sealing methods, you’ll create an airtight barrier that improves comfort and helps reduce energy loss.

Installing a Garage Door Threshold Seal

A threshold seal works hand in hand with your weatherstripping. It’s installed directly on the floor where your garage door closes, compressing tightly to block air and moisture.

Here’s how to install one effectively:

1. Measure and cut – Measure your garage door width and cut the seal to fit.
2. Clean the surface – Remove dust, debris, or old adhesive so the new seal bonds properly.
3. Apply adhesive – Use a high-quality adhesive recommended by the manufacturer.
4. Position and press – Lay the seal along the floor, ensuring a snug fit.
5. Test and adjust – Close the door and make sure it compresses evenly for a complete seal.



Routine cleaning and checking for wear can extend your threshold seal’s lifespan, keeping your garage better protected all year round.

Keep the Elements Out for Good

Weatherstripping and threshold seals may seem like small details, but they make a big difference. Together, they help block moisture, reduce drafts, and maintain a more comfortable and energy-efficient garage.
