A garage door threshold, also known as a garage door seal, is a weather-resistant barrier placed along the bottom of the garage door opening.

Its primary purpose is to create a tight seal between the garage floor and the bottom of the door, preventing various elements from entering the garage space. Here’s a comprehensive overview of what a garage door threshold is and why it’s important:

Function and Benefits

• Weather Protection: One of the main functions of a garage door threshold is to prevent rainwater, snow, leaves, dust, and other outdoor debris from entering your garage. This is particularly important for keeping your garage interior clean and dry.
• Pest Prevention: A well-installed garage door threshold can also deter pests like rodents, insects, and small animals from entering your garage. This helps maintain a cleaner and more sanitary environment.
• Energy Efficiency: The garage is often connected to the main house, and an effective threshold can help improve energy efficiency by reducing drafts and heat loss through gaps at the bottom of the garage door.
• Noise Reduction: A properly sealed garage door can help reduce the amount of noise from outside that enters your garage, creating a quieter environment.
• Protection of Stored Items: Many homeowners use their garage not just for parking vehicles, but also for storage. A garage door threshold can help protect the items stored in your garage from moisture and dirt.

Types of Garage Door Thresholds

• Rubber Thresholds: These are flexible and often made from heavy-duty rubber or a combination of rubber and vinyl. They are easy to install and conform to the shape of the garage floor.
• Aluminum Thresholds: These are durable and long-lasting options that often come with a rubber or vinyl seal. They can be more rigid than rubber thresholds and may require a more precise installation.
• Vinyl Thresholds: These are lightweight and easy to install. They are suitable for residential use and can provide adequate weather protection.
• DIY Kits: Many garage door threshold kits are available in the market, which include all the necessary components for installation, such as the threshold itself, adhesive, and instructions.

Installation: Installing a garage door threshold is a relatively simple process that typically involves the following steps:

• Clean the Area: Ensure the garage floor is clean and free from debris before installation.
• Cut to Size: Measure the width of your garage door opening and cut the threshold to the appropriate length if needed.
• Apply Adhesive: Apply the adhesive to the back of the threshold and press it firmly against the garage floor, aligning it with the bottom of the garage door.
• Secure in Place: Depending on the type of threshold, you might need to secure it further using screws or nails.
• Allow Adhesive to Cure: Follow the manufacturer’s instructions for the recommended curing time of the adhesive before using the garage door.
