The most effective way to prevent symptoms of mold exposure is by preventing mold in your property. Mold is the symptom of some water issue, so you should check regularly for water leaks. Even a small amount of water can lead to mold. Basements, kitchens, and bathrooms are the most likely to have mold problems, but mold can grow in any area where moisture is present.

The majority of your plumbing runs through your basement, which can lead to plenty of plumbing issues. Inspect your plumbing systems regularly. in finished basements, look for water stains or other signs of water damage. Repair or replace plumbing and HVAC equipment as necessary.

Preventing Kitchen Mold

Mold is common in the kitchen due to both the number of plumbing fixtures as well as condensation and humidity from cooking. Use an exhaust fan whenever possible or open a window when cooking. Check your plumbing regularly, including behind your refrigerator and underneath your dishwasher. Prevent mold by cleaning regularly with a solution of bleach and water.

Preventing Bathroom Mold

Like kitchens, bathrooms are prone to mold due to the plumbing systems and humidity from your shower. Vent your bathroom with an exhaust fan or open a window when bathing. Inspect your shower curtain, caulking, tile grout, and your pipes regularly for signs of mold or water leaks. Wash your bathroom with a bleach and water solution weekly to prevent mold from developing.

A Note About Using Bleach

Mold is a symptom of some persistent source of water. While bleach does kill mold, it will return as long as the moisture remains. For that reason, cleaning with bleach is an effective measure to safeguard against a mold issue. However, bleach is not effective at removing mold permanently.

The Mold Remediation Process

If you have symptoms of mold exposure or see mold, you should have your property inspected by a mold removal and remediation company.

  • Identify and repair the source of moisture that resulted in mold.
  • Contain the contaminated area. Close doors or windows between the mold-contaminated space and the rest of the building. Taping thick plastic sheeting over doorways.
  • Misting the treatment area will help stop dust from spreading mold spores.
  • Dispose of all porous materials that are wet, even if they are not obviously mold-infected. Seal them in heavy duty plastic bags to prevent contaminating other areas during disposal.
  • Thoroughly clean non-porous surfaces with a strong detergent solution then rinsed with clean water.
  • Dry affected areas using standing fans or commercial air movers.
  • Inspect the area for visible contamination, dirt, dust, and debris.
