Water Under Your Kitchen Sink? It’s Easier To Fix Than You Might Think!

Have you recently discovered water under your kitchen sink? Perhaps you have recently begun to smell something funky in your kitchen? If so, then you are not alone. Leaking kitchen sinks are a very common household maintenance issue. And, the good news is that leaking sinks are typically an easy thing to fix.

Follow these three steps to successfully fix your sink's water leak:

Step 1: Locate the Leak

To find the exact location of the leak, start by opening up the cabinet below your kitchen sink. Remove anything that you are storing in there, so that you will have adequate room to work.

Turn on the water and watch to see if you can find any water drips on the underside of the sink, or coming from the plumbing.

If a leak is small, then you may have trouble locating it. To help you, make a mixture of:

  • 1 teaspoon of dish washing liquid
  • 1 cup of water

Using a sponge, rub the soapy water on the pipe under the sink.

Turn the water back on and watch for bubbles in the soapy water.

This technique will assist you in finding even the smallest leaks.

If you do not see any leaking water, then it is possible that the caulking around your sink is leaking. This will cause water in the cabinet when too much water builds-up on the kitchen counter.

Step 2: Fixing a Plumbing Leak

If you have a leaking pipe, then you will need to replace the faulty pipe.

If you do not know how to make this repair, then you should contact local plumbing services to make the repair for you.

Step 3: Fixing a Caulking Leak

If you have determined that the water leak is coming from around your kitchen sink, then you will need to re-caulk the area.

To apply new caulking, simply clean the area well with soapy water. Allow the area to completely dry, for at least 30 minutes.

Carefully scrape off any damaged caulking using a sharp utility knife. Once you have done this, then you can wipe the area clean and apply a new bead of silicone caulking.


While a leaking kitchen sink can cause serious damage in your cabinet, by fixing your sink when you first discover problems you can avoid any lasting problems. All you need to do is locate the exact location of the leak and then fix the cause.

If you are unable to fix your own plumbing, then you should contact a licensed plumbing contractor in your area. This is a quick and simple fix for them to perform for you.
