Sticky doors are a common problem in Australian homes. But they are easy to fix.
If you leave your sticky door, it gradually becomes harder to open, which damages the hinges and the handles and you will be up for a much greater cost if you have to replace everything.
The two main reasons for sticky doors are loose hinges and unsealed top and bottom of the door, causing swelling of the timber during wet weather. Sometimes a sticky door can also be an indication of more serious foundation issues, such as subsidence.
This particular door is binding at the bottom because of the moisture and the top because of the loose hinge.
1. Plane door down to correct height. Plane it from one side to centre. Then again from other side to centre so you get an even surface. It stops ends blowing outside the door. The ideal gap between the door and the door jam is 2 to 3mm.
2. Sandpaper the perimeter of door giving it a nice smooth round edge.
3. Seal it up with some paint, to stop moisture getting inside the door and it will remain stable.
4. If hanging the door by yourself, use this trade secret. Put hammer down on the floor parallel to the door. At a 90 degree angle, place your chisel over the top of the hammer and under the door. You have created a foot operated lever to lift the door up and down by yourself.
