Even after 15 years of installing kitchen cabinets, each kitchen renovation project seems to bring new and unique challenges. While each project is different, the methods for installing cabinets remains the same. I was surprised at how many DIY'ers that were leaving messages on my blog were asking questions about how to secure the cabinets.

One of the most common mistakes that people were making, which was causing them problems, was that they were securing the sides of the cabinets to each other. While this isn't a problem with frameless cabinets, it becomes a problem with framed cabinets because of the "lip" that overlaps the sides of the cabinets. Why are frameless cabinets installed differently? First let's talk about how the cabinets are built.

Traditional cabinets with a face frame have a groove that the side panels fit into to create a stronger and sturdier cabinet. By having the face frame overlap the sides, it pevents the sides from shifting left to right, or top to bottom. While this creates a stronger cabinet, it prevents you from securing the sides of the cabinets together without using a spacer in-between.

Since kitchen cabinets are attached to the wall first and get the majority of their support from there, you really only need to secure the face frames to each other in order to create a strong horizontal support. By trying to secure the sides to each other, you can create one of two problems- either the sides will bow out and weaken the cabinet, or it will create some separation at the face frame. While this is more of a cosmetic issue, it can easily be avoided by securing the cabinets to each other through the face frame and not through the sides.

This also applies the base cabinets, which will have the same characteristics as the wall cabinets mentioned above. For frameless cabinets, they actually gain strength by securing the sides of the cabinets to each other. Without a face frame to tie everything together, they are relying on support from the back and the sides. Since they do not have the lip on the sides, they can be secured tightly together.

So if you are planning on installing your own kitchen cabinets, it is important to consider which type of cabinets you are installing(frameless or framed), and use the appropriate technique to ensure a strong bond and proper support.
