What Causes Cracks in Garage Doors?

Your garage door is a significant component of your home security and safety. But what happens when the door cracks? 

Cracks in garage doors hamilton are another issue that can startle you. Garage doors are pretty strong and should not crack if you take proper care of them. 

The problem with some garage door wires is that they begin to corrode, which causes moisture to get trapped inside the joint as water enters it at high speed. This forces the wires to buckle, causing stress and leading to cracks in your garage door.

If you’ve noticed cracks in your garage doors, you’re probably wondering what causes them. The benefit of a garage door is a heavy, serious piece of machinery used daily by you and your family. This makes it essential that you keep it in top condition. 

Cracks in Garage Doors

Below we have is the list of the reasons for garage door cracks:

  • Changes in Temperature

The garage door is a mechanical system designed to function at a specific temperature. When the temperature outside changes, the garage door also needs to change its operation. If the temperature outside is constant and does not change, then there is no need for adjustment.

But if you keep seeing cracks on your garage door, it is probably due to temperature changes. The garage doors may start cracking due to rapid temperature changes. 

The cold and hot summer months can cause your garage door to expand or contract. This is due to the difference of outside and inside temperatures. This expansion and contraction can cause cracks in your garage door.

  • Water

Water is the most common cause of cracking in garage doors. The water can come from rain or snow or from condensation when you leave your garage door open overnight. 

Water drips down the track and onto the garage floor can cause rusting and corrosion. If you have a garage door opener, this may also lead to problems with the motor.

If your garage door has been exposed to a lot of rain, you will likely have to replace the door. The weight of the water can cause the expansion and contraction of wood, which can lead to cracks.

  • Uneven Settlement

Cracks in garage doors are usually caused by uneven settlement, meaning the settling process has not been completed. It’s important to note that a garage door is designed to be able to handle a certain amount of weight and force.

If you live in an area with clay soil, your garage door may settle unevenly, leading to cracks in the door frame or other parts of the structure.

Moreover, it can happen if you have an unevenly loaded door or live in an area with a high amount of settlement.


With preventative maintenance and care, garage door cracks shouldn’t be all that common.The key is to regularly inspect your door, as minor problems can quickly turn into larger ones if left unchecked. 

If you see cracks or other signs of wear, contact your local garage door specialists for a professional inspection. You don’t want to let those problems get out of hand.
