Ideally, you should level your cabinets before adding the countertop. Properly leveling the cabinets provides a stable and even base for the countertop, ensuring a smooth and secure installation. Here's why leveling the cabinets is the preferred approach:
Stability and Support: Leveling the cabinets ensures that the countertop sits evenly on a solid foundation. This helps distribute the weight of the countertop and any objects placed on it evenly across the cabinets, reducing the risk of sagging or damage over time.
Preventing Gaps and Uneven Surfaces: If the cabinets are not level, the countertop may not fit flush against them, leaving gaps between the countertop and the cabinets. This can create an uneven surface and compromise the appearance and functionality of the countertop.
Easier Installation: Leveling the cabinets before adding the countertop simplifies the installation process. The countertop can be cut and fitted accurately to the level surface of the cabinets, reducing the need for extensive trimming and adjustments.
Professional Appearance: A level countertop that sits evenly on level cabinets looks more professional and aesthetically pleasing. It enhances the overall appearance of the kitchen or bathroom.
If your cabinets are not level, it's essential to address the issue before proceeding with the countertop installation. Depending on the severity of the leveling problem, you may need to use shims or adjust the cabinet legs to achieve a level surface.
Leveling the countertop and trimming it out to compensate for unlevel cabinets is not the recommended approach. It can be more challenging to achieve a precise and secure fit, and it may result in an uneven or unstable countertop surface. Additionally, trimming the countertop excessively may compromise its structural integrity and could lead to future issues.
To ensure a successful countertop installation and a long-lasting result, it's best to start with level cabinets and then proceed with fitting and securing the countertop properly on the leveled surface. If you're unsure about the process or don't have experience with cabinetry and countertop installations, consider consulting a professional installer or contractor for assistance.
