What we repair

Remedial services.

Every job starts with an inspection to find the source of the problem, not just the symptom. You receive a written scope and itemised quotation before anything starts.

Defect rectification

Defects in your building report, fixed item by item.

We work through the defects listed in building, engineer and strata reports one at a time. Each item is priced, repaired and photographed, so you have evidence for every line.

Typical sources are building defect reports, builder’s warranty items and engineer schedules.

  • Review the report
  • Priced defect schedule
  • Repair each item
  • Photo evidence per item
  • Engineer or consultant sign-off
  • Evidence pack at handover

Problems we solve

Failed balconies and roofs

Tiles, screeds and membranes removed and renewed to Australian Standards.
