Common Causes of Mold Under Sinks

Whether it is caused by a leaking sink or other plumbing issues, mold underneath sinks in your home in Fallbrook,CA  can be difficult to spot until major damage has occurred. However, knowing common causes of mold growth under sinks can make it easier to take preventative steps.

1. Leaks

Mold requires access to organic material and water in order to thrive, and when a pipe is leaking, this creates an excellent environment for mold to grow. Mold can grow on various areas under sinks and can grow in a span of only one or two days in the right conditions. In order to prevent mold from causing major damage, it’s often helpful to fix the leak as soon as possible.

2. Issues with Appliances

Though a leaking sink can, of course, cause mold to grow under sinks, there are other plumbing problems that can also result in mold growing underneath your sinks. Since sinks are often placed near other appliances in bathrooms or kitchens, it’s possible that water is coming from leaks in other appliances, such as from a dishwasher. Additionally, if the sealant wears down over time, loose caulk could allow for water to drip underneath the sink.

3. High Humidity

Sinks are generally necessary in kitchens and bathrooms, but these areas in the home are often the perfect places for mold to grow. In bathrooms, humidity levels rise when someone takes a warm bath or shower, and in kitchens, humidity levels are higher when food is boiled or steamed. To keep the humidity at an acceptable level to prevent mold growth, it’s often wise to use dehumidifiers in these areas.

Understanding that a leaking sink, faulty appliances and high levels of humidity can cause mold to grow under sinks should make preventing mold easier. However, if your home is experiencing major mold problems, consider contacting mold remediation professionals.
