Raise Your Home on Steel Posts Across Cairns, FNQ

We lift homes across Cairns and FNQ onto steel, galvanised, or hot-dipped posts.

What House Lifting Involves and When You Need It

Flood Resilience for Far North Queensland Properties

Cairns and surrounding FNQ towns sit within declared flood plains. Lifting a home by even half a metre above Q100 flood level protects the structure, its contents, and the owner's insurance position. Councils increasingly require minimum floor heights on rebuilt or significantly altered dwellings, making a structural lift the most direct path to compliance.

Creating Usable Living Space Below the Floor

Lifting a home from its original stump height to a full 2.4 m clearance below the bearers converts the sub-floor into a legal, insurable habitable space. That might be a garage, laundry, or living room, without adding a second storey or acquiring more land. We carry out these lifts regularly across Cairns and surrounding FNQ suburbs.

Upgrading from Deteriorating Timber Stumps to Steel or Galvanised Posts

This is not standard restumping. It is a structural lift that simultaneously replaces post material and raises the home to a new height. The lift also allows full access to the bearer frame for inspection and repair before the new posts are installed, giving us the opportunity to identify and address any structural issues before the home is lowered onto its new supports.

Choosing the Right Post Type for Your FNQ Home

Steel Posts – Strong, Direct, and Cost-Effective

Uncoated steel RHS posts are the standard structural option for house lifting across Cairns and FNQ. They meet Queensland building code requirements for structural loads. In low-corrosion environments and on properties that allow for routine maintenance, steel posts perform reliably. In coastal or high-humidity sites, surface treatment becomes more important – which is where galvanised and hot-dipped options apply.

Galvanised Steel Posts – Corrosion Resistance for Coastal and Tropical Sites

Galvanising applies a zinc coating to the steel, significantly slowing corrosion in humid and salt-affected environments common across Port Douglas, Palm Cove, and coastal Cairns suburbs. For most FNQ residential sites, galvanised posts extend the service life of the subfloor structure without the premium cost of hot-dipped. We recommend galvanised as the minimum standard for any home within 1 km of the coast or in a classified flood-affected area.

Hot-Dipped Steel Posts – Maximum Protection for High-Exposure FNQ Sites

Hot-dipping applies a thicker, more uniform zinc layer than cold galvanising, making it the appropriate choice for homes in direct tidal or flood-inundation zones, beachfront and estuarine properties, and sites with high soil acidity – conditions found throughout the Trinity Inlet and Mission Beach corridors. Hot-dipped posts are specified by some council requirements for certain flood overlay categories. We assess the site before recommending a post type – call 0418 730 039 to discuss your specific property.

The House Lifting Process from Structural Assessment to Completion

Step 1 – Structural Assessment and Quote

We visit the site, inspect the existing bearer and joist frame, assess stump condition, soil type, and access, and measure the required lift height. This assessment determines the scope of structural work, the post type recommendation, and the basis of the written quote. We carry out this assessment before any contract is signed.

Step 2 – Council Approval and Building Certification

Raising a home beyond a specified height threshold in Queensland requires a development application or building approval from the local council and a licensed building certifier. We advise on whether your project requires formal approval and can recommend experienced certifiers familiar with Cairns Regional Council and Douglas Shire Council requirements.

Step 3 – Preparation and Service Disconnection

Before lifting begins, water, electricity, and sewerage services are disconnected by the relevant licensed contractors. External steps, handrails, and any protrusions that would interfere with the lift are removed. The site is cleared and jacking positions are marked.

Step 4 – Hydraulic Lifting and Post Installation

We lift the structure incrementally using hydraulic jacks positioned at calculated bearer locations. Once the home reaches the target height, new steel, galvanised, or hot-dipped posts are installed and secured to the bearer frame and footings. The structure is lowered onto the new posts and checked for level across the full floor plate before jacks are removed.

Step 5 – Reinstatement and Final Inspection

Services are reconnected, steps and access structures are rebuilt to the new height, and a final structural inspection is carried out. We do not consider a job complete until the home is level, the new posts are fully secured, and the site is cleared of equipment and waste.
