The surface on which new kitchen cabinets are installed should be as level as possible to ensure proper and stable installation. The levelness of the surface is crucial because it affects the alignment, functionality, and longevity of the cabinets. Here are some general guidelines for the levelness of the surface:
Flatness: The surface should be as flat as possible, without any significant bumps, dips, or uneven areas. Cabinets are designed to sit on level surfaces, and any irregularities can lead to stability issues and misalignment.
Level Variation Tolerance: While it is essential to aim for a level surface, a certain degree of tolerance is acceptable. Industry standards often allow for slight variations, such as up to 1/8 inch (3.2mm) over a 10-foot span. However, keep in mind that the more level the surface, the better the overall installation will be.
Adjustments: Most kitchen cabinets come with adjustable feet or legs to compensate for minor irregularities in the floor. These adjustable features help the installer level the cabinets and make them stable even on less-than-perfect surfaces.
Preparing the Surface: If the floor or wall is severely uneven, it may be necessary to address the problem before installing the cabinets. This could involve using leveling compounds to even out the floor or adding shims behind the cabinets to adjust for any wall irregularities.
Professional Installation: For a seamless and well-aligned installation, it is often best to hire a professional contractor or installer with experience in setting up kitchen cabinets. They have the expertise and tools to handle any leveling challenges and ensure a high-quality installation.
Remember that proper leveling is not only essential for the cabinets themselves but also affects the functionality of drawers, doors, and appliances. If the surface is significantly uneven, it can lead to operational issues and premature wear on cabinet hardware.
Before proceeding with the installation, it's a good idea to thoroughly inspect the surface where the cabinets will be placed. If you have any concerns about the levelness or flatness of the area, consult with a professional to address the issue before starting the installation process.
