Mould Remediation
Professional mould remediation, done the right way.
Mould isn’t just something to clean, it’s something to understand.
On this page we explain, in more detail, how we investigate mould problems, the readings we take, and exactly how our four-stage mould treatment works.
If you want the reassurance and the “why”, this is where you’ll find it.
Why investigation matters.
Mould is a symptom, not the cause.
Mould forms when moisture levels allow it to grow. That moisture might come from condensation, poor ventilation, leaks, or cold surfaces, and without identifying the source, treatment alone won’t last.
That’s why every mould remediation job we carry out starts with a proper investigation, not just surface cleaning.
Our mould investigation process
Before any treatment begins, we carry out a structured investigation to understand what’s happening within the property.
We don’t rely on assumptions. We gather evidence.
This includes:
Visual inspection
Identifying affected areas, patterns of growth, and signs of condensation or ingress.Photographic records
Clear visuals to document conditions and support our findings.Moisture readings
Taken within walls, ceilings and building materials to identify excess moisture.Humidity readings
To understand how much moisture is present in the air.Temperature readings
Cold surfaces combined with warm air are a common trigger for condensation.Dew point analysis
This helps us identify where and when condensation is likely to form.
Together, these readings allow us to understand why mould has appeared, not just where.
Our four-stage mould treatment process
Once the cause has been identified, we carry out mould remediation using a structured four-stage process. Each stage plays a specific role in removing mould safely and thoroughly.
Stage 1 – HEPA vacuum extraction.
We begin by mechanically removing loose mould spores and contaminated particulates using a commercial HEPA-filtered vacuum system.
HEPA filtration captures microscopic spores that standard vacuums would simply redistribute into the air. This step reduces airborne contamination, prevents cross-spread during treatment, and prepares the surface for effective chemical application.
Stage 2 – Primary antimicrobial treatment (surface neutralisation).
We apply a professional-grade antimicrobial solution designed to neutralise active mould growth on the surface.
This treatment kills visible mould colonies and begins breaking down biological contamination across the affected area. Proper dwell time is observed to ensure the product fully penetrates the surface layer and achieves maximum effectiveness.
Stage 3 – Secondary treatment (deep penetration root treatment).
Mould growth rarely exists only on the surface. Microscopic hyphae (root-like structures) can extend into porous materials.
The second-stage treatment is formulated to penetrate beneath the surface and target embedded spores and root structures. This significantly reduces the likelihood of rapid regrowth once environmental conditions are stabilised.
Stage 4 – Manual decontamination and wash-down.
All treated areas are then manually cleaned and washed down to remove residue, dead spores, and remaining surface contamination.
This final stage ensures the area is hygienically clean, safe to occupy, and properly prepared for redecoration or preventative coatings if required.
This is not a cosmetic wipe-over. It is a structured, professional remediation process designed to remove contamination at both surface and sub-surface level.
Reporting & recommendations.
Clear documentation you can rely on.
After the visit, you’ll receive a fully written report detailing:

Frequently Asked Questions
-
Professional mould remediation goes beyond surface cleaning. It includes identifying the affected materials, safely treating and removing active mould, controlling spores during the process, and assessing the moisture source that allowed the mould to develop in the first place.
-
Yes. Standard mould cleaning typically removes visible staining only. Mould remediation focuses on killing active mould growth, reducing airborne spores, and addressing contributing factors such as condensation, humidity or damp materials to help prevent recurrence.
-
Yes. Black mould (Stachybotrys chartarum) is commonly found during mould remediation works. It requires careful handling and professional treatment to ensure it’s dealt with safely and effectively.
-
Mould remediation significantly reduces the likelihood of mould returning when the underlying moisture issue is addressed. If contributing factors such as poor ventilation, high humidity or water ingress remain, mould can reappear over time.
-
Yes. We regularly carry out mould remediation in rental properties and managed buildings. Our service includes clear documentation, moisture readings and practical recommendations, supporting landlords, letting agents and property managers.
-
In most cases, mould remediation can be completed while the property remains occupied. We’ll always advise if any temporary precautions are needed based on the scale and location of the work.
-
Timescales vary depending on the extent of the mould and the materials affected. Smaller areas may be treated in an hour or two, however, if it’s a larger project you might be looking at a full day.
-
We provide professional mould remediation across Kent and the wider South East of England, including London, Essex, Surrey and Sussex.
