Asbestos is a group of naturally occurring fibrous minerals known for their strength, heat resistance, and insulating properties. It was widely used in construction materials in New Zealand until the 1980s.

When disturbed, asbestos fibres become airborne and can be inhaled, leading to serious health issues such as asbestosis, lung cancer, and mesothelioma. These diseases may take years to develop after exposure.

Common locations include:

• Roofs, gutters, and downpipes
• Vinyl floor tiles and underlays
• Insulation materials
• Wall cladding and cement sheeting
• Textured ceilings

No, the importation and use of asbestos containing materials (ACMs) were banned in New Zealand in 2016. However, older buildings may still contain asbestos.

Testing is essential to determine the presence of asbestos containing materials (ACMs) before renovation, demolition, or maintenance work to prevent exposure to harmful fibres.

Certified professionals collect samples from suspected materials and send them to accredited laboratories for analysis.

Testing is recommended for:

• Homeowners planning renovations
• Property buyers of older homes
• Landlords ensuring compliance with Healthy Homes Standards
• Contractors and builders working on older buildings

Laboratory results typically take 3–5 working days. Urgent processing may be available at an additional cost.

It is not recommended. Improper handling of materials can release harmful fibres. Always hire a certified asbestos testing professional, like TechClean.

Asbestos removal is necessary when:

• Renovating or demolishing buildings with asbestos containing materials (ACMs)
• Damaged or deteriorating asbestos containing materials (ACMs) are present
• Health or safety risks are identified

The process includes:

• Identifying and assessing asbestos containing materials (ACMs)
• Preparing a removal plan in compliance with WorkSafe NZ guidelines
• Controlled removal by certified professionals
• Safe disposal of asbestos containing materials (ACMs) at licensed facilities

• Class A: Required for friable (easily crumbled) asbestos, such as insulation. This type poses a higher risk and needs stringent controls.
• Class B: For non-friable asbestos, like bonded cement sheeting, which is less likely to release fibres unless disturbed.

DIY removal of small quantities of non-friable asbestos is permitted but highly discouraged. Strict safety precautions must be followed. Hiring a certified professional ensures compliance and safety.

Look for WorkSafe NZ-approved certification, such as Class A or B licenses. TechClean holds both certifications, ensuring the highest safety standards.

Common signs include a musty odour, discolouration or black spots on walls, ceilings, or floors, and visible moisture or dampness. Allergic reactions like sneezing, itchy eyes, or respiratory problems can also indicate mould presence.

Yes, exposure to mould can cause health issues, especially for those with asthma, allergies, or compromised immune systems. It can trigger respiratory problems, skin irritation, and other allergic reactions.

TechClean uses a professional process involving identification, containment, removal, and prevention. We clean affected surfaces, use specialised equipment to treat hidden mould, and implement moisture control measures.

Small patches can sometimes be cleaned with vinegar or baking soda solutions, but larger infestations or toxic mould types require professional removal to prevent further spread and health risks.

Mould thrives in damp, humid environments. Common causes include water leaks, poor ventilation, and flooding.

Maintain proper ventilation, fix leaks promptly, use a dehumidifier in damp areas, and clean and dry surfaces regularly.

Meth contamination occurs when methamphetamine residue is left behind from its manufacture or use. It can pose significant health risks and reduce property value.

Signs include unusual chemical smells, discoloured walls, and reports of drug use or manufacture. Meth testing by professionals can confirm contamination levels.

TechClean follows a thorough process: testing to identify contamination levels, creating a decontamination plan, cleaning and treating affected areas, and post-clean testing to ensure safety.

Yes, exposure to meth residue can cause respiratory issues, headaches, skin irritation, and more severe health effects with prolonged exposure.

You should test before purchasing or renting a property, if the property has a history of suspicious activity, or if it’s located in a high-risk area for meth use or manufacture.

Yes, landlords are required to ensure properties meet health and safety standards. If meth contamination is detected, professional decontamination is essential.

Flood restoration involves removing water, drying affected areas, and cleaning surfaces to prevent mould and bacterial growth.

Fire restoration includes removing soot, smoke, and odours from affected areas, cleaning furniture and surfaces, and ensuring the property is safe to inhabit.

Restoration should begin as soon as possible to minimise further damage, such as mould growth after a flood or lingering smoke odours after a fire.

Most homeowner and commercial insurance policies cover restoration costs. Check your policy or contact your insurer for specific details.

It depends on the extent of damage and safety risks. TechClean can advise on the best course of action based on your situation.

The timeframe varies depending on the severity of the damage. TechClean provides tailored estimates after an initial assessment.

Regularly maintain your roof, plumbing, and drainage systems. Ensure proper ventilation and address leaks immediately.

Avoid touching or cleaning surfaces covered in soot, as improper cleaning can worsen damage. Contact professionals for an assessment and guidance.

Trauma cleaning involves the safe removal and decontamination of biological hazards resulting from incidents like accidents, deaths, or crime scenes. It includes sanitising affected areas and restoring them to safe conditions.

In most cases, property owners, landlords, or legal representatives are responsible for organising trauma cleaning. Insurance may cover the costs, so check your policy.

Yes, when performed by certified professionals like TechClean. We use advanced equipment and adhere to strict health and safety standards to minimise risks.

The time required depends on the extent of the damage and the size of the affected area. Most jobs are completed within one to two days.

Yes, odour removal is a key part of our trauma cleaning process to ensure the property is restored to a habitable state.

HAZMAT (Hazardous Materials) cleaning includes the removal and safe disposal of materials like chemicals, asbestos, or biohazards that pose a health or environmental risk.

TechClean technicians hold industry-standard certifications to handle hazardous materials safely and in compliance with New Zealand regulations.

We manage a range of materials, including chemical spills, asbestos, mould contamination, and other biohazards.

We follow WorkSafe NZ guidelines and use certified disposal methods to ensure compliance with health and environmental standards.

Yes, TechClean provides rapid response to contain and clean hazardous spills, minimising risks to health and the environment.

Bio cleaning is the removal and decontamination of biological hazards, such as mould, bodily fluids, or animal waste, to restore hygienic conditions.

Bio cleaning is essential when biohazards are present, such as after floods, pest infestations, or medical incidents.

Yes, our methods are safe and tailored to residential properties, ensuring thorough cleaning without causing harm to occupants.

Yes, TechClean can handle cleaning following pest infestations, including sanitising areas contaminated by droppings or nests.
