Are you looking to install new cabinets in your home or office? Shimming a cabinet is an essential step in the installation process. Shimming ensures that the cabinets are level and properly aligned, which not only improves their appearance but also increases their durability.
Whether installing a new cabinet or correcting the tilt of an existing one, properly shimming can prevent doors from sticking, reduce the risk of damage, and ensure that the cabinet stands steadfast over time.
This guide on how to shim a cabinet, will walk you through the process of selecting the suitable materials, assessing the need for shimming, and applying techniques that will lead to a perfectly aligned cabinet. By the end, you’ll be equipped with the knowledge to confidently tackle this essential task.
What Will You Need?
Before you start shimming, gather the following materials:
- Level
- Shims (wood or plastic)
- Hammer
- Saw
- Utility Knife
You can find these tools and materials at your local hardware store. Select shims that are the right size for your cabinet installation.
10 Easy Steps on How to Shim a Cabinet
Step 1. Prepare the Cabinet Area:
To begin, clear the installation area of any debris or obstacles to ensure a safe and tidy workspace. The floor beneath the cabinet must be clean and level; use a level to assess this. If there are any variations in the floor height, note the areas that may require additional shimming.
Additionally, check the wall against which the cabinet will be mounted for any irregularities that might impact alignment. If the wall isn’t straight, it may lead to gaps or misalignment once the cabinet is installed. Taking the time to prepare the area properly will set the stage for a smoother installation process and help to achieve a more professional-looking result.
Step 2. Assess the Need for Shimming:
Once the area is prepared, it’s time to assess whether shimming is necessary. Use a level to check the cabinet’s base and determine if it is sitting flat against the floor. Place the level on the cabinet top, and observe the bubble in the vial. If the bubble is off-center, it indicates that the cabinet needs to be adjusted.
Take note of which areas are high or low. For instance, if one side is lower, you’ll need to add shims under that side to bring it to level. Identifying these discrepancies early on will help guide the placement and thickness of the shims you will need to apply in the following steps.
Step 3. Cut the Shims if Necessary:
If your shims are too thick or long for the specific areas that require adjustment, use a saw or utility knife to cut them to the appropriate size. Shims are typically available in various thicknesses, so choose ones that effectively bridge any gaps without causing undue pressure on the cabinet. It’s better to start with thinner shims and stack them if necessary rather than using overly thick shims that might compromise stability.
Step 4. Position the Shims:
With the proper shims prepared, it’s time to position them. Begin by placing the shim beneath the low side of the cabinet where the level-indicated adjustments are needed. Insert the shim gently under the cabinet, ensuring that it fits snugly but does not cause any lifting until everything is aligned. Keeping the shim as flat as possible is important to maintain stability.
Step 5. Check for Level Again:
After positioning the shims, it’s crucial to check the cabinet-level once more. Place the level on the cabinet top again, paying close attention to the bubble in the vial.
If the bubble remains off-center, you may need to adjust the shims by adding or removing them as necessary. Take your time during this step; achieving a level position is pivotal for ensuring the proper functionality and aesthetics of the cabinet. If adjustments are needed, gently tap the shims with a hammer to secure them without causing damage to the cabinet.
Once you’ve achieved a level line, double-check that the cabinet aligns with any adjoining cabinets or walls to ensure a seamless look and function. This step is critical in preventing future issues, such as doors not closing correctly or cabinets appearing crooked after installation.
Step 6. Secure the Cabinet in Place:
Once the cabinet is level and the shims are appropriately positioned, it’s time to secure it to the wall.
Using a drill, attach the cabinet through its pre-drilled holes or directly into the wall stud to ensure stability. Make sure to use screws that are the correct length for your cabinet; they should penetrate into the wall stud sufficiently to hold the weight. Securing the cabinet will prevent it from shifting or becoming misaligned over time. After the cabinet is secured, double-check the level one final time to ensure that everything remains aligned during this process.
Step 7. Trim Excess Shim Material:
After securing the cabinet and confirming that it remains level, you may find that some of the shim material extends beyond the cabinet edges. To achieve a clean and professional look, it’s essential to trim any excess shim protruding from under the cabinet.
Use a utility knife or a saw to carefully cut away the extra material, ensuring you do not disturb the shims underneath. This trimming will improve the aesthetics and help prevent any potential hazards caused by exposed sharp edges. Take your time during this step to ensure a neat finish, contributing to the overall quality of your cabinet installation.
Step 8. Fill in Gaps or Spaces:
After trimming the excess shim material, you might notice small gaps between the cabinet and the wall or floor. To achieve a polished appearance, filling in these gaps is essential. Use caulk or wood filler as appropriate to seal any openings. Apply a bead of paintable caulk along the edges where the cabinet meets the wall, smoothing it with a finger or a caulking tool for a clean finish.
If there are more significant gaps that caulk won’t adequately fill, consider using wood filler to create a smooth surface. Allow any filler to dry completely according to the manufacturer’s instructions before proceeding with any painting or finishing touches. This step will not only enhance the aesthetic appeal but also contribute to the overall durability of the cabinet installation by preventing moisture ingress and potential damage.
Step 9. Sand and Paint (if needed):
Once the caulk or wood filler is dry, lightly sand any rough areas to ensure a smooth and even surface. If you use filler, sanding will help blend the repaired areas with the surrounding cabinet surface.
After sanding, clean the dust off thoroughly to prepare for painting. If the cabinet needs a fresh coat of paint or touch-ups, now is the time to apply it. Choose a paint that matches the existing finish of the cabinet for a cohesive look. Depending on your desired aesthetic, applying a top coat can add extra durability and a polished appearance to your installation.
Step 10. Final Inspection:
With the installation complete, conduct a final inspection of the cabinet. Check for overall alignment with other cabinets or structures in the area and ensure that the doors and drawers function correctly without resistance.
Examine your installation for any missed details or areas requiring touch-ups. Verifying that the cabinet is securely mounted and that all shims are appropriately positioned is crucial. Taking this time for a thorough evaluation ensures that the cabinet looks great and is built to last, fulfilling its intended purpose efficiently and effectively.
By following these ten steps, you can achieve a level and secure cabinet installation that looks great and functions correctly.
5 Things You Should Avoid
- Using Inappropriate Materials: Avoid using materials that are too thick or not durable for shimming. Shims should be made of wood or composite materials that provide stability without compressing over time.
- Rushing the Leveling Process: Take the critical step of checking for level multiple times. Rushing can lead to misalignment, resulting in later functional issues with cabinet doors and drawers.
- Overloading the Shims: Ensure you do not place too many shims under a cabinet, which can destabilize it and create unnecessary pressure points. Use just enough to achieve a level position.
- Neglecting Wall Studs: Failing to secure the cabinet to wall studs can result in instability. Always aim to attach the cabinet through pre-drilled holes into the studs to ensure it remains anchored and secure.
- Skip the Final Inspection: Skipping this step is tempting, especially if you’re eager to see the finished product. However, taking the time to conduct a final inspection ensures that your cabinet installation is of high quality and meets all necessary standards.
By avoiding these common mistakes, you can ensure a successful and long-lasting cabinet installation.
