DIY vs Professional Footing Installation in Victoria

Owner-builders can supply and install some BMSA components themselves on simple Class 10 jobs, but house restumping and anything needing a building permit or engineer certificate in Victoria should be installed by a licensed professional. Wrong depth, torque or soil class is how stumps fail. Easy Footings supplies only, or supplies and installs.

When DIY or Owner-Builder Supply-Only Is Reasonable

Supply-only is a genuine option. Easy Footings sells BMSA Footing Solutions components so an owner-builder or experienced tradesperson can install them on a simple job. The usual fit is a Class 10 accessory structure — a deck, garden shed, carport or similar non-habitable building — where a structural engineer has already issued drawings and your building surveyor has accepted who will install the footings.

That still means following the drawings: the specified product, depth, spacing and connections. A screw pile or driven stump that stops short of the design depth, or is wound in without meeting the specified torque, is not the footing the engineer certified. Soil class matters as much as the steel. A Class A or S sandy site is a different install from Melbourne’s reactive clay.

Reasonable DIY or owner-builder territory looks like this:

• A low-level deck or shed on a relatively level block, with engineer drawings in hand
• You (or your carpenter) can handle the driver or jackhammer and the manufacturer’s install method
• Services have been located, and you are not working under a live house
• The building surveyor has confirmed any permit, exemption or owner-builder consent that applies

For deck detailing see the deck footing installation guide. For sheds, see shed footings in Victoria. Product pages list SKU prices and 14-day returns on unused goods — see the purchase terms for supply-only conditions. Easy Footings does not accept liability for third-party installation of supply-only products; that responsibility sits with the person who installs them.

When You Must Use a Professional

Hire a licensed professional stump installer for anything that holds up a house, or that a surveyor will treat as structural work needing a permit and an engineer certificate. In practice that is most jobs people search for when they type “install stumps yourself Victoria”.

• House restumping (full or partial). The house has to be jacked, old stumps removed, and the structure lowered onto new ones. That is not a weekend job. See the Melbourne restumping cost guide.
• New dwelling stumps — Class 1 houses and new stumped floors.
• Granny flats and secondary dwellings, which are habitable buildings, not Class 10 sheds. See granny flat footings in Victoria.
• Reactive clay (much of Melbourne’s west and north, and large parts of regional Victoria). Depth and torque have to match the soil class or the stump will heave or settle. Adjustable steel is the usual professional upgrade on clay, not a DIY guess.
• Sloping blocks, where pile lengths and cut-and-fill change from grid to grid.
• Work near trees, where root zones and Tree Protection Zones constrain how you found.
• BAL-rated (bushfire) sites, where the footing and stump specification is part of the BAL package.
• Adjoining property — footings on or near a boundary, or work that could undermine a neighbour’s footing or fence. Victorian building work that protects adjoining property is a common permit trigger; do not assume an exemption.

If you are unsure which side of the line you are on, treat it as a professional job and ask a building surveyor. That is cheaper than pulling uncertified stumps later.

Permits, Engineers and the VBA

This is a high-level overview, not legal advice. Confirm the path for your site with a registered building surveyor (council or private) and, where required, the Victorian Building Authority (VBA) owner-builder process.

In Victoria, most building work involving footings needs a building permit before work starts. That includes new homes, extensions, most elevated decks, restumping and relevelling, and sheds or outbuildings over the size and siting thresholds. Some minor works can be exempt — a small garden shed or a very low deck, for example — but thresholds vary by council. Do not assume an exemption.

The surveyor issues the permit, inspects the work, and (for restumping) typically issues a certificate of final inspection. Footing design may need a structural engineer certificate, especially on reactive clay or where an alternative (non-deemed-to-comply) system is used. A soil test may be required if the property does not already have one. Replacement and new stumps must be designed for the site classification under AS 2870.

Owner-builders in Victoria may need owner-builder consent for work above certain cost or complexity thresholds. The VBA publishes the current rules; we do not restate dollar limits here because they change. Ask your surveyor what consent, if any, applies before you order steel.

For the permit and certification picture in plain English, see Victorian building footing regulations and AS 2870 explained.

Risks of DIY Restumping

DIY restumping is the job we are asked about most often, and the one we advise against. The risks are structural, not cosmetic.

• Jacking. The house is lifted off the old stumps with hydraulic jacks, progressively and in sequence. Uneven lift cracks plaster, twists frames, and in the worst case drops a section of floor.
• Services. Plumbing, gas, electrical and sewer lines run under most Melbourne weatherboards. A jack, a driven pile or a broken concrete stump can hit them.
• Collapse. Temporary supports that are short, soft or badly placed fail. That is how people are injured under houses.
• Wrong depth, torque or soil class. A stump that looks “in” but has not reached the engineer’s founding layer will settle or heave with the next wet winter. That is the usual failure mode, not the steel itself.
• Insurance. Stump deterioration from age, rot or gradual soil movement is treated as wear and tear and is excluded by most Australian home policies. Unlicensed or unpermitted structural work can also leave you uninsured if something fails. Check your PDS and talk to your insurer; do not assume cover.

Restumping is also the job where a professional crew finishes in days with the right gear. Concrete-free driven steel can be lowered the same day. The saving from doing it yourself is small against a failed floor or a stop-work order.

What Easy Footings Supplies and Installs

Easy Footings Pty Ltd (ABN 44 689 644 175) supplies and installs concrete-free steel footing systems manufactured by BMSA Footing Solutions across Melbourne and regional Victoria:

• RapidStump — driven steel, concrete-free. Used for restumping and new stumps. Compact equipment works in confined sub-floor space.
• StumpRite — adjustable galvanised steel stumps with up to 120 mm of screw height adjustment. The usual choice when future re-levelling on clay matters. See also adjustable stumps in Victoria.
• SurePile — heavier helical screw piles for higher loads, more reactive clay, sloping blocks and modular or container buildings.

You can buy components supply-only (owner-builder or your own installer) or have Easy Footings supply and install. Unused goods can be returned within 14 days as already stated on the product pages and in the purchase terms. Call 0419 994 555 or use the contact form if you want an assessment rather than a parts list.

Component Prices vs Installed Cost

Do not confuse a product SKU with an installed stump. The live RapidStump offer is $122 ex GST. That is a component price, not the cost to restump a house.

Installed restumping in Melbourne and regional Victoria in 2026 sits in the same bands as the restumping guide:

• Per stump: $500–$1,000+ (supply and install)
• Partial restump (10–20 stumps): $5,000–$15,000
• Full restump (typical weatherboard, 40–60 stumps): $20,000–$50,000

Individual StumpRite and SurePile accessory SKUs have their own ex-GST prices on the product pages. Access, soil class, engineering, permits and whether you choose driven RapidStump, adjustable StumpRite or helical SurePile all move an install quote within the band. We do not publish tighter per-stump install prices because sites vary too much for a single figure to be honest.
