How to Shim a Door hinges
When you read through this article, you appreciate how easy and quick it is to shim a door. You only need to have all the materials ready. The process may sound technical, but we guarantee desirable results.
Step 1: Gather All the Materials You Need
You don’t want to initiate the process only to discover you don’t have some items. Therefore, we recommend that you gather all the materials required to fix your door. The good thing about these materials is that there are cheap and readily available. This means you don’t have to break your bank to purchase them. This article outlines the core materials you need to undertake the task. Here are the materials you must have;
- Nails and screws
- Nail gun
- Utility knife
Step 2: Remove the Trim
To note the root cause of the problem associated with your door, you may need to remove the trim. However, you should know that not all the doors have a trim. It mostly depends on the design of your door. This is the casing that surrounds the door. When you remove it, you have a nice view of what your door needs. Use a utility knife to break the paint seal that is in between the casing and the wall around the door.
Step 3: Discover the Root Cause of the Problem
Before you begin this process, it is important that you start by working hard to discover where the problem is. One, the problem could be that the screws applied on the hinges have become loose.
And the only way to fix this problem is by tightening them. Secondly, the problem could be the jamb itself. This could explain the reason why the door is leaning on one side. Whichever the cause, this article comes in handy to offer a practical solution to the problem.
Take time to check the vertical spacing the door and jamb. There is always a likelihood that there is a large gap at the bottom. It is a perfect indication that the door has skewed forward from top. This is common and won’t let the door shut.
Step 4: Choose the Type of Shim to Use
If you find out that there is a space between the door and jamb, then you need to shim your door. The decision on how thick your shim should be is determined by the gap between the door and jamb. Therefore, it is always advisable to take your time and measure the gaps. Preferably use a ruler instead of a tape measure.
This is because it gives you more accurate results. When choosing the shim material, thin cardboard is possibly the best choice. The good thing about this type of shim is that it won’t compress when you tighten the screws. Again, you can increase the thickness of the shim by layering pieces of cardboard on top of each other.
You can decide to go for a premade shim that can fit on the hinges on your door. They are predrilled and hence easy to use. We highly recommend this type of shim if your door is made of steel
Step 5: Install Shim
Now comes the main part of this guide. Before you kick-start this step, you should know that you can choose to install a shim between the hinge and the jamb or between the hinge and door. You have full discretion to choose how you want it. Any method you choose works perfectly. Here are the steps you should shim your door;
- Open the door. No matter how you choose to install shim, you must ensure that your door remains open.
- Wedge a piece of wood under the door. When carrying out the procedure, you don’t want disturbance. As such, it is highly recommended that you wedge a piece of wood under the door. This limits the door from moving as you unscrew the hinges.
- Remove the screws. In most cases, doors have three hinges; at the top, middle, and bottom. Using your screwdriver, remove the screws from the hinges that you would like to remove. For the middle hinge, make sure you remove it as well.
- Slide the shim behind the hinges that need extra spacing. Use your screwdriver to put the screws back and tighten them.
- Check the operation of the door. You may realize that you might be forced to add or remove the cardboard to ensure the door gets straight.
- As you make adjustments, you should always leave the middle hinge unattached. After you are sure that the door is just working fine, drive the screws of the middle hinge back. If the doors go off level, you should slide a shim that has half the thickness of the material.
- Your door should be closing normally without a problem.
Step 6: Install the Trim Back
Once you have determined that your door is just working fine, reinstall the trim back. Use a nail gun or hammer and drive the right size nails to attach the trim to the wall. This works only if your door had trim initially. If it didn’t have, there is no need to bother yourself with installing the trim back.
NB: Even though in our guide, we have mentioned the need to tighten the screws of the hinges, this does not mean that you overdo it. This is because the screws may strip if you choose to overtighten them.
The process is technical, and hence you should be extra cautious. This is because missing out on a particular step may end up ruining almost everything.
