Mould Prevention: 4 Ways to Prevent Mould Growth in Your Workplace

27th July 2020

Exposure to mould has been linked to a variety of health effects, including breathing problems and allergic reactions. Mould needs moisture, oxygen, and an organic source such as wood, food, carpet, and paper to grow. It may grow inside your work environment without you even realizing. Preventing its growth is the most effective way to control it and keeping the workplace safe. Read on for some of the most effective ways to prevent mould growth in your workplace.


  1. Keep the Workplace Clean

Maintaining workplace cleanliness is one of the most effective ways to prevent mould growth in your facility. Fungi thrive mostly on soap and films that coat surfaces such as bathrooms, grout, and tiles. Ensure to thoroughly scour tubs and sinks. Clean any wet or damp building materials within 1 to 2 days to prevent mould growth. Garbage pails are also a prime breeding ground for mould and they need to be cleaned frequently.

In most instances, you’ll only need your normal bathroom cleaners and ordinary laundry detergents to clean the areas. You should also wear the proper PPE such as eye protection, gloves, and a mask to protect you from any airborne spores. After every cleaning, ensure to dry surfaces completely. You may need access equipment such as a safety ladder to conveniently and effectively access different parts of your facility.


  1. Keep it Dry

While it may not be possible to eliminate mould inside your workplace, controlling excess moisture can be crucial to stopping indoor mould growth hence reducing the presence of mould in your facility. To achieve this, you can use the following steps:

  • Lower humidity levels in damp areas by raising the temperature. The indoor quality should be below 70%; usually 25-60%.

  • Use exhaust fans in kitchens and washrooms to vent moisture to the outside.

  • Increase indoor air and heat circulation by opening doors, installing fans, and moving furniture away from wall corners.

  • Use a dehumidifier to remove moisture from damp areas.


  1. Use Building Supplies

There are common building supplies that you can use to prevent mould growth in your facility. You can add insulation to floors, roofing and walls and around piping and windows to help reduce condensation. You can also use storm windows to prevent condensation and hence mould growth around windows, especially during cold weather. If you have carpets on your concrete floors, consider inspecting them regularly as they can easily absorb moisture, which encourages the growth of biological pollutants. You may consider using area rugs that can be easily removed for cleaning more often. You may also use a vapour barrier of plastic sheeting over the concrete if you’re operating under damp climates. In case you’ll need to install wall-to-wall carpet, ensure to cover the vapour sheeting with a subflooring of insulation covered with plywood.


  1. Seal the Leaks

Leaks increase the presence of moisture, which provides an ideal environment for mould growth. You need to conduct regular inspection to identify and repair any plumbing leaks, water seepage through walls, poorly vented clothes dryers, or blocked drains. Look for condensation and wet spots around the areas you’re most likely to experience leaks, especially after a change in the weather. You should also use waterproof covers to cover crawl spaces to prevent moisture from coming in from the ground.
