Water Damage Restoration
It’s the structured process of removing water, drying a property back to normal moisture levels, and repairing any damage caused by a leak, burst pipe, storm, or flood. Water Damage Melbourne follows IICRC S500 protocols: inspection, water extraction, drying, monitoring, and reinstatement.
Ideally within the first 24 hours. Water starts causing secondary damage — swelling timber, delaminating cabinetry, and creating conditions for mould growth — within 24 to 48 hours. Our Melbourne team offers a 24/7 emergency response for exactly this reason.
Turn off the water source and power to affected areas if it’s safe, remove valuables from wet areas, and avoid walking through standing water. Don’t use a household vacuum on water. Call a restoration company before moving furniture or throwing anything away, as this can affect your insurance claim.
Small, clean-water spills can often be mopped up and dried with fans. However, anything that has soaked into carpet, underlay, plasterboard, or subfloor usually needs professional extraction and monitored drying, because surface-dry materials can still hold trapped moisture that leads to mould weeks later.
A typical residential job takes 3 to 5 days for structural drying, though this varies with the volume of water, the materials involved, and ventilation. Class 3 or 4 losses (see below) or large commercial properties can take one to two weeks or longer.
Under IICRC S500, categories (1–3) describe how contaminated the water is, from clean supply-line water (Category 1) to sewage or floodwater (Category 3). Classes (1–4) describe how much water has been absorbed and how hard it will be to dry. Any category can occur with any class.
Category 1 is clean water from a sanitary source like a supply line. Category 2 (“grey water”) carries contamination that could cause illness, such as washing machine discharge. Category 3 (“black water”) is grossly contaminated — sewage, rising floodwater, or Category 2 water left untreated for 48+ hours.
Yes. Category 1 water sitting on organic building materials such as carpet, underlay, and plasterboard can begin degrading into Category 2 within roughly 24 to 48 hours as bacteria multiply, which is a major reason we recommend fast professional response.
Truck-mounted and portable extraction units, submersible pumps for standing water, air movers, low-grain refrigerant and desiccant dehumidifiers, moisture meters, thermal imaging cameras, and hygrometers to track relative humidity throughout the job.
It depends on the water category and how long it’s been wet. Clean water (Category 1) caught quickly can often be extracted and the carpet and underlay dried in place. Contaminated water, or carpet that’s been wet more than 48 hours, generally requires the underlay — and sometimes the carpet — to be removed.
Yes. We document every stage with photos, moisture readings, and drying logs formatted to meet insurer requirements, and we can liaise directly with your loss adjuster to support your claim from first contact through to sign-off.
Sudden and accidental water damage — a burst pipe, an appliance failure, an overflowing bath — is typically covered under Australian home and contents policies. Gradual leaks, poor maintenance, and (in many policies) external flooding require separate consideration; always check your Product Disclosure Statement.
Delayed response increases the risk of warped timber floors, swollen skirting boards, mould colonisation, and structural weakening of plasterboard and framing. It can also affect your insurance outcome, since insurers expect reasonable steps to have been taken to minimise damage.
Costs vary with the extent of the damage, water category, and materials affected — a single-room clean-water job might run into the low thousands, while multi-room or contaminated losses cost significantly more. We provide a free on-site assessment and a transparent scope of works before starting.
Yes, our technicians are on call 24/7 across Melbourne and surrounding areas. Early intervention — even just extraction and initial drying set-up overnight — meaningfully reduces the total scope and cost of the restoration.
Flood Damage Restoration
“Flood damage” specifically refers to water from an external source — a river, creek, dam, or stormwater system overflowing onto normally dry land. General water damage covers internal escapes of liquid, like burst pipes. Insurers treat these differently, so identifying the source correctly matters for your claim.
Yes. Floodwater is classified as Category 3 (black water) because it typically carries silt, sewage, chemicals, and bacteria picked up as it travels across land, roads, and drainage systems. Our technicians wear full PPE and follow biohazard protocols whenever floodwater is involved.
As soon as it’s safe to enter the property and floodwaters have receded. We assess structural safety, electrical hazards, and standing water depth first, then begin extraction, contaminated-material removal, sanitisation, and drying.
It depends on your policy. Since 2012, Australian insurers use a standard legal definition of “flood” as water escaping from a river, lake, dam, or similar source. Many home policies include flood cover as standard, but some require a separate flood endorsement — check your PDS or call your insurer to confirm.
Storm and rainwater damage — rain that runs off the ground or overflows gutters — is usually covered under standard policies. Flood is specifically water escaping from a natural or man-made water body. Adjusters sometimes bring in a hydrologist when the source is unclear, since the classification affects whether a claim is paid.
We use submersible pumps and truck-mounted extraction for standing water, followed by manual extraction in hard-to-reach areas. Once bulk water is removed, we begin contaminated material removal, disinfection, and structural drying.
Porous materials that have contacted Category 3 floodwater — carpet, underlay, plasterboard, insulation, particleboard cabinetry, and soft furnishings — generally can’t be sanitised to a safe standard and are removed and disposed of rather than dried and reused.
Yes, we scale our crews and equipment for larger flood events across Melbourne and Victoria, coordinating logistics, drying equipment, and documentation across multiple affected properties at once.
Exposure to floodwater contaminants can cause gastrointestinal illness, skin irritation, and respiratory issues, particularly once mould begins to establish in wet materials. This is why our teams use full protective equipment and why we recommend occupants avoid affected areas until clearance.
Any electrical system, switchboard, or wiring that’s contacted floodwater needs inspection by a licensed electrician before power is restored — we coordinate with electricians as part of the restoration sequence to keep the process safe and efficient.
We photograph and log the damage room by room, record moisture readings before and during drying, keep a log of equipment placement and run-times, and compile a final report suitable for submission to your insurer or loss adjuster.
The Australian Financial Complaints Authority is a free, independent dispute resolution service. If your flood insurance claim is rejected or you disagree with the settlement, you can escalate to AFCA after your insurer’s internal review — AFCA’s decisions are binding on the insurer.
Yes, we can arrange temporary board-up, tarping of damaged roofing, and site security to prevent further water ingress, theft, or weather exposure while the restoration and insurance process is underway.
Rarely. Laminate and floating floors are made from engineered wood products that swell and delaminate once saturated, and Category 3 water contamination makes drying and reusing them unsafe. Solid timber and tiled floors have a better chance of being dried and retained.
Contamination Cleanup
Category 2 (grey water) and Category 3 (black water) under IICRC S500. This includes sewage backups, toilet overflows, floodwater, and any water that’s been in contact with these sources or left stagnant long enough to develop microbial growth.
Full biohazard PPE for technicians, containment of the affected area, extraction of contaminated water, removal of all porous materials that contacted the sewage, disinfection of hard surfaces with hospital-grade antimicrobials, and air scrubbing before the space is cleared for reoccupation.
No. Sewage carries pathogens including bacteria, viruses, and parasites that can cause serious illness. Without proper PPE, containment, and disposal procedures, DIY cleanup risks spreading contamination through the rest of the property and exposing you to health hazards.
Source is the main indicator — sewage backups, toilet overflows involving waste, and rising floodwater are automatically Category 3. Category 1 or 2 water that’s been standing for more than roughly 48 hours, or that has contacted sewage-affected materials, is also reclassified as Category 3.
Waterproof coveralls, chemical-resistant gloves, eye protection, and at minimum an N95-rated respirator, in line with IICRC S500 and Australian workplace safety requirements for biohazard-level work.
Extracted contaminated water and any removed porous materials are bagged, contained, and disposed of in accordance with EPA Victoria waste guidelines, rather than simply tipped into stormwater or general waste.
It’s the application of an EPA-registered disinfectant to hard, non-porous surfaces after contaminated water has been removed, to reduce bacterial and microbial load before drying and reinstatement begin. It’s standard practice on any Category 2 or 3 job.
Non-porous items — metal, glass, sealed hard plastics — can usually be cleaned and disinfected. Soft, porous items like upholstered furniture, mattresses, and soft toys that contacted Category 3 water typically cannot be safely restored and are recommended for disposal.
Biohazard cleanup for these situations is a specialised category of contamination cleanup requiring particular sensitivity, certification, and disposal procedures. If this applies to your situation, contact us directly to discuss the specific service required.
Longer, generally. Material removal, multiple rounds of disinfection, and required drying and clearance testing add time compared with a clean-water extraction and dry-in-place job. A typical contamination job runs from several days to over a week depending on scope.
Many policies cover sudden sewage backups (for example, from a blocked main), but check your PDS, as some policies specifically exclude or sub-limit sewage and drain-related events. We can help document the incident to support your claim either way.
We use physical barriers such as poly sheeting and negative air pressure set-ups with HEPA-filtered air scrubbers to keep contaminated air and materials isolated to the affected zone while extraction, disinfection, and demolition work is carried out.
Assess and stop the source if possible, extract standing water, remove all contaminated porous materials, disinfect remaining surfaces, dry the structure with monitored equipment, and conduct a final inspection before the space is cleared for use.
Structural Drying
The process of removing moisture from a building’s structure — framing, subfloor, plasterboard, concrete slabs — using a combination of air movement, dehumidification, and sometimes heat, until moisture content returns to within normal range for the building’s location and materials.
We measure against a dry standard: unaffected reference material in the same building, then track moisture content with pin-type and non-invasive meters until affected materials fall within a defined range of that reference reading — generally within a few percentage points, consistent with IICRC S500 guidance.
Low-grain refrigerant (LGR) or desiccant dehumidifiers, axial and centrifugal air movers, and in some cases specialty heat or injection drying systems for wall cavities and subfloors, all monitored daily with moisture meters and hygrometers.
Structural materials release moisture slowly, especially dense materials like timber and concrete. Removing equipment too early — even if surfaces feel dry — risks trapped moisture that leads to warping, delamination, or mould growth weeks later.
Properly managed drying shouldn’t cause additional damage. In some cases we need to create small access points — drilling weep holes in skirting or lifting sections of flooring — to reach trapped moisture in wall cavities or under floors, which we explain and document before proceeding.
Often yes, for Category 1 or 2 losses caught early — we use in-cavity drying techniques such as injection drying and controlled air movement. More extensive saturation, contamination, or Class 4 conditions may require selective removal to access and dry hidden moisture.
Psychrometry is the science of air and water vapour behaviour — how temperature, humidity, and airflow interact. Restorers use it to calculate the right combination of dehumidification and air movement needed to evaporate moisture efficiently without over- or under-drying materials.
Daily site visits to record moisture readings across all affected materials, relative humidity and temperature in the space, and equipment performance, with adjustments made to air mover and dehumidifier placement as materials dry unevenly.
Class 4 under IICRC S500 involves low-permeance, low-porosity materials — hardwood floors, plaster, brick, concrete — that absorb moisture deeply and release it slowly. These require specialty drying methods like heat or desiccant dehumidification and can take significantly longer than standard Class 1 or 2 jobs.
Yes — that’s its primary purpose beyond preventing warping and structural weakening. Mould generally needs sustained elevated moisture to establish, so drying a structure back to normal moisture content within the recommended timeframe is the most effective way to avoid a secondary mould problem.
Usually not for residential jobs — drying equipment is noisy but most homes remain liveable, though we may recommend keeping certain rooms closed off. Larger commercial or heavily contaminated jobs may require partial or full temporary relocation.
Dehumidifiers and air movers do draw continuous power over several days, which can noticeably increase your electricity bill for that billing cycle. Reasonable running costs during an insured drying job are generally included as part of the restoration claim — check with your insurer.
Residual moisture trapped in wall cavities, subfloors, or dense materials can continue to cause damage invisibly — warping, corrosion of fixings, and mould growth — which is why we don’t remove equipment until moisture readings confirm the structure has reached target dryness.
Specialised Materials Drying
Materials that don’t respond to standard air-mover-and-dehumidifier drying — solid hardwood flooring, parquetry, natural stone, antique furniture, pianos, artwork, books and documents, electronics, and dense masonry or concrete. These need tailored techniques and often longer timeframes.
Often yes, if addressed quickly. We use specialised floor mats connected to a vacuum drying system that draws moisture directly from beneath the boards, combined with controlled ambient drying, to slow-dry timber and reduce cupping, crowning, or permanent warping.
Rapid drying causes timber to shrink unevenly, leading to cracking, splitting, and gaps between boards. Specialised timber drying deliberately slows the process and monitors moisture gradient through the board’s thickness rather than just the surface.
It depends on the water category and the piece. Clean-water-affected solid wood furniture can often be dried in a controlled environment away from direct heat. Upholstered items exposed to contaminated water are usually not restorable, since fabric and padding retain contamination.
For valuable or irreplaceable items we can arrange specialised freezer-drying or vacuum freeze-drying, which removes moisture through sublimation rather than heat, minimising ink bleed, page sticking, and warping compared with air drying.
Powered-off electronics that haven’t been submerged for long may be salvageable if dried and cleaned promptly by a specialist before corrosion sets in — we can arrange for assessment. Electronics that were powered on when wet, or submerged in contaminated water, are higher risk and often unrecoverable.
Do not turn them on or attempt to dry them with a hairdryer. Disconnect power if it’s safe to do so, and leave them in place for our technicians to assess, since premature power-up can cause a short circuit and permanent damage.
Stone and grout are porous and can trap moisture beneath the surface, particularly over concrete slabs. We use specialised low-and-slow dehumidification, and where needed, moisture mapping to confirm the subfloor has fully dried before any sealing or refinishing work.
Pianos contain hundreds of moisture-sensitive wooden and felt components; even minor water exposure can cause swelling, tuning instability, and rust on strings and hardware. We recommend engaging a piano technician alongside structural drying if a piano has been exposed to water or high humidity.
Sometimes, for Category 1 water caught early, using specialised carpet and pad drying systems that lift and vent air beneath the carpet without full removal. Longer-standing water, contamination, or a saturated concrete slab underneath usually requires the underlay to be removed regardless.
Yes, we provide specialised document and materials drying for commercial and institutional clients, including large-scale freezer or vacuum drying arrangements for bulk paper records where time-sensitive recovery is critical.
It varies by material and the equipment required — freeze-drying documents or vacuum drying timber floors involves specialist equipment and expertise beyond standard structural drying, so it’s usually quoted separately once we’ve assessed what needs saving.
Not always — sentimental or valuable items are often worth the extra effort and cost, but we’ll give you an honest assessment of likely success before you commit, since some materials (particularly contaminated soft goods) simply can’t be safely restored.
Odour Removal
Odours usually come from organic material breaking down — wet timber, carpet underlay, plasterboard paper backing — or from mould and bacteria growing in materials that stayed damp too long. Sewage and floodwater contamination adds further odour sources from the contaminants themselves.
Not always. If moisture allowed mould or bacteria to establish before drying, or if odour-causing compounds have soaked deep into porous materials like underlay or particleboard, the smell can persist even after the structure reads dry — those materials often need to be removed or specifically treated.
Depending on severity: HEPA air scrubbing, activated charcoal filtration, hydroxyl generators (safe for occupied spaces), thermal fogging, and — for the most severe or lingering odours — ozone treatment in an unoccupied, sealed space for a set period.
Ozone is effective at breaking down odour molecules but is not safe to breathe, so treatment is always carried out in a vacated, sealed space, with the area ventilated and aired out fully before anyone re-enters. We handle this as a controlled, monitored process.
Hydroxyl generators produce the same reactive molecules the atmosphere naturally uses to break down odours and VOCs, but at safe concentrations that don’t require evacuating the space — making them useful for occupied homes or businesses where ozone isn’t practical.
Odour treatment alone will mask or temporarily reduce a musty smell, but if active mould growth is the source, the smell will return unless the mould itself is remediated and the moisture source is fixed — we always recommend addressing the cause, not just the symptom.
Sewage odour removal starts with removing contaminated porous materials, thoroughly disinfecting affected surfaces, then applying air scrubbing and, where needed, thermal fogging with an appropriate deodorising agent to neutralise odour-causing compounds embedded in remaining materials.
Yes, particularly the underlay, which acts like a sponge for both moisture and odour-causing bacteria. In many cases the carpet itself can be salvaged and cleaned, but the underlay needs replacing to fully resolve a persistent odour.
Simple air scrubbing or hydroxyl treatment can run over a few days alongside structural drying. Ozone treatments are typically shorter but require the space to be sealed and vacated, plus airing-out time afterward, which we schedule around your needs.
Ozone can degrade rubber, certain plastics, and some dyes with prolonged high-concentration exposure, so we assess room contents and adjust the treatment method or duration accordingly, or recommend removing sensitive items beforehand.
Our core focus is water-damage-related odours, but the same air scrubbing, hydroxyl, and ozone technologies are effective on other organic odour sources. Get in touch to discuss your specific situation.
A persistent musty or earthy smell that doesn’t clear once an area is ventilated and dried is a strong indicator of active mould growth rather than simple residual dampness, and warrants a proper mould inspection rather than odour treatment alone.
Where the odour results directly from an insured water damage event, deodorisation is generally treated as part of the restoration scope and included in the claim — we document it accordingly alongside the rest of the job.
Mould Remediation
Mould spores are naturally present in most environments and only need organic material and sustained moisture — generally more than 24 to 48 hours of dampness — to begin colonising surfaces like plasterboard, timber framing, and carpet underlay.
Visible black, green, or white patchy growth, a persistent musty odour, or recent water damage that wasn’t fully dried are the main indicators. Hidden mould behind walls or under flooring may only show up through a musty smell or a professional moisture and air quality inspection.
For many people, exposure causes only mild irritation, but mould can trigger or worsen respiratory symptoms, allergic reactions, and asthma, particularly in children, older adults, and anyone with existing respiratory conditions. If anyone in the property has ongoing symptoms, we’d recommend they also speak with their GP.
We follow ANSI/IICRC S520, the internationally recognised Standard for Professional Mould Remediation, which Australia has aligned to through the AS-IICRC S520 adoption by Standards Australia. Australia doesn’t yet have its own independent national mould standard, so S520 is the accepted industry benchmark referenced by insurers and dispute bodies like AFCA.
Surface cleaning with household products may remove visible staining but doesn’t address mould growing into the material itself, and disturbing it without containment can spread spores throughout the property. For anything beyond a small, isolated surface patch, professional assessment and remediation is recommended.
Assessment and moisture-source investigation, containment of the affected area to prevent spore spread, HEPA-filtered air scrubbing, physical removal of contaminated porous materials, HEPA vacuuming and antimicrobial cleaning of remaining surfaces, drying, and a final clearance check before containment is removed.
Because if the underlying moisture problem — a leak, poor ventilation, rising damp — isn’t fixed, mould will simply return after remediation, no matter how thoroughly the visible growth is removed. Addressing the cause is as important as the cleanup itself.
If mould has grown into porous materials like paper-faced plasterboard, affected sections generally need to be cut out and replaced rather than cleaned, since mould can penetrate below the surface. Non-porous materials like tile, glass, and metal can usually be cleaned and retained.
Physical barriers — typically heavy-duty poly sheeting — sealed around the affected work area, often combined with negative air pressure using a HEPA-filtered air scrubber, so that disturbed mould spores don’t spread to unaffected parts of the property during remediation.
We conduct a visual and moisture assessment before starting, and where appropriate, independent clearance testing after remediation to confirm the property has returned to a normal air quality baseline before containment is removed — this documentation is also useful for insurance purposes.
A contained single room can often be completed in 2 to 4 days. Larger or more extensive mould problems — particularly those involving HVAC systems, subfloors, or multiple rooms — can take one to two weeks or more.
It depends on the cause. Mould resulting directly from a sudden, insured water event (like a burst pipe reported and acted on promptly) is often covered. Mould from gradual leaks, poor maintenance, or delayed drying after an otherwise-covered event is frequently excluded — always check your PDS.
Recurring mould almost always points to an unresolved moisture source or remediation that didn’t meet proper standard. We recommend an independent ANSI/IICRC S520 assessment to document current conditions, which can also support an insurance dispute if the original work was inadequate.
Yes, HVAC systems can harbour and circulate mould spores throughout a property if condensation or moisture builds up inside ducts or coils. This requires specialised duct cleaning and remediation, and is often overlooked when only visible surface mould is treated.
For a contained, localised job, most residents can generally remain in the rest of the home. Extensive remediation, particularly where air quality is significantly affected or where vulnerable occupants (infants, elderly, immunocompromised individuals) are present, may warrant temporary relocation, which we’ll advise on case by case.
“Mould removal” often implies simply wiping away visible growth. “Remediation” under S520 is the broader, standards-based process — investigation, containment, safe removal, moisture correction, and verification — designed to actually resolve the problem rather than just address its appearance.
Yes — in fact, modern airtight construction can trap moisture indoors more effectively than older, more ventilated homes, making adequate ventilation (bathroom and laundry extraction, fresh air exchange) especially important in newer builds.
Fix any underlying moisture source promptly, run bathroom and laundry exhaust fans during and after use, keep indoor humidity in a reasonable range, ensure good airflow around furniture placed against external walls, and address any leaks or condensation issues as soon as they appear.
Contact our team directly for a free assessment — we’ll inspect the affected area, identify the moisture source, explain the scope of work required under IICRC S520, and provide a clear, documented quote before any work begins.
