What does an underpinning warranty cover in Victoria?

Understanding the split between product cover and the contractor’s workmanship is vital for long-term stability.

Workmanship vs product

Workmanship warranty vs product warranty: what’s the difference?

Workmanship covers the quality of the work carried out on your foundation and footings. Product cover applies to the materials or systems installed.

Industry practice in Victoria often separates these two. Typical workmanship terms run for around ten years. Some resin products carry longer product cover to support ongoing stability and guard against subsidence.

Typical warranty durations and industry benchmarks

Most workmanship guarantees on underpinning tasks extend to about 10 years. Product terms vary by system and manufacturer.

Transferability and proof of cover

Warranties are commonly transferable when you sell the property. Keep the signed contract, certificate of compliance and engineering reports to prove cover.

VBA-compliant certification, council approvals and your cover

We are VBA registered and insured. We coordinate structural engineering reports and council‑compliant methods. This strengthens your claim and ensures the work meets building rules.

Aspect Typical term Notes

underpinning warranty victoria — eligibility, conditions and exclusions

Your property’s long‑term protection begins with simple steps to manage water, trees and ground movement.

Your responsibilities: drainage, plumbing leaks and site moisture control

You must keep gutters, downpipes and stormwater clear. Fix leaking sewer or stormwater lines promptly.
These tasks stop rapid soil change and reduce subsidence risk.

Soil movement, trees and ground conditions that can affect cover

Tree roots can extract moisture and shift ground near footings. Poorly compacted fill or nearby excavation also causes problems.
We assess soil, load paths and surrounding building work to identify triggers that may affect cover.

What documentation you should keep

Record everything. Keep engineering designs, pre‑ and post‑level readings, dated photos, inspection notes and completion certificates.
Note doors, window function and any cracks in walls before and after the project.

When to claim and how assessments are carried out

Claim as soon as you see new movement or recurring issues. Early assessment preserves conditions and lowers cost.
Our process includes on‑site assessment, level surveys and cause analysis focused on soil, water and load paths.

  • Eligibility: Address drainage and plumbing before work.
  • Exclusions: Damage from new excavations, unmanaged leaks or extreme events.
  • Maintenance: Regular gutter and irrigation checks protect the home.

We provide calm, honest guidance, free no‑obligation assessments and coordinated engineering reports. Call Chris: 1300 970 930 or Email Chris: chris@underpinning-melbourne.com.au for clear advice and fixed‑price services from a team with practical experience.

How our certified methods protect your home and your warranty

We use proven structural methods to protect your home and preserve its long‑term stability. Our team selects the right approach for your soil, load and access conditions. We aim to stop movement and restore level quickly.

Concrete underpinning and footing stabilisation

Concrete work provides robust bearing where depth is moderate. We detail footings, staging and testing so the house gains lasting support.

Restumping and reblocking

Restumping relevels floors and improves doors and windows. Reblocking addresses local loss of support across timber homes.

Resin injection, screw piling and targeted repairs

Resin injection lifts slabs and improves ground with minimal disruption. The material is inert and cures fast for same‑day use.

Screw piles reach competent strata in reactive soil to control subsidence. We follow with wall crack repairs as needed and validated fixes.

  • We select methods to maximise stability and protect your warranty.
  • Every job includes engineering reports and a fixed‑price quote.
  • Our team is VBA‑registered and insured for complete compliance.

Clear signs you may need foundation repair today

Small changes like sticking doors can be the earliest indicators of deeper foundation issues.

Watch for obvious cracks in brickwork, render and plaster. Fresh or widening cracks near corners, openings and lintels are important signs.

Cracks in brickwork, render and plaster; sticking doors and windows

Note any new movement. Sticking doors and windows, separated frames or hardware that misaligns usually mean the structure has shifted.

Keep dated photos and notes. Early records speed diagnosis and reduce the scale of repairs.

Uneven or sloping floors, gaps at frames and out-of-level slabs

Check floors with a ball test or a level. Sloping floors, gaps at skirtings, or a visible step at slab joints suggest settlement or subsidence.

These issues often stem from soil moisture change, plumbing leaks or nearby building work. Early assessment stops problems getting worse and typically lowers repair costs.

  • Watch for: fresh cracks, sticking doors, uneven floors and gaps at frames.
  • Common solutions include concrete underpinning, resin injection and targeted slab repairs.

FAQ

What does an underpinning warranty cover in Victoria?

A typical cover protects the workmanship and specified materials used to stabilise footings, slabs and piers. It usually includes repair of defects caused by installation or design, and may cover ongoing structural stability for a fixed period. Coverage varies, so check the certificate for precise limits, exclusions and whether monitoring or maintenance is required to keep the cover valid.

Workmanship warranty vs product warranty: what’s the difference?

Workmanship warranties cover the quality of the contractor’s labour and installation methods. Product warranties cover specific materials such as concrete, piles, resin or anchors. Both are important: workmanship guarantees the job was done correctly, while product warranties protect against material failure. Ask for both documents and their durations before work starts.

What are typical warranty durations and industry benchmarks?

Most industry warranties range from 5 to 25 years depending on the method and materials used. Shorter terms apply to minor repairs; longer terms apply to engineered solutions like screw piles or structural piers. We supply VBA-compliant certificates and clearly state durations in the fixed-price quote.

Is a warranty transferable if I sell my home, and how do I prove cover?

Many warranties are transferable, but terms differ. Transfer often requires notification to the provider and a transfer fee or new inspection. Keep original contracts, engineering reports, certificates and proof of completed maintenance to validate the cover for a new owner.

Do I need VBA-compliant certification and council approvals to keep the warranty valid?

Yes. For major stabilisation works, VBA-compliant documentation and any required council permits are commonly required. These ensure work meets building regulations and protect your cover. We manage certification and liaise with councils as part of the project.

What are my responsibilities for drainage, plumbing leaks and site moisture control?

Owners must control drainage and repair leaks promptly. Poor site moisture — from blocked gutters, downpipes or leaking drains — can cause soil movement and void warranty terms. Regular maintenance and evidence of repairs help if you need to claim.

How do soil movement, trees and ground conditions affect cover?

Reactive clays, expansive soils and large trees can shift the ground. Many warranties exclude damage from neglected trees or excessive vegetation. Pre-work soil assessment and appropriate engineered solutions reduce the risk and are usually reflected in the warranty scope.

What documentation should I keep: engineering reports, levels and photos?

Keep the engineering assessment, site levels, pre- and post-work photos, invoices, permits and the warranty certificate. These documents form your claim pack and demonstrate compliance, existing conditions and completed repairs.

When should I claim and how are assessments carried out?

Claim as soon as you notice progressive issues such as new cracks or movement. We conduct an on-site inspection, record levels and photos, and compare findings with the original reports. If the fault is covered, we proceed with remedial works under the warranty terms.

How do concrete underpinning and footing stabilisation protect my property?

Engineered concrete footings and piers transfer loads to stable strata, arresting further movement. Properly designed and installed footings control settlement and preserve floor levels and wall alignment. We use site-specific designs to ensure permanence.

How do restumping and reblocking help relevel floors and restore door and window function?

Restumping replaces or reinforces failing stumps and piers beneath timber homes. Reblocking lifts and re-levels floors to correct slope and operation of doors and windows. Both methods improve load distribution and long-term stability when done to engineering standards.

Can resin injection be used for slab lifting and ground improvement?

Yes. High-density polyurethane resin can lift settled slabs quickly and stabilise voids beneath concrete. It’s a minimally invasive option for driveways, slabs and some footings. We assess suitability during the site inspection and include it in the fixed-price quote where appropriate.

When is screw piling recommended for reactive soils?

Screw piles are ideal when surface soils are reactive but deeper bearing strata are available. They bypass unstable layers to transfer loads to competent ground. They’re effective for new and remedial works and often carry long-term guarantees when installed to engineer specifications.

Do you repair wall cracks and provide structural engineering reports to validate the work?

Yes. We assess and repair structural cracks using approved methods and prepare engineering reports that validate the remedial design. These reports support warranty claims and council approvals when required.

What is included in your promise of VBA-registered, insured, fixed-price quotes and minimal disruption?

We provide VBA-registered documentation, public liability and workmanship insurance, and a clear fixed-price quote. Our teams plan to minimise disruption, protect landscaping and complete works efficiently. We outline timelines, site management and clean-up in the contract.

What clear signs indicate I may need foundation repair today?

Watch for widening cracks in brickwork or render, new plaster cracks, sticking or jamming doors and windows, uneven or sloping floors, and gaps at frames. Early assessment prevents escalation and preserves property value.

How quickly can you assess and begin a project?

We typically schedule an assessment within days for urgent issues. After inspection, we provide an engineer’s report and fixed-price quote. Once you approve, we book works based on scope, council timing and weather conditions.

How much do foundation repairs usually cost and what affects price?

Costs vary with method, site access, soil conditions, extent of damage and required permits. We give a fixed-price quote after inspection and testing. That quote covers labour, materials, engineering reports and required certification.

How do I maintain my property after works to protect the warranty?

Maintain gutters, downpipes and site drainage. Repair plumbing leaks promptly. Follow any monitoring schedule in the warranty and keep records of inspections and repairs. Regular maintenance helps ensure long-term protection.
