Different Seals for Garage Doors

There are a few different types of seals that can be used on garage doors. They are made of different materials and serve different functions. It is helpful to know what type of seal you have and what it does. In this blog post, we will discuss the different types of seals and what they do!

Top and Side Seals and Retainers

There are different types of weatherstripping seals used to seal your garage door sides and top.

PVC Stop Molding

Looking for a way to keep the elements out of your garage? Look no further than the top and side garage door weatherstripping seals! Made of durable PVC, stop molding seals effectively block out moisture, dirt, and pests while creating a tight seal around the sides and top of your garage door. Installation is easy – nail the stop molding to the outside frame of your garage door and let the flap press against the door to create a lasting seal.

Rigid Vinyl Reverse Angle Jamb Seal

The Rigid Vinyl Reverse Angle Jamb Seal is a great way to seal your garage door and keep the elements out. This seal secures a piece of angle iron outside the garage door and the flap on the seal points back to the door. When the door is closed, the flap on the Rigid Vinyl Reverse Angle Jamb Seal presses against the garage door to create a tight seal. This weatherstripping comes in four colors: brown, grey, white, and black.

Flap Seal

Flap seal garage door weatherstripping is specifically designed for Step Rabbit and Tongue & Groove garage door sections. We also offer a universal weatherstripping seal that will fit most other doors. Top flaps are made from durable material and come in black. Whether you’re looking to keep out the cold in winter or your garage cool in summer, flap-seal garage door weatherstripping is the perfect solution.

Brush Inserts

Used with top and side retainers, brush seals are made to fit in both standard and large slots. Standard-sized brush seals come at 1/2″, 3/4″, 1″, 1-1/2″, 1-3/4″, 2″, and 3″. These are all black seals, though the 1″, 2″ and 3″ brush seals can also be zebra seals. The zebra brush seals alternate between yellow and black. Large brush seals are sold in inch-wide increments from 1″ through 6″. No matter the size of your door, we have a seal that will fit perfectly!

If you’re looking for an easy and effective way to keep your garage door well-sealed and free from drafts, dirt, and leaves, then threshold seals are a great option. You can choose a peel-and-stick option or use an adhesive under the threshold.

In addition to protecting your garage from the elements, threshold seals also deter rodents, snakes, and pests from entering, creating a better seal overall that can help save on energy costs.


Garage Door Bottom Seals

Bottom seals are integral to weatherproofing your garage. There are three bottom seals: the bottom astragal, the twin-contact bottom seal, and the retainer with a bottom seal. The bottom astragal and the twin-contact bottom seal can be made from rigid plastic or foam, or hard rubber. While the retainer bottom seal typically has an aluminum or plastic l-shape with a seal on the bottom.

Bottom Astragal

Bottom astragals are available in solid and foam synthetic rubber options. Unlike twin-contact options, a bottom astragal makes a single point of contact with the floor. These single pieces of weatherstripping can be smooth or have ridges, referred to as a beaded threshold.

Twin-Contact Bottom Seal

These bottom seals have a straight flap with a flexible bulb seal. When the doors close, the edges seal the bottom of the door.

Retainer & Seal
