Protecting Cabinets From Water Damage

Water damage is nothing to mess around with. It can quickly ruin your cabinets, floors and walls. The hardest part…it often goes un-noticed until it’s too late.

If you don’t have a small barrier or protection in your cabinet base it can destroy laminate and finishes, cause warping and even bring about mold.

Along with under sink cabinet protector mats, there is waterproof paint claims to help against any moisture penetration. One of the easier ideas to protect your cabinets from water damage is to use a sensor that sits inside the base of the cabinet. An alarm sounds off when water starts to collect and is detected by the sensor.

Do You Have a Leak?

  • Check your cabinet floor for any dark spots or discoloration
  • Feel around plumbing pipes and hoses for moisture
  • Check the smell for anything odd

It’s also important to check under sink hoses and pipes for any loose connections and shoddy plumbing work. 

How to Choose the Right Under Sink Protector Floor Mat

As I frequently discuss on this website, it’s all about the measurements and functionality. This goes for choosing the best floor mat to protect against water damage. Assuming water damage has not already occurred and you want to protect your cabinets from future issues, you’ll want to empty out the under sink space and follow these steps…

  • Clear the cabinet space you want to put a mat into
  • With a tape measure, gather the width and depth dimensions of the cabinet
  • Most widths for under sink kitchen cabinets will be 30″, 32″, 34″ or a 36″
  • Make sure the floor mat product will not interfere with cabinet hinges (most will not, as they sit below hinge height)
  • Choose from rubber or plastic material floor mats
  • Do you have any pipes coming through? You’ll need to measure and prepare to cut the floor mat to accommodate those pipes

Can You Install a Slide Out Organizer on a Mat?

There’s lots of amazing and easy to install under sink pull out organizers. The question is though…can you install one on top of a cabinet floor mat? The answer is a tough one. It simply depends on the slide out and the type of floor mat.

Generally, the slide out will need room to operate and “slide” out of the cabinet. The slides and base frame of the pull out also need to be mounted to the cabinet floor through the cabinet protector mat.

If you have a thicker cabinet protector mat, it may be difficult to use a slide out organizer in your base under sink cabinet.
