If you feel a draft, your bottom astragal seal is allowing air to pass through.
A bottom astragal is an essential part of your garage door. Bottom astragal seals help you maintain your garage door and protect the items in your garage. Installing and maintaining a bottom seal is also a cost-effective solution for conserving energy.
The bottom astragal seal keeps water, debris and drafts out of your garage. Combined with seals on the top and sides of your garage door, the seal helps insulate your space. You’ll notice the difference when less warm air escapes during colder months and when your garage retains cool air during the summer.
Using bottom astragal helps lower any energy costs associated with heating and cooling your garage. Bottom astragal that conforms to uneven concrete has a more airtight seal, so pliable materials are the best options. Two of the most common astragal materials are rubber seals and vinyl seals. Both rubber seals and vinyl seals can sustain damage over time, and they must be replaced to avoid more significant problems.
notice the difference
Astragal seals show visible signs of wear after years of exposure. Environmental conditions, material and other factors affect how often you need to replace your bottom garage door seal. Harsh conditions like heavy rain, extreme cold and temperature fluctuations speed up the process. Fortunately, worn bottom seals present noticeable signs of needing repair or replacement.
You may need to look into garage door bottom seal services if you experience one of these six signs:
If you feel a draft, your bottom astragal seal is allowing air to pass through.
Seeing cracks and other damage means your seal is weathered from exposure and should be replaced.
If the garage’s temperature feels like the weather outside, you’re losing warm or cool air and the money it takes to run your heating and air conditioning unit.
When you see sunlight between the floor and your seal, it’s time to replace your bottom seal with new material that reaches the floor.
Moisture in your garage causes metal on or around your garage door to rust when the astragal seal stops working properly.
