Commercial Mould Remediation & Investigation

Supporting letting agents, property managers and housing providers across the South East

We understand what’s at stake.

Managing properties today isn’t just about maintenance, it’s about responsibility.

With increasing expectations around tenant safety, documentation and compliance, mould is no longer something that can be dealt with reactively or superficially.

It needs to be:

  • Properly investigated

  • Professionally treated

  • Clearly documented

That’s where we come in.

Our approach: investigation first, always.

At ClearCo, we don’t just treat what you can see.

We focus on understanding why it’s there in the first place, because mould is a symptom, not the cause.

Every job includes:

  • A full visual inspection

  • Moisture readings of affected materials

  • Humidity, temperature and dew point analysis

  • Identification of contributing factors (ventilation, heating patterns, building defects)

This allows us to give you clear, evidence-based recommendations, not guesswork.

Professional remediation, done properly.

We follow a structured remediation process aligned with IICRC S520 principles, ensuring mould is dealt with safely, thoroughly and in a controlled manner.

Depending on the level of contamination, our approach may include:

  • HEPA vacuuming to reduce airborne spores

  • Physical removal and cleaning of affected materials where required

  • Targeted application of professional treatments to remaining surfaces

  • Detailed clean-down to remove residues and leave areas safe and ready for redecoration

This is not a wipe-down or paint-over approach.


It’s a considered process focused on proper removal, control and prevention, reducing the likelihood of recurrence when paired with the right corrective actions.

Supporting proactive property management.

We work with clients not just reactively, but proactively across their portfolios.

This can include:

  • Pre-tenancy or routine moisture checks

  • Early-stage risk identification before mould develops

  • Ongoing support and advice for recurring problem properties

The goal is simple: fewer repeat issues, fewer complaints, and better control across your properties.

Who we work with

We regularly support:

  • Letting agents

  • Property managers

  • Housing associations

  • Landlords with multiple properties

Whether it’s a single property or multiple sites, we aim to be a reliable, professional extension of your team.

Accreditations & compliance.

We understand the importance of working with trusted contractors.

ClearCo is:

  • Fully insured (Public Liability & Professional Indemnity)

  • SafeContractor approved

  • COSHH compliant for all chemicals used

  • Registered waste carrier (where applicable)

All works are carried out in line with current health and safety standards, with RAMS available where required.

Let’s have a conversation.

If you’re dealing with ongoing mould issues, or looking to take a more proactive approach across your properties, we’re always happy to help.

Whether it’s a single case or a wider portfolio, we can talk through the best way forward.
