Flood Damage Restoration in Brisbane: how the job actually runs.
Brisbane has a long memory for floods. January 2011 and February 2022 put the same river suburbs underwater — West End, Toowong, Indooroopilly, Jindalee, Goodna, central Ipswich — and the creek catchments in between flood more often than the river does. In February 2022 some suburbs recorded around 700 mm of rain in three days, and Kedron Brook, Enoggera Creek and Bulimba Creek were in houses well before the river peaked. Flood damage restoration is what happens after the water leaves and before the rebuild begins, and it is the stage most people get wrong.
What flood damage restoration involves
Flood water is Category 3 under the IICRC S500 standard: grossly contaminated, the same classification as sewage. That single fact drives everything. Porous materials that have absorbed Category 3 water cannot be cleaned to a safe standard, so the job is not “dry the house” but “strip, clean, treat, dry, rebuild”.
Pump-out and extraction deals with what is left after the water recedes: pooled water in low rooms, the subfloor, and the silt that holds it.
Strip-out removes carpet and underlay, the lower section of gyprock, wet insulation, particleboard flooring and cabinetry that sat in the water, and any soft furnishings. Everything is photographed, listed and bagged for disposal — the list becomes part of the claim.
Cleaning and antimicrobial treatment follows. Slabs, timber framing, subfloor bearers and joists are pressure cleaned to remove silt and then treated. Silt is the enemy here: it hides contamination and moisture, and when it dries it becomes airborne.
Structural drying then runs seven to ten days on a typical flooded home, with air movers and LGR dehumidifiers sized to the load and readings logged daily.
Rebuild starts only when moisture readings meet dry standard. Closing walls early over damp framing is the most expensive mistake in flood recovery.
Flood cleanup versus water damage cleanup
| Burst pipe (Cat 1) | Creek or river flood (Cat 3) | |
|---|---|---|
| Carpet | Often dried and kept | Always removed |
| Gyprock | Dried in place if fast | Cut 300–600 mm above tide line |
| Timber framing | Dried | Cleaned, treated, dried |
| Contents | Mostly kept | Porous items disposed of |
| Typical drying | 3–5 days | 7–10 days |
| Typical cost | $2,000–$6,000 | $6,000–$15,000+ |
The first hours after the water drops
- Do not go back in until it is safe. Flood water hides open drains, debris and displaced snakes. Power must be confirmed off at the meter, and if water rose above the power points an electrician has to clear the house before it is re-energised.
- Photograph the tide line on walls, fences and cupboards, and the outside of the house showing where the water came from. The path of the water is what decides flood versus storm on your claim.
- Open the house up. Doors, windows, under-house access. Airflow starts drying and slows mould.
- Move what is salvageable to a dry area. Hardwood furniture, sealed containers and metal items usually survive. Mattresses, upholstered lounges and particleboard do not.
- Wear gloves, boots and a P2 mask for anything you handle.
- Contact us and your insurer the same day. Mitigation costs are generally covered when documented, and the documentation starts with those first photos.
Insurance and the flood definition
Since the Insurance Council of Australia adopted a standard definition in 2012, “flood” means water escaping the normal confines of a river, creek, lake, dam or stormwater channel. Everything else — rain through a damaged roof, run-off crossing your block — is storm, and storm is covered on almost every policy. Flood cover is optional on many Brisbane policies and often carries a higher excess or is excluded on properties with a flood history.
Where a claim gets contested is the path of the water. If Norman Creek came up through the stormwater drain and across your yard, is that flood or stormwater run-off? Our reports record the source, the entry point and the tide line, and we log every moisture reading and every item removed. That record is what the assessor works from, and it is what protects you if the first decision is wrong.
Brisbane, Ipswich and Logan: flood corridors and housing
River suburbs. West End, New Farm, Toowong and Indooroopilly mix raised Queenslanders with post-war brick and modern apartments. The Queenslanders generally fare best — hardwood floors and VJ boards clean and dry — while ground-floor apartments and enclosed under-house rooms take the worst of it.
Creek catchments. Kedron Brook and Cabbage Tree Creek on the northside, Bulimba and Norman Creeks on the southside, Moggill and Enoggera Creeks in the west. Creek floods rise and fall in hours, so the water is in the house for less time, but it carries more silt and debris and it often arrives with a storm that has also damaged the roof.
Ipswich and the Bremer. Central Ipswich and Goodna have a mix of Queenslanders and 1960s–80s brick homes on slab. The Bremer peaks later than the Brisbane rain, which catches people out. Springfield Lakes and Redbank Plains are newer estates where the risk is flash flooding and stormwater surcharge rather than the river, and particleboard floors on low-set slabs swell fast.
Logan. Beenleigh and Shailer Park sit on the Logan and Albert Rivers; Logan Central and Springwood drain to Slacks and Scrubby Creeks. Brick-and-tile homes on slab dominate, which means slow drying under tiles and wet bottom plates behind the gyprock.
Why the drying takes as long as it does
A flooded slab home is Class 4 drying under S500 — the materials are holding a lot of water and releasing it slowly. Concrete can hold water for weeks. Timber framing that reached 30 per cent moisture content has to come down below 18 per cent before it is safe to close in, and in Brisbane’s 70 to 80 per cent summer humidity that does not happen with open windows alone. Air movers keep the surface evaporating, LGR dehumidifiers pull the moisture out of the room air, and we read the framing with pin meters every day until the numbers are right.
What flood damage restoration costs
A flooded home with multiple rooms affected by Category 3 water typically costs $6,000 to $15,000 or more to strip, clean, treat and dry, before any rebuild. The drivers are the floor area affected, how high the water rose, how long the house sat wet before work started, the housing type (tile over slab is slowest), and how much contents work is involved. Call-out and assessment is $300 to $600.
After a major event, restoration crews across South East Queensland are stretched, and the homes that get attention first are the ones that have already been made safe, opened up and documented. Do those things today and get in touch — we cover Brisbane, Ipswich and Logan.
