Main Types of Garage Door Bottom Seals

A well-fit garage door bottom seal is essential for keeping out water, blocking pests, reducing dust and debris, and improving energy efficiency by helping to maintain a consistent temperature. A few common types of weatherstripping include:

T-Style & P-Style Bulb Seals – Also known as tube seals, these are designed to fit into a T-shaped double-channel retainer on the bottom of the door. Flexible and durable, these seals provide a tight fit to block out water and debris, making them a popular option for residential garage doors.

Their rounded, bulb-like shape compresses to form a tight seal. They’re ideal for uneven floors and provide a strong barrier against drafts and pests. P-Style seals are the same, except they fit into a P-shaped retainer.

Beaded U-Shape Bottom Seals – These wrap around the bottom of the garage door and, like bulb seals, also work well on uneven pavement. Though U-shaped when installed, the seal flattens against the concrete when the garage door is closed.

U-shaped seals are great for cold climates because of the small, raised beads that hold sections of the seal just above the ground and prevent it from freezing solid.

Weatherstripping and types of garage door bottom seals

Other less common types of garage door bottom seals are J-Shape, which features a j-shaped rubber seal in a single retainer along the bottom of the door, and threshold seals, which are attached directly to the concrete under the door. We can help you find the best option for your home.

When to Replace a Garage Door Bottom Seal

Over time, even the best seals can wear out and lose their effectiveness. Here are some signs that indicate it’s time to replace your weatherstripping:

There are visible cracks, tears, or splits in the seal, which will compromise its ability to block out the elements
You notice dampness, mold, or water pooling inside your garage after it rains
Your garage feels draftier than usual or your energy bills have increased unexpectedly
The bottom seal is brittle or cracked due to freezing weather
