Asbestos Vinyl Flooring Removal in Auckland: A Homeowner’s Guide

Asbestos Vinyl Flooring Removal in Auckland: What Homeowners Should Know

That faded vinyl in the kitchen may be ugly, but ugly is not the real problem.

Many older Auckland homes have vinyl flooring, floor tiles or backing materials that contain asbestos. It is often discovered when a homeowner begins renovating a kitchen, bathroom, laundry or toilet.

The vinyl may lift easily around the edges, tempting someone to grab a scraper and get stuck in. That is where a straightforward renovation can go sideways. Asbestos may be present in the vinyl itself, the paper-like backing, the adhesive underneath or more than one flooring layer.

Before pulling up old flooring, have it checked.

Which types of vinyl flooring may contain asbestos?

Asbestos was added to some flooring products because it improved strength, flexibility, insulation and resistance to heat and moisture.

It may be found in:

• Sheet vinyl flooring
• Vinyl floor tiles
• Paper or felt backing
• Black bitumen-based adhesive
• Flooring underlay
• Multiple layers of old flooring
• Adhesive or residue remaining on the subfloor

Kitchens, bathrooms, toilets and laundries are common locations because vinyl was a practical and affordable floor covering for wet areas.

Homes built before 1 January 2000 may contain asbestos materials. However, the age or pattern of a floor cannot confirm whether asbestos is present. Two vinyl products can look almost identical while only one contains asbestos.

Laboratory testing is the only reliable way to know.

How can I tell if my vinyl contains asbestos?

You generally cannot tell by looking at it.

Some homeowners hear that particular patterns, colours or manufacturers are “known asbestos products.” That may provide a clue, but it is not proof. Flooring may also have been installed years after the house was built, or an asbestos-containing layer may be hidden underneath newer vinyl, tiles or laminate flooring.

Possible warning signs include:

• Vinyl installed before 2000
• A paper-like backing beneath the vinyl
• Brittle tiles measuring approximately 225 mm or 300 mm square
• Black or dark adhesive under the flooring
• Several flooring layers laid over one another
• Old renovation records referring to asbestos
• Flooring that tears and leaves backing stuck to the floor

Do not break off a corner and place it in a plastic bag yourself. Sampling can release asbestos fibres, particularly if the backing is dry, damaged or crumbly. A suitably trained person should take a representative sample and send it to an accredited laboratory.

Is asbestos vinyl flooring dangerous?

Asbestos-containing vinyl that is in good condition and left undisturbed may present a relatively low risk. Problems arise when it is cut, drilled, sanded, scraped, ground or ripped from the floor.

The backing material can be more troublesome than the shiny surface you walk on. Pulling the vinyl upwards may tear the backing and leave fibrous material stuck to the subfloor. Aggressive scraping or sanding can then release fine asbestos dust.

Risk increases when:

• The flooring is damaged or lifting
• The backing is exposed
• Water damage has weakened the material
• Renovation work will disturb the floor
• Power tools are used
• Adhesive is sanded or ground away
• Flooring is broken into small pieces
• Dust and fragments are walked through the house

Asbestos fibres are microscopic. You cannot judge whether the air is safe because the room looks clean or because there is no obvious dust.

Can I remove asbestos vinyl flooring myself?

Homeowners should not treat asbestos vinyl removal as an ordinary DIY flooring job.

New Zealand’s asbestos rules distinguish between friable and non-friable asbestos. Non-friable material is asbestos bound tightly within another product. Friable asbestos can be crumbled or reduced to powder and presents a greater risk of airborne fibre release.

The classification of vinyl flooring can depend on its condition and the removal method. Some vinyl may initially appear non-friable, but tearing, scraping or separating the backing can make the material friable during removal.

WorkSafe New Zealand has specifically warned that work on some asbestos-containing vinyl flooring can change its condition from non-friable to friable.

Any amount of friable asbestos must be removed by a Class A licensed asbestos removalist. More than 10 square metres of non-friable asbestos must be removed by a Class A or Class B licensed asbestos removalist.

The 10-square-metre threshold should not be seen as a green light for DIY removal. Even unlicensed removal must be carried out by a competent person using proper controls and complying with New Zealand’s asbestos regulations.

Why cutting out the complete floor can sometimes be safer

In some homes, a safer option may be to remove the asbestos vinyl together with the flooring substrate underneath it.

For example, if the vinyl is firmly bonded to a removable timber or sheet flooring panel, it may be possible to cut out and remove the complete floor section while keeping the asbestos material attached and substantially intact.

This can avoid peeling the vinyl from its backing or grinding adhesive from the floor.

However, this method is not suitable for every property. Before work begins, the contractor must consider:

• The laboratory results
• Condition of the vinyl and backing
• Type of subfloor
• Pipes, wiring and services beneath the floor
• Structural implications
• Total area being removed
• Potential for the material to become friable
• Correct licence classification
• Dust created by cutting the flooring substrate

Cutting out the floor does not automatically make the work Class B. The classification must be determined from the material, its condition and the actual removal method.

What happens during professional asbestos vinyl removal?

Every property is different, but the work generally involves the following stages.

1. Inspection and asbestos testing

The flooring layers are examined and representative samples are sent to an accredited laboratory. More than one sample may be needed if the rooms contain different vinyl, backing or adhesive products.

2. Selecting the removal method

The contractor considers whether the vinyl can be removed intact, whether the subfloor should be cut out or whether the method will create friable asbestos.

This decision determines the licence and controls required.

3. Preparing the work area

Furniture, appliances and loose belongings are removed where it is safe to do so. The work area is isolated using barriers, warning signs and sealed access points.

Depending on the classification and risk, additional controls may include:

• Heavy-duty polythene sheeting
• A sealed enclosure
• Negative-pressure equipment
• HEPA-filtered extraction
• Decontamination facilities
• Air monitoring
• Controlled entry and exit procedures

4. Controlled removal

The flooring is kept damp where appropriate and removed using methods that minimise breakage and fibre release.

High-speed sanding, dry grinding, ordinary vacuum cleaners and uncontrolled scraping are not acceptable ways to remove asbestos flooring.

5. Decontamination and waste disposal

Asbestos vinyl, removed subfloor, disposable protective equipment and contaminated materials are correctly wrapped or bagged, labelled and transported to an approved asbestos-waste facility.

The work area and reusable equipment are then thoroughly decontaminated.

6. Clearance

The area must be inspected before homeowners, builders or flooring contractors return.

The clearance requirements depend on whether the work was Class A, Class B or permitted unlicensed removal. Class A asbestos removal requires clearance by an independent licensed asbestos assessor.

Do not allow a builder, plumber, flooring installer or painter into the restricted area until the required clearance has been completed.

Can new flooring be installed over asbestos vinyl?

Sometimes an intact asbestos-containing floor can be covered rather than removed.

This may be considered when:

• The flooring is in sound condition
• It is firmly bonded to the floor
• It will not be drilled or disturbed
• The new floor system is compatible
• Services beneath the floor will not require access
• The asbestos material can be recorded for future owners and contractors

Covering the floor does not remove the asbestos. It remains part of the building and must be managed in the future.

Removal may be the better option when the vinyl is damaged, lifting, water-affected or likely to be disturbed by renovations.

How much does asbestos vinyl removal cost in Auckland?

There is no dependable flat rate without inspecting the property. A small toilet with accessible sheet flooring is very different from a kitchen containing several layers of vinyl, adhesive and particleboard.

The price may be affected by:

• Total floor area
• Number of rooms
• Laboratory testing
• Type and condition of the vinyl
• Whether the backing is friable
• Amount of furniture or cabinetry
• Access beneath the floor
• Removal of toilets, appliances or fittings
• Whether the subfloor must be cut out
• Enclosure and decontamination requirements
• Air monitoring and clearance
• Asbestos-waste charges
• New flooring or subfloor reinstatement

When comparing quotations, check whether the price includes testing, waste disposal, clearance and removal of the flooring substrate. A cheap figure can become expensive once all the missing pieces are added.

How should homeowners prepare?

Your asbestos removal contractor should provide instructions specific to the job. You may be asked to:

• Empty cupboards near the work area
• Remove food, towels and personal items
• Arrange for appliances to be disconnected
• Keep children and pets away
• Provide access to water and electricity
• Tell the contractor about underfloor wiring and plumbing
• Arrange alternative accommodation if necessary
• Notify other trades that asbestos work is taking place

Do not begin lifting the flooring to “make things easier” before the removalist arrives. Leaving the material undisturbed is usually the safer option.

Choosing an asbestos flooring removal contractor

Before accepting a quote, ask the contractor:

• Has every suspect flooring layer been tested?
• Is the vinyl or backing friable?
• What licence class does the work require?
• How will the flooring be removed?
• Will the vinyl be lifted or removed with the subfloor?
• How will dust and fibres be controlled?
• Is asbestos-waste disposal included?
• Will an independent clearance be required?
• Who is responsible for disconnecting appliances and services?
• Does the quotation include floor reinstatement?
• When can the household safely use the room again?

You can check licensed asbestos removalists through WorkSafe New Zealand’s public licence-holder register.

Asbestos vinyl removal with PropertyHelp Ltd

PropertyHelp Ltd provides asbestos inspection support and Class B asbestos removal services for homeowners throughout Auckland.

Where the vinyl and removal method meet the requirements for non-friable asbestos work, PropertyHelp Ltd can assess and undertake the work using appropriate Class B removal controls. One possible method is removing the vinyl with the floor substrate so the asbestos-containing material remains attached and is not scraped into pieces.

Every job must be assessed individually. If the vinyl backing or proposed removal method makes the material friable, the work must be completed under the appropriate Class A asbestos removal licence.

PropertyHelp Ltd can help homeowners understand:

• Whether asbestos testing is needed
• What the laboratory results mean
• Which licence class is required
• Whether the flooring can remain in place
• Whether the complete floor should be removed
• How the room will be isolated
• What is included in the quotation
• What clearance requirements apply
• When renovation work can safely continue

The advice is practical and easy to follow. You will know what is being removed, how it will be controlled and what needs to happen before your new flooring goes down.

Test before you pull up that corner

Finding asbestos does not mean your renovation has reached the end of the road. It simply means the flooring needs to be dealt with properly.

The expensive mistake is discovering asbestos after the vinyl has been ripped apart and carried through the house.

If your Auckland home has old vinyl flooring, arrange testing before demolition or renovation begins. For advice about asbestos vinyl testing and asbestos vinyl flooring removal in Auckland, contact PropertyHelp Ltd to discuss your property and the work you are planning.

A sample taken at the right time can prevent a room-sized job from becoming a whole-house clean-up.
