4GeoFix
GeoFix works out of Hobsonville on ground stabilisation and structural remediation, using resin injection to raise and re-level sunken floors, slabs and footings rather than excavating for traditional underpinning. It is the engineering division of the Grace Foundation Group and takes on residential, commercial, council and infrastructure work. Note that traditional repiling and drainage are handled by its sister brand, Grace Foundation Solutions, so GeoFix is the right call when the problem is the ground rather than the piles.

How to Choose the Right Foundation Repair Company in Auckland
- Check the work will be carried out or supervised by a Licensed Building Practitioner, since foundation work on a dwelling is restricted building work.
- Match the method to the problem. Rotten timber piles need repiling, while a sinking slab on reactive clay is often better suited to resin injection or engineered underpinning.
- Ask who handles the building consent, the engineer’s design and the council inspections, and whether that is included in the quoted price.
- Confirm the diagnosis covers the cause, not just the symptom. Leaking pipes, poor drainage and tree roots all keep a foundation moving after it has been re-levelled.
- Get the guarantee in writing and ask what it covers, how long it runs, and whether it transfers if you sell the house.
Frequently Asked Questions About Auckland Foundation Repairs
What are the warning signs my foundations need repair?
The common signs are sloping, bouncy or noisy floors, cracks in interior linings, plaster, brickwork or concrete, doors and windows that stick or will not latch, and gaps opening at skirtings and joinery. Older villas and bungalows on timber piles tend to show movement through the floor first, while slab homes usually show it as wall cracking.
Why do Auckland houses move in the first place?
Much of Auckland sits on reactive clay that swells in wet weather and shrinks in drought, so footings settle as moisture levels change. Leaking or blocked pipes, poor site drainage, tree roots seeking water, and excavation on a neighbouring property are all frequent triggers. Older homes are more exposed because the original footings are often smaller than a modern equivalent.
Do I need a building consent for foundation work?
Usually yes. Repiling, underpinning and structural foundation repair are generally restricted building work requiring a consent from Auckland Council and, in most cases, an engineer’s design. Reputable contractors handle the application and the inspections as part of the job. You can read what counts as restricted building work at building.govt.nz.
How do I check a contractor is licensed?
Restricted building work must be carried out or supervised by a Licensed Building Practitioner, and you can look up any practitioner’s licence class and status on the public register at lbp.govt.nz. Ask for the practitioner’s name rather than the company name, since the licence is held by the individual.
Do I have to move out while the work is done?
Often not. Partial repiling, underpinning and resin injection are generally carried out from under or outside the house, and many jobs are completed with the household still living there. A full repile is the main exception, since it usually requires the house to be lifted and the family to move out for the duration.
How long does foundation repair take?
It depends on the method and the extent of the damage. Resin injection re-levelling is frequently finished in a day or two. A full repile runs from several days to several weeks depending on the size of the house, the ground conditions and access to the site. Consent processing time sits on top of that.
Will my insurer or a future buyer ask about the piles?
Quite possibly. Many New Zealand insurers require the piles on an older home to be replaced as a condition of cover, and a building report will pick up sloping floors or foundation cracking during a sale. Getting the work consented and documented protects you on both counts.
Should I fix the foundations before renovating?
Yes. Renovating on top of a foundation that is still moving risks cracking the new work, and larger renovations often need a sound subfloor to gain consent. Having the subfloor assessed before you start is cheaper than redoing finished work later.
How We Chose the Best Foundation Repairs in Auckland
Every business in this guide was found by searching for foundation repairs in Auckland, then checked against its own website. Names, addresses and phone numbers are taken from the business’s own site rather than a directory feed, so what you see here is what they publish themselves. We also check that each one is actually based in or genuinely serving Auckland, rather than a national operator running a local landing page. A business with no website of its own is not listed, because there is no primary source to verify it against.
