After an asbestos concern

Why asbestos decontamination needs evidence-led planning

After a suspected disturbance, the priority is to prevent further access, assess the material and establish whether controlled cleaning, air testing or a wider remedial programme is required. The appropriate first step is usually an immediate assessment and controlled decontamination plan.

Before work

Check asbestos risk before materials are disturbed.

Material + condition

Both determine whether removal, encapsulation or management is appropriate.

Complete records

Survey evidence and disposal documentation support safe decisions.

Core body

The three decisions behind a controlled asbestos decontamination programme

Identify the material

Confirm the asbestos risk relevant to areas following suspected asbestos disturbance, damage or uncontrolled work.

Assess condition and access

Damage, weathering, occupant access and planned disturbance determine the appropriate controls.

Plan controlled work

The plan should define the work scope, protective controls, waste route and documentation for asbestos decontamination.

Decision stage

When to act

Before work begins

Arrange evidence before contractors alter the building fabric.

When material is damaged

Restrict access and obtain a competent assessment before cleaning or repair.

Before buying or leasing

Understand asbestos risk before committing to a property or works budget.

When records are absent

A current survey or inspection provides a defensible basis for decisions.

Before disposal

Asbestos waste needs a legal route, appropriate packaging and complete records.

After an incident

Do not disturb suspect debris; arrange an assessment and controlled response.

Understanding the Requirement

Why Asbestos Decontamination Is a Legal Requirement

Under the Control of Asbestos Regulations 2012 (CAR 2012), any area where licensed asbestos removal has taken place must be thoroughly decontaminated before it can be re-occupied. This is not optional — it is a statutory requirement, and the area must pass a UKAS-accredited 4-stage clearance air test before the enclosure can be dismantled.

Decontamination is also required following accidental disturbance of asbestos-containing materials — for example, when a contractor drills through an asbestos ceiling tile or a roofer breaks an asbestos cement sheet. In these situations, prompt professional decontamination is essential to protect the health of building occupants and to comply with the duty of care under the Health and Safety at Work Act 1974.

Environmental cleaning may also be required in buildings where asbestos-containing materials have deteriorated over time — particularly in loft spaces, roof voids, and plant rooms — where fibres may have settled on surfaces over many years. Our asbestos management survey can identify areas requiring environmental cleaning as part of a broader asbestos management programme.

Critical Safety Warning

Never attempt to clean up after asbestos disturbance using a domestic vacuum cleaner. Standard vacuums do not have HEPA filtration and will exhaust asbestos fibres back into the air, dramatically increasing fibre concentrations and the risk of inhalation. Only H-class HEPA-filtered equipment should be used.

Our Services

Decontamination Services We Provide

Post-Removal Decontamination

Following licensed asbestos removal, all surfaces within the enclosure are HEPA-vacuumed and wet-wiped before the 4-stage clearance air test. This is a mandatory step before re-occupation under the Control of Asbestos Regulations 2012.

Accidental Disturbance Decontamination

If asbestos has been disturbed accidentally — during renovation, drilling, or demolition — we provide emergency decontamination to make the area safe, followed by air monitoring to confirm fibre levels have returned to background.

Environmental Cleaning

Specialist cleaning of contaminated areas where asbestos fibres may have settled over time — including loft spaces, roof voids, plant rooms, and industrial units. Wet-wipe and HEPA vacuum methods throughout.

Equipment & Vehicle Decontamination

Decontamination of tools, plant, vehicles, and PPE that have been used in or near asbestos-containing areas. Essential for contractors working across multiple sites to prevent cross-contamination.

Air Clearance Testing

UKAS-accredited 4-stage clearance air testing to confirm that fibre concentrations are below the clearance indicator of 0.01 f/ml. A clearance certificate is issued on passing, confirming the area is safe for re-occupation.

Decontamination Documentation

Full written decontamination report, waste transfer notes, air monitoring results, and clearance certificate — all the documentation required for your records, insurers, and any future property sale.

The Process

How We Decontaminate Asbestos-Affected Areas

Initial Assessment

We assess the extent of contamination, identify all affected surfaces and materials, and agree a method statement with you before any works begin. For emergency call-outs following accidental disturbance, we can typically attend within 24 hours.

Area Isolation

The contaminated area is isolated using polythene sheeting and negative pressure units where required. This prevents fibre migration to adjacent areas during the decontamination process.

HEPA Vacuum Decontamination

All surfaces — floors, walls, ceilings, fixtures, and fittings — are systematically vacuumed using H-class HEPA-filtered vacuum equipment. HEPA filtration captures 99.97% of particles down to 0.3 microns, including asbestos fibres.

Wet-Wipe Cleaning

Following HEPA vacuuming, all surfaces are wet-wiped using damp cloths to remove any residual fibre contamination. Wet methods are used throughout to suppress fibre re-suspension. All contaminated materials are double-bagged and disposed of as asbestos waste.

Air Clearance Testing & Certification

On completion of decontamination, a UKAS-accredited analyst conducts the 4-stage clearance air test. If fibre concentrations are below 0.01 f/ml, a clearance certificate is issued confirming the area is safe for re-occupation. Results are typically available within 24 hours.
