For quartz countertops, it is crucial to have the cabinets leveled properly before installation. A level surface ensures that the weight of the quartz is evenly distributed, reducing the risk of stress points and potential cracking. Here are some guidelines on how level the cabinets need to be for quartz countertops:
Flat and Level: The top surface of the cabinets should be flat and level within reasonable tolerances. Most countertop installers prefer the cabinets to be level within 1/8 inch (3.2 mm) over a 10-foot span. This level of precision helps ensure that the countertop sits evenly and securely on the cabinets.
Shimming: During the installation process, if any sections of the cabinet's top are not level, shims may be used to raise or level specific areas. The shimming process helps achieve a uniform and stable surface for the countertop.
Structural Integrity: Beyond just being level, the cabinets should also be structurally sound and capable of supporting the weight of the quartz countertop. Make sure the cabinets are appropriately constructed and in good condition before proceeding with the countertop installation.
Professional Installation: Installing quartz countertops is a skilled job that requires precision. It is best to have a professional installer take measurements and handle the installation to ensure the best results.
Seam Placement: Depending on the size and layout of your countertop, there may be seams where two pieces of quartz are joined together. A level surface helps minimize the visibility and potential issues with these seams.
Substrate Support: In some cases, additional support may be required in areas with overhangs or heavy appliances. Your countertop installer will determine if any additional support, like brackets or corbels, is necessary based on your specific kitchen design.
Keep in mind that quartz is a heavy material, and any discrepancies in cabinet leveling can lead to problems in the long run. A well-leveled and stable cabinet surface is the foundation for a successful and durable quartz countertop installation.
Before the installation day, it's essential to communicate with your countertop supplier and installer to discuss the specific leveling requirements and any other preparations needed for the successful installation of your quartz countertops.
