The problem with your creaky door is merely oiling. One of the things that you need to use in order to deal with this problem once and for all is petroleum-based oil. Once you have got this lubricant in your hand, the first step is to spray it on the hinges of your door. Keep opening and closing the door severally. In case the squeaky voice won’t end, try applying the lubricant while the door is only partially closed.

You will notice that the creaky sound will have ended. Alternatively, make use of elbow grease. In this case, you have to remove each of the hinges’ pins. Then, clean both the pins and hinges using a cloth. After that, lubricate the hinges inside before replacing the pins. Do the same thing to all the other hinges. After trying to open and close the door a few times, the creaky should be there no more.
