qPCR Hidden Mould Test
For mould that you canโt see but may suspect, we provide advanced qPCR testing. This DNA-based test detects hidden mould contamination in walls, floors, ceilings, or the air, even when there are no visible signs. The results identify the exact mould species present, helping confirm whether mould is a hidden cause of odours, allergies, or poor indoor air quality.
Each qPCR test comes with a laboratory report and clear advice on the next steps.

Frequently asked questions

Is Mould Removal Safe?
Yes, professional mould removal is conducted using industry-approved methods that are safe for your property and the people in it. We take precautions to contain the mould during removal and use non-toxic, safe cleaning agents.
How long will Mould Removal Take?

For individuals with asthma, weakened immune systems, or respiratory conditions, mould can worsen symptoms or trigger severe allergic reactions. Children and elderly people are also more vulnerable to the effects of mould exposure.

Sebastian was fantastic. Turned up on time, explained step by step what he would do throughout the process. Provided a detailed report and recommendations on how we could solve our mould issue. Sebastian cleaned and sanitised our house and the effected mould areas. He also provided recommendations of trades people who could assist us with the recommendations. We would highly recommend Sebastian and his wifeโs cleaning services as they were carried out to the highest standard. We will definitely use his other services regarding cleaning again.
Happy Customers, Happy Homes
I can highly recommend Sebastian. Once I contacted his company he promptly returned my call. He offered solutions to my problems with mould in a car. He is very knowledgable about mould treatments and also explained his process for removal very clearly. When he arrived to treat the problem, he was so helpful and courteous. I am so pleased to have found this company and to have found someone to help with this problem. Thank you Sebastian.
Happy Customers, Happy Homes
Sebastian quite literally saved my life. I was faced, unexpectedly, with a severe amount of mould on my kitchen walls when installing a new kitchen. Myself and my young daughter had become ill for sinister unknown reasons. Seb turned up like a SUPERHERO with his gas canister of biocide mould-killing chemicals, and within hours had transformed my home into a sparkling clean, mould-free, disinfected environment. He was friendly and professional at all times and went above and beyond with his advice. Highly recommend this service, it is worth every penny.
