Envirosphere Consulting provides professional asbestos sampling and testing for residential, commercial and industrial properties throughout Auckland, Northland and Waikato.
If you have a specific building material that may contain asbestos, we can assess the material, collect a representative sample using appropriate controls and submit it to an IANZ-accredited laboratory for analysis.
Once laboratory results are received, we provide clear documentation of the results and practical advice on the appropriate next steps where asbestos is identified.

Cladding, soffits, roofing, internal linings and other fibre cement building products may contain asbestos, particularly in older buildings.
Vinyl tiles, sheet flooring, backing materials and some associated flooring products may contain asbestos.
Decorative and textured coatings applied to ceilings and walls may contain asbestos and should be assessed before disturbance.
Some historic bituminous and other flooring coverings may contain asbestos and can require assessment before refurbishment or flooring removal.
Fibre cement roofing and some historic bituminous roofing products and components may contain asbestos.
Some historic thermal insulation, pipe insulation, sprayed fireproofing and acoustic coatings can contain asbestos and may present a higher risk when disturbed.
Asbestos cannot be reliably confirmed or ruled out by appearance alone. Where a material is suspected of containing asbestos, representative sampling and laboratory analysis can be used to determine whether asbestos is present.
We discuss the suspect material, property and proposed work to determine whether targeted asbestos testing is appropriate or whether a more comprehensive asbestos survey may be required.
A representative sample of the suspect material is collected using appropriate controls to minimise disturbance and potential fibre release. The material and sample location are documented.
Decorative and textured coatings applied to ceilings and walls may contain asbestos and should be assessed before disturbance.
Once laboratory results are received, Envirosphere provides clear documentation of the analytical result. Where asbestos is detected, we can provide practical advice regarding management, removal or further assessment.
Targeted asbestos testing is appropriate when a specific material or small number of materials need to be assessed to determine whether asbestos is present.
An asbestos survey involves a systematic assessment of an agreed area or building to identify asbestos-containing materials that may be present. The appropriate survey type depends on how the property is being used and whether refurbishment or demolition work is planned.
If significant renovation or demolition work is proposed, testing one or two individual materials may not provide sufficient information. A refurbishment or demolition asbestos survey may be more appropriate.
Envirosphere Consulting can help determine the appropriate level of assessment for your property or project.
A positive asbestos result does not automatically mean that the material needs to be removed immediately.
The appropriate response depends on factors including the type of asbestos-containing material, its condition and location, whether it is likely to be disturbed and any planned refurbishment, maintenance or demolition work.
Depending on the circumstances, the material may be able to remain in place and be appropriately managed, or removal may be recommended before work proceeds.
Envirosphere Consulting can provide advice on the appropriate next steps and, where removal is required, assist with project oversight, air monitoring and independent clearance inspections.

No. While some asbestos-containing materials may have recognisable characteristics, visual inspection alone cannot reliably confirm whether asbestos is present. Laboratory analysis of a representative sample is used to confirm the result.
We aim to get lab results within 24 hours of attending site.
If planned work may disturb building materials that could contain asbestos, those materials should be appropriately assessed before disturbance. Depending on the extent of the proposed work, a refurbishment asbestos survey may be more appropriate than targeted testing.
The appropriate next step depends on the material, condition, location and proposed work. Asbestos-containing materials do not always require immediate removal and may sometimes be safely managed in place.
Asbestos testing is often the first step in understanding whether asbestos-containing materials are present. Depending on the results and your planned work, you may also require an asbestos survey, asbestos air monitoring, or an independent asbestos clearance inspection.
Envirosphere Consulting provides asbestos consultancy services across Auckland, Northland and Waikato.
If you have discovered a suspect building material or are planning work that may disturb materials that could contain asbestos, Envirosphere Consulting can help determine the appropriate next step.
