Garage door seals provide extra protection for the contents of your garage against wind, rain, dirt and rodents. They are made to withstand the pressure from the opening and closing of the garage door and also act as a cushion. Overall, the primary job of a garage door strip is to protect against the elements and pests. As robust and hardworking as the garage door rubber seal is, it does have a lifespan and won't last forever.
Ideally, you should check your garage door weather stripping every year as the longevity of a garage door seal depends on factors like usage and climate. The weight of the garage door means the seal is subject to constant pressure as it is crushed when the door closes. So in the long run, excessive use will reduce the life of the seal. The sun also damages the rubber seal over time and depending on where in the world you live, you may need to replace your garage door bottom seal sooner than most.
Catching any early signs of damage is the best way to enjoy a functioning garage that protects the contents against the elements. So how do you know when your garage door rubber seal needs to be replaced? Here are a few signs to look out for to help you know when it’s time for a new garage door bottom seal.
Sometimes it’s not easy to spot the first signs of damage to the garage door strip until it becomes visibly obvious. Small gaps in the seal may be undetectable to the eye but signs like a change in temperature or visible dirt can indicate the presence of a draught. The draught will blow cold air and dust from outside into the garage. Seeing leaves and bugs inside your garage is a sure sign that gaps are appearing in the garage door seal.
A new garage door weather strip springs back into its original shape after use and seals the door when closed. When the rubber seal ages, it becomes rigid and no longer regains its shape, becoming bent and warped over time. This is usually one of the first visible signs that the garage door rubber seal should be replaced.
Hot climates can affect the rubber seal as the sun dries out the oils in the rubber and causes it to become brittle. Chemical spills in the garage that reach the door seals will also dry out the rubber causing it to split and crack. By the time cracks have appeared, the garage door seal strip is no longer functional.
You may see small bits of your garage door strip on the floor of the garage as it crumbles away every time the door closes. This means the rubber seal has become very stiff and weak and is no longer able to perform its job effectively. Ignoring this problem could lead to a damaged garage door as small bits of rubber debris can get into the mechanism causing malfunction.
It’s recommended that garage door rubber seals are replaced at the first sign of damage so that your garage door remains protected. A gap forming somewhere along the seal is one of the first indications to replace the garage door bottom seal.
You can check the seal on your garage door in these ways :
Perform a visual inspection. Look along the length of the seal for visible gaps. Use a light source on the outside of the garage door and with the help of a friend, get them to notice if any light can be seen from the inside. Any signs of light coming through will indicate a gap in the seal.
Use a piece of paper to search for draughts. Place a piece of paper on the floor against the bottom of the door. Any movement of the paper will mean the air is entering through a gap in the seal.
Simulate rain by spraying water from a hose against the seal on the outside of the door. Look to see if any of the water makes its way past the garage door seal strip and this will highlight any gaps in the seal. This check can also be done after rainfall to make sure the seal is maintaining its integrity.
