Garage Door Seals

Garage door seals help close gaps around your garage door, reducing the amount of rainwater, draughts, dust, leaves and other debris that can enter. They can also help reduce potential entry points for unwanted pests.

What are
Garage Door Seals?

Garage door seals are fitted to a garage door or along the floor beneath it to help close gaps between the door and the surrounding surface.

Different seals are designed for different applications. Rubber garage door seals provide a continuous rubber edge, while brush strip seals use flexible bristles to make contact with the surrounding surface. Floor threshold seals sit on the ground beneath the closed door to create a raised barrier.

The right choice depends on the position of the gap and the type of protection you need.

Why Are
Garage Door Seals Important?

Even a small gap beneath or around a garage door can allow unwanted materials and air to enter. A suitable seal helps reduce these problems and keeps your garage better protected.

Garage door seals can help with:

  • Rainwater: Reduce water entering through small gaps beneath your garage door
  • Dust and Debris: Help limit the amount of dust, leaves and dirt that enter the garage
  • Draughts: Reduce airflow entering through gaps around the sides and bottom of the garage door
  • Pests: Help close potential entry points for mice, insects and other unwanted visitors

The effectiveness of a seal depends on choosing the right type and fitting it correctly

Brush Strip vs.
Rubber Garage Door Seals

Brush strip and rubber garage door seals work in different ways. Brush strips use flexible bristles, while rubber seals provide a continuous rubber edge. Neither is automatically the best option for every garage.

Your choice depends on the size and position of the gap, the surface the seal needs to meet and the problem you want to address. For example, a floor threshold seal may be worth considering when the main issue is a gap where the closed door meets the floor.

How to
Seal Gaps Beneath Your Garage Door

If you notice daylight beneath your garage door, or find water and debris collecting inside, it may be worth checking the gap and the condition of your existing seal.

For gaps beneath the door, there are two main options: a rubber seal fitted directly to the garage door or a threshold seal installed along the garage floor. Which option is suitable will depend on the size of the gap, how the door closes and the condition of the floor.

For more information on choosing between these options, read our blog on how to seal the bottom of a garage door.

Can Garage Door Seals Help
Prevent Pests?

Gaps beneath and around garage doors can provide potential entry points for mice, insects and other unwanted pests. Worn seals, uneven floors and openings around the door frame can all leave spaces that may need attention.

Choosing a suitable garage door seal for pest prevention can help close these gaps and reduce potential entry points. Formseal offers brush strips, rubber garage door seals and floor threshold seals for different applications. However, sealing alone may not resolve an existing infestation, so it is also important to check other openings and keep food and waste securely stored.

How to Measure a
Replacement Garage Door Seal

Before ordering a replacement seal, check the length required and the dimensions of the existing seal or carrier. You should also measure the gap the seal needs to cover to help ensure the bristles or rubber make suitable contact.

For brush strips, the bristles should reach the surface without bending excessively. Checking the carrier dimensions and how it attaches can also help you identify a compatible replacement.
