Why Mold Grows Under the Kitchen Sink

The kitchen sink is a high-use area with frequent exposure to water. Over time, small leaks, condensation, or poor plumbing can lead to a moist environment that invites mold to grow. Here’s why the space under your kitchen sink is especially vulnerable:

• Undetected Leaks: A slow drip can go unnoticed for weeks or months

• Humidity & Steam: Hot water use raises humidity levels

• Darkness: Lack of light encourages mold spores to multiply

• Clutter: Stored cleaning products and sponges trap moisture

• Lack of Ventilation: No air circulation to dry the space

If you open your cabinet and see discoloration or smell mildew, don’t ignore it. Call (575) 623-0993 to schedule a mold inspection with Pro Steamer.

How to Spot Mold Under the Sink

Mold under the sink doesn’t always show up as the obvious black stuff. Here’s what to look for:

Visual Signs

• Black, green, or gray patches

• Fuzzy or slimy texture

• Peeling paint or bubbling surfaces

Smells

• Musty, damp, or earthy odor

Moisture Issues

• Warped wood, wet cabinet floors, or water stains

Health Symptoms

• Sneezing, coughing, itchy eyes, or worsening allergies when near the sink area

If you’ve noticed any of these signs, contact Pro Steamer at (575) 623-0993 for expert evaluation and mold testing.

Is Mold Under the Sink Dangerous?

Yes. Even a small mold patch can pose health risks and cause long-term damage.

Health Hazards Include:

• Respiratory issues (coughing, sneezing, asthma flare-ups)

• Headaches or fatigue

• Skin and eye irritation

• Potential neurological symptoms with prolonged exposure to black mold

Structural Damage:

Mold eats away at wood, drywall, and particleboard, compromising the integrity of your cabinets and flooring. The longer it stays, the worse it gets.

Don’t risk your health or your home’s structure. Call (575) 623-0993 and let Pro Steamer take care of the mold safely and effectively.
