Measuring The Garage Door
Determining the size of the garage door
Before you can install a garage door seal, you need to determine the size of your garage door. This step is crucial to ensure that the seal fits properly and effectively keeps out drafts, pests, and debris. Measuring your garage door may seem like a simple task, but it requires accuracy and attention to detail. Here’s how you can easily determine the size of your garage door:
Taking accurate measurements for the seal installation
When it comes to installing a garage door seal, taking accurate measurements is key. You want to make sure that the seal fits snugly and tightly along the bottom of the door, leaving no gaps for air or water to seep through. To ensure accurate measurements, follow these steps:
- Use a tape measure to measure the width of the garage door from one side to the other. Start at the left edge of the door and measure all the way to the right edge. Write down this measurement.
- Next, measure the height of the garage door from the bottom to the top. Begin from the inside of the door, where it meets the ground, and measure all the way up to the highest point of the door. Note this measurement as well.
- It’s also important to measure the thickness of the bottom edge of the garage door. This measurement will help you determine the type of seal you need, as there are various options available for different door thicknesses. Use a caliper or measuring tape to measure the thickness and write it down.
By taking these accurate measurements, you can ensure that the garage door seal you choose is the right size for your door and provides a proper seal when installed. Once you have these measurements, you can confidently proceed with the installation process knowing that the seal will effectively keep out unwanted elements.
Inspecting The Existing Seal
Inspecting the Existing Seal is an essential step before installing a new garage door seal. The condition of the existing seal can affect the effectiveness of the new seal and ensure a proper fit. It is important to check for any damage or wear in the existing seal and assess its overall condition. Let’s dive deeper into these steps and understand how to inspect the existing seal.
Checking for any damage or wear
Begin the inspection process by carefully examining the existing garage door seal for any signs of damage or wear. Look for any cracks, tears, or breaks in the seal that may compromise its ability to keep out external elements such as dust, water, or drafts. Pay close attention to the bottom edge of the seal, as this area often experiences the most wear due to frequent contact with the ground and movement of the garage door.
If you notice any damage, it is crucial to replace the seal as soon as possible. Damaged seals not only fail to effectively seal your garage door but can also lead to energy loss, reduced insulation, and increased risk of pests infiltrating your space.
Assessing the condition of the seal

Once you have checked for damage, take a closer look at the overall condition of the existing seal. Evaluate its flexibility and elasticity by gently pulling and stretching it. A well-maintained garage door seal should still retain its flexibility, allowing it to conform to the movements of the garage door as it opens and closes.
If the seal feels stiff, brittle, or shows signs of cracking when stretched, it is a clear indicator that it has reached the end of its lifespan. In such cases, replacing the seal is necessary to ensure optimal performance and protection.
You should also inspect the seal for any discoloration or signs of deterioration. Exposure to sunlight, extreme temperatures, and other environmental factors can cause the seal to deteriorate over time. Discoloration may indicate that the seal’s material has degraded, making it less effective at creating a tight barrier against external elements. In these instances, replacing the seal is highly recommended to maintain the integrity and functionality of your garage door.
Inspecting the existing seal is a crucial step in the process of installing a new garage door seal. By carefully checking for any damage or wear and assessing the overall condition of the seal, you can ensure that your new seal will provide maximum protection and energy efficiency for your garage space.
Removing The Old Seal
Before installing a new garage door seal, you’ll need to remove the old one. This step-by-step process will guide you through the removal without causing any damage to your door.
Step-by-step process for removing the old seal
- Gather the necessary tools: Before getting started, make sure you have the right tools on hand. You’ll typically need a utility knife, pliers, and a screwdriver.
- Identify the type of seal: Inspect the seal on your garage door to determine its type. Depending on the model, it might use a bottom seal, weatherstripping, or threshold seal. Knowing this will help you proceed with the removal process.
- Clean the area: Before removing the old seal, it’s essential to clean the area thoroughly. Use a brush or vacuum to remove any dirt, debris, or adhesive residue that may have accumulated over time.
- Start from one end: Beginning at one end of the door, use a utility knife to carefully cut the seal. If it’s a bottom seal or weatherstripping, cut along the bottom edge of the door. For threshold seals, cut along the sides and bottom.
