Specialist Mould Treatment Services
Scientifically-proven solutions that eliminate mould at its source
Say goodbye to recurring mould problems. Our advanced biological treatment delivers long-lasting results where conventional methods repeatedly fail.
Not All Mould Treatments Are Created Equal
Most “treatments” you’ll find are glorified bleach solutions. They mask the problem temporarily, but leave the microscopic roots intact beneath the surface. That’s why the mould returns within weeks—sometimes even appearing darker than before.
Three summers ago, I was called to a magnificent Edwardian home in Blackheath where the owners had tried five different retail products to treat their conservatory mould. Each time, the mould vanished briefly, only to return more aggressively. The issue? Those products were killing the surface mould but inadvertently feeding the underlying fungal network. It’s like pruning a weed without removing the roots.
Our approach is fundamentally different. We don’t just kill visible mould—we introduce specialised microorganisms that consume the entire mould structure, including the invisible network extending deep into walls and timber.

Our Biological Mould Treatment Process
We’ve refined our treatment protocol through thousands of successful applications across London’s diverse property types.
Microbiological Application
We apply our proprietary biologically-active enzyme formulation that digests mould structures.
This isn’t some fancy marketing term—it’s genuinely fascinating science. Our enzyme solution contains non-pathogenic microorganisms specifically cultivated to consume mould as their food source. These microscopic organisms penetrate porous materials to depths of up to 8mm, breaking down mould hyphae (the “roots”) that other treatments simply can’t reach.
I remember testing an early version of this formula in my own bathroom about seven years ago… with disastrous results that temporarily turned my ceiling an alarming shade of purple! Thankfully, we’ve perfected the formula since then. The current generation leaves no residue and works silently at the microscopic level to eliminate mould completely.
Fungicidal Treatment
After the biological phase, we apply a professional-grade fungicidal solution that eliminates remaining spores.
Our secondary application contains a polymer-bonded fungicide that provides immediate protection against airborne spores while the biological treatment continues working. This dual-action approach ensures both immediate and long-term protection.
The particular fungicide we use took me nearly a year to source properly. Most commercial options were either too toxic for residential use or too weak to be effective. This one sits in that perfect middle ground—powerful against mould but remarkably gentle on your household. It’s the same medical-grade formula used in several London hospitals to protect immunocompromised patients.
Protective Barrier Application
We finish with a microporous protective coating that allows surfaces to breathe while preventing future mould establishment.
This final layer is what truly sets our treatment apart. Unlike standard anti-mould paints that simply contain a fungicide, our protective barrier incorporates silver ion technology with a microscopically porous structure. This allows moisture to escape (preventing condensation) while maintaining an actively hostile surface for mould spores.
For bathroom applications, we also replace silicone seals with a professional-grade anti-fungal alternative. It costs about three times more than standard silicone, but it’s worth every penny in lasting protection. The difference became strikingly clear when treating side-by-side apartments in a Docklands development last autumn—the unit where we’d replaced silicone remained mould-free, while the one where the client declined this service showed mould returning around the shower within months.
Tailored Treatment Solutions for Different Mould Types
Black Mould Treatment
Stachybotrys chartarum (black mould) requires specialized handling due to its potential health implications and resistance to standard treatments.
Our enhanced protocol includes HEPA filtration during treatment and a more concentrated enzyme application phase to ensure complete elimination.
White/Grey Mould Treatment
Often found on organic materials like wood and fabric, these moulds (typically Cladosporium or Aspergillus species) can cause significant material degradation.
We combine our standard treatment with specific wood-preserving compounds when necessary, ensuring both the mould and its food source are addressed.
Dry Rot Treatment
Serpula lacrymans (dry rot) is particularly destructive to timber structures and requires an aggressive treatment approach to prevent structural damage.
Our specialist dry rot protocol includes targeted biological treatment of affected timber plus preventive application to adjacent materials to prevent spread.
Hidden Mould Treatment
Mould growing inside walls, behind tiles, or under flooring presents unique challenges for effective treatment without major demolition.
Our non-invasive injection system delivers treatment compounds directly into cavity spaces, eliminating hidden mould without unnecessary construction work.
Why Proper Mould Treatment Matters for Your Health
The health impacts of living with mould extend far beyond the occasional sneeze or cough. Ongoing exposure to mould spores can trigger serious respiratory conditions and exacerbate existing health problems.
Professional Treatment Helps Alleviate:
- Persistent respiratory infections and bronchitis
- Allergic reactions including skin rashes and eye irritation
- Sleep disturbances from nighttime coughing
- Headaches and concentration difficulties
- Asthma attacks and breathing difficulties
Most concerning is how gradually these symptoms develop—many people don’t connect their chronic health issues to the mould lurking in their homes until the problem becomes severe.
Last winter, we treated a Victorian flat in Pimlico where a young couple had been experiencing persistent “colds” for nearly a year. The wife, a professional singer, had nearly abandoned her career due to constantly strained vocal cords. Their GP had prescribed everything from antibiotics to inhalers with minimal improvement.
The culprit? A hidden mould infestation behind their bedroom wardrobe that had developed after a small roof leak. Within three weeks of our treatment, both reported sleeping better and breathing easier. Six months later, she was performing again. I’m not claiming our treatment cured them—I’m not a doctor—but removing a significant source of respiratory irritation clearly allowed their bodies to recover.
How Our Treatment Compares to Alternatives
Understanding the differences between treatment options helps explain why some solutions fail while others succeed.

Nearly identical mould problems can require vastly different treatments. During a recent project in Chiswick, what initially appeared to be simple bathroom mould turned out to be connected to a much larger hidden issue within the wall cavity. This is precisely why we never quote sight unseen—you deserve an accurate assessment, not a one-size-fits-all estimate.
What Our Treatment Clients Say
“After trying everything from bleach to expensive ‘mould killers,’ I was skeptical about any treatment working in my Victorian flat. The specialist explained their biological approach, which seemed almost too scientific to be true. But it’s been 14 months now and not a speck of mould has returned. Worth every penny.”
— Daniel R., Islington
“My daughter’s asthma was getting worse despite numerous GP visits. The treatment team found black mould behind her wardrobe that regular cleaning couldn’t reach. Since their treatment four months ago, her symptoms have improved dramatically. The technician even called to follow up about her health a month later, which I found incredibly thoughtful.”
— Lakshmi P., Tooting
“We had serious mould issues in our basement conversion that two previous ‘treatments’ from other companies hadn’t solved. The biological approach these specialists used was completely different. The only reason for 4.5 stars instead of 5 is that the treatment has a distinct smell for the first couple of days, but it does fade completely. The results have been excellent with no return of mould in 9 months.”
— Thomas W., Richmond
Frequently Asked Questions About Our Mould Treatment
How is your biological treatment different from regular anti-mould treatments?
Standard treatments typically use fungicides or bleach to kill surface mould, but they can’t penetrate deep into porous materials where mould roots (hyphae) hide. Our biological treatment uses specialized microorganisms that actively consume mould structures, penetrating up to 8mm into materials. These microorganisms continue working for weeks after application, breaking down the entire mould network, not just visible surface growth. We follow this with professional-grade fungicides and protective coatings to provide immediate and long-term protection.
Is your treatment safe for homes with children, pets, or people with allergies?
Yes, our treatment is specifically formulated to be safe for sensitive environments. The biological component uses non-pathogenic microorganisms that are harmless to humans and pets. The fungicidal phase uses medical-grade compounds similar to those used in healthcare settings. We recommend staying out of treated rooms during application and for 3-4 hours afterward to allow surfaces to dry. People with severe chemical sensitivities should inform us beforehand, as we can modify our protocol with even gentler formulations if necessary.
How long does your mould treatment last?
Our treatments typically provide 3-5 years of protection under normal conditions. This varies depending on environmental factors such as ventilation, humidity levels, and whether underlying moisture issues are addressed. Our 6-month guarantee means we’ll return at no cost if mould reappears during that period, but honestly, we rarely need to. In particularly challenging environments like poorly ventilated basements, we recommend supplementary preventive measures like improved ventilation or dehumidification to maximize treatment longevity.
Will the treatment damage or discolor my walls, ceiling, or other surfaces?
Our treatment is designed to be non-damaging to most household surfaces. The biological component is colorless and won’t affect paints, wallpaper, or most materials. The protective coating is clear or white depending on the application area. For aesthetically sensitive areas like period features or decorative finishes, we conduct a small test patch first. Severely affected porous materials that have been damaged by long-term mould growth may occasionally need replacement rather than treatment, but we’ll discuss this during the assessment if applicable.
Can I stay in my home during the treatment?
Yes, you can remain in the property during treatment, though we recommend staying out of the specific rooms being treated. The process doesn’t require evacuation as some more invasive treatments do. There’s a mild odor during application that dissipates within a few hours. We typically suggest keeping doors to treated rooms closed with windows slightly open for 3-4 hours after completion. For whole-house treatments, we can work room by room to minimize disruption to your daily routine.
Do you treat commercial properties?
Absolutely. We provide specialized mould treatment solutions for commercial spaces including offices, healthcare facilities, schools, restaurants, and retail properties. Commercial treatments often require customized approaches to accommodate business hours and minimize disruption. We can work evenings and weekends if needed. Our commercial clients particularly appreciate our biological approach, as it doesn’t release harsh chemical odors that could disturb staff or customers. Please contact us directly to discuss your commercial requirements.
