Assessing the Current Garage Door Seal

Inspecting your garage door seal is the first step in determining whether it needs replacement. By identifying damage and wear, you can ensure an effective and long-lasting solution. Here’s how to assess your current garage door seal:

  1. Visual Inspection: Start by visually examining the seal for any visible signs of wear, such as cracks, tears, or gaps. Pay close attention to the bottom and sides of the garage door.
  2. Physical Examination: Run your hand along the seal to feel for any irregularities or damage. Note any areas where the seal feels brittle, loose, or worn out.
  3. Check for Drafts: On a windy day, stand inside the garage and close the door. Feel for any drafts seeping through the seal. If you notice a significant airflow, it’s a sign that the seal is compromised.
  4. Water or Pest Intrusion: Inspect the garage for any signs of water leakage or pest presence. If you notice water puddles or evidence of pests like insects or rodents, it indicates that the seal is no longer providing adequate protection.
  5. Energy Efficiency: Assess your energy bills. If they have been consistently higher than usual, it could be a result of a faulty garage door seal. A deteriorated seal allows heat or cold air to escape, leading to increased energy consumption.
