NCAT Expert Witness Reports

If you are involved in a building dispute, an independent expert report can help explain the building issues, document visible defects and provide an informed opinion regarding likely causes and appropriate rectification works.

Sydney Building Consultants prepares detailed NCAT Expert Witness Reports for matters involving defective, incomplete, poor-quality or disputed building work.

Our reports may include:

  • Site inspection findings
  • Detailed photographs
  • Identified building defects
  • Observations regarding workmanship
  • Assessment of likely causes of defects
  • Waterproofing and water-ingress findings
  • Recommended rectification works
  • Defect schedules where required
  • Review of available plans, contracts, quotes and building documents
  • Independent expert opinion for NCAT and litigation-support matters

Our reports are independently prepared and are designed to assist clients in understanding the building issues and presenting the evidence in a clear, professional and practical format.

  • Homeowners and property owners

Building Defect Reports

Building defects can occur in new homes, renovations, extensions, apartments, townhouses, investment properties and commercial premises. Some building defects are immediately visible, while others only become apparent after leaking, cracking, movement, mould, water damage or deterioration occurs.

Sydney Building Consultants carries out detailed building defect inspections and reports for issues including:

  • Defective building work
  • Poor workmanship
  • Incomplete building works
  • Renovation defects
  • Extension defects
  • New home building defects
  • Cracking to walls, ceilings, floors and external finishes
  • Tiling defects
  • Roof leaks
  • Water ingress
  • Balcony and terrace defects
  • Internal and external water damage
  • Non-compliant construction concerns
  • Building damage arising from works
  • Disputes about rectification works
  • Independent second opinions on building reports or builder proposals

We inspect the observed condition of the building, identify defects where possible and provide clear recommendations regarding the next steps and rectification considerations.

Waterproofing Investigations

Waterproofing defects can lead to extensive and expensive building damage if they are not identified and rectified correctly. Water can travel through tiles, membranes, wall cavities, floor structures, joints and service penetrations before becoming visible.

A leaking ceiling, damaged paintwork, mould growth, swollen skirting boards, loose tiles or musty odours may be symptoms of a concealed waterproofing defect, plumbing issue or water-ingress problem.

Sydney Building Consultants provides independent waterproofing investigations for residential and commercial properties.

Our waterproofing investigation services include:

  • Bathroom waterproofing defect investigations
  • Shower recess leak inspections
  • Leaking bathroom inspections
  • Waterproofing membrane failure assessments
  • Balcony waterproofing inspections
  • Terrace waterproofing investigations
  • Laundry waterproofing inspections
  • Water ingress investigations
  • Dampness and moisture assessments
  • Mould-related building damage inspections
  • Tiling, grout and sealant defect assessments
  • Poor drainage and floor fall concerns
  • Wet-area construction defects
  • Water damage to ceilings below bathrooms or balconies

Where appropriate, our assessment may consider visible site conditions, construction methods, available documentation, building practices and relevant Australian Standards.

Bathroom Leak and Shower Leak Reports

A leaking shower or bathroom should be properly investigated before repairs are carried out. Replacing grout, silicone or tiles without identifying the true source of the leak can result in unnecessary costs and recurring water damage.

Sydney Building Consultants investigates bathroom leaks, shower leaks and wet-area water ingress to help clients understand the likely cause, extent and impact of the issue.

Common signs of bathroom or shower waterproofing failure include:

  • Water stains on ceilings below a bathroom
  • Damp walls
  • Swollen skirting boards
  • Loose, cracked or drummy tiles
  • Mould growth or musty odours
  • Peeling paint
  • Water escaping from shower areas
  • Cracked grout
  • Failed silicone sealant
  • Deteriorated wall and floor joints
  • Water pooling on bathroom floors
  • Leaks affecting adjoining rooms
  • Damage to timber flooring, carpets or cabinetry

Our report can assist in identifying whether the issue may relate to waterproofing, tiling, drainage, poor falls, plumbing interfaces, fixtures, building movement or another contributing cause.
