Kiama Homeowners Trust US for Foundation Services

Noticing dips in your floor, cracks creeping along the walls, or doors that no longer shut the way they used to?


 In Kiama, many homes around the town centre and streets like Terralong, Manning, and Bong Bong Street date back to the town's quarrying era, and the coastal moisture rolling in off Blowhole Point and Kiama Harbour can put real stress on ageing timber stumps over time. Tackling those small issues early often saves a much bigger repair bill later.


At Wollongong Restumping, we're local specialists who understand the area's specific conditions, including the heritage weatherboard cottages throughout Kiama's town centre and the challenges of restumping older coastal homes without disturbing their original character. We offer free on-site assessments, clear quotes, and tailored solutions to stabilise and level your home. From restumping and underpinning to slab jacking, our licensed team restores your foundation so you can feel confident about your home's safety, comfort, and value.

Our Specialised Foundation Repair Services in Kiama

Wollongong Restumping provides mobile foundation repair services throughout Kiama and the wider South Coast region. Our expertise spans the full range, from minor sinking floors to major structural concerns. We're fully equipped to help with:

Restumping & Reblocking of House

Many of Kiama's older homes, including the weatherboard cottages around the town centre, sit on timber stumps that weaken over time. Moisture, pests, and shifting soil all take their toll and gradually undermine your foundation. Our restumping or reblocking service lifts your home and replaces the damaged stumps with new concrete or treated-timber ones. We set each stump to the correct height and pack it securely, so your floors and walls return to level.

House Leveling Process

Uneven, sinking, or sloping floors are a clear sign your foundation has moved. Our re-levelling service fixes this by lifting and adjusting the affected sections back to their proper level. We inspect your subfloor for moisture fluctuations, repair or replace any weak supports, then pack everything securely to lock in the new level.

Learn more

Foundation Underpinning

Our mobile inspection experts visit first to assess the condition and give you an idea of the best option for your budget, either stabilising the base by extending the existing footings deeper into firmer ground or widening them to spread the load more evenly. For older Kiama homes on shallow or ageing footings, we also provide slab support systems that anchor your structure into the firm layers below the surface.

Learn more

Slab Jacking Process

For Kiama homes built on concrete slabs that have settled or cracked due to moisture or ground movement on sloping ground, slab jacking (also known as concrete jacking, foam concrete lifting, or concrete lifting) is a more efficient, lower-cost solution. The process involves injecting a specialised polyurethane grout mixture beneath the slab to gently lift and stabilise it, filling voids and restoring the slab to its correct level.

Foundation Crack Repair

Visible cracks in walls, floors, or the foundation are a sign of ground movement or stress in your home's structure. We specialise in pinpointing the cause of these cracks and repairing them correctly, backed by our detailed inspection at no cost. We don't just patch over the surface; our team seals and stabilises the affected areas, reinforces weakened sections, and, where needed, carries out concrete cancer repairs to stop the deterioration spreading.

Learn more

Foundation Stabilization

Before any foundation repair begins, we carry out a full structural inspection to pinpoint exactly what's happening beneath your property, assessing soil condition and pier strength to map out your options. Our experienced team uses advanced tools to measure movement, check for hidden damage, and understand the cause of any cracks or soil settlement. From this inspection, we develop a repair plan that addresses the root issue.

Benefits of Restumping and Foundation Repairs in Kiama

Investing in professional restumping and structural repairs is one of the most effective ways to protect your home's safety, strength, and value before ground settlement takes hold. This matters in parts of Kiama, where older weatherboard cottages and coastal moisture exposure can make properties more prone to movement. A stable base keeps your home level, secure, and free from the cracks, sagging floors, and sticking doors that come with movement. Ignore what's happening under the house, and it can quickly escalate into serious damage, rising repair costs, and safety concerns.

Improved Foundation

Cracked, damaged, or deteriorated stumps and foundations directly compromise your home's stability and call for professional restumping. Our foundation repair and underpinning services make these supports robust again, preventing issues like sagging floors, misaligned doors, and wall cracks.

Safe Stabilization

A compromised foundation can pose serious safety risks, including potential collapse or major structural failure during extreme weather. By stabilising your home's foundation, we remove these hazards and create a safer living space built for long-term durability.

Property Value

Foundation problems are a major red flag for buyers and can significantly devalue your property. Professional repairs not only resolve the issue but signal to the market that your home is well-maintained and structurally sound, lifting its market appeal and value.

Further Foundation Damage

Small cracks or minor settling can quickly escalate into major structural damage if left unaddressed. Early intervention through restumping, underpinning, or re-levelling stops these minor issues from becoming extensive, expensive ones, saving you money in the long run.

Better Energy Efficiency

Foundation movement can open gaps and cracks in your home's structure, letting conditioned air escape and outside air in, and making your heating and cooling work harder. A stable foundation helps seal your home, improving insulation and potentially reducing your energy bills.

Secure Home

Perhaps the most valuable benefit of all is the peace of mind that comes with knowing your home's foundation is secure, with no further repairs hanging over you. Our complete solutions and 10-year warranty mean you can live comfortably, without the constant worry.

Signs Your Kiama Home May Need Foundation Repair

Spotting the early warning signs of foundation problems is key to preventing damage and costly repairs. Given the age of much of Kiama's housing stock and its coastal exposure, homes here can be particularly susceptible to foundation stress. If you notice any of the following, it's well worth booking a professional assessment with Wollongong Restumping:


  • Deteriorated or rotted stumps: Especially common in Kiama's older homes, timber stumps can decay from prolonged moisture, fungal growth, or pest activity, leaving the base unstable.
  • Cracks in walls, floors, or ceilings: Watch for distinctive zigzagging cracks in brickwork, plaster, or drywall, particularly around door and window frames. Cracks in concrete slabs or tiled floors are also indicators.
  • Sinking or uneven floors: A noticeable slope or dip in your floors, or areas that feel unusually spongy underfoot, often points to foundation settlement.


  • Sticking doors and windows: As the foundation shifts, door and window frames fall out of alignment, making them hard to open or close smoothly.
  • Water damage or leaks near the foundation: Poor drainage or runoff from the surrounding hillside can lead to water ingress, worsening soil problems and structural damage. We can also assess your home's waterproofing.
  • Gaps between walls and ceilings or floors: These appear as the house settles unevenly and structural elements begin to pull apart.


Together, these point to underlying foundation issues, usually driven by soil movement, tree-root intrusion, poor drainage, or prolonged moisture. Ignoring them risks your home's safety, comfort, and overall value.



Restumping or Underpinning? How We Help You Save Money

Not every compromised foundation needs a complete replacement. At Wollongong Restumping, our experienced repairers inspect the damage to your property and guide you toward the most affordable, practical solution. Our goal is to save you money wherever a repair is a safe and viable option, while ensuring your home's long-term stability.

When a House restumping Is Possible


Foundation repairs are often feasible for issues that are localised and haven't seriously compromised the overall structure. We typically recommend a repair when there's:


  • Minor settling: Slight, localised settlement that has stabilised and isn't progressive.
  • Small, non-structural cracks: Hairline cracks in non-load-bearing walls or concrete slabs that don't indicate significant movement.
  • Deteriorated but stable stumps: Individual timber stumps showing signs of rot or pest damage while the surrounding foundation remains sound.
  • Localised water damage: Issues caused by poor drainage that have led to minor erosion or surface damage, without affecting the deeper foundation.

When a House Restumping Is Necessary


Where the damage is extensive, progressive, or poses a significant safety risk, a more substantial solution, such as resin injection or screw piling, is usually required. A replacement or structural intervention is typically needed when there's:


  • Extensive cracking: Large, active cracks in load-bearing walls, ceilings, or the foundation itself, indicating significant structural movement.
  • Compromised structural integrity: When the foundation has lost its ability to support the structure above due to subsidence or ground movement.
  • Progressive damage: When existing cracks or settlement are actively worsening over time, signalling ongoing foundational issues.
  • Major water ingress: Persistent water problems leading to significant erosion, soil washout, or long-term saturation around the foundation.

Frequently Asked Questions – Kiama Foundation Services

Here are some common questions we receive about foundation repair and restumping in the Kiama area:

  • Do you offer fast foundation repair in Kiama?

    We respond quickly to mangerton enquiries and aim to book your free on-site inspection at the earliest convenient time. The foundation work itself is scheduled once we've assessed the property and agreed on a plan, since the scope varies from home to home but we always work to minimise delays and disruption.

  • Can a foundation crack be repaired, or do I need a full restumping?

    It depends on the cause and extent of the cracking. Hairline, non-structural cracks and localised, stabilised settlement can often be repaired. Large, active cracks in load-bearing walls or signs of ongoing movement usually call for a more substantial solution like underpinning or restumping. Our free inspection determines which applies to your home, and we'll always recommend the most cost-effective safe option.

  • How much does foundation repair cost in Kiama?

    Cost depends heavily on the type of issue, the size and slope of your block, soil conditions, and the method required (restumping, underpinning, slab jacking, or crack repair). Because every property is different, we don't quote a flat figure — instead, we provide a free on-site inspection and a transparent, itemised quote with no hidden fees, so you know exactly what you're paying for before any work begins.

  • Is a soil test necessary before foundation repairs?

    In many cases, yes. Testing the soil helps us understand what's driving the movement, particularly useful in Kiama, where reactive clay soils and coastal moisture are common. It lets us choose the most effective, long-lasting solution rather than just treating the symptoms. We'll advise whether your property needs one as part of the inspection.

  • Does restumping a heritage or older cottage in Kiama require anything different?

    Yes, often. Many Kiama properties sit within heritage conservation areas or are individually heritage-listed. Our team factors this into the assessment and takes care to preserve original features, cladding, and character wherever possible while still bringing the structure up to a safe, stable standard.
