How to Reduce Mould in your Home


Moulds are microscopic fungi that tend to grow in the form of multicellular filaments called hyphae. Mould mostly thrives in organic matter, including ceilings and floors of homes with moisture problem management. Mould can grow just anywhere, but mould is mostly found in bathrooms, kitchens, basements, and near pipes. The most common mould problem is mould behind drywall. Ceiling mould is also common due to lack of ventilation and moisture accumulation. Keep reading to find out how to reduce mould in your home.

Causes of Moulds in Our Homes

  1. Leaking Pipes in Homes
    This is one of the common causes of mould since mould requires moisture to thrive. Leaking pipes mainly contribute to ceiling and wall mould.
  2. Leaking Roofs
    Roofs partially damaged due to wear and tear or adverse weather conditions may quickly build up mould in homes.
  3. Persistent Humidity
    In areas where humidity is consistently high, one is likely to have problems with mould. This is natural due to the high moisture content in the air. Mould caused by humidity is common in areas near water bodies.
  4. Poor Home Ventilation
    This is a magnet for mould growth and spreading mould spores. The steam created by home appliances causes humidity in homes, leading to damp and sticky surfaces.
  5. Wet Clothing
    Clothes that are wet can contribute to existing mould problems. Mould only needs twenty-four hours to grow.
  6. Home Flooding
    When home floods, it may take days or even weeks before the home is completely dried out, which is an ideal environment for mould to grow. The worst part about a flooded home is that it can lead to the growth of a very toxic mould known as Stachybotrys chartarum.
  7. A Damp Basement
    It’s natural that basements are exposed to higher levels of moisture, which is ideal for mould growth.

How To Control Mould

Identifying Problem Areas in your Home and Correct Them

  1. It is very difficult to mould-proof your home, but one can make sure that the home has become mould resistant. Start with an audit in your home and discover the areas that have been greatly affected by mould. Preventing mould from growing and spreading is simple as you may install mould-resistant products or repair damaged gutters. Whatever the problem is causing mould, you are supposed to address the problem immediately. Addressing a problem might cost some money upfront, but it will surely be costlier if one lets the mould continue growing unchecked.

  2. Dry Wet Areas Immediately
    Mould can’t grow without water, so it is advisable to tackle wet areas immediately. After a heavy downpour, accumulation from leaky pipes, and even spills on carpets, water in the basement should be dried within 24-48 hours. For instance, if you have a flood in your home, you should remove water-damaged carpets, bedding, and furniture if they are soaked. Everyday occurrences within the house also need attention. Don’t leave damp clothes lying around the house or in the washing machine, and after a shower, be careful to dry the floor and walls.

  3. Prevent Moisture with Proper Ventilation
    Your everyday household activities may promote mould growth in your home. By ensuring sufficient ventilation in your bathroom, kitchen, laundry room, and any other high-moisture location, there will not be the growth of any mould. Vent moisture-producing equipment outdoors, such as laundry dryers and stoves (not the attic). Use air conditioners and dehumidifiers (particularly in humid locations), but check them occasionally and clean them according to the manufacturer’s instructions to ensure they don’t create moisture. If you’re cooking, washing dishes, or bathing in your energy-efficient house, open a window or use an exhaust fan to let the moisture out.

  4. Equip your home with Mold-Resistant Products
    Use mould-resistant drywall or Sheetrock, as well as paints with mould inhibitors. A gypsum plaster core is sandwiched between plies of paper in traditional drywall. The gypsum core is coated with fibreglass, making the surface very water-resistant. Bathrooms, laundry rooms, basements, and kitchens benefit from moisture-resistant drywall. Traditional drywall is not only more prone to mould than paperless drywall, but it is also more difficult to remove and replace. Mould-resistant gypsum board is also available and the drywall’s core is designed to keep moisture out and prevent mould development.

  5. Monitoring Humidity Indoors
    According to the Environmental Protection Agency, indoor humidity should be between 30 and 60 per cent. A moisture meter, available at your local hardware shop, may be used to determine humidity. By just paying attention to possible issue spots in your house, you’ll be able to detect high humidity. Condensation on windows, pipes, and walls are all telltale symptoms of too much humidity. If you see condensation on a surface, dry it right away and determine what’s causing it (for example, turn off a humidifier if water appears inside nearby windows).

  6. Directing Water Away from your Home
    Water may gather around your home’s foundation if the earth around it isn’t appropriately sloped away from it, allowing it to seep into your crawlspace or basement.

  7. Cleaning and Repairing Roof Gutters
    A roof leaking due to full or faulty gutters might be the source of a mould problem. Clean and examine your roof gutters regularly. After storms, look for water stains that might indicate a leak and repair them as needed.

  8. Improving Air Flow in Your Home
    According to the Environmental Protection Agency, when temperatures drop, the air’s ability to hold moisture decreases. Open doors between rooms, move furniture away from walls, and open doors to closets that may be cooler than their rooms to improve circulation. Allow fresh air to circulate to minimize moisture and prevent mould growth.
