Garage Door Thresholds
It’s that time of year to begin your preparations for the upcoming winter months. Sealing your garage door should be high on your list of to-do’s. Most garage door floors are not perfectly even, leaving gaps between the bottom of the door and the cement. Even small gaps, less than an inch, can lead to serious problems. Rodents and insects can enter your garage, and leaves, dirt and debris can blow in. Rain and melting snow can run in causing all kinds of hazards. If you are using your garage for an activity room or shop, a gap allows the warm air to escape and cold air to enter, increasing heating costs. A gap along the garage floor also takes away from the curb appeal of your home. Garage door thresholds can solve all of these problems. They are inexpensive, easy to install and come in a large variety of sizes and models. You can purchase them at local hardware stores, online, or from your garage door dealer. But, it’s important that you do your homework and prep before installing garage door thresholds.
Here are a few tips that might help you:
Begin by measuring the gap. Typically there will be more than one problem area so take measurements along the entire gap to insure the threshold will completely seal the gap. You might need a taller threshold depending on the severity of the problem. Many makes and models are available.
Next, measure the width of the garage door. Once you have determined the size, choose a threshold that will give you the best results. Do your homework.
Before installation there needs to be some prep work done. Most seals come in a roll. Unroll the seal and let it sit for a few days to help it flatten out. If it is extremely cold outside unroll the threshold where it is warmer such as inside your home or in the sunlight. The next step is cleaning the garage floor. Power-washing works best along with soap and water to remove any oils. Let the floor dry completely. Fill any cracks then rough up the surface with a wire brush.
Now it is time to cut the threshold to make a perfect fit. Most thresholds can be easily cut with a utility knife. Open the garage door and center the threshold between garage door tracks. Trim to fit. Remember that the hump or raised portion of the threshold goes on the inside of the door. Now lower the garage door to rest on top of the threshold. Make sure the threshold fits snuggly against the back of the door. With a pencil, mark the floor from one end to the other. Have your partner hold the threshold down while you open the garage door. Without moving the threshold mark the outside length.
Garage door thresholds need to be sealed properly to ensure the hold. Most companies will sell you a small tube of the adhesive caulk. We recommend buying an extra tube or better yet getting a large tube which can be used with a caulking gun. The small tubes can be difficult to squeeze. Using a caulking gun makes applying the caulk much easier and more accurate. Follow the instructions that come with the particular threshold you are using. They do vary according to whether your garage floor is raw concrete, sealed or painted. Again do your homework before applying. Once the threshold is placed on the glue it is difficult to move and can cause the threshold not to seal properly.
Solicit the help of another person. With your partner, carefully press on the threshold beginning at one end and working to the next. Stay within the pencil lines. Push down firmly and make adjustments quickly. Once you have set the threshold, close the garage door and inspect it carefully. Keep the garage door closed for 24 to 48 hours. To properly seal the threshold needs constant pressure until it is completely set. Do not drive on it until it is dry.
Installing garage door thresholds has many benefits both in the winter and the summer months. These benefits include keeping your garage clean, dry and protected from rodents and bugs.
