Office & Commercial Demolition — Cairns, Townsville & Mackay

Whether you're refitting a single tenancy or clearing an entire floor, we deliver professional office demolition across North Queensland — including live, occupied buildings.

What the service involves

We specialise in live-building demolition — working in occupied commercial environments without disrupting your neighbours, your building's services or your project timeline. That starts with a pre-start meeting with the building manager to set work windows, containment requirements and communication protocols.

Hoarding is erected at entry points, negative air pressure is maintained, and noise-intensive tasks are scheduled within agreed hours. We then work systematically from one end of the floor to the other — stripping ceilings, pulling partition frames, removing floor finishes and clearing every piece of debris before moving to the next section.

Common areas are vacuumed and wiped down daily to keep the building presentable for other tenants. The floor is handed over as a bare structural shell — clean concrete, exposed soffit and empty utility cores — ready for your fitout contractor.

Frequently asked questions

Can you demolish in a live building?

Yes — it's a specialty. We use hoarding, negative air pressure, agreed work windows and daily common-area cleaning so other tenancies stay open and undisturbed.

How do you manage dust and noise?

Containment and negative air pressure control dust, and noise-intensive tasks are scheduled within hours agreed with the building manager.

What happens to the debris?

Every section is cleared of debris before we move on, and the floor is handed over swept and clean.

Do you coordinate service disconnections?

Yes, we coordinate service isolation and disconnection as part of the pre-start planning.

Available in Cairns, Townsville and Mackay.
