Ultimate Guide to Preventing & Removing Mould

Nobody wants to live in a mould-invested home. Unfortunately, mould can grow almost anywhere, from ceilings to furniture – this can cause health problems for your tenants, can create costly maintenance issues, and lower the rent value and demand for your Wellington rental property.


How To Prevent Mould

  • Install extraction fans in the kitchen and bathroom.

  • Install a positive pressure system such as DVS or HRV.

  • Install security stays on lower level windows to allow the tenants to safety ventilate.

  • Include a dehumidifier to enable tenants to remove moisture from the property.

  • Repair water leaks in the roof, windows, or any other part of the home as soon as you become aware of them.

  • Check refrigerator and fridge doors seal properly to prevent moisture escaping.

  • Install insulation in the ceiling, walls and underfloor.


How To Remove Mould From Surfaces


Use Laundry Detergent To Remove Mould

  1. Wipe or scrub surface with a mixture of water and either laundry detergent or dishwashing soap.

  2. Rinse area and dry quickly with a towel.

Use Chlorine Bleach To Kill Mould

  1. Scrub surface with water and detergent.

  2. Water down chlorine bleach (approx. 1:10 ratio).

  3. Spray the mouldy area with the diluted chlorine bleach and leave for approximately 15 minutes to kill the mould.

  4. Rinse area and dry quickly.

A Note Of Caution

  • Keep chlorine bleach out of reach from children.

  • Be careful not to splash or spill chlorine bleach on fabric or rugs as this can remove their colours.

  • Never mix chlorine bleach with products containing ammonia or acids – this will create a deadly gas.

Want A Bleach-Free Alternative?

A bleach-free alternative is Wet & Forget Mould and Sanitising Cleaner. This formula doesn’t release harsh fumes and is easy to use, allowing mould to be effectively killed and inhibit re-growth, making this a good option for many Wellington rental properties.
