When his word wasn't enough evidence.
A landlord in Aylesbury rented out his mould-free home. A month later, the tenants blamed the building. The lab told a different story.
Survey and dry-fog treatment completed in a single visit
Airborne mould-spore count vs outdoor reference, same day
"Whenever I have the chance to advocate, I will. The treatment is done once — and if the conditions are kept, the problem is solved."
A landlord's defence.
Peter Watkins had lived in the house for three years without mould. Then he rented it out — and within a month, the tenants told him the building was at fault.
He lived in the house for three years. Three winters — not once did mould appear.
Then he rented it out. Within a month of new tenants moving in, mould was spreading across the walls. The tenants blamed the building — the insulation, the structure.
He'd already told the tenants what to do: open every window ten minutes a day, clean mould the moment it appears, stop drying laundry indoors. They didn't. He needed evidence.
"Most of your negative reviews are about customers who paid a lot of money and then had issues. I found those issues were the customer's fault, not yours."
He chose us by reading our negative reviews — 18 years in e-commerce taught him what those reveal. We treated the property in one visit and handed him a Eurofins-verified report that ruled out the building.
Four rooms sat at or below the dew point on arrival — every room logged condensation as the moisture source.
Furniture pressed flush against cold external walls trapped moist air across bedrooms, lounge and kitchen — classic dead-air interaction.
Kitchen sink loose with failed silicone, driving moisture into the cabinet below — and heavy concealed mould behind a built-in bathroom cabinet.
After a single day of treatment, indoor airborne mould-spore counts were measured 5× lower than the outdoor reference sample — a 99.998% reduction, from 3,900,000 to 93 per cubic metre. Eurofins (AIHA-accredited).
"I check every page. Most of the time, the negative reviews indicate whether a company has a problem."
The process behind transformation.
Four stages. One day on site. Independent lab evidence at both ends — before you spend, and after we leave.
Comprehensive survey and independent laboratory testing to identify the root cause — not just the visible symptoms.
Patented two-step dry-fog process, applied throughout the property to reach every surface the air touches and reduce mould contamination, then an antimicrobial film to inhibit regrowth.
Post-treatment lab testing gives written, independent evidence of the spore-count reduction. No claims without numbers.
A follow-up in the weeks after treatment confirms the result has held — clear air, no regrowth, and the evidence to prove it.
What a homeowner actually wants to know.
Yes. Pre-treatment readings, outdoor baselines and a documented inspection give you evidence for any dispute. Peter's report ruled out the building.
Dry fog reaches every surface the air touches. Indoor air went from 3.9m to 93 spores per m³ in a day — oxidised and denatured down to outdoor-equivalent levels.
One working day. Peter's three-bed terrace was surveyed, dry-fogged and lab-sampled on 20 January. The tenants vacated for the day and returned that evening.
The 12-month warranty applies where post-treatment conditions are followed. If conditions slip, we re-treat at no extra charge — Peter's property is being re-treated before the next tenancy.
If you think you have a problem with mould, start with a survey.
Diagnostic moisture & mould survey. Independent US-tested treatment. Lab-verified results. 12-month limited retreatment warranty (T&Cs apply).
A diagnostic visit to identify exactly what's happening — before you spend anything on treatment.
Subject to availability and survey findings, urgent cases may be booked within 24 hours — most homes treated in a single day.
