How Do I Know If My Door Is Properly Balanced?
You can perform a simple DIY garage door balance test. First, close the door and detach the automatic opener. From the middle of the door, lift it half way up and let it go. Be prepared to catch it if it falls too swiftly. If it does, the tension is too weak. If the door rises when you release it, then the tension is too great. You will know if your garage door is balanced if it stays put when you let go.
