Magnesite Removal Before Settlement: The Special Condition Buyers Should Ask For When an Apartment Floor Looks Uneven

When an uneven floor in an older Sydney apartment may conceal magnesite, a buyer should ask their NSW solicitor or conveyancer to negotiate a special condition before exchange. The condition should not merely require the vendor to “fix the floor”. It should define access, investigation, strata approval, removal scope, contractor responsibility, inspection hold points, completion evidence and the remedy if hidden slab damage or incomplete work remains at settlement.

An uneven apartment floor is often priced as a future renovation item. A buyer notices a ridge beneath the carpet, a soft transition near the balcony door or a room that feels slightly higher at one end. The problem is added to a list with painting, joinery and new flooring, then deferred until after settlement.

In an older Sydney strata building, that assumption can be commercially dangerous.

Unevenness does not prove that magnesite is present or that the concrete slab is damaged. It may come from worn underlay, previous patching, a screed transition, old adhesive, local slab variation or a poorly installed floor finish. However, where magnesite topping is present, removing the visible flooring may expose a much broader sequence involving demolition, waste handling, concrete assessment, grinding, repairs, levelling, acoustic compliance and strata approval.

The issue is therefore not only whether the buyer can afford to remove an old floor. It is whether the contract gives the buyer a workable response before ownership, access, contractor bookings and settlement funds become locked into place.

The Floor Is a Transaction Signal, Not a Visual Diagnosis

Buyers should resist two opposite mistakes. The first is assuming that every uneven floor is evidence of serious slab deterioration. The second is treating the problem as cosmetic because the existing carpet or floating floor remains usable.

A visual inspection cannot reliably establish what lies beneath the floor finish. Even where the topping is exposed at a cupboard edge or doorway, the visible section may not represent the condition across the apartment. A useful assessment may need to distinguish between:

  • The decorative floor covering and underlay
  • Magnesite, screed, adhesive or previous levelling material
  • The structural concrete slab
  • Localised patching or earlier remedial work
  • Moisture entry from balconies, windows, wet areas or plumbing
  • Changes in height between rooms and different floor systems

Buyers arranging an inspection should document the floor systematically rather than relying on one photograph. Elyment’s guide to photographing magnesite flooring before requesting removal quotes explains why doorway transitions, perimeter edges, staining, cracking and access conditions need to be recorded separately.

NSW Government guidance recommends obtaining relevant inspection reports before exchange because significant physical problems can be costly once the contract becomes binding. Where the proposed investigation involves lifting flooring, sampling material or opening a concealed edge, the buyer will also need the vendor’s written consent.

Why the Standard Settlement Process May Leave a Gap

NSW buyers are advised to review the sale contract, settlement details and special conditions before signing. This is particularly important where the physical condition of the floor is central to the purchase decision.

The ordinary conveyancing process does not automatically give a buyer the right to enter the apartment, remove flooring, appoint contractors or direct the vendor’s renovation work before settlement. Under the standard NSW contract structure, legal title and possession ordinarily pass at completion.

A final inspection is also narrower than many buyers assume. Its usual purpose is to confirm that the property remains in substantially the same condition as when contracts were exchanged. It is not automatically a technical certification that magnesite has been removed correctly, that the concrete is suitable for new flooring or that an agreed remediation scope has been completed.

If the buyer wants investigation, removal or rectification to occur before settlement, the contract needs to deal with that outcome directly.

This becomes even more important at auction. Once the hammer falls, the successful bidder is generally legally committed to the purchase. Any requested floor condition should therefore be negotiated, accepted and inserted into the contract before bidding, not raised after the auction has concluded.

The Special Condition Should Control an Outcome, Not Promise a “Good Floor”

A vague condition stating that the vendor will “repair the uneven floor” can create more disagreement than protection. It does not identify the material to be removed, the area covered, the required standard, who selects the contractor or what happens if removal exposes concrete deterioration.

The more useful approach is to ask the buyer’s NSW solicitor or licensed conveyancer to prepare a condition addressing four connected stages:

  1. Investigation: What access, inspection or testing must be permitted?
  2. Removal: What material and floor area must be removed, by whom and under what approvals?
  3. Verification: What evidence must demonstrate that the agreed scope has been completed?
  4. Failure response: What contractual consequence applies if the work is incomplete or a more serious condition is discovered?

The condition must be drafted for the specific transaction. It should not be copied from a contractor’s quote, an online template or an agent’s email.

Important: The following is an operational checklist, not model legal wording. A NSW solicitor or licensed conveyancer should draft or approve the actual special condition and consider the lender’s requirements.


What the Condition Needs to Define

Area and material

What should be clarified

The rooms, approximate square metres and material believed to require removal.

Why it matters operationally

Prevents a contractor treating one visible patch while leaving connected areas outside the scope.


Investigation access

What should be clarified

Who may enter, when access is available and whether lifting, sampling or non-destructive testing is authorised.

Why it matters operationally

A buyer does not ordinarily control the apartment before settlement.


Strata approval

What should be clarified

Who must obtain approval, provide notices, submit flooring details and arrange lift or common-area protection.

Why it matters operationally

Floor changes, demolition and noisy works may require building-specific approval.


Contractor appointment

What should be clarified

Whether the vendor, buyer or another party selects and contracts the removal company.

Why it matters operationally

The contracting party controls payment, instructions, variations and warranty rights.


Removal endpoint

What should be clarified

Whether the scope stops at exposed magnesite, complete removal to the concrete slab or another clearly defined substrate.

Why it matters operationally

“Remove the old floor” may otherwise mean removing only carpet or boards.


Hazardous-material review

What should be clarified

Whether older adhesives, vinyl, underlay or associated products require sampling before disturbance.

Why it matters operationally

Asbestos cannot be cleared by appearance alone, particularly in older properties.


Post-removal hold point

What should be clarified

Who inspects the slab after removal and before patching, levelling or covering begins.

Why it matters operationally

Removal may reveal information that cannot be seen while the topping remains in place.


Engineering escalation

What should be clarified

What evidence triggers assessment by a structural or remedial engineer.

Why it matters operationally

Flooring contractors should not be expected to certify structural concrete.


Surface preparation

What should be clarified

Whether grinding, adhesive removal, local repair or levelling is included or excluded.

Why it matters operationally

A bare slab is not automatically ready for a new floor finish.


Waste and common areas

What should be clarified

Waste route, lift bookings, protection, disposal and final cleaning responsibilities.

Why it matters operationally

Apartment access can materially affect labour, timing and building approval.


Completion evidence

What should be clarified

Required photographs, invoices, approvals, test results, disposal records or professional reports.

Why it matters operationally

A verbal assurance from the agent may not demonstrate what work was completed.


Buyer verification

What should be clarified

Whether the buyer or their consultant may inspect after removal and before settlement.

Why it matters operationally

The ordinary final inspection may be too late to correct an incomplete technical scope.


Failure remedy

What should be clarified

The agreed response if work is late, incomplete, non-compliant or reveals a materially different condition.

Why it matters operationally

Any right to delay, adjust, retain funds or terminate must be expressly and legally documented.


Damage and insurance

What should be clarified

Responsibility for damage to the lot, common property, services or neighbouring apartments.

Why it matters operationally

Pre-settlement demolition creates risks while the vendor still owns the property.


Four Commercial Structures Buyers May Need to Compare

Requiring the vendor to remove magnesite before settlement is not always the only or best commercial solution. The parties may consider several structures, each of which has different legal, lending and delivery consequences.

Vendor completes removal before settlement

Potential advantage

The physical condition can be exposed while the transaction remains subject to the agreed condition.

Primary risk

The vendor may choose the contractor, minimise the scope or resist responsibility for hidden slab work.


Purchase price adjustment

Potential advantage

The buyer can control the contractor, specification and final flooring system after settlement.

Primary risk

The agreed reduction may be insufficient if the true condition remains concealed.


Settlement retention

Potential advantage

A defined amount may remain available while specified work or evidence is completed.

Primary risk

The mechanism requires precise drafting and may need lender and stakeholder agreement.


Conditional extension or staged response

Potential advantage

Allows time for assessment if removal exposes a materially different condition.

Primary risk

Delayed settlement may affect finance, accommodation, removalists and booked trades.

Buyers should not choose between these options solely by comparing an estimated removal rate per square metre. The appropriate structure depends on the uncertainty beneath the floor, the vendor’s cooperation, the strata approval pathway, the buyer’s finance and the consequences of a delayed settlement.

Strata Approval Does Not Follow Automatically From the Sale Contract

A special condition binds the parties to the sale contract. It does not automatically bind the owners corporation or override the building’s by-laws.

NSW strata guidance states that approval may be required when changing floors and that owners should check their scheme’s by-laws before renovation work begins. A building may also require acoustic documentation, contractor insurance, a work method, resident notices, security deposits, lift bookings and protection of common property.

Responsibility for the magnesite, screed or affected concrete may also depend on the strata plan, the building’s history and whether the relevant component is classified as lot property or common property. Buyers should avoid assuming that either the future lot owner or the owners corporation will automatically pay for every layer beneath the carpet.

Elyment’s analysis of common-property questions before renovating an apartment floor explains why the ownership boundary should be investigated before removal or repair responsibilities are assigned.

The special condition should therefore identify who is responsible for seeking strata approval and what happens if approval is delayed, refused or granted with additional requirements.


What Removal May Reveal Beneath the Apartment

Magnesite removal is an investigative event as well as a demolition task. The exposed floor may lead to several very different project pathways.


1. A Generally Stable Slab Requiring Preparation

The topping may be removed without discovering significant concrete deterioration. The remaining work may involve residue removal, controlled concrete grinding, local patching, priming and floor levelling before the selected floor system is installed.

Even in this outcome, the slab should be assessed against the requirements of the proposed flooring product. Elyment’s article on concrete grinding and levelling-compound bond preparation explains why a visually clean surface may still be unsuitable for the next system.

2. Localised Moisture or Degraded Topping

Removal may expose damp areas near balcony doors, bathrooms, laundries, windows or previous plumbing locations. The project team then needs to investigate the moisture source before reinstating the floor. Covering the area quickly may conceal the evidence without resolving the cause.

3. Concrete Cracking, Spalling or Suspected Reinforcement Corrosion

Where the slab shows significant cracking, loose concrete, corrosion staining or other structural concerns, the matter may move beyond ordinary flooring preparation. A remedial or structural engineer may need to determine the extent of assessment and repair.

The special condition should not force a flooring contractor to declare the slab structurally satisfactory. It should establish an escalation process and identify who pays for further assessment.

4. A Broader Level and Threshold Problem

Removing magnesite can change the finished floor height across doorways, kitchens, bathrooms and adjoining rooms. The buyer may need a new build-up incorporating repair mortar, levelling compound, acoustic underlay and the final floor finish.

A removal condition that ignores the required finished height may solve the hidden-material problem while creating new issues with doors, skirting, appliances, balcony thresholds and wet-area transitions.


Pre-Settlement Removal Requires a Controlled Worksite

The apartment remains part of an occupied building while removal is taking place. A commercially useful condition therefore needs to support a workable site plan, not merely authorise demolition.

The operational plan may need to address:


  • Approved working days and noisy-work hours
  • Access to the apartment, loading area and parking
  • Lift reservations and protection of corridors, doors and thresholds
  • Isolation or protection of smoke detectors and building services where lawfully permitted
  • Dust extraction, containment and daily cleaning
  • Waste packaging, movement and legal disposal
  • Protection of joinery, walls and retained finishes
  • Neighbour and building-manager communication
  • Contingency time if hidden conditions stop the work

Where removal or subsequent grinding affects concrete, SafeWork NSW requires appropriate controls for respirable crystalline silica. Depending on the activity, controls may include on-tool dust capture, wet methods, exclusion zones, suitable respiratory protection and safe cleaning procedures.

Older floor coverings, underlays, adhesives and associated materials may also require an asbestos review. NSW asbestos guidance states that asbestos cannot be reliably identified by appearance and recommends testing before renovation or demolition where suspect materials may be disturbed.

The condition should allow the work to pause safely if testing or a professional assessment becomes necessary. A settlement deadline should not pressure contractors into disturbing an unidentified material.


The Hold Point After Removal Is the Most Valuable Stage

One of the strongest protections is a formal hold point after the old topping has been removed but before the slab is patched, levelled or covered.

At this stage, the buyer’s nominated consultant may be able to record:


  • The actual extent and thickness of the removed material
  • Visible cracking, staining, spalling or previous repair areas
  • Residual adhesive, screed or friable material
  • Changes in slab height and doorway transitions
  • Areas requiring engineering or moisture investigation
  • The likely preparation pathway for the proposed new flooring

Without this hold point, a vendor may complete removal and immediately apply a patching or levelling product. The floor may look smooth at final inspection, but the buyer may lose the opportunity to understand what was exposed and how it was treated.

Completion Evidence Should Be Agreed Before Work Starts

Evidence requirements should be proportionate to the risk. A straightforward removal may not require the same documentation as a project involving concrete repairs or hazardous-material removal.

Depending on the agreed scope, the buyer’s solicitor or conveyancer may consider requiring:

  • Dated photographs before, during and after removal
  • The contractor’s written scope and invoice
  • Strata or building-manager approval
  • Evidence of contractor insurance or licensing where applicable
  • Material testing reports
  • Waste or disposal documentation where required
  • An engineer’s report where structural concerns were identified
  • A record of the substrate condition before it was covered
  • Details of any primer, repair or levelling system installed
  • Confirmation that common areas were cleaned and any damage rectified

Invoices and photographs are useful records, but they do not automatically establish technical compliance. The contract should identify whether professional certification or inspection is required for the particular risk.


Settlement Timing Must Follow the Work, Not the Contractor’s Optimism

A removal contractor may complete demolition in a short period, but the overall programme can expand when approvals, testing, engineering, repairs or drying periods are included.

Buyers should allow for the possibility that:


  • Strata approval takes longer than expected
  • The building offers limited lift or loading access
  • Material testing delays physical work
  • The exposed slab requires engineering review
  • Repair products need curing time
  • Final levels cannot be confirmed until the entire topping is removed
  • The vendor disputes whether additional work falls within the agreed scope

Elyment’s analysis of settlement delays and pre-booked renovation trades shows why flooring removal, levelling and installation should not be treated as fixed calendar events until access and property control are confirmed.

Buyers planning hybrid, timber or other hard flooring should also coordinate acoustic approval before ordering materials. The relationship between acoustic underlay, strata approval and apartment flooring installation may affect both the finished height and the permitted system.

Questions the Buyer’s Team Should Resolve Before Exchange

  1. What evidence suggests that the unevenness involves magnesite rather than the visible flooring?
  2. Has the seller permitted a suitable floor inspection or material test?
  3. Are there strata records mentioning magnesite removal, leaks, slab repairs or concrete deterioration?
  4. Does the strata plan or professional advice clarify the relevant property boundary?
  5. What work can legally and practically occur before settlement?
  6. Who will appoint, instruct and pay the contractor?
  7. What exactly must be removed?
  8. Who inspects the exposed slab?
  9. What triggers an engineering assessment?
  10. What documents must be supplied before completion?
  11. What happens if strata approval or contractor access is delayed?
  12. What contractual remedy applies if the agreed outcome is not delivered?
  13. Has the buyer’s lender been informed of any unusual settlement arrangement?

Understand the Floor Risk Before It Becomes a Settlement Problem

Review removal scope, access, strata requirements, substrate uncertainty, contractor sequencing and the practical evidence needed before renovation commitments are made.

The Contract Should Preserve Choices, Not Create Another Unknown

The central lesson is not that every buyer should force a vendor to remove magnesite before settlement. In some transactions, vendor-managed removal will provide valuable information. In others, a properly calculated price adjustment or buyer-controlled project after settlement may be more practical.

What buyers should avoid is an informal promise that the floor will be “sorted out”.

When an apartment floor looks uneven, the proposed special condition should connect the legal transaction to the real renovation workflow. It should identify what can be investigated, what must be removed, who controls the work, when the exposed slab is reviewed and what happens if the condition is materially different from what the parties expected.

That is how an uncertain floor becomes a manageable acquisition issue rather than an unpriced project discovered after the keys are released.
