Using a shim in window and door frames.
Once you have the door frame or window installed and notice that there is a gap, get the shims ready.
Place a wooden shim into the space between the door casing/window and the framed area.
Using a hammer, gently tap on the shim until it pushes into place. You can use a spirit level to ensure that the window or door frame is level.
If you find that 1 wooden wedge isn’t enough, you can insert another wedge by tapping it into the space right next to the first shim, except the other way around (now the shims are top and tail). To ensure that the shim stays in place, use a set of securing screws.
If there is a piece of wedge sticking out, score and break it off using a utility knife.
Using a shim to fix wobbly fence posts.
Sometimes wedge posts and panels become loose and wobbly. The fence can begin to lean or worse; make an annoying creaky sound. You can use a wooden wedge (or a few) to fix this.
First, push the fence post into the correct position and note where the loose space or gap is.
Now, take your shim/s and push it into the space. You may need to use a few shims and you may need to hammer or tap them in.
Using a wooden wedge or shim to fix wobbly and uneven furniture
If you have furniture that stays in a fixed place, but wobbles when used, you can fix it with a wooden wedge shim.
First, wobble the table so that you can see which leg or foot has a gap between it and the floor.
Then, place a wooden wedge under that foot and test to see that the table is sturdy and level.
Now, while the furniture is still standing on the shim, use a pencil to trace the outline of the foot or leg onto the shim. You can have the shim cut into that shape before you affix it permanently to the furniture leg or foot.
You can use double-sided tape or glue to attach the shim to wooden furniture.
