Water Damage Under Sink: Signs, Causes & Fixes

Water damage under the sink is a common household issue.

Unfortunately, it’s easy to overlook.

Unless you identify and fix it quickly, it can lead to bigger problems – like mold, mildew, rot, and structural damage.

Here at ServiceMaster of Lake Shore, we specialize in helping customers address water damage all throughout Chicago, and we’ve compiled our top tips into this helpful blog.

Causes of Water Damage Under the Sink

 1. Leaky Pipes

Signs:

• Visible drips or puddles under the sink.
• Dampness or a musty smell coming from the cabinets.

Steps to Fix it:

1. Examine the pipes for any visible cracks or loose connections.
2. Tighten any loose joints with a wrench.
3. Apply pipe tape or joint compound to minor leaks.
4. Consider calling a professional plumber for replacement if the pipes are significantly damaged.

2. Clogged Drains

Signs:

Signs of a clogged drain include slow-draining water, gurgling sounds, or an unpleasant odor from the sink.

Steps to Fix it:

1. Use a plunger to try to dislodge the blockage.
2. Pour a mixture of baking soda and vinegar down the drain to break up minor clogs.
3. If the blockage persists, use a plumber’s snake to clear the drain.
4. For severe clogs, enlist the help of a professional to avoid damaging the pipes.

3. Faulty Seals or Gaskets

Signs:

Water leaking, particularly around pipe joints or connections, and forming wet spots around the affected areas.

Steps to Fix it:

1. Inspect seals and gaskets for visible wear or deterioration.
2. Replace worn-out gaskets or seals with new ones. Ensure that they are correctly fitted and secured.
3. Ensure all connections are tight and not overtightened, which can damage the seals.

4. Condensation

Signs:

Condensation may cause water droplets to form on the outside of pipes, especially in humid environments.

This can lead to moisture accumulation under the sink.

Steps to Fix it:

1. Improve ventilation under the sink by installing air vents or using a dehumidifier.
2. Insulate cold water pipes to reduce the formation of condensation.
3. Regularly check and maintain surrounding humidity levels.

5. Worn-out Faucet or Hose Connections

Signs:

Dripping water from the base of the faucet or hose connections can indicate wear and tear and the potential for water damage.

Steps to Fix it:

1. Tighten loose hose connections.
2. Replace worn-out washers in faucets or hoses as needed.
3. Consider updating old faucet models to newer, more durable models that can prevent future leaks.

Addressing Water Damage Under the Sink

After fixing leaks or clogs, follow these steps to repair water damage under the sink:

1. Inspect for Mold or Mildew

• Use a flashlight to examine the area for any signs of mold or mildew, such as discoloration or musty odors.
• Wear protective gloves and a mask to prevent inhaling spores or coming into contact with mold.
• If mold is present, consider using a commercial mold remover or hiring a professional for severe cases (for more information, consult our guide on identifying and treating mold).

2. Dry Out the Area

• Remove any personal items to provide better access to the space.
• Use towels or a wet vacuum to soak up excess moisture and standing water.
• Set up fans or a dehumidifier to circulate air and reduce humidity levels to dry the area fully.

3. Remove Standing Water

• Use a wet vacuum or mop to eliminate any remaining standing water.
• Sop up small pools of standing water with towels or rags.
• Ensure that the area is arid to prevent further water damage.

4. Apply a Waterproof Barrier

• Choose an appropriate waterproof sealant based on surface type, such as silicone sealant for areas prone to water intrusion.
• Apply the sealant along the edges and seams, especially where water leakage has previously occurred.
• Let the sealant cure fully according to the manufacturer’s instructions before returning items to the area.

5. Monitor for Future Issues

• Regularly inspect the area for any signs of new leaks or water build-up.
• Install moisture sensors under the sink that alert you to future leaks or humidity changes.
• Keep the area well-ventilated and periodically check plumbing fixtures to prevent recurrence.
