Yes. Mould Assassins treat the mould, address the cause of the mould and provide aftercare recommendations to prevent regrowth.

- Do you offer a warranty?
Yes. We provide a 12-month limited warranty on mould remediation and certain restoration services.
- Can I use vinegar to clean mould?
Yes. However please note that vinegars’ acidity can cause damage to materials and it doesn’t have the killing or cleaning power of dedicated mould products our assassins use. In other words, your mould will be growing back.
- Can I use tea tree oil and eucalyptus oil-based products to clean and treat mould?
Yes. These oil based products can stain your materials and paint. They also leave an oily residue that attracts more dust that creates a surface for the mould to regrow. These products are also toxic to people and animals and if used in incorrect concentrations can be harmful and dangerous to your health. It is particularly toxic to animals! Also, if used in high concentrations or incorrectly applied can leave a very strong smell for days or weeks.
- Can I use bleach to kill mould?
No. Bleach temporarily eliminates the colour of the mould and is not an effective long-term solution or treatment of mould. Bleach can be used on hard or non-porous surfaces but the mould roots normally stays in-tact and will continue to grow and spread pores
- My local hardware store sells a spray on mould killer – does this work?
es. Most of the “spray on” solutions are just a band-aid fix if the mould is not correctly cleaned and treated their effectiveness is limited. It is important to know the root of what causes to mould to ensure effective mould elimination.
- Can mould harm me?
Yes. Mould can cause significant health issues. Our assassins use protective equipment when cleaning mould, this protects the assassin from inhaling the mould or accidentally getting spores into tear ducts (eyes) etc. The protective equipment also protect the assassin from any harmful side effects of any chemicals used.
If in doubt please contact your health practitioner to assess whether you have mould allergy or sensitivity.
- How do I clean mould from carpets?
Cleaning mould from carpets will need a deep carpet clean but using the right chemicals. Drying the carpet after cleaning is very important. Open fabrics and carpets allow mould to travel deep into the fabric which makes it very hard to clean. However once the mould has contaminated the underlay, replacement of the carpets will be necessary.
- Can I clean mould myself?
Yes, absolutely! Using the correct chemicals and cleaning methods can be very successful for light mould contaminations. For moderate to severe contaminations using a trained mould remediation technician is sometimes the only way to fully address the contamination. There may be hidden issues that only specialist equipment can find.
- How do I know if I have a water leak?
More often than not, you will only know that you have a leak once the floor is wet. More significant leaks (like burst water pipes) are far more visible. Smaller leaks (like a slow drip) will result in water stains and visible mould on surfaces before flowing water is seen. A moisture detector and thermal camera is usually the best way to find any water leaks.
- What are the signs of mould?
An odd, musty smell is usually the first sign. Small black dots on surfaces are a likely early sign of black mould contamination. White and grey mould can look like a dust layer on surfaces and are not always easily seen.
- Can I just paint over the mould?
No. A new coat of paint will not stop it. Mould resistant paint helps but if the mould is not killed and cleaned it will simply grow through your new paint again.
