Did you know that mould requires only a minimal amount of moisture to grow and can start colonizing in as little as a day? It can adapt to a wide range of temperatures and grow on inorganic surfaces such as glass, tile, or steel, though it needs to feed off organic sources such as drywall, fabric, insulation, wood, or stucco. Mould can spread easily through ventilation systems and produces mycotoxins — poisonous, airborne substances that you, your employees, and customers can breathe in.
Simply put, mould can be a hazard to your commercial property and overall business. Thankfully, it can be identified, removed, and prevented. Here’s how:
How to identify mould
When looking for mould in your property, here are some common mould growth symptoms that you should look out for:
- Stained ceiling tiles or walls
- Musty, earthy, or urine-type odors
- Black, brown, orange, pink, or green speckles around plumbing, grout, or tile
There are many different reasons why mould may begin to grow in your building, but some of the most common causes of mould include:
- A leaky roof
- Damages from a flood or hurricane
- Plumbing leaks at drains and gaskets
- Lack of ventilation in your building
- Faulty air conditioning, ventilation, or heating systems
- Cracked or disconnected kitchen appliance hoses
How to prevent mould
Once you have mould in your building, it is extremely difficult and expensive to eradicate. Here are some steps you can take in order to help prevent mould growth:
- Make sure that your business property’s humidity level is always below 50 per cent
- Use an air conditioner or dehumidifier as needed
- Ensure that you ventilate properly with exhaust fans in kitchens (if applicable) and bathrooms
- Add mould inhibitors to any paints before application
- Clean any bathrooms using mould killing products
- Use air purifiers if necessary
- Remove any carpets from bathrooms and basements
- Repair any leaky roofs, walls, and basements
- Remember to clean, disinfect, and dry everything after a sewer back-up or flooding
What to do if you have mould
Cleaning mould involves identifying and removing the sources of excess moisture, then using the simplest cleaning method to effectively remove mould growth.
Small areas — Less than one square meter or 10 square feet of visible mould contamination
A healthy person can clean small areas by bagging and disposing of material with visible mould growth while wearing an approved N95 disposable respirator, gloves, and eye protection. As these materials are removed, check exposed areas for mould growth and clean as needed. Less-porous material like glass, plastic, concrete, or metal can be thoroughly cleaned using a strong detergent followed by lots of water.
Moderate areas — One to three square meters or 10 to 30 square feet of visible mould contamination
Clean these areas using the procedures above but make sure to contain the mould damaged areas with well-sealed plastic barriers and the regular use of a HEPA (High Efficiency Particulate Air) vacuum.
Large areas — More than three square meters or 30-plus square feet of visible mould contamination
These require the expertise of a professional mould clean-up contractor.
