Professional Mould Removal That Protects Your Home and Health!
Expert mould remediation solutions designed to identify, test, and tackle visible and hidden mould issues in your property.
Identify black spots, staining, damp patches, and the source of moisture fast.
Mould Removal
Our Visual Mould Survey focuses on identifying visible mould growth in your property. Using thermal imaging, moisture meters, and air quality checks, we pinpoint the source of moisture and assess the full extent of the problem.
Every visual survey includes a detailed written report with photographs, findings, and practical recommendations for safe remediation and long-term prevention.
qPCR Hidden Mould Test
For mould that you can’t 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.
Each test includes a laboratory report with clear guidance on next steps.
Advanced testing for mould you can’t see but may be affecting your air quality.
Track humidity, temperature, and condensation patterns to prevent mould at its source.
Environmental Monitoring
Our Environmental Monitoring service provides detailed insight into the conditions inside your property that can lead to mould growth. Following a professional survey, we install specialist data loggers to track humidity and temperature patterns over time.
This helps identify issues like poor ventilation, heating patterns, condensation risk, and indoor humidity behaviour that may not be visible during a single visit.
You’ll receive a clear report with graphs, analysis, and practical recommendations to control moisture and prevent mould returning.
UV-Activated Protective Coating
As part of our remediation works, we can apply a light-activated antimicrobial coating to provide an additional layer of surface protection.
This specialist coating becomes active when exposed to natural or artificial light and helps support cleaner surface conditions over time.
It is ideal for walls, ceilings, bedrooms, bathrooms, living areas, and spaces where stable environmental conditions are harder to maintain.
Additional surface protection to support longer-term results after remediation.

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 wife’s cleaning services as they were carried out to the highest standard. We will definitely use his other services regarding cleaning again.

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.

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.
