Asbestos Shed & Outbuilding Removal

Older sheds and outbuildings can contain asbestos-cement sheets, but age and appearance alone cannot confirm asbestos. Pro Asbestos Removal carries out owner-led non-licensed and NNLW dismantling/removal within its confirmed scope; licensable work must be handled by an HSE-licensed contractor.

Pro Asbestos Removal carries out non-licensed and notifiable non-licensed asbestos work only. If a job is classed as licensable, it must be handled by an HSE-licensed contractor.

The Risk You Can't See

Asbestos-cement sheets can weather, crack or be damaged over time. If suspect material is damaged or planned work will disturb it, avoid cutting, breaking or cleaning it until the material and work category have been assessed.

Inhaling asbestos fibres can lead to severe and often fatal respiratory diseases, including mesothelioma, asbestosis, and lung cancer, which typically manifest decades after exposure. If a sale or renovation is planned, keep reliable asbestos information with the property records and obtain job-specific advice where the material may be disturbed.

Where the duty to manage applies, the dutyholder must identify and manage asbestos risk and provide relevant information to people who may disturb ACMs. Domestic and non-domestic duties differ, so this page does not turn Regulation 4 into a blanket homeowner obligation.

How Asbestos Cement Degrades and Why Fibre Release Accelerates

Asbestos cement products, such as corrugated sheets and flat panels, typically contain chrysotile (white asbestos) and sometimes amosite (brown asbestos) fibres embedded within a cement matrix. Over decades, exposure to rain, frost, UV radiation, and physical disturbance causes the cement to erode and become friable. This degradation process loosens the asbestos fibres, making them highly susceptible to release into the atmosphere with minimal agitation.

The primary risk pathway is inhalation of these airborne fibres. Once inhaled, the sharp, durable fibres can become lodged in the lungs and pleura, leading to cellular damage and inflammation that can progress to serious diseases. The Workplace Exposure Limit (WEL) for asbestos fibres, as defined in HSE document EH40, is 0.1 fibres per cubic centimetre (f/cm³) averaged over a 4-hour period, highlighting the extremely low threshold for safe exposure.

Even seemingly intact asbestos cement can pose a risk. Impact from falling objects, drilling, cutting, or even vigorous cleaning can cause significant fibre release. The long latency period of asbestos-related diseases means that exposures occurring today could lead to illness many years in the future, underscoring the importance of professional, controlled removal to prevent future health consequences.

If suspect asbestos will be disturbed, establish the material and work category before dismantling begins.

What the Service Includes

Careful handling to minimise fibre release
Asbestos waste handled through the applicable legal route
Site cleared and left tidy on completion
Concrete bases and footings removed on request

How We Work

Quotation Assessment

We review the structure, access and suspected material to define the quotation scope. This is not a formal asbestos survey and cannot confirm asbestos by appearance.

Work Plan

The task is classified and the job-specific risk assessment and work plan set out the controls for work within our direct scope.

Owner-Led Work

Non-licensed/NNLW work within scope is carried out using the controls required by the assessed material and task. Licensable work is not undertaken directly.

Waste & Handover

Asbestos waste follows the applicable hazardous-waste route and customers receive the legally required paperwork for the job and waste movement.

When You Need to Act

Visible damage or cracks in shed materials

Avoid further disturbance and arrange assessment of the material, condition and work route.

Planning renovations or demolition of the shed

Establish what material is present and the correct work category before renovation or demolition begins.

Shed built before 2000 with suspect materials

Age alone cannot confirm asbestos content or condition. Use an appropriate sampling or survey route where identification is needed.

General deterioration of an older outbuilding

Arrange an assessment before work that could disturb the material; the condition and planned task determine the route.

Before Work Starts

The most expensive mistake in asbestos shed removal is attempting a DIY demolition without proper training or equipment. This inevitably leads to uncontrolled fibre release, contaminating your property and potentially your neighbours\' properties, incurring significant remediation costs and potential legal action.

Our Approach

For work within our confirmed non-licensed/NNLW scope, the quotation defines the material, agreed structure and waste route. The job-specific risk assessment and work plan determine the controls rather than a one-size-fits-all dismantling method.

Common Questions

Does my shed contain asbestos?

Older corrugated or flat sheet products may contain asbestos cement, but appearance alone cannot confirm it. Where confirmation is needed, use an appropriate sampling or survey route before work that could disturb the material.

Can I remove an asbestos shed myself?

Some asbestos-cement work can be non-licensed, but that does not make every DIY task appropriate. Competence, risk assessment, controls and the waste route still apply, and licensable work requires an HSE-licensed contractor.
