The short answer
Check Under Your Sink First
Start by looking at the plumbing under your kitchen sink. A loose connection at the P-trap or a cracked supply line for the faucet can drip water that travels along pipes and collects under the island base cabinet. Feel the pipes and connections for moisture. Also, check the garbage disposal unit and its connection for any signs of a slow leak.
If you don't see an obvious leak, dry the area completely with towels. Then place a dry paper towel under the pipes and check it again in a few hours. A small, intermittent drip might not be visible right away but will show up on the paper. This simple test can help you pinpoint a hidden plumbing issue before calling a plumber.
Inspect Appliances Nearby
Your dishwasher or refrigerator might be the culprit. The dishwasher's water supply line or drain hose can develop a small leak where they connect under the sink or at the appliance itself. If your island houses a dishwasher, check its front access panel and the floor directly beneath it for pooled water.
Refrigerators with ice makers and water dispensers have supply lines that can leak. Condensation from the fridge's defrost cycle or a blocked drain pan can also cause water to drip onto the floor and flow toward the island. Pull the refrigerator out carefully to inspect the area behind and underneath it for any moisture or staining.
Immediate Steps to Take
Your first priority is to stop the water flow if you can find the source. Turn off the water supply valves under the sink or to the specific appliance you suspect. If you cannot locate a local shutoff, turn off the main water supply to your home. This prevents additional water from causing more damage while you investigate further.
Then, remove any standing water and dry the surface thoroughly with towels. Move any rugs or movable items away from the wet area. Increase air circulation by opening windows or using fans, but avoid using household vacuum cleaners on water. Acting quickly helps limit the spread of water and reduces the chance of mold starting to grow in hidden spaces.
When to Contact Water Damage Professionals
If the leak is significant, the water has spread under cabinets, or the subfloor feels soft, you likely need help from local water damage pros. They have specialized equipment like moisture meters and industrial extractors to find hidden moisture and dry the structure properly. Drying floors and walls completely is critical to prevent mold and structural rot.
Attempting a major dry-out yourself can leave moisture trapped inside walls or under flooring. The pros can also assess if any materials, like wet insulation or damaged cabinetry, need to be removed for proper drying. If you live in Boca Raton, acting fast is wise, as the local humidity can slow the drying process and accelerate mold growth.

Could this be a sign of a slab leak?
Yes, if your home is on a slab foundation, a leaking water line below the concrete could send moisture up through cracks. You might also notice higher water bills or warm spots on the floor. A plumber can perform pressure tests to check for this type of leak.
Will my homeowners insurance cover the repair?
It depends on the cause of the leak. Sudden, accidental discharges like a burst supply line are often covered, while damage from long-term neglect might not be. Policies vary, and your insurer decides what is covered. Check your policy and document the damage with photos.
How long does it take for mold to grow from this?
Mold can begin to grow on wet materials within 24 to 48 hours in humid conditions. That's why fast drying is essential. If you see or smell mold, or if materials stayed wet for days, a mold professional should inspect to see if remediation is needed.
