What to Do if Mould Keeps Coming Back?

At I-sells  we recognise the discomfort, destruction and danger that can be caused by inadequate ventilation, along with environments that are not properly maintained, and that can become susceptible to mould.

Mould can and will spread if left unattended, but it can be dealt with in a variety of ways, in this blog, we will be discussing “‘What to do if mould keeps coming back?”

Mould is known for its resilience, however, this is to our detriment, as mould can be a precursor or an agitator of many health issues including respiratory problems. This resilience makes it hard to combat, but sometimes the cause of mould may just be more than a surface issue.

What causes mould?

Mould in your home generally occurs as a result of condensation.

Condensation occurs when heat and moisture in the air are confined to a certain area, as this heat tries and fails to escape, droplets of water are created on cold surfaces. A good way to think about this is having a hot shower on a cold day and not opening your window.

The reason condensation creates mould is that a damp and humid environment is the optimum condition for mould to grow. In regards to windows, it is a big problem if there is mould on your windows (it can usually be found in the corners of the windowpane or the walls connected to the window).

The true danger of mould is that its particles can travel through the air without us seeing it, incidentally, this means opening a window with mould on it runs the risk of that mould being blown inside your room alongside the fresh air.

That being said, condensation is not the only cause of mould, it can occur from leaks in the structure of a building too. Aside from this, mould can develop from out-of-date food, which spreads to other food that is left near it.

Mould treatment options

When it comes to treatment for mould, you can’t expect it to be removed by itself, so here are some options when it comes to treating them with household items, or specially designed mould treatment products.

Using Vinegar to treat bleach

What you will need:

  • White vinegar
  • An Empty spray bottle x2
  • Baking Soda
  • Scrub pad or brush
  • Mask, gloves, goggles.
  1. Apply your safety equipment before commencing
  2. Pour the vinegar into the empty spray bottle, then use the spray bottle on the moulded area, be sure to spray directly onto the mould. After spraying, leave it for an hour minimum.
  3. Add a teaspoon of baking soda and two cups of water in your spare spray bottle, and shake thoroughly. This is your baking soda scrub.
  4. Spray the scrub directly onto the mould just as you did with the vinegar, then scrub the area, the baking soda helps to remove any stains caused by the mould. Rinse the area with warm water after the scrub.
  5. Spray the area once more with your vinegar or baking soda solution, (either is fine) then leave the area to air-dry.
