Finding mold under your sink can be unexpected and unpleasant news, but luckily, you can remove it yourself. Black mold under the sink is unattractive and can be a health hazard. The area under your sink is a notorious breeding ground for mold. With its dark, damp environment and potential for water leaks, it’s no wonder that unsightly mold often takes up residence in this tucked-away space.
While mold growth can be concerning, tackling it under your sink doesn’t have to be daunting. If you find mold under your sink, you should start fighting it immediately to keep your home clean and safe. Leaving mold untreated can allow it to grow and spread.
The Black Mold Menace
Understanding why black mold is dangerous is essential before going through the whole procedure for mold removal. Black mold thrives in humid areas, such as bathrooms, basements, and those under sinks. When water leakage or moisture becomes a perpetual issue, the conditions are perfect for mold spores to germinate and grow into dangerous colonies. These microscopic spores can become airborne, leading to potential respiratory problems for those exposed to them for a long time.
Why Black Mold Flourishes Under The Sink
Several reasons lead to the flourishing of black mold under your sink:
Water Damage: Leaks from pipes, faucets, or dishwasher hoses primarily cause moisture buildup. Over time, even small leaks can lead to a significant mold problem.
Humidity Levels: Kitchens and bathrooms are places where people cook, wash, and bathe, which generates higher humidity. The space under the sink is closed, creating the best environment for mold growth.
Poor Ventilation: If proper ventilation or airflow is absent, moisture can become trapped under your sink, fostering the growth of mold.
Wood and Drywall: Wooden cabinetry or drywall behind the sink will foster fungus growth if it is damaged by water. Mold spreads rapidly on such surfaces, making the problem worse.
How To Inspect For Mold Under The Sink
The first step in dealing with black mold is inspection. Here’s how to carry out a good inspection of your under-sink area:
Look for Visible Mold: Mold is usually black, green, or even gray and can appear as patches or spots on surfaces like wood, pipes, or walls.
Check for Water Damage: Inspect the pipes for any signs of leaks or moisture. Water stains or swollen cabinet doors usually indicate water damage, which may encourage mold growth.
Odor: A musty smell is a common indication of mold. If the smell under the sink goes beyond bacteria, it may be due to mold and bacteria growth.
Look for Bacteria: While mold is mold, bacteria can live in the same conditions, again causing your home to smell awful and bringing dirt into other areas.
Items You Need For Cleaning Mold
Before you start, gather the essential gear everything you need for this job. Here are some recommended items for cleaning mold:
- Respirator
- Eye protection, glasses (recommended)
- Rubber gloves
- Oxygen bleach or cleaning solution
- Water
- Sprayer
- A stiff brush
How To Remove Mold Under the Sink
A Hidden Hazard Black mold thrives in damp, dark environments, making the area beneath sink cabinets a prime location. Mold can appear anywhere in your home, but you often find it under sinks where leaks and humidity are common. Here’s how to remove mold under the sink and keep it from returning.
1. Address the Root Cause
Even the cleanest homes can harbor mold under the sink. To effectively eliminate it, start by identifying and fixing the source of moisture. Any cleanup effort will only provide a temporary solution without solving the underlying issue. Here are common causes of moisture under the sink:
- Pinhole leaks in sink drain pipes
- Worn washers on shut-off valves
- Leaky plumbing behind cabinet walls
- Faulty garbage disposal housings or connections
- Old or deteriorating dishwasher water lines
Once you’ve pinpointed the cause, determine if it’s a repair you can handle yourself. If it’s beyond your expertise, call a licensed plumber to ensure the issue is resolved properly. Only then should you move on to mold removal.
2. Select Your Mold-Fighting Tools
Several cleaning solutions are available for removing black mold. Choose the one that best suits your needs and preferences, whether commercial products or natural remedies.
- Hydrogen Peroxide: A 3% solution is an affordable and effective spray. Avoid contact with fabrics or carpets, which may cause discoloration.
- White Vinegar: Apply it full strength or dilute it with equal parts warm water for cleaning. Spray white vinegar onto affected areas after cleaning as a preventative measure.
- Baking Soda: Dissolve a teaspoon of baking soda in a cup of water to create a safe, non-toxic cleaner. Combine with white vinegar for added cleaning power.
Avoid using bleach unless the surface is completely non-porous. Bleach cannot penetrate porous materials like wallboard, making mold and mildew removal ineffective in areas beneath sinks.
3. Know Your Limits
While many mold removal tasks are manageable for homeowners, some require professional intervention to protect your health. Consider hiring certified mold remediation specialists if:
- Mold covers a large area (more than 10 square feet).
- The mold source is inaccessible or involves structural damage.
- You or someone in your household has health concerns, such as allergies or respiratory issues.
Preventing Mold In The Future
After removing the mold under your kitchen sink, make sure that you first find out the cause of the mold and eliminate the problem. Moisture under the kitchen sink usually occurs when you have a plumbing leak, so fix the leak to prevent future problems. In some cases, consider replacing the kitchen sink.
You can also purchase a mold inhibitor solution, an additive that can be added to paint or other solutions. Apply a little mold inhibitor under the sink in areas where mold might grow. To reduce mold growth in your home, keep the humidity below 40%.
How To Remove Unpleasant Smell From Sink
If there is no mold damage, and the sink still emits an unpleasant smell, we recommend turning to “grandmother’s” methods:
- Pour 1 cup of salt into a plum, pour 300 ml of boiling water, leave for 3 hours, then turn on hot water and wait 5 minutes;
- Mix salt and soda in equal proportions, pour into a drain, pour boiling water after half an hour;
- Pour one bag of citric acid into the drain and pour 100 ml of hot water.
When To Call A Professional
While DIY mold removal can be effective for small infestations, there are cases where professional help is necessary. If you notice mold growing in hard-to-reach areas, such as behind your cabinets or within your walls, or if the problem has spread extensively, it’s best to call in an expert. Mold remediation companies have specialized equipment to deal with mold effectively and safely, and they can also offer advice on preventing future mold issues.
Verdict
Mold under your sink may sound too big to handle, but with the proper approach and careful execution, it can be tackled successfully. Adhering to these steps can stop the proliferation of mold, address the causative elements, and keep the space under your sink clean and healthy for years.
