Licensed, Audited,
and Ready to Deliver

Residential Demolition

We regularly complete residential and apartment demolition projects. Our team handles service disconnections, salvages reusable materials, and clears sites safely, all while keeping neighbours in mind.

Commercial Demolition

From strip-outs to structural take-downs, we manage every phase of commercial demolition–including planning, permits, soft demolition, hazardous materials, and waste sorting. We collaborate closely with clients to deliver excellent results, safely and efficiently.

Industrial Demolition

We’ve handled complex projects across high-risk sites, including Transpower facilities and the deconstruction of a 100-year-old steel fabrication plant. Our experienced team understands the intricacies of  plant closures, live infrastructure, and hazardous environments.

Internal / Manual Demolition

Our manual demolition work is led by a Licensed Building Practitioner. With over 20 years of combined experience, we specialise in soft-strip and structural separation—particularly in live, sensitive buildings. We work cleanly and methodically, separating materials for timber recycling and landfill diversion as we go.

Not Just Demolition,
Deconstruction

We prioritise material recovery and recycling wherever possible. Our team separates, salvages, and processes on-site to reduce what ends up in landfill, without slowing down the programme

Examples of recovered materials:

  • Structural timber and framing
  • Aluminium, steel, and copper
  • Bricks, concrete, and aggregate

This approach is better for the environment, often more economical, and gives our clients peace of mind.
