Managing Asbestos Safely During Property Projects

Older buildings can contain asbestos in places that are not immediately obvious. It may be present in roofing, ceilings, wall linings, flooring, insulation, soffits, or other building products. When renovation, maintenance, or demolition is planned, identifying these materials early can help property owners determine how the work should be approached.

The purpose of asbestos remediation is to manage or remove asbestos-containing materials in a controlled manner while reducing the possibility of fibre exposure and contamination. Depending on the circumstances, a project can involve assessment, testing, removal, cleaning, disposal, and restoration.

Begin With Identification

The first step is understanding whether asbestos is actually present.

Some asbestos-containing products can resemble ordinary building materials, making visual identification unreliable. Older property records may also be incomplete or unavailable.

Where asbestos is suspected, appropriate testing or an existing asbestos survey can provide useful information about the materials involved.

Knowing what is present allows the work to be planned before renovation or demolition begins.

Look at the Entire Property

Asbestos is not limited to one particular part of an older building.

Depending on the age and construction of a property, potentially affected materials may include:

• Textured ceiling finishes

• Cement-based wall sheets

• Roofing sheets and tiles

• Vinyl flooring

• Soffits and eaves

• Insulation

• Exterior cladding

The presence of one asbestos-containing product can also indicate the need to consider other areas of the building before major work starts.

Why Condition Matters

The condition of asbestos-containing material is an important part of the assessment.

Material that remains intact and undisturbed presents a different situation from material that has deteriorated or been damaged.

Renovation can also change the situation. Drilling, cutting, sanding, breaking, or removing an older material can disturb fibres that were previously contained within the product.

This is why suspected asbestos should be assessed before construction work begins.

Testing Helps Define the Scope

Testing can answer an important question: does the suspected material actually contain asbestos?

This can prevent unnecessary assumptions and help determine the appropriate next step.

For properties with an existing asbestos survey, the report may already provide information about the location and condition of relevant materials. A qualified contractor can review this information when developing the work plan.

Licensed Professionals

Asbestos work should not be treated like standard building maintenance.

The appropriate licensing and safety requirements depend on the type of asbestos and the work being undertaken. Professional contractors have the equipment, training, procedures, and controls required for regulated asbestos work.

AR Plus states that it holds both Class A and Class B asbestos removal licences and provides asbestos-related services throughout areas including Tauranga, Rotorua, Taupo, the Bay of Plenty, Waikato, Coromandel, and Gisborne. (arplus.nz)

Creating a Controlled Work Area

An important part of professional asbestos work is controlling the area where materials are being disturbed.

Depending on the project, this can involve isolating the work zone, establishing containment, controlling access, and using appropriate protective equipment and air-management systems.

The objective is to prevent unnecessary exposure and keep potential contamination within the designated work area.

Removal Requires Careful Techniques

The way asbestos-containing materials are handled can influence the level of risk.

Professional removal may use controlled, low-dust techniques and wet handling where appropriate. Specialist equipment can also be used to help manage dust and clean affected areas.

The exact procedure depends on the material and the conditions at the site.

Cleaning Is Part of the Process

Once asbestos-containing material has been removed, the surrounding area may still require careful cleaning.

Dust and residue need to be managed appropriately, and the work area may require decontamination before it can be returned to normal use.

A remediation project should therefore be considered complete only when the required removal, cleaning, and clearance procedures have been addressed.

Managing the Waste

Asbestos waste requires appropriate handling from the moment it is removed.

It needs to be packaged and transported according to applicable requirements and taken to an appropriate disposal facility.

This is an important consideration when arranging a project because waste management forms part of the overall removal process.

Residential Properties

Asbestos can be encountered in houses, particularly properties constructed or renovated during periods when asbestos-containing products were commonly used.

A residential project may involve a ceiling, bathroom wall lining, flooring, roofing, or exterior material.

Because people may continue living in the property during some stages of a project, planning access and work areas carefully is particularly important.

Commercial Buildings

Commercial projects can involve additional coordination.

Employees, customers, tenants, contractors, and visitors may all use the building, meaning asbestos work may need to be scheduled and controlled around normal activities.

Schools, offices, industrial properties, healthcare facilities, and other commercial environments can each present different challenges.

A site-specific plan is therefore more appropriate than relying on a standard procedure for every building.

Demolition and Renovation

Asbestos management can become especially important before demolition.

Older materials should be identified and appropriately dealt with before structural demolition begins. This can help prevent asbestos-containing products from being unintentionally broken apart during the demolition process.

For renovation projects, the same principle applies. If walls, ceilings, floors, or roofing are going to be disturbed, potential asbestos should be considered before work starts.

What Happens After Removal?

Removal can sometimes expose areas of a building that need to be rebuilt or refinished.

A ceiling may need new plasterboard. A wall may require replacement lining. A renovated area may need stopping, sanding, painting, or other finishing work.

Coordinating these activities can reduce delays between asbestos removal and the next phase of construction.

AR Plus provides additional property services including plastering, painting, ceiling restoration, demolition, and site clearance, which can support projects requiring work beyond asbestos removal. (arplus.nz)

Planning the Project

Good planning can make an asbestos-related project easier to manage.

Before work begins, property owners should establish:

• Where suspected asbestos is located

• Whether testing is required

• What type of material is involved

• Which areas need to be isolated

• How the material will be removed

• How waste will be handled

• Whether clearance is required

• Whether restoration will follow

Having these questions answered in advance can reduce uncertainty once work starts.

Don't Disturb Suspected Asbestos

If an older material appears suspicious, avoid disturbing it unnecessarily.

Cutting, sanding, drilling, breaking, or attempting to remove the material without appropriate controls can increase the possibility of fibre release.

Instead, stop the relevant work and seek professional advice about assessment and the appropriate next step.

Choosing the Right Contractor

When comparing asbestos contractors, look at the complete service rather than focusing exclusively on price.

Consider their relevant licences, experience, proposed safety measures, waste arrangements, cleaning procedures, and clearance process.

It is also useful to establish whether they can coordinate related building work if removal is part of a larger renovation or demolition project.

A Coordinated Approach

Asbestos work is often connected to a wider property project.

For example, a homeowner may need a ceiling removed before installing a new one, while a developer may need asbestos dealt with before demolition.

Having the different stages planned together can make the overall project more efficient and reduce the risk of one contractor waiting for another to complete their work.

Final Thoughts

Managing asbestos requires more than identifying an old building material and taking it out. The project needs to account for assessment, testing, site controls, removal methods, cleaning, waste disposal, clearance, and any restoration that follows.

For homeowners, landlords, builders, developers, and commercial property managers, addressing potential asbestos before renovation or demolition can make the project safer and more predictable.

The most sensible approach is to avoid disturbing suspected materials and obtain professional advice so the appropriate remediation strategy can be established for the individual property.
